Cinarizine (CINNARIZINE)

Phase 2 active Small molecule

Cinarizine (generic name: CINNARIZINE) is a cinnarizine drug. It is currently in Phase 2 development for Motion sickness, Nausea, Vertigo.

Cinarizine works by blocking histamine receptors in the brain, which helps to reduce symptoms of motion sickness and vertigo.

Cinarizine, also known as CINNARIZINE, is a small molecule drug that targets the histamine H1 receptor. It is used to treat motion sickness, nausea, and vertigo. The commercial status of Cinarizine is unknown, but it is likely off-patent. As a histamine H1 receptor antagonist, Cinarizine works by blocking the action of histamine, a chemical that can cause blood vessels to dilate and lead to symptoms of motion sickness and vertigo. This makes it easier for patients to manage their symptoms.

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
NMPA CN 2033–2037 +2.3 yr
MFDS KR 2032–2036 +1.4 yr
CDSCO IN 2032–2037 +1.8 yr
ANVISA BR 2033–2037 +2.3 yr

Hover any row for the lag rationale. Lag estimates are reduced when the drug has FDA Breakthrough or EMA PRIME designation (sponsors file globally in parallel).

Mechanism of action

Imagine your brain is like a busy airport, and histamine is like a message that tells the 'air traffic control' to let more planes in. When you're on a boat or a car, your body gets confused and sends out too many of these messages, making you feel sick. Cinarizine is like a 'blocker' that stops these messages from getting through, helping you feel better.
