What Meloxicam does in the body

Meloxicam blocks the enzymes that make prostaglandins, the messengers that make an inflamed joint hurt and swell.

What distinguishes it is timing rather than mechanism: it is absorbed slowly, peaks four to five hours after a dose, has a second smaller peak around twelve hours because the liver recycles it through the bile, and takes about five days of daily dosing to reach a steady level. That makes it a good maintenance drug for arthritis and a poor choice for pain you want gone this afternoon. It is often described as preferring the inflammation enzyme over the housekeeping one, which is supported by laboratory work and is not a claim its prescribing information makes.

Why people take it. Arthritis pain and inflammation, taken once a day

What happened in people

Gastrointestinal adverse events 13% against diclofenac’s 19% over 28 days in 9,323 patients, with hard ulcer complications not significantly different (5 against 7)

Source-linked record

Where this came from

A person wrote this into the record with the study named beside it. No reviewer has signed it off.

The recorded finding that sits closest to something a person would notice. Written into the record, not signed off, and it carries no population or interval.

The limit that matters most

Very widely prescribed for acute musculoskeletal and dental pain, a use its oral label does not cover

Where it acts
The cyclooxygenase channel of COX-1 and COX-2 in inflamed synovium, gastric mucosa, kidney and platelets, held for a long time — the elimination half-life is about 20 hours
Kind of result
The kind of result is not recorded
Supervision
Professional supervision is normally required. A regulator classifies this substance in a way that restricts how it is supplied.

Words this page uses

Four words worth knowing first

Chosen from what this page shows, with each one explained before the word it depends on.

Stand-in result

A stand-in result is a number measured because the real result takes too long.

A picture of it, and where the picture fails

It is like judging a journey by the speedometer rather than by arriving.

Where that stops being true. Speed does predict arrival. Many stand-in results do not predict the real one.

What people get wrong. A stand-in result is often reported as the result itself.

A surrogate endpoint substituted for a clinical endpoint, valid only where the substitution has been shown to hold.

Randomisation

Randomisation means chance decides who gets which treatment.

A picture of it, and where the picture fails

It is like a coin toss deciding the groups.

Where that stops being true. A coin toss is fair once. Fairness here comes from doing it for everyone.

What people get wrong. It is thought to make groups identical. It makes them similar on average, including on things nobody measured.

Allocation of participants to arms by a chance process, so that unmeasured factors are balanced in expectation.

Confidence interval

A confidence interval is the range the true answer is likely to sit in.

A picture of it, and where the picture fails

It is like a weather forecast giving a range rather than one number.

Where that stops being true. A forecast range covers tomorrow. This one covers what the study could resolve.

What people get wrong. The middle number is read as the answer. A range crossing zero means no change is still possible.

An interval estimate that would contain the true parameter in a stated proportion of repeated studies.

Pathway

A pathway is a chain of steps inside a cell, each one setting off the next.

A picture of it, and where the picture fails

A pathway is like a row of dominoes.

Where that stops being true. Dominoes fall one way. Pathways loop back and can switch themselves off.

What people get wrong. Changing one step is read as changing the outcome. Other steps often absorb it.

An ordered series of molecular interactions producing a defined cellular change.

What was measured, goal by goal

One row for each goal a registered study measured something for. One column for each kind of thing that could be measured.

Registered studies list 40 outcome measures that RNAWiki could read. A registered study says what someone planned to measure. It does not say what they found. 0 of the matched studies tested this substance, and 0 posted a result.

There is no single score. A strong test result and a weak life result are different facts.

Goals down the side, kinds of measurement across the top. Each cell says what kind of thing was registered, not what was found.

What this does not prove. Meeting one endpoint in one population does not carry to other goals or other people.

The limits of this study, and where it came from

Main limit. Efficacy on visual analogue scales consistently favoured diclofenac, with 95% confidence intervals not crossing zero, and significantly more patients discontinued meloxicam for lack of efficacy (80 of 4,635 against 49 of 4,688, P<0.01). The comparator dose was diclofenac 100 mg slow-release rather than the 150 mg used in the efficacy literature, and the trial ran 28 days in a disease treated for decades.

