Trimipramine is a drug that is used mainly to treat depressive states, although it is also prescribed in the case of sleep and anxiety disorders, as well as in some psychosomatic disorders. Due to its high risk of generating adverse effects, this drug is usually prescribed with strict medical supervision.
Next we will see what trimipramine is what it is for, what its possible adverse effects are and how it is marketed.
What is trimipramine and what is this drug for?
Trimipramine is a tricyclic antidepressant that has sedative and anticholinergic properties The latter act both centrally and peripherally in the nervous system. Its mechanism of action is not completely known, but it is chemically related to another tricyclic type drug called imipramine.
Tricyclic and tetracyclic antidepressants are two of the first to be used in psychopharmacology. These are drugs that prevent the reuptake of serotonin, and sometimes norepinephrine, in the synaptic space, which produces a high concentration of these neurotransmitters and a reduction in some symptoms of depression
Trimipramine is mainly used to treat depressive states, whether mild or severe. But it is also used for the treatment of psychosomatic disorders that have a depressive background, as well as for anxiety states and sleep disturbances. The improvement associated with this drug generally occurs after the first few weeks, or sometimes a little longer, after starting treatment.
At the same time, that is, during the first phases of recovery, the risk of suicide that often accompanies depression can increase Therefore, it is recommended to closely accompany the person until the first signs of improvement occur.
In fact, until recently, tricyclic and tetracyclic drugs were among the most widely used antidepressants. However, since they have a non-specific mechanism of action, these drugs usually affect other substances important to the body (such as acetylcholine, histamine and dopamine). This increases the probability of suffering adverse effects, as well as mortality due to overdose, which is why its prescription has been reduced.
