title: Effect of diltiazem, nifedipine and verapamil on the antinociceptive action of acetylsalicylic acid in mice.
abstract: 1. Diltiazem, verapamil and nifedipine produced a dose-dependent analgesic response in mice. 2. A fixed oral dose of acetylsalicylic acid increased this analgesic response. 3. Analgesia was maintained when mice were treated chronically with calcium channel blockers alone or when combined with aspirin.