What this does not prove. Meeting one endpoint in one population does not carry to other goals or other people.

The limits of this study, and where it came from

Main limit. The comparator, piroxicam, was later assigned a pooled observational upper gastrointestinal complication relative risk of 7.43 — the second highest of any NSAID examined — so beating it is a weak benchmark. Efficacy was equivalent, and the trial ran 28 days.

How far it carries. This study is recorded from the curated record, not from the registry match.

What this does not prove. A study that did not show an effect does not show that no effect exists anywhere.

The limits of this study, and where it came from

Main limit. These are observational data and cannot exclude confounding by indication — meloxicam may be preferentially prescribed to patients already thought to be at gastrointestinal risk, which would bias against it. The sample-size field records the number of pooled studies, not participants. They remain the only hard-endpoint comparison across these molecules.

How close this is to real life

The top step is something a person would feel or care about. The bottom is a guess from software. Filled steps are where evidence exists for this substance.

  1. Living longer, or avoiding a major event No evidence recorded. Death, a heart attack, a stroke, a hospital stay.No registered study measures this.
  2. What a body can do day to day No evidence recorded. Walking, dressing, breathing, recovering.No registered study measures this.
  3. Measured performance No evidence recorded. How much was lifted, how far was run, how fast.No registered study measures this.
  4. Symptoms and quality of life Evidence recorded. Pain, tiredness, mood, sleep, as the person rated it.6 registered measures of this kind.
  5. A number that stands in for health Evidence recorded. Cholesterol, blood sugar, bone density. A stand-in, not the thing itself.4 registered measures of this kind.
  6. A step measured inside a person Evidence recorded. Something measured in human tissue or human cells.A human record sits on the stored organism ladder.
  7. Animals Evidence recorded. Mice, rats, dogs. Useful for ideas, not proof about people.Stored records in Mouse, Rat, Dog. A result in animals says what to test next. It does not say what happens in people.
  8. Cells in a dish Evidence recorded. Cells or chemistry on a bench, far from a whole body.Stored mechanism abstracts describe steps measured in cells or tissue.
  9. A guess from software No evidence recorded. Nobody measured it. RNAWiki never publishes one as a finding.RNAWiki stores no prediction for this record. Software can suggest a link. RNAWiki does not publish one as a finding.

Higher on these steps means closer to something a person would feel. It does not mean better done.

The path through the body

From what a person takes to what changes. A solid line is a step measured in people. A dashed line is a step nobody has measured that way.

Where a source records it acting

  • Joints: Concentrations in synovial fluid after a single oral dose range from 40% to 50% of those in plasma

    US prescribing information · 06a401f0-4380-4081-86ed-a309a25abf6b · read 2026-08-27

  1. Start

    Meloxicam

    What a person takes: Oral tablets at 7.5 and 15 mg, capsules, an oral suspension, a low-dose submicron capsule formulation and an orally disintegrating tablet; also an intravenous formulation. Taken once daily.

    The measurement behind this step

    Absolute bioavailability 89% against intravenous dosing, with dose-proportional pharmacokinetics from 7.5 to 15 mg orally. Absorption is slow: peak concentration at four to five hours, described in the label as prolonged, with a second peak at 12 to 14 hours attributed to biliary recycling and steady state reached by day five. Elimination half-life about 20 hours. A high-fat meal raises capsule peak concentration by about 22% without changing total exposure; the suspension is unaffected.

  2. Getting in

    One substitution away from piroxicam

    Meloxicam is chemically an oxicam, the same family as piroxicam. The difference is a single ring swapped at one position — and that swap is the whole basis of the claim that it is gentler.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    A 4-hydroxy-2-methyl-2H-1,2-benzothiazine-3-carboxamide 1,1-dioxide carrying 2-amino-5-methylthiazole where piroxicam carries 2-aminopyridine. Piroxicam’s pooled observational upper gastrointestinal relative risk is 7.43 (5.19 to 10.63); meloxicam’s is 3.47 (2.19 to 5.50). Better, and not in the range of celecoxib at 1.45.

