Maprotiline Hydrochloride Tablets

This product is a tetracyclic antidepressant. Its main function is to selectively inhibit the reuptake of norepinephrine in the peripheral and central nervous systems, while having no effect on the reuptake of 5-hydroxytryptamine. Due to the reduction of norepinephrine reuptake, the concentration of norepinephrine in the synaptic cleft increases, which downregulates the presynaptic membrane ?2 receptors and strengthens the postsynaptic membrane ?1 receptors, producing an antidepressant effect. This product also has an anti-anxiety effect, and its sedative, anticholinergic and blood pressure lowering effects are relatively mild.

The main ingredient of this product is: Maprotiline hydrochloride. Its chemical name is: N-methyl-9,10-ethanoanthracene-9 (10H)-propylamine hydrochloride. Molecular formula: C20H23NHCl Molecular weight: 313.87

However, it has not been determined to be safe for use during pregnancy. Individual cases have shown that the use of Ludiomil may be associated with adverse reactions to the human fetus. Ludiomil should not be used during pregnancy unless the benefits clearly outweigh the risks to the fetus.
