Ivermectin Solution Bioequivalence Study - With Food (Repeat)
The purpose of this study was to compare the pharmacokinetic and bioavailability profile (rate and amount of absorption into the bloodstream) of a test formulation of Ivermectin solution 1 mg/ml with a marketed reference formulation of Ivermectin 3 mg tablets when taken after a standard meal. The study is designed in accordance with the EU Note for Guidance on the Investigation of Bioavailability and Bioequivalence 2001.

Each subject will receive single doses of (i) 22.5 ml ivermectin oral solution (22.5 mg) and (ii) 10 x 3 mg tablets of ivermectin (30 mg) in 2 separate dosing periods. Doses will be administered 20 minutes after a standard breakfast.

Ivermectin is an antiparasitic medicine (i.e. a medicine used to eliminate parasitic worms) for oral administration, and is approved in the US and some other countries in a tablet form. A new liquid formulation of ivermectin has been developed to facilitate dosing. This is a single dose, randomised, crossover study in healthy adult male and female volunteers, with doses taken 20 minutes after a standard breakfast. Doses will separated by washout period of at least 14 days. Twenty-one blood samples will be taken from each volunteer over 144 hours in each period. Concentrations of Ivermectin in plasma will be measured using a validated chromatographic assay (LC-MS/MS). Standard pharmacokinetic parameters will be obtained and bioequivalence on the basis of rate and extent of drug absorption will be assessed.