  3. Reaching the cell

    Absorbed slowly, and then recycled

    It takes four to five hours to reach peak blood levels, and a second smaller peak arrives around twelve hours later because the liver sends it out in bile and the gut absorbs it again.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Absolute bioavailability 89%. Time to peak four to five hours at 7.5 mg fasted, described in the label as prolonged absorption. A second concentration peak occurs at 12 to 14 hours post-dose, attributed to biliary recycling. Steady state by day five; elimination half-life about 20 hours.

  4. What it acts on

    It blocks both enzymes — with a lean, at low concentrations

    Laboratory work shows meloxicam prefers the inflammation enzyme when the concentration is low. That preference weakens as concentration rises, and the licensed dose range doubles.

    Measured in animals. A result in animals says what to test next. It does not say what happens in people.

    The measurement behind this step

    Whole-blood COX-2 preference is real in vitro and concentration-dependent. The label makes no selectivity claim, stating only that the mechanism involves inhibition of cyclooxygenase COX-1 and COX-2 — the identical wording used for ibuprofen and naproxen. Pharmacokinetics are dose-proportional from 7.5 mg to 15 mg, so a doubled dose is a doubled concentration.

  5. The change it makes

    Prostaglandin falls and arthritis pain falls with it

    Once steady levels are reached, a single daily tablet keeps inflammatory messenger production down around the clock. That is what the drug is licensed for and what it does well.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    The label states that prostaglandins sensitise afferent nerves and potentiate the action of bradykinin in inducing pain, and are mediators of inflammation, and that meloxicam’s mode of action may be due to a decrease of prostaglandins in peripheral tissues. Licensed for osteoarthritis, rheumatoid arthritis and juvenile rheumatoid arthritis at 60 kg or above.

  6. What that does for a person

    And the stomach and kidney get no time off

    A twenty-hour half-life means the protective prostaglandins in the stomach lining and the kidney are suppressed continuously rather than in pulses, which is the likely reason a "preferential" drug ends up with diclofenac-range bleeding numbers.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Pooled observational upper gastrointestinal complication relative risk 3.47 (2.19 to 5.50) against diclofenac 3.34 (2.79 to 3.99), ibuprofen 1.84 (1.54 to 2.20) and celecoxib 1.45 (1.17 to 1.81). Acute myocardial infarction relative risk 1.25 (1.04 to 1.49), above ibuprofen 1.14 and celecoxib 1.12.

  7. What that does for a person

    What was measured, and what the label will not say

    Measured: fewer episodes of indigestion over 28 days than diclofenac or piroxicam, and slightly worse pain relief than diclofenac. Not stated in the label: any COX-2 selectivity, and any indication for acute pain.

    Measured in people. Written by a person from the study named beside the step. Not signed off as a reviewed claim.

    The measurement behind this step

    MELISSA: gastrointestinal adverse events 13% against 19% (P<0.001) but hard ulcer complications 5 against 7, not significant; efficacy consistently favoured diclofenac and more patients discontinued meloxicam for lack of efficacy (P<0.01). SELECT: adverse events 22.5% against 27.9% against piroxicam. Both trials ran 28 days.

No suggested links are held for this record, so nothing is hidden from this path.

What it would be like to takeRead from sources, not yet reviewed

Felt, measured, or meaningful

Three different things that get called the same word. Registered studies measured all three, and mixing them is how a blood test becomes a health claim.

Felt

Things a person could notice without a test.

  • pain intensity difference at end of study
  • spontaneous pharyngeal pain
  • pharyngeal pain on deglutition
  • summed pain intensity difference over the first 24 hours
  • pain
  • post operative pain

Measured

Things only a test, a scale or a device shows.

