CA 2478411

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.

Formulation médicamenteuse se présentant sous la forme d'une poudre sèche qui, quand elle est mélangée à de l'eau, permet d'obtenir une suspension orale de goût agréable pratiquement exempte d'amertume. Cette poudre sèche est constituée par un médicament, de préférence, des-quinolone, qui possède un goût amer en solution, et par un agent modificateur de pH consistant, de préférence, en un matériau alcalin, tel que L-arginine. Le mélange de cette poudre sèche à de l'eau réduit la solubilité du médicament ou sa précipitation in situ afin de produire une suspension orale de goût agréable pratiquement exempte d'amertume. L'invention concerne également une suspension orale, ses procédés de préparation, ainsi qu'un procédé servant à masquer l'amertume de médicaments au moyen d'un ou de plusieurs agents modificateurs de pH.
