Chemical Structure System Components and Performance: Verapamil Hydrochloride Extended-release Capsules (PM) uses the proprietary CODAS ® (Chronotherapeutic Oral Drug Absorption System) technology, which is designed for bedtime dosing, incorporating a 4 to 5-hour delay in drug delivery. The controlled-onset delivery system results in a maximum plasma concentration (C max ) of verapamil in the morning hours. These pellet filled capsules provide for extended-release of the drug in the gastrointestinal tract. The Verapamil Hydrochloride Extended-release Capsules (PM) formulation has been designed to initiate the release of verapamil 4-5 hours after ingestion. This delay is introduced by the level of non-enteric release-controlling polymer applied to drug loaded beads. The release-controlling polymer is a combination of water soluble and water insoluble polymers. As water from the gastrointestinal tract comes into contact with the polymer coated beads, the water soluble polymer slowly dissolves and the drug diffuses through the resulting pores in the coating. The water insoluble polymer continues to act as a barrier, maintaining the controlled release of the drug. The rate of release is essentially independent of pH, posture and food. Multiparticulate systems such as Verapamil Hydrochloride Extended-release Capsules (PM) have been shown to be independent of gastrointestinal motility.
