Randomized Controlled Trial Comparative Study Clinical TrialBioequivalence study comparing a new paracetamol solution for injection and propacetamol after single intravenous infusion in healthy subjects.
A new, ready-to-use solution for injection of paracetamol (Perfalgan 10 mg/ml) without previous reconstitution has been developed. The aim of the study was to determine the serum concentration profiles of paracetamol after 15 min infusion of Perfalgan 0.5 g and 1 g doses and to demonstrate the bioequivalence between Perfalgan 1 g dose and a marketed reference formulation for injection, propacetamol 2 g (Pro-Dafalgan 2 g) equivalent to 1 g of paracetamol. The secondary objective was to evaluate local tolerance, and clinical and biological safety. ⋯ After administration of paracetamol solution for injection 0.5 g and 1 g, the pharmacokinetics of paracetamol is linear. All results indicate that 1 g of paracetamol administered as Perfalgan 10 mg/ml is bioequivalent to propacetamol 2 g with a better local safety.
