Hqtor Tablet contains Hydroxychloroquine 200mg, an antimalarial and immunomodulatory agent primarily used for the treatment and prevention of malaria. It is also indicated for the management of autoimmune diseases such as rheumatoid arthritis and systemic lupus erythematosus due to its ability to modulate the immune response and reduce inflammation. Hydroxychloroquine exerts its therapeutic effects by increasing the pH within intracellular vacuoles, interfering with lysosomal activity and antigen presentation, thereby inhibiting the proliferation of certain parasites and modulating immune cell function. Hqtor Tablet is administered orally and should be taken as prescribed by a healthcare professional. Common side effects may include gastrointestinal disturbances such as nausea, vomiting, and abdominal discomfort. Long-term use requires regular ophthalmologic monitoring to detect potential retinal toxicity, a rare but serious adverse effect. Caution is advised in patients with pre-existing retinal disease, cardiac conditions, or glucose-6-phosphate dehydrogenase deficiency. Hqtor Tablet should be used under medical supervision, with dosage adjustments based on clinical response and patient tolerance. It is contraindicated in individuals with hypersensitivity to Hydroxychloroquine or related compounds. Proper adherence to prescribed dosage and monitoring protocols ensures optimal therapeutic outcomes while minimizing risks.
