Abstract: The present invention relates to sustained release pharmaceutical compositions of donepezil or pharmaceutically acceptable salts thereof. The compositions of the invention are stable and provide sustained therapeutically effective plasma levels over a twenty four hour period with reduced incidences of cholinergic side effects. The invention also relates to process of making such compositions.

Abstract: The present invention relates to dispersible tablets of cephalexin and a process for their preparation.

Abstract: The technical field of the present invention relates to uncoated, taste masked sumatriptan tablets for oral administration and processes for their preparation. It also relates to wax polished sumatriptan tablets and processes for their preparation.

Abstract: The technical field of the invention relates to pharmaceutical compositions of 9-(1,3-dihydroxy-2-propoxymethyl) guanine (ganciclovir) that are stable and contain more than 1% water content. One pharmaceutical composition includes ganciclovir having more than about 1% water content, and one or more pharmaceutically acceptable excipients. The ganciclovir retains at least about 97% of its initial purity after one month, at least about 96% of its initial purity after two months, and at least about 95% of its initial purity after three months when stored at 40° C. and 75% RH. In particular, the water content may be between about 2% and about 6%.

Abstract: The invention relates to robust formulations of valacyclovir hydrochloride tablets. A robust tablet includes a hydrated form of valacyclovir hydrochloride having a water of hydration content of more than approximately 3% w/w and a particle size of less than approximately 355 ?m.

Abstract: The technical field of the present invention relates to stable aqueous solution of risperidone for oral administration; and process for preparation thereof.

Abstract: The present invention is generally directed to methods for preparing stable gabapentin tablets by wet granulation. A wet granulation method for preparing gabapentin tablets includes forming a mixture by dry mixing of a first portion of a binder with the gabapentin, one or more excipients, or a combination of the gabapentin and the one or more excipients; and adding a second portion of the binder to the mixture, wherein the second portion of the binder is in the form of a solution or dispersion.

Abstract: The present invention generally relates to controlled release dosage forms which provide immediate release and sustained release of nitrofurantoin, and processes for their preparation. The controlled release dosage form includes a sustained release portion and an immediate release portion. The sustained release portion includes nitrofurantoin and one or more pH dependent hydrophilic polymers. The immediate release portion includes nitrofurantoin.
