Abstract

1 The cardiovascular responses of mianserin hydrochloride and tricyclic antidepressant drugs were investigated using non-invasive methods of cardiac investigation. A study of the interaction of mianserin and antihypertensive drug therapy is reported.

2 In six normal volunteers, mianserin hydrochloride 20 mg was shown to prolong the corrected Q-T interval at 150 min (P<0.001). It did not affect heart rate, systolic time intervals or the peak normalized derivative of the apexcardiogram. Amitriptyline 50 mg increased the corrected pre-ejection period interval (PEPI) and the PEP/left ventricular ejection time (LVET) ratio of the systolic time intervals at 150 min (P<0.001). Q-T interval was shortened at 90 minutes.

3 In a double-blind patient study, clomipramine increased heart rate, P-R interval, QRS and corrected Q-T interval in one patient at 2 weeks. Mianserin prolonged corrected Q-T interval at 1 week but this returned to the pretreatment time by 2 weeks in two patients.

4 In an open study, mianserin 20 mg three times daily did not antagonize the hypotensive action of propranolol or propranolol and hydrallazine in three patients.

5 In a double-blind study in three patients with desmethylimipramine 25 mg three times daily, mianserin 20 mg three times daily did not antagonize the hypotensive action of either guanethidine or bethanidine.
