Logidruf-S Solution is a topical medicated formulation containing Coal Tar 4.25% w/v and Salicylic Acid 2% w/v, indicated for the treatment of various scalp conditions such as psoriasis, seborrheic dermatitis, and dandruff. Coal Tar exerts its therapeutic effect by slowing down the rapid proliferation of skin cells and reducing inflammation, thereby alleviating scaling, itching, and redness associated with these disorders. Salicylic Acid acts as a keratolytic agent, promoting the softening and shedding of hyperkeratotic skin, facilitating the removal of scales and plaques. The combination of these active ingredients provides a synergistic effect, improving symptom control and enhancing patient comfort. Logidruf-S Solution is applied topically to the affected scalp areas, typically once or twice daily as directed by a healthcare professional. Caution is advised in patients with sensitivity to coal tar or salicylates, and it should be used with care in children and pregnant or lactating women. Avoid contact with eyes and mucous membranes. Regular use as prescribed can result in significant improvement in scalp condition and quality of life. Patients should consult their physician if irritation or adverse reactions occur.
