Clomipramine is used to treat patients with obsessive-compulsive disorder.
Clomipramine is a tricyclic agent with both antidepressant and antiobsessional properties. Like other tricyclics, Clomipramine inhibits norepinephrine and serotonin uptake into central nerve terminals, possibly by blocking the membrane-pump of neurons, thereby increasing the concentration of transmitter monoamines at receptor sites. Clomipramine is presumed to influence depression and obsessive and compulsive behaviour through its effects on serotonergic neurotransmission. The actual neurochemical mechanism is unknown, but Clomipramine capacity to inhibit serotonin reuptake is thought to be important. Clomipramine appears to have a mild sedative effect which may be helpful in alleviating the anxiety component often accompanying depression.
