US Classification:

424471000, 514649000

Abstract:

A controlled-release, non-sedating antihistamine and decongestant composition which provides a 24-hour decongestant dissolution profile using standard ungranulated xanthan gum as the sole controlled-release agent and a process for preparing the same is provided. The pharmaceutical composition of the present invention typically includes: a compressed extended-release core comprising a pharmaceutically effective amount of decongestant, ungranulated xanthan gum, one or more binders, a flow agent, and a lubricant. An immediate-release coating composition is disposed on the core that typically includes a non-sedating antihistamine and at least one coating agent.

International Classification:

A61K 9/48

US Classification:

424452, 2491871, 425177

Abstract:

A caplet having press-fit gelatin capsule shell halves includes one or more dimples formed in one or both ends of the caplet shells, which significantly reduces the thickness of the gelatin which thereby dissolves more quickly, allowing the medicament to be rapidly released into the body's digestive system. In one embodiment of the invention, the closing pins used to press the conventional capsule shell halves onto a core include a raised projection for debossing the dimples. As holding blocks of a press-fit machine move to encapsulate a caplet, closing pins form compressed dimples in at least one or preferably both ends of the gelatin capsule shell as the shells are applied to the core.
