Method of enhancing bioavailability of pharmaceutical agents

摘要

The invention provides a pharmaceutical composition comprising a particular physical form of N-[4-[5-(cyclopentyloxycarbonyl)amino-1-methylindol-3-yl-methyl]-3-methoxybenzoyl]-2-methylbenzenesulphonamide and polyvinylpyrrolidone. It also provides methods for preparing this physical form, and another physical form of N-[4-[5-(cyclopentyloxycarbonyl)amino-1-methylindol-3-yl-methyl]-3-methoxybenzoyl]-2-methylbenzenesulphonamide useful in the preparation of the first mentioned physical form. The compositions are useful in the treatment of diseases in which leukotrienes are implicated, for example asthma.
