Abstract
Pharmaceutical dosage units containing flupirtine or a pharmaceutically acceptable salt of flupirtine with controlled release of active substance using a delayed-action or controlled-release component. There are 0.001 to 20 parts delayed-action component for each part by weight flupirtine (calculated as the base) and the release rate of flupirtine is between 5 and 300 mg per hour. In some cases, the dosage units may also contain a rapidly releasing component of flupirtine or of one of its salts. The dosage units reduce the sedative effect of flupirtine.
