Rapamycin (Sirolimus) vs SSRIs (Sertraline, Escitalopram)
Both are used for stress & anxiety. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Rapamycin (Sirolimus) | SSRIs (Sertraline, Escitalopram) | |
|---|---|---|
| Human evidence | ★★★★★ | ★★★★★ |
| Legal status | Off-Label, FDA Approved | FDA Approved |
| How it works | Binds FKBP12 to inhibit mTOR complex 1 — flipping cells from growth to maintenance (autophagy, stress resistance, less senescence). What mTOR is and why dialling it down matters → the mTOR pathway. The compound-specific nuance is… | Block the serotonin transporter (SLC6A4), raising synaptic serotonin; downstream BDNF/neuroplasticity changes over weeks explain the delayed benefit. |
| In plain English | Rapamycin dials the "grow" switch (mTOR) down periodically, flipping cells into "clean and repair." It extends lifespan in every animal tested — the single most reliable longevity drug — but human data is still coming in. Taken weekly, not… | Keep serotonin in the synapse longer; over weeks this rewires mood circuits. First-line for depression/anxiety — real, evidence-based medicine. |
| Bottom line | The most compelling longevity drug we have; still needs human RCTs (PEARL, others ongoing). | Standard of care; the herbal options don't replace these for moderate-severe illness. |
| Availability | Prescription only | Available over the counter |
Which is better for stress & anxiety?
Both carry a comparable human-evidence rating (★★★★★). Choose on mechanism fit, side-effects, availability and cost rather than evidence strength alone — they work through different mechanisms.
