Abstract: A multilayered tablet having three or more layers is provided which is useful for cholesterol lowering and reducing the risk of a myocardial infarction, which includes a first layer containing aspirin, another layer containing pravastatin, and a middle barrier layer, which preferably contains a buffering agent, which separates the first layer containing aspirin from the other layer containing pravastatin, and prevents or minimizes interaction of aspirin with pravastatin. A method for lowering cholesterol and reducing risk of a myocardial infarction employing such composition is also provided.

Abstract: There is provided in accordance with the present invention the quinolone antibacterial gatifloxacin adequately taste-masked so that it can be utilized for pediatric formulations. A crystalline co-precipitate of gatifloxacin and one or both of stearic acid and palmitic acid in a narrow weight ratio has been found to effectively mask the bitter taste of gatifloxacin. The taste of gatifloxacin is effectively masked in the mouth and in aqueous suspension through a full dosage cycle, typically fourteen days. Gatifloxacin in the subject crystalline co-precipitates has been found to be readily available for absorption from the stomach.
