Immulina 800 Tablet contains Pidotimod 800 mg, an immunostimulant agent used to enhance the body’s immune response. Pidotimod is a synthetic dipeptide that modulates both innate and adaptive immunity by promoting the activation and proliferation of T-lymphocytes, increasing the production of cytokines, and enhancing phagocytic activity of macrophages. This mechanism helps in reducing the frequency and severity of recurrent respiratory tract infections, especially in patients with compromised or weakened immune systems. Immulina 800 is indicated as an adjunctive therapy in the management of chronic respiratory diseases such as bronchitis, chronic obstructive pulmonary disease (COPD), and recurrent upper respiratory tract infections. It may also be used to support immune function in patients undergoing immunosuppressive treatments or those with immunodeficiency conditions. The tablet is administered orally, with the dosage and duration tailored according to the clinical condition and physician’s discretion. Commonly, it is well tolerated with minimal adverse effects, though mild gastrointestinal discomfort or allergic reactions may occasionally occur. Immulina 800 should be used cautiously in patients with known hypersensitivity to Pidotimod or any tablet excipients. It is not recommended for use during pregnancy or lactation without medical advice.
