Egg albumin microspheres containing paracetamol for oral administration. II. In vivo investigation

Abstract

Egg albumin microspheres containing paracetamol for oral administration were prepared and their in vivo characteristics evaluated. The egg albumin microspheres were able to improve the organoleptic characteristics of paracetamol formulations. The pharmacokinetic characteristics of three different formulations of paracetamol were evaluated in six volunteers. The formulations administered orally were: (1) Paracetamol granulated with lactose (reference), (2) Egg albumin microspheres and (3) Egg albumin microspheres coated with polymethacrylate.
