Mianserin-Mepha 30

Mianserin

Main Use Active Ingredient Manufacturer
Depression Mianserin Hydrochloride. Non-proprietary

How does it work?
Mianserin is a tetracyclic antidepressant that is similar to the tricyclic anti-depressants (TCAs).

When depression occurs, there may be a decreased amount of the chemicals noradrenaline and serotonin released from nerve cells in the brain. When these chemicals are released from nerve cells they act to lighten mood. When they are reabsorbed into the nerve cells, they no longer have an effect on mood.

Mianserin works by preventing the re-absorption of noradrenaline back into the nerve cells. It may also act to block certain receptors in the brain that bind released serotonin. This helps enhance and prolong the mood-lightening effect of any released noradrenaline and serotonin, thereby helping relieve depression.

The full benefits of treatment with mianserin may not appear for two to four weeks.

What is it used for?
Depression
