Latest Patents

Langridge holds a patent for a long-acting calcium channel blocker composition. This patent describes an improved sustained release pharmaceutical composition for dihydropyridine calcium channel blockers. The composition features intimately admixed calcium channel blockers and a pH-dependent binder, formed into essentially spherically shaped non-rugose particles of up to 1.2 mm in diameter. A coating is applied to these particles to ensure a slow, sustained release of a therapeutically effective amount of the calcium channel blocker over a period of at least 24 hours. This advancement allows for once-daily administration, improving patient compliance and treatment outcomes.