  • cmax maximum observed concentration
  • time to maximum concentration
  • time to reach maximum plasma concentration
  • maximum measured concentration of the analyte in plasma

Meaningful

Things that change how a life goes, not only a number.

No registered study measured anything of this kind.

A registered study says what someone planned to measure. It does not say what they found. A number moving is not the same as a life going better. The two are shown apart here.

Felt, but not shown to help. A person notices a change. No study showed it leads anywhere good.

Measured, but not felt. A number moves. The person notices nothing. Both can be true.

Measured, but not shown to matter. A number moves in the good direction. Nobody showed that lives went better.

Matters, but takes years. The result that counts may take longer than anyone would keep watching.

Names that fit none of the three (30)

  • efficacy
  • bioequivalence on cmax and auc parameters

How long anything takes

Nine different lengths of time that get confused with each other. None of them is worked out from another.

  1. Before anything is noticed. RNAWiki does not store this separately, and never works it out from another figure on this page.

  2. Before a test result moves. RNAWiki does not store this separately, and never works it out from another figure on this page.

  3. Before performance moves. RNAWiki does not store this separately, and never works it out from another figure on this page.

  4. How long the result was watched. No finished study window is recorded for a study that tested this substance.

  5. How long people took it. How long people actually took it is not stored. The study window is not the same thing.

  6. How long people were followed. Follow-up length is not stored separately. It is never read off the study window, which would be a different thing.

  7. How fast the body clears it. 15 hours to 20 hours hours

    Read from the label, which states: “The mean elimination half-life (t 1/2 ) ranges from 15 hours to 20 hours.”

  8. How long effects linger. RNAWiki does not store this separately, and never works it out from another figure on this page.

  9. Beyond the studies. Nothing is recorded about the long term.

    The longest finished study sets the edge of what anyone measured.

A study window is not how long people took it, and neither is how long they were followed. Where RNAWiki holds only one of the three, it shows one.

What is missing or unclearRead from sources, not yet reviewed

Were people like you studied?

RNAWiki cannot tell whether a study fits you. It can show who was in it, and where the result stops carrying.

Who was studied

People similar to this profile were included.

  • Adults with osteoarthritis or rheumatoid arthritis, and children with juvenile rheumatoid arthritis weighing at least 60 kg. Contraindicated in the setting of coronary artery bypass graft surgery and after aspirin- or NSAID-triggered asthma or urticaria.

Where the result stopped carrying

  • Hard ulcer complications in MELISSA were 5 against 7 and explicitly not statistically significant
  • Efficacy in MELISSA consistently favoured diclofenac, and significantly more patients quit meloxicam for lack of efficacy
  • Myocardial infarction risk is significantly raised where ibuprofen’s and celecoxib’s did not reach significance
  • The comparator in SELECT, piroxicam, was subsequently found to have the second-worst gastrointestinal profile of any NSAID studied
  • No trial has compared meloxicam with celecoxib on gastrointestinal outcomes at both licensed meloxicam doses
  • This is a scope explorer, not a diagnosis engine.
  • It shows who was studied so you can see whether people similar to you were included.

What it would be like to takeRead from sources, not yet reviewed

Why it might seem to do nothing

A real effect and a noticed effect are different things. These are the recorded reasons the two come apart.

It was studied for a different goal

The studies measured something else entirely.

On this record: Some registered studies measured things that match no goal on this page.

It was studied in different people

The people in the studies were not much like the reader.

On this record: Which groups were under-represented in the studies has not been recorded for this substance. Pregnancy, breastfeeding, children, older adults, and people with liver or kidney conditions are commonly excluded from trials; nothing here says whether they were.

The evidence may simply be wrong

Small early studies often do not hold up.

On this record: RNAWiki has not yet published a reviewed conclusion for this use.

