Abstract: The compositions of the present invention comprise a therapeutically effective amount of particles consisting of diphenhydramine or pharmaceutically acceptable salts thereof, optionally in combination with another drug such as pseudoephedrine, or phenylephrine and hydrocodone, in combination with rapidly-dispersing microgranules comprising a disintegrant and a sugar alcohol and/or a saccharide. These compositions are useful in treating the symptoms of one or more diseases or conditions in which diphenhydramine (alone or in combination with one or two other drugs) is a therapeutically effective, e.g. allergic rhinitis, sinusitis, upper respiratory tract infections, motion sickness, Parkinson's disease, insomnia, the common cold, and nighttime pain management, particularly for subjects or patients with dysphagia, and people ‘on the move’.

Abstract: A unit dosage form, such as a capsule or the like for delivering drugs into the body in a circadian release fashion, is comprising of one or more populations of propranolol-containing particles (beads, pellets, granules, etc.). Each bead population exhibits a pre-designed rapid or sustained release profile with or without a predetermined lag time of 3 to 5 hours. Such a circadian rhythm release cardiovascular drug delivery system is designed to provide a plasma concentration-time profile, which varies according to physiological need during the day, i.e., mimicking the circadian rhythm and severity/manifestation of a cardiovascular disease, predicted based on pharmaco-kinetic and pharmaco-dynamic considerations and in vitro/in vivo correlations.

Abstract: A pharmaceutical dosage form such as a capsule capable of delivering therapeutic agents into the body in a time-controlled or position-controlled pulsatile release fashion, is composed of a multitude of multicoated particulates (beads, pellets, granules, etc.) made of one or more populations of beads. Each of these beads except an immediate release bead has at least two coated membrane barriers. One of the membrane barriers is composed of an enteric polymer while the second membrane barrier is composed of a mixture of water insoluble polymer and an enteric polymer. The composition and the thickness of the polymeric membrane barriers determine the lag time and duration of drug release from each of the bead populations. Optionally, an organic acid containing intermediate membrane may be applied for further modifying the lag time and/or the duration of drug release.

Each bead population exhibits a pre-designed rapid or sustained release profile with or without a predetermined lag time of 3 to 5 hours. Such a circadian rhythm release drug delivery system is designed to provide a plasma concentration-time profile, which varies according to physiological need at different times during the dosing period, i.e., mimicking the circadian rhythm and severity/manifestation of gastric acid secretion (and/or midnight gerd), predicted based on pharmaco-kinetic and pharmaco-dynamic considerations and in vitro/in vivo correlations.
