Phase 2 active Small molecule ✓ Verified May 2026

Pragman (generic name: TOLPROPAMINE) is a tolpropamine drug. It is currently in Phase 2 development.

Tolpropamine is thought to work by modulating the activity of certain neurotransmitters in the brain.

Tolpropamine is a small molecule. It has synonyms including TOLPROPAMINA and TOLPROPAMINE.

Likelihood of approval

12.3% vs 15.3% industry baseline

If approved by FDA: likely 2031–2034

Steps remaining: Phase 3 → NDA/BLA submission

Confidence: Medium

Why this estimate

Baseline phase 2 → approval rate +15.3pp
Industry-wide phase 2 drugs reach approval ~15.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
CNS / neurology attrition -3.0pp
CNS drugs have historically high Phase 3 failure rates (notably in Alzheimer disease + major depression).

Predicted approval windows by jurisdiction (conditional on FDA approval)

Regulator	Country	Likely year	Lag vs FDA
FDA	US	2031–2034	—
EMA	EU	2032–2035	+0.7 yr
MHRA	GB	2032–2035	+0.7 yr
Health Canada	CA	2032–2036	+0.9 yr
TGA	AU	2032–2036	+1.2 yr
PMDA	JP	2032–2036	+1.5 yr

Mechanism of action

Imagine your brain is like a city with many different streets and intersections. Tolpropamine helps regulate the flow of chemical messengers, called neurotransmitters, that travel along these streets to communicate with different parts of the brain. By adjusting the activity of these neurotransmitters, tolpropamine may help alleviate certain symptoms or conditions.
