Zithranol is indicated for the topical treatment of psoriasis, particularly plaque psoriasis. It helps manage the symptoms of scaling, thickening, and inflammation associated with chronic psoriatic skin lesions.
The exact mechanism of action is not fully specified, but anthralin (the active ingredient) is believed to work by inhibiting cell proliferation and reducing inflammation in the skin, helping to normalize skin cell growth in affected areas.
Zithranol may cause skin irritation, staining of skin and fabrics, and should be used as directed by a healthcare provider. It is for external use only and should be avoided near eyes, mouth, and sensitive areas. Patients should follow their prescribed treatment schedule carefully and report any adverse reactions to their doctor.
