Phase 2 active Small molecule ✓ Verified May 2026

Rimazolium (generic name: RIMAZOLIUM METILSULFATE) is a rimazolium drug. It is currently in Phase 2 development.

Rimazolium is thought to work by interacting with a specific biological target, but its exact mechanism is unclear.

Rimazolium is a small molecule. It is also known by various synonyms, including METILSULFATE DE RIMAZOLIUM, METILSULFATO DE RIMAZOLIO, and RIMAZOLIUM METHYLSULFATE.

Likelihood of approval

15.3% 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).

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
NMPA	CN	2033–2037	+2.3 yr

Mechanism of action

Imagine your body's cells are like locks, and rimazolium is a key that fits into one of those locks. When it binds to the lock, it can affect how the cell works, but we don't know exactly how it does that yet. More research is needed to understand how rimazolium interacts with cells and tissues.
