Pharmaceutical capsule compositions containing the active compound (2R)-2-[[(4-chlorophenyl)sulfonyl][[2-fluoro-4-(1,2,4-oxadiazol-3-yl)phenyl]methyl]amino]-5,5,5-trifluoropentanamide, and polyethylene glycol (PEG), Vitamin E polyethylene glycol succinate, polyvinylpryrrolidone (PVP) or copovidone (PVP-Polyvinyl acetate), with or without citric acid, are provided.

Bioavailable capsule compositions of amorphous alpha-(N-sulfonamido)acetamide compound

A drug formulation in the form of a dry powder is provided which when mixed with water forms a palatable oral suspension substantially free of bitter taste, the dry powder being formed of a drug, preferably des-quinolone, which in solution has a bitter taste, and a pH modifying agent which is preferably an alkaline material such as L-arginine, where upon mixing the dry-powder in water causes the drug to have reduced solubility or precipitate in-situ to form a palatable oral suspension essentially free of bitter taste. An oral suspension, methods for making same and a method for masking the bitter taste of drugs employing one or more pH modifying agents are also provided.

Palatable oral suspension and method

A high drug load spheronized beadlet is provided wherein said beadlet comprises about 80% to 100% by weight of an acid labile medicament, preferably didanosine, about 0% to about 10% by weight of a disintegrant, and about 0% to about 10% by weight of a binder selected from the group consisting of sodium carboxymethylcellulose, hydroxypropylmethylcellulose, potassium alginate, and partially pregelatinized corn starch. A high drug load pharmaceutical composition, comprising the beadlet, with an enteric coating disposed thereon, is also provided.

High drug load acid labile pharmaceutical composition

A high drug load enteric coated pharmaceutical composition is provided which includes a core in the form of a tablet and which is comprised of a medicament which is sensitive to a low pH environment of less than 3, such as ddl, and having an enteric coating formed of methacrylic acid copolymer and a plasticizer. The tablets may be of varying sizes and may be orally ingested individually or a plurality of tablets sufficient to attain a desired dosage may be encapsulated in a dissolvable capsule. The tablets have excellent resistance to disintegration at pH less than 3 but have excellent drug release properties at pH greater than 4.5. A novel method of making said pharmaceutical composition is also disclosed.

Enteric coated pharmaceutical tablet and method of manufacturing

A pharmaceutical composition is provided which is useful for cholesterol lowering and reducing the risk of a myocardial infarction, which includes a statin, such as pravastatin, lovastatin, simvastatin, atorvastatin, cerivastatin or fluvastatin, in combination with aspirin, in a manner to minimize interaction of aspirin with the statin and minimize side effects of aspirin. A method for lowering cholesterol and reducing risk of a myocardial infarction employing such composition is also provided.

Pharmaceutical composition containing a combination of a statin and aspirin and method

A high drug load enteric coated pharmaceutical composition is provided which includes a core comprised of a medicament which is sensitive to a low pH environment of less than 3, such as ddl, which composition is preferably in the form of beadlets having an enteric coating formed of methacrylic acid copolymer, plasticizer and an additional coat comprising an anti-adherent. The so-called beadlets have excellent resistance to disintegration at pH less than 3 but have excellent drug release properties at pH greater than 4.5. A novel method of making said pharmaceutical composition is also disclosed.

Method for the preparation of an enteric coated high drug load pharmaceutical composition

An improved cholesterol-lowering tablet is manufactured by blending tablet grade cholestyramine with an appropriate amount of lubricant and directly compressing into elongated tablets having a specified thickness. These inner tablets are successfully film coated using aqueous film-coating processes without tablet preheating and by simultaneous spray-drying.

Cholesterol-lowering tablets

Improved oral dosage formulations for acid-labile dideoxy purine nucleoside derivatives such as ddA, ddI, and ddG, have been developed by incorporating selected water-insoluble buffering systems in the formulation. These novel formulations provide reduced mass dosage units in the form of convenient, palatable chewable/dispersible tablets or a dry powder sachet. The reduced mass requirement, necessary to allow tablets of reasonable size, was achieved in part by an unexpected 20 to 25% increase in drug bioavailability resulting from use of the selected buffering systems comprised of an insoluble magnesium antacid agent and either dihydroxyaluminum sodium carbonate or calcium carbonate.
