Effect of the Gastrointestinal Prokinetic Agent Erythromycin on the Pharmacokinetics of Pregabalin Controlled-Release in Healthy Individuals: A Phase I, Randomized Crossover Trial

Background and Objectives The controlled-release (CR) formulation of pregabalin is designed to remain in the stomach for a prolonged period while slowly releasing pregabalin for absorption in the small intestine. This study evaluated the effect of the gastrointestinal prokinetic agent, erythromycin, on the pharmacokinetics of a single dose of pregabalin CR 330 mg administered following an evening meal and the safety and tolerability of a single dose of pregabalin CR 330 mg when administered with and without multiple doses of erythromycin 500 mg.
