Abstract: The present invention is a method of achieving fast onset of pain relief for acute pain in a patient in need thereof comprising orally administering a unitary formulation (or oral dosage form) containing an effective analgesic amount of (a) oxycodone or a pharmaceutically acceptable salt thereof and (b) ibuprofen or a pharmaceutically acceptable salt thereof. Preferably, the unitary formulation contains (a) oxycodone or a pharmaceutically acceptable salt thereof and (b) ibuprofen or a pharmaceutically acceptable salt thereof at a weight ratio of from about 1:20 to about 1:100 and more preferably about 1:40 to about 1:80, based on the weights of molar equivalents of oxycodone hydrochloride and ibuprofen, respectively. Preferably, an amount of oxycodone and ibuprofen effective to provide partial or complete pain relief within 30 minutes is administered. More preferably, the amount is sufficient to provide partial or complete pain relief within 25 minutes.

Abstract: A method of treatment of a mammal, including humans, suffering from traumatic brain injury, which comprises administering to the sufferer a therapeutically effective amount of a butyrolactone derivative.

Abstract: A therapeutically active solid unit dosage form comprising a carrier base material combined with a therapeutically active medicament and shaped and compressed to a solid unit dosage form having a controlled and sustained release pattern upon administration, the carrier base material comprising a mixture of one or more nonionic cellulose ethers and an alkali metal carboxylate, wherein at least one of the cellulose ethers is hydroxypropylmethylcellulose having a number average molecular weight of at least 50,000.

Abstract: A therapeutically active solid unit dosage form having a controlled and prolonged release pattern upon administration, comprising a mixture of a high viscosity grade methylcellulose or hydroxypropylmethylcellulose, an alkali metal sulfate or sulfonate and a therapeutically active medicament.

Abstract: A carrier base material combined with a therapeutically active medicament and shaped and compressed to a solid unit dosage form having a controlled and prolonged release pattern upon administration, the carrier base material being a mixture of one or more nonionic cellulose ethers and an anionic surfactant, and wherein at least one of the cellulose ethers is methyl cellulose or hydroxypropylmethylcellulose having a number average molecular weight of at least 50,000.

Abstract: A carrier base material combined with a therapeutically active medicament and shaped and compressed to a solid unit dosage form having a controlled and prolonged release pattern upon administration, the carrier base material being a mixture of one or more nonionic cellulose ethers and an anionic surfactant, and wherein at least one of the cellulose ethers is a modified hydroxypropylmethylcellulose having a number average molecular weight of less than 50,000 and has been modified by successive or concurrent exposure to moisture and air.

Abstract: A mixture of nitroglycerin and a water-insoluble vinylpyrrolidone polymer provides a polymeric matrix which gradually releases nitroglycerin upon application to the skin of a patient in the form of a film, gel or ointment. The water-insoluble vinylpyrrolidone polymer may be an uncrosslinked copolymer or a crosslinked homopolymer or copolymer. The polymer provides increased stability and reduced volatility of the nitroglycerin while permitting slow and sustained release of the drug upon topical application to the skin.

Abstract: A carrier base material combined with a therapeutically active medicament and shaped and compressed to a solid unit dosage form having a regular and prolonged release pattern upon administration, the carrier base material being one or more hydroxypropylmethylcelluloses or a mixture of one or more hydroxypropylmethylcelluloses and up to 30% by weight of the mixture of methylcellulose, sodium carboxymethylcellulose and/or other cellulose ether, and wherein at least one of the hydroxypropylmethylcelluloses has a methoxy content of 16-24 weight-%, a hydroxypropoxyl content of 4-32 weight-% and a number average molecular weight of at least 50,000 and wherein the carrier base material constitutes less than about one third of the weight of the solid unit dosage form.

Abstract: A carrier base material combined with a therapeutically active medicament and shaped and compressed to a solid unit dosage form having a regular and prolonged release pattern upon administration, the carrier base material being hydroxypropylmethylcellulose or a mixture of hydroxypropylmethylcellulose and up to 30% by weight of the mixture of ethylcellulose and/or up to 30% by weight of the mixture of sodium carboxymethylcellulose, and wherein the hydroxypropylmethylcellulose has a hydroxypropoxyl content of 9-12 weight % and a number average molecular weight of less than 50,000.

Abstract: A carrier base material adapted to be combined with a therapeutically active medicament and shaped and compressed to form a sustained release therapeutic composition having a long-lasting, slow and regular incremental release of the medicament upon administration, the carrier base material being hydroxypropylmethylcellulose or a mixture of hydroxypropylmethylcellulose and either up to 30% ethylcellulose or 30% sodium carboxymethylcellulose or both, and wherein the carrier base material has been subjected to hydrolysis and oxidation successively or concurrently until the carbonyl content ranges from 0.2-3.0 grams/100 grams, the carboxyl content ranges from 0.60-2.60 grams/100 grams and the moisture content is in the range of 0.5-3.9%.

Abstract: Shaped pharmaceutical tablets, lozenges, suppositories and other solid dosage unit forms which have a prolonged and regular release pattern of a therapeutically active medicament incorporated therein, wherein the shaped dosage unit comprises a carrier base material of hydroxypropylmethylcellulose or a mixture thereof with up to 30% ethylcellulose and/or up to 30% sodium carboxymethylcellulose and wherein the carrier base material is subjected to hydrolysis and oxidation so as to generate thereon a desired minimum concentration of carbonyl and carboxyl groups, and then admixed and shaped with a therapeutically active medicament.
