Animal experiment: | Adult male mongrel dogs weighing 8 to 13 kg are used and anesthetized with sodium pentobarbital, 35 mg/kg i.v. Respiratory movement is measured by an accordion-type pneumograph placed around the thoraco-abdominal region and a pressure transducer. For the experiments on single i.v. injections, the increasing doses of Dimetacrine, 0.1, 0.3, 1, 3, 10 and 30 mg/kg i.v., until cardiac arrest occurs, are given into the cannulated left cephalic vein and are flushed with 1 mL of physiological saline. The changes in arterial blood pressure and heart rate caused by each dose are estimated for IMP, AMT and Dimetacrine[1]. |

Dimetacrine is a useful antidepressant which can be used for the treatment of various types of depression.
Dimetacrine is a useful antidepressant which can be used for the treatment of various types of depression. Dimetacrine in the highest concentration, 10 μM, decreases the contractile force to 36.5±9.1%. Dimetacrine, 0.3 μM, causes no statistically significant decline in contractile force from the controls. Tachycardia is observed after the administration of Dimetacrine, 1 to 3 mg/kg i.v., and the maximum response is obtained in dose of 3 mg/kg i.v.. The administration of Dimetacrine, 30 mg/kg i.v., causes an abrupt fall in blood pressure with tachycardia or bradycardia followed by cardiac arrest. Respiratory rate increases 40 min after the onset of infusion of Dimetacrine. Arterial blood pressure falls 50 min after the onset of infusion of Dimetacrine[1].

Effects of antidepressant drugs on a quickly-learned conditioned-suppression response in mice
Mice experienced to electric shock, exhibited a marked suppression of motor activity when placed in the same cage 24 hr after administration of shocks. Acute administration of imipramine-HCl (10 mg/kg, i.p.), desipramine-HCl (5 and 10 mg/kg, i.p.) and amitriptyline-HCl (5 and 10 mg/kg, i.p.) caused marked reduction of the conditioned suppression of shocked mice, but reduced the motor activity of the non-shocked mice. Maprotiline, mianserin and dimetacrine did not cause reduction of the conditioned suppression. Nialamide (100 mg/kg, i.p.) and pargyline-HCl (100 and 200 mg/kg, i.p.) caused marked reduction of the conditioned suppression but did not increase the motor activity of the non-shocked mice, and tranylcypromine-HCl (10 and 20 mg/kg, i.p.) did not cause reduction of the conditioned suppression. Diphenhydramine-HCl (10 and 20 mg/kg, i.p.) reduced the conditioned suppression of shocked mice in a dose-related manner. Chronic administration of imipramine-HCl (1 and 5 mg/kg, i.p.) for 14 days significantly reduced the conditioned suppression but did not influence the motility rate of the non-shocked mice. Also, chronic administration of amitriptyline (1 mg/kg, i.p.), desipramine (5 mg/kg, i.p.) and dimetacrine (10 mg/kg, i.p.), for 10 days, significantly reduced the conditioned suppression, but did not influence the motility rate of the non-shocked mice. Chronic administration of maprotiline reduced the conditioned suppression. On the other hand, chronic administration of mianserin (5 mg/kg, i.p.) and diphenhydramine (10 mg/kg, i.p.) did not cause a reduction of the conditioned suppression.
