title: Prolactin and thyrotropin responses to ECT after pindolol administration. A placebo controlled study.
abstract: The effect of pindolol, a beta-receptor blocker with potent 5-HT1 receptor antagonistic properties, on the prolactin (PRL) and thyrotropin (TSH) responses to electroconvulsive therapy (ECT) was systematically studied in 12 female depressed patients. In a balanced order, crossover design, the patients were given placebo or pindolol 5 mg orally, 1 h prior to bilateral ECT. The last five patients were additionally tested with 10 mg pindolol during the third ECT. Plasma levels of PRL and TSH increased in all three trials, but no consistent effect of pindolol on these hormonal responses could be demonstrated. Pindolol tended to attenuate seizure duration, especially at the 10 mg dose. The participation of 5-HT1 receptor activity in the secretion of PRL and TSH during ECT remains uncertain.
