METHYLPHENIDATE MODIFIED RELEASE FORMULATIONS

Abstract

The present invention relates to therapeutic compositions and methods for the treatment of attention deficit disorder (ADD), or attention deficit hyperactivity disorder (ADHD). The present invention more particularly relates to a modified-release pharmaceutical formulation designed to improve the delivery and efficacy of central nervous system (CNS) stimulants. The composition consists of a drug-containing core with a CNS stimulant and pharmaceutically acceptable excipients. This core is coated with a sustained-release (SR) layer comprising one or more polymers selected from water-insoluble and water-insoluble pH-dependent polymers, and one or more pharmaceutically acceptable excipients which regulates the gradual release of the drug. Surrounding the SR layer is a delayed-release (DR) outer layer that controls the onset of drug release. This approach aims to enhance symptom control, reduce dosing frequency, and improve patient compliance in the treatment of ADD and ADHD.
