Arestal (LOPERAMIDE OXIDE)

Phase 2 active Small molecule

Arestal (generic name: LOPERAMIDE OXIDE) is a loperamide oxide drug. It is currently in Phase 2 development.

Arestal works by binding to opioid receptors in the gut to slow down bowel movements.

Arestal, also known as Loperamide Oxide, is a small molecule drug of the loperamide class. Its mechanism of action and approved indications are not well-documented. As a result, there is limited information available on its commercial status, safety considerations, or pharmacokinetic properties. Further research is needed to fully understand Arestal's characteristics and potential applications. Its development history is also unclear.

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

Mechanism of action

Imagine your gut is like a highway, and Arestal is like a traffic cop that slows down the traffic. By doing so, it helps to reduce diarrhea and other symptoms associated with irritable bowel syndrome (IBS). This is achieved by reducing the movement of food through the digestive system.
