Abstract
Pharmaceutical compositions containing enolic carboxamide type antiinflammatory agent meloxicam that exhibit improved wettability, aqueous solubility, dissolution behaviour over a broad range of pH, and that are prepared by crystal structure modification of the drug through dry or wet mechanical homogenization with two further components—one of them is selected from a group of oligo—and dissolution improving, or alkalizing agent. The application of the formulations according to the present invention results in an improved biovailability and effectiveness of meloxicam.
Claims22
Pharmaceutical composition comprising meloxicam as active ingredient, a cyclodextrin, a facultative oligosaccharide other than cyclodextrin, a facultative polysaccharide, one or more pharmaceutically acceptable additives selected from the group consisting of
- surfactants,
- hydrotropic agents,
- alkalizing agents,
- hydrocolloids and
- polymers
- and facultative excipients, carriers and/or auxiliary agents, wherein the pharmaceutical composition is obtainable by co-milling, co-grinding or co-kneading meloxicam in the presence of cyclodextrin as a pharmaceutically acceptable additive.
Pharmaceutical composition comprising meloxicam as active ingredient, a cyclodextrin and a facultativen oligosaccharide or polysaccharide, water as aqueous vehicle, a co-solvent and facultative auxiliary agents, wherein the pharmaceutical composition is obtainable by micronizing meloxicam in the presence of the cyclodextrin, the facultative oligosaccharide or polysaccharide, water and a co-solvent as pharmaceutically acceptable additive.
Pharmaceutical composition comprising meloxicam as active ingredient, a cyclodextrin and a facultative oligosaccharide or polysaccharide, water as aqueous vehicle, a co-solvent and facultative auxiliary agents, obtainable by wet mechanical homogenization of its components in the presence of water, preferably in an amount of 5 to 50% by weight (based on the total weight of the composition).
