摘要:
The present invention comprises compositions for pharmaceutical drug delivery of an indolone (e.g., ropinirole), or a pharmaceutically acceptable salt thereof. The composition may, for example, be a gel suitable for transdermal application. The compositions of the present invention typically comprise a hydroalcoholic vehicle, one or more antioxidant, and one or more buffering agent, wherein the pH of the gel is usually between about pH 7 and about pH 9. The compositions may include further components, for example, the hydroalcoholic vehicle may further comprise additional solvent(s), antioxidant(s), cosolvent(s), penetration enhancer(s), buffering agent(s), and/or gelling agent(s). The compositions may be used for the treatment of a variety of neurological disorders.

摘要:
The present invention relates to a rapidly disintegrating orally administratable solid dosage formulation that includes at least one active ingredient, at least one first disintegration agent that is at least one type-C methacrylic acid copolymer according to the U.S. Pharmacopoeia National Formulary US/NF, a second disintegration agent of crospovidone or a cross-linked povidone polymer derivative thereof, and a non-cariogenic diluent that does not increase glucose blood levels. The at least one first disintegration agent does not function as an enteric coating, insulation coating intended to protect active ingredient(s), or coating intended to mask taste or smell. The solid dosage form has a mass of about 50 to about 1000 mg, and the at least one first disintegration agent is present in the dosage form in an amount not exceeding 15%, with respect to the total weight of the dosage form. The second disintegration agent is present in the dosage form in an amount not exceeding 15% with respect to the total weight of the dosage form. The first and the second disintegration agent are present in total amounts that provide a weight ratio of about 1:1 to about 1:3, wherein the dosage form provides at least one of the in vitro or in vivo disintegration time that is less than 30 seconds, and has a friability of 1% or less according to the U.S. Pharmacopoeia test.

摘要:
The invention relates to a transdermal or transmucosal non-occlusive, semi-solid pharmaceutical formulation that includes at least one systemically active agent that acts on the Central Nervous System (CNS) of a mammal; and a permeation enhancing solvent system present in an amount sufficient to solubilize the at least one active ingredient. The permeation enhancing solvent system includes a pharmaceutically acceptable monoalkyl ether of diethylene glycol; a pharmaceutically acceptable glycol; preferably also a fatty alcohol and or a fatty acid; and a mixture of a C2 to C4 alcohol and water so that the permeation enhancing solvent system (a) inhibits crystallization of the at least one active ingredient on a skin or mucosal surface of a mammal, (b) reduces or prevents transfer of the formulation to clothing or to another being, (c) modulates biodistribution of the at least one active agent within different layers of skin, (d) facilitates absorption of the at least one active agent by a skin or a mucosal surface of a mammal, or (e) provides a combination of one or more of (a) through (d).
