Tenaxit(Flupentixol & Melitracen)

Therapeutic Group: Drugs of Nervous System


Tenaxit tablet: Each tablet contains flupentixol dihydrochloride INN equivalent to 0.5 mg flupentixol and melitracen hydrochloride INN equivalent to 10 mg melitracen.


Tenaxit consists of two well known and well proven compounds: flupentixol- a neuroleptic with anxiolytic and antidepressant properties of its own when given in small doses, and melitracen - a bipolar thymoleptic with activating properties in low doses. In combination the compounds render a preparation with antidepressant, anxiolytic and activating properties.

Maximal serum concentration is reached in about 4 hours after oral administration of flupentixol and in about 4 hours after oral administration of melitracen. The biological half-life of flupentixol is about 35 hours and that of melitracen is about 19 hours. The combination of flupentixol and melitracen does not seem to influence the pharmacokinetic properties of the individual compounds.


Tenaxit is indicated in various types of anxiety, depression and apathy. These include-

* Psychogenic depression

* Depressive neuroses

* Masked depression

* Psychosomatic affections accompanied by anxiety and apathy

* Menopausal depressions

* Dysphoria and depression in alcoholics and drug-addicts

Use in Pregnancy & Lactation

Flupentixol-melitracen should preferably not be given during pregnancy and lactation.

Over Dose

Symptoms: In cases of overdosage the symptoms of intoxications by melitracen, especially of anticholinergic nature, dominate. More rarely extrapyramidal symptoms due to flupentixol occur.
Treatment: Symptomatic and supportive. Gastric lavage should be carried out as soon as possible and activated charcoal may be administered. Measures aimed at supporting the respiratory and cardiovascular systems should be instituted. Epinephrine (adrenaline) must not be used for such patients.
