Biopharmaceutical studies of oral formulations containing propyphenazone.

Studies were performed with oral dosage formulations of propyphenazon, i.e. aqueous suspension (1%), instant suspension (1%) and tablets (100 mg) for pediatric use. The influence of the pharmaceutical adjuvants of the release of the drug from the model preparations was established. The biological availability determined from rabbits showed that the formulated preparations are biologically equivalent.
