Frequently asked questions about New Paracetamol

What is New Paracetamol used for?

New Paracetamol is an investigational small molecule being developed for the treatment of pain. It is currently in Phase 1 clinical development, meaning it has not yet been approved by regulatory authorities and is still being studied for safety and efficacy in clinical trials.

Who makes New Paracetamol?

New Paracetamol is being developed by Haleon plc, a consumer healthcare company listed on the London Stock Exchange under the ticker HLN. The company is conducting clinical trials to evaluate this investigational pain medication.

What phase is New Paracetamol in?

New Paracetamol is in Phase 1 clinical development. It is an investigational drug, not yet approved by the FDA or other regulatory agencies. The drug is being studied in healthy volunteers to assess its bioequivalence and safety profile.

What clinical trials is New Paracetamol in?

New Paracetamol has one completed Phase 1 clinical trial, NCT05022810, which was a bioequivalence study comparing a new paracetamol oral suspension 24mg/ml to the marketed Panadol Baby and Infant 24mg/ml suspension. The trial enrolled 61 healthy adult subjects in Czechia.

Is New Paracetamol the same as Panadol?

New Paracetamol is a new formulation of paracetamol, the active ingredient in Panadol. The Phase 1 trial NCT05022810 compared New Paracetamol oral suspension to the marketed Panadol Baby and Infant suspension to assess bioequivalence, meaning the new formulation is intended to deliver the same drug in a comparable manner.
