Abstract: An extended release acetaminophen composition comprises particles containing acetaminophen coated on sugar/starch seeds. The particles are present as a blend of both an immediate release and a controlled release form. The composition, when contained within a gelatin capsule and assayed in a USP Apparatus I rotating basket at 50 rpm in 900 mL of phosphate buffer at pH 5.8 and a temperature of 37° C., exhibits about 40 percent acetaminophen dissolution at one-half hour, about 55 percent acetaminophen dissolution at one hour, and substantially complete dissolution of acetaminophen at six hours. A process for treating a human patient with the extended release acetaminophen composition is also disclosed.

Abstract: A liquid pharmaceutical composition is contemplated that comprises a pharmaceutically effective amount of a bitter tasting drug dissolved or dispersed in an aqueous medium that is free of ethanol. That aqueous medium consists essentially of water, about 5 to about 30 weight percent polyvinylpyrrolidone, about 35 to about 55 weight percent of a C.sub.3 -C.sub.6 polyol, about 0.01 to about 0.5 weight percent ammonium glycyrrhizinate and one or more flavorants. The liquid composition is transparent and has a pleasant taste. The bitter tasting drugs claimed herein are vitamin and mineral preparations, trimethoprim, and guaifenesin.

Abstract: This invention is directed to an aqueous pharmaceutical composition with 1.25 mg to about 10 mg trimethoprim per mL (wt/vol) of solution and a compound of suitable acid strength to permit the dissolving of trimethoprim at the appropriate concentration, with the composition having a pH of less than 6.0. This composition is particularly useful for pediatric oral use.

Abstract: This invention is directed to pharmaceutical compositions of calcium polycarbophil (CPC) sprinkles. The CPC sprinkles contain very fine calcium polycarbophil powder, with smooth particles, and are processed with one or more excipients to produce a flowable, dispersible composition. For pediatric dosing, the CPC sprinkles are premixed with food and when placed in the mouth, its smooth and creamy consistency makes it easy to ingest without leaving a gritty mouthfeel.
