<p>Zitlite 10 Capsule contains isotretinoin 10 mg, a potent retinoid primarily indicated for the treatment of severe recalcitrant nodular acne that has not responded adequately to conventional therapies such as systemic antibiotics and topical agents. Isotretinoin works by reducing sebaceous gland size and sebum production, inhibiting the growth of acne-causing bacteria, and exerting anti-inflammatory effects, thereby addressing multiple pathogenic factors of acne. This medication is typically prescribed under strict medical supervision due to its potential for significant adverse effects, including teratogenicity, mucocutaneous dryness, elevated liver enzymes, and lipid abnormalities. Patients should undergo baseline and periodic laboratory monitoring during therapy. It is contraindicated in pregnancy and women of childbearing potential must adhere to effective contraception measures before, during, and after treatment. Common side effects include cheilitis, dry skin, and photosensitivity. Dose adjustments may be necessary based on clinical response and tolerability. Zitlite 10 Capsule should be taken orally with food to enhance absorption. Due to its potent pharmacological effects, isotretinoin therapy requires careful patient education and follow-up to ensure safety and efficacy in managing severe acne vulgaris.</p>
