Absorption, Distribution and Excretion
Well absorbed with a bioavailability of 90%.
Mainly renal, with 0.4-0.5% being excreted in the urine as unchanged drug in healthy males. Renal excretion was the main route of elimination of the metabolites in man.
High plasma clearance (450–1000 1/h) in one study.

Metabolism / Metabolites
The drug is metabolized significantly through the hepatic system. From studies in dogs and rats, pirlindole has a bioavailability of between 20 and 30% due to the hepatic first-pass effect on this medication. The rat eliminates mainly unconjugated drug while the dog eliminates mostly conjugated drug.

LSM-1636 is a member of carbazoles.
This drug is classified as a reversible inhibitor of monoamine oxidase A enzyme (also known as a RIMA drug). It was developed and is currently used as an antidepressant in Russia. Its chemical structure is similar to metralindole, and it also shares pharmacological properties with this drug. Pirlindole is a selective, reversible inhibitor of monoamine oxidase (MAO) subtype A (MAO-A) that is approved in several European and non-European countries for the treatment of major depression. The antidepressant efficacy and safety of pirlindole have been demonstrated in numerous studies and, supported by many years of clinical experience in the treatment of depression. Pirlindole's efficacy and safety have also been shown in the treatment of fibromyalgia.

Drug Indication
For the treatment of major depression. It is being studied in the treatment of fibromyalgia pain syndrome. One study determined that the effect of pirlindole on sensorimotor performance while driving a motor vehicle shows many similarities to that of placebo. The drug appears to stimulate the central nervous system, rather than exhibit a sedative effect, like many antidepressants. Because of its selective, reversible inhibition of monoamine oxidase (MAO-A) and short half-life, unpleasant "cheese effects" are avoided. This refers to the effects of consuming tyramine-rich foods, such as cheese while medicated with monoamine oxidase inhibitors, leading to severe headaches and hypertension. of The available evidence supports pirlindole as a safe and effective treatment option for the management of depression and fibromyalgia syndrome.

Mechanism of Action
This drug is a selective and reversible inhibitor of monoamine oxidase A (also known as MAO-A). Its main mechanism of action is selective and reversible inhibition of monoamine oxidase A. Its secondary mechanism of action is the inhibition effect of noradrenaline and 5-hydroxytryptamine reuptake.

Pharmacodynamics
Pirlindole regulates that metabolism of norepinephrine and catecholamines, leading to relief of depressive symptoms. The prevention of breakdown of these neuromodulators is thought to elevate mood.