Other reasons RNAWiki checked and found nothing for (10)
A different form was studied
The studied form is not the form on the shelf. Nothing in this record points to this reason.
There was nothing to correct
Where a level is already normal, topping it up may change nothing. Nothing in this record points to this reason.
Something else had to happen too
In the studies it was paired with training, a diet or another treatment. Nothing in this record points to this reason.
The change is too small to feel
A real change can still sit below what a person notices. Nothing in this record points to this reason.
Day-to-day swing hides it
Sleep, food, stress and time of day move most numbers more than this would. Nothing in this record points to this reason.
Not enough time yet
The studies ran longer than the person has waited. Nothing in this record points to this reason.
It was not taken as studied
Missed days change the result, and studies count them. Nothing in this record points to this reason.
Something else changed at the same time
Two changes at once cannot be told apart afterwards. Nothing in this record points to this reason.
The product may not be what it says
Contents of a sold product are not always what the label states. Nothing in this record points to this reason.
No recorded reason
RNAWiki has nothing stored that would explain it. Nothing in this record points to this reason.

None of these is a reason to take more. Taking more is not a step this page ever suggests.

Sorted by where each line came from. A regulator's label and a report somebody sent in are not the same kind of fact.

Worth asking a clinician aboutWritten into the record from the studies named on this page

Boxed warning for cardiovascular thrombotic events including fatal myocardial infarction and stroke, and for gastrointestinal bleeding, ulceration and perforation which can occur at any time and without warning symptoms. Contraindicated in the setting of coronary artery bypass graft surgery and after asthma, urticaria or other allergic-type reactions to aspirin or other NSAIDs. The long half-life means gastric, renal and platelet effects are sustained rather than intermittent, and exposure varies several-fold with age, sex, renal function and hepatic function at the same nominal dose.

Nobody counted how many people took this and were fine, so this cannot be turned into a rate.

What you could measure

This one is decided with a clinician, so this section holds questions to ask rather than a plan to run.

Self-experiment planning is not offered for a prescription or clinician-supervised medicine. The questions below are for a clinician or pharmacist.

Questions worth asking

  • Which of the trials of Meloxicam studied people like me?
  • What was measured, and for how long?
  • Was the result a laboratory value or a health outcome?
  • What would we watch for, and when would we stop?

The COX-2 selectivity claim is not in the label
In plain words
Meloxicam is almost always described as a COX-2 preferential anti-inflammatory, which is why people believe it is gentler than ibuprofen. Its United States prescribing information says only that its mechanism involves inhibition of COX-1 and COX-2, with no selectivity claim of any kind.
What was measured
That meloxicam is a selective or preferential COX-2 inhibitor in the clinically meaningful sense, and therefore gastrointestinally safer — an in vitro property extrapolated to patients, absent from the label, and contradicted by the observational hard-endpoint data
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
Section 12.1 of the meloxicam label reads: "Meloxicam has analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of meloxicam, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2)." It is word-for-word the same paragraph the label carries for ibuprofen and for naproxen. The laboratory literature on meloxicam’s COX-2 preference is genuine — whole-blood assays do show a ratio favouring COX-2 at lower concentrations — but it is concentration-dependent, and the licensed dose range spans a factor of two, from 7.5 mg to 15 mg. The comparison that would settle it, meloxicam against celecoxib on gastrointestinal outcomes at both doses, has never been run. What is on record instead is observational: in the pooled analysis of 28 observational studies, meloxicam’s upper gastrointestinal complication relative risk was 3.47 (95% CI 2.19 to 5.50), against celecoxib’s 1.45 (1.17 to 1.81) and ibuprofen’s 1.84 (1.54 to 2.20).

