Patent number: 6960356Abstract: A pharmaceutical composition in the form of tablets or capsules provides a combination of temporal and spatial control of drug delivery to a patient for effective therapeutic results. The pharmaceutical composition comprises a drug, a gas generating component, a swelling agent, a viscolyzing agent, and optionally a gel forming polymer. The swelling agent belongs to a class of compounds known as superdisintegrants (e.g., cross-linked polyvinylpyrrolidone or sodium carboxymethylcellulose). The viscolyzing agent initially and the gel forming polymer thereafter form a hydrated gel matrix which entraps the gas, causing the tablet or capsule to be retained in the stomach or upper part of the small intestine (spatial control). At the same time, the hydrated gel matrix creates a tortuous diffusion path for the drug resulting in sustained release of the drug (temporal control). A preferred once daily ciprofloxacin formulation comprises 69.9% profloxacin base, 0.34% sodium alginate, 1.103% xanthan gum, 13.Type: GrantFiled: July 2, 1999Date of Patent: November 1, 2005Assignee: Ranbaxy Laboratories LimitedInventors: Naresh Talwar, Himadri Sen, John N. Staniforth
