FARGAN ® Promethazine

FARGAN ® is a drug based on Promethazine

THERAPEUTIC GROUP: Antipruritic, including antihistamines, anesthetics etc.

Indications FARGAN ® Promethazine

FARGAN ® is successfully used in the treatment of skin itchy forms and localized skin irritation phenomena characterized by redness, burning and sunburn.

Mechanism of action FARGAN ® Promethazine

FARGAN ® is a medicinal product based on Promethazine, an antagonist of the histamine H1 receptor and therefore has a significant antihistamine effect which manifests itself in the anti-edematous, antipruritic and modestly anti-inflammatory activity of the drug.
However, the topical application of this active ingredient allows to limit some of the side effects classically related to systemic therapy with antihistamines such as Promethazine, such as the sedative effect on the Central Nervous System, due to the ability to easily cross the blood brain barrier, making thus the topical application of FARGAN ® is generally safe and well tolerated.