On hard gastrointestinal endpoints it sits with diclofenac, not with celecoxib
In plain words
The reason to choose meloxicam is usually the stomach. In the largest pooled analysis of observational studies, meloxicam’s risk of serious upper gastrointestinal complications was 3.47 times that of non-use — nearly double ibuprofen’s and more than double celecoxib’s.
What was measured
Pooled adjusted relative risk of upper gastrointestinal complications against non-use, by individual NSAID
Effect estimate
No reviewed effect estimate exists for this record.
Limits
This entry records a failure.
From the source
The SOS project meta-analysis pooled 28 cohort and case-control studies providing adjusted estimates for upper gastrointestinal complications against non-use of NSAIDs. Pooled relative risks ranged from 1.43 for aceclofenac to 18.45 for azapropazone. Below 2: aceclofenac, celecoxib 1.45 (95% CI 1.17 to 1.81) and ibuprofen 1.84 (1.54 to 2.20). Between 2 and 4: rofecoxib 2.32, sulindac 2.89, diclofenac 3.34 (2.79 to 3.99), meloxicam 3.47 (2.19 to 5.50), nimesulide 3.83 and ketoprofen 3.92. Between 4 and 5: tenoxicam, naproxen 4.10 (3.22 to 5.23), indometacin 4.14 and diflunisal. Above 5: piroxicam 7.43, ketorolac 11.50 and azapropazone. High daily doses carried risks two to three times those of low daily doses. So meloxicam is better than the older oxicams it descends from — piroxicam is at 7.43 — and worse than the two drugs it is most often chosen over. These are observational data with the confounding that implies, and they are the only hard-endpoint data comparing these molecules directly.

MELISSA and SELECT measured dyspepsia over 28 days, and meloxicam lost on efficacy
In plain words
The two trials that made meloxicam’s reputation enrolled nearly eighteen thousand people — for twenty-eight days, measuring reported side effects rather than bleeds. Serious ulcer complications were not significantly different, and in one trial pain relief consistently favoured the comparator, with significantly more people quitting meloxicam because it was not working.
What was measured
Gastrointestinal adverse event rates, hard ulcer complication counts, efficacy on visual analogue scales and withdrawal for lack of efficacy over 28 days
Effect estimate

From the source
MELISSA randomised 9,323 osteoarthritis patients to meloxicam 7.5 mg or diclofenac slow-release 100 mg for 28 days. Gastrointestinal adverse events were 13% against 19% (P<0.001), driven by dyspepsia, nausea, abdominal pain and diarrhoea. Perforations, ulcers or bleeds were 5 on meloxicam against 7 on diclofenac — explicitly reported as not significant — though no endoscopically verified ulcer complication occurred on meloxicam against four on diclofenac, and hospitalisation was 5 patient-days against 121. The trial also reported that differences in efficacy on visual analogue scales consistently favoured diclofenac with 95% confidence intervals not crossing zero, and that significantly more patients discontinued meloxicam for lack of efficacy (80 of 4,635 against 49 of 4,688, P<0.01). SELECT randomised 8,656 patients to meloxicam 7.5 mg or piroxicam 20 mg for 28 days: adverse events 22.5% against 27.9% (P<0.001), gastrointestinal adverse events 10.3% against 15.4% (P<0.001), and perforations, ulcers or bleeds 7 against 16 (relative risk 1.4), with four complicated events all in the piroxicam arm. Three limits define what these trials can support: the endpoints are tolerability rather than complications, the duration is one month in a disease treated for decades, and the comparators are a diclofenac dose below its most-used one and piroxicam, which the observational data later placed at a relative risk of 7.43 — the second worst NSAID examined.

The oral label has no acute pain indication, and the pharmacokinetics say why
In plain words
Meloxicam is handed out constantly for a wrenched back or after a tooth extraction. Peak blood concentration comes four to five hours after the dose, steady state takes five days, and the label’s three indications are all chronic arthritis.
What was measured
Licensed indications, time to peak plasma concentration, time to steady state and elimination half-life

From the source
Section 1 of the meloxicam tablet label lists osteoarthritis, rheumatoid arthritis and pauciarticular or polyarticular course juvenile rheumatoid arthritis in patients weighing at least 60 kg. There is no acute pain indication, in contrast to celecoxib, ibuprofen, naproxen, diclofenac potassium and ketorolac, all of which carry one. Section 12.3 explains the pharmacology behind that: mean peak concentration is achieved within four to five hours of a 7.5 mg tablet under fasted conditions, which the label itself describes as indicating prolonged drug absorption; steady-state concentrations are reached by day five; the elimination half-life is about 20 hours; and a second concentration peak occurs around 12 to 14 hours post-dose, suggesting biliary recycling. A drug that peaks at four to five hours and stabilises on day five is a maintenance analgesic. Prescribing it for pain that needs to be gone within the hour is an extrapolation the label does not support and the pharmacokinetics contradict.

