MODIFIED RELEASE NICORANDIL COMPOUND FORMULATIONS
Provided are compositions comprising nicorandil compound(s) in a controlled release formulation that releases at least about 30% of the nicorandil compound(s) into the intestine of human subjects. Such compositions can include a gastric acid dissolution susceptible component (GADSC) and a gastric acid dissolution resistant component (GADRC), wherein upon maintaining the composition in contact with a pH 1.2 dissolution media for a period of about 2 hours (1) the GADRC releases a statistically significantly smaller proportion of the one or more nicorandil compounds in the GADRC than the proportion of one or more nicorandil compounds release from the GADSC and (2) the composition releases no more than 50% of the one or more nicorandil compounds contained in the composition. The invention further provides methods of product such compositions and therapeutic uses of compositions, e.g., comprising once-daily administration of the composition to treat one or more diseases or conditions, including angina.
