ATC code: N06AX25
Pharmacotherapeutic group: Other antidepressants, St. John's wort herb
The dry extract of St. John's wort inhibits the synaptosomal reuptake of the neurotransmitters noradrenaline, serotonin, and dopamine. Subchronic administration causes down-regulation of beta-adrenergic receptors; this alters the behaviour of experimental animals in certain antidepressant models (e.g. the forced swim test) in a manner similar to synthetic antidepressants.
The effect is contributed to by naphthodianthrones such as hypericin and pseudohypericin, phloroglucinol derivatives such as hyperforin, and flavonoids.
Clinical efficacy and safety
In controlled, double-blind and open-label studies compared with placebo, a significant improvement over placebo was shown in the symptoms of psychovegetative disorders — mood swings, low mood, nervous restlessness, and anxiety. Compared with various synthetic antidepressants such as amitriptyline, imipramine, or maprotiline, as well as benzodiazepines such as bromazepam, the St. John's wort extract demonstrated comparable efficacy with a substantially lower incidence of adverse effects.