Myocardial infarction risk is significantly raised, above ibuprofen and celecoxib

Effect estimate

From the source
The SOS project meta-analysis of 25 publications covering 18 independent study populations reported random-effects relative risks for acute myocardial infarction against non-use: naproxen 1.06 (95% CI 0.94 to 1.20), celecoxib 1.12 (1.00 to 1.24), ibuprofen 1.14 (0.98 to 1.31), meloxicam 1.25 (1.04 to 1.49), rofecoxib 1.34 (1.22 to 1.48), diclofenac 1.38 (1.26 to 1.52), indometacin 1.40 (1.21 to 1.62), etodolac 1.55 (1.16 to 2.06) and etoricoxib 1.97 (1.35 to 2.89). Heterogeneity between studies was present. Except for naproxen, higher risk was generally associated with higher doses, and in patients with prior coronary heart disease, use of three months or less was already associated with increased risk. Meloxicam therefore sits above the two drugs it is most often preferred to on both axes at once — gastrointestinal complications and myocardial infarction — which is the opposite of the trade-off its reputation implies.

Exposure varies about five-fold between the populations that take it
In plain words
The same 15 mg tablet produces very different blood levels in a healthy young man, an elderly woman, someone with kidney failure and someone with liver disease — and the label’s own table shows the range.
What was measured
Peak concentration, time to peak and apparent clearance across healthy adults, elderly males and females, renal failure and hepatic insufficiency
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
The label’s pharmacokinetic table reports peak concentration on 15 mg meloxicam capsules of 2.3 µg/mL (CV 59%) in elderly males, 3.2 µg/mL (24%) in elderly females, 0.59 µg/mL (36%) in renal failure and 0.84 µg/mL (29%) in hepatic insufficiency, against 1.05 µg/mL (20%) for a 7.5 mg tablet in healthy male adults. Apparent clearance ranges from 5.1 mL/min in elderly females to 19 mL/min in renal failure. Time to peak stretches to 10 hours (CV 87%) in hepatic insufficiency. Absolute bioavailability is 89%. A high-fat breakfast raises peak concentration of the capsule by about 22% without changing total exposure. The practical consequence is that "7.5 mg" and "15 mg" describe the tablet, not the exposure, and the population in whom exposure is highest — elderly women — is also the population at highest baseline risk of the gastrointestinal and renal effects that exposure drives.

The older medicine-wide conclusion held in this record

Written for a clinical reader, and about the medicine as a whole rather than about one indication, population and set of trials. RNAWiki does not treat it as a programme conclusion and no reviewer has signed it off in that form. It is here word for word because it is what the record holds.

A long-half-life once-daily NSAID whose reputation for being a gentle, selective, fast-acting painkiller survives none of the three checks: its label claims no selectivity, its time to peak concentration is four to five hours with steady state on day five and no acute pain indication, and in pooled observational data its upper gastrointestinal complication risk is 3.47-fold — above ibuprofen at 1.84 and celecoxib at 1.45, and level with diclofenac.

What do 1995 spontaneous reports say about Meloxicam — and not say?


These are reports people sent to a regulator. They do not show the medicine caused the reaction. Nobody counted how many people took the medicine and reported nothing. The same event can be reported more than once, and many reports are incomplete. News coverage, lawsuits and new warnings change how often people report. A count is not a rate and not a risk.

Meloxicam appears in spontaneous reports to regulators. Across the 10 most-reported reaction terms, 1995 reaction mentions were counted: drug hypersensitivity 535; arthralgia 217; gastrointestinal haemorrhage 214; joint swelling 165. open-targets-adr · CHEMBL599 · 2026-06-24
