title: Absolute intramuscular, oral, and rectal bioavailability of alizapride.
abstract: A study was designed to estimate the absolute bioavailability of alizapride after intramuscular injection, oral administration as a solution or a tablet, and rectal administration as a suppository compared with that after intravenous injection. A balanced incomplete block-design trial was adopted. The intramuscular injection and the tablet administration showed identical results with those of the intravenous injection. On the contrary, the oral solution and the rectal suppository dosage forms gave lower absorption values, i.e., 75 and 61% of the dose administered was absorbed, respectively.
