Acute effects of pirenzepin on bronchospasm.
The response to pirenzepin, a new acetylcholine receptor blocking agent, was assessed and compared to placebo in patients with reversible bronchoconstriction. A single intravenous injection of 20 mg of pirenzepin induced a significant reduction of airway resistance compared to placebo (p less than 0.05). The anticholinergic substance pirenzepin appears to be useful in the treatment of bronchospasm.
