Zelamin Injection is a parenteral formulation combining Methylcobalamin (1500 mcg), Niacinamide (100 mg), and Vitamin B6 (Pyridoxine) (100 mg), designed to address various neurological and metabolic deficiencies. Methylcobalamin, an active form of Vitamin B12, plays a crucial role in nerve regeneration, myelin sheath synthesis, and hematopoiesis, making it effective in treating peripheral neuropathies, megaloblastic anemia, and certain neurodegenerative conditions. Niacinamide, a form of Vitamin B3, contributes to cellular energy production by participating in redox reactions and supports skin health, lipid metabolism, and DNA repair mechanisms. Vitamin B6 (Pyridoxine) is essential for amino acid metabolism, neurotransmitter synthesis, and hemoglobin formation, thereby aiding in the management of neuropathic pain, anemia, and certain metabolic disorders. The synergistic combination in Zelamin Injection enhances neuroprotective effects, improves nerve function, and supports overall metabolic homeostasis. This injectable preparation is indicated for patients with vitamin B deficiencies due to malabsorption, chronic alcoholism, diabetes mellitus, or drug-induced neuropathies. Administration should be under medical supervision, considering contraindications such as hypersensitivity to any component. Common adverse effects are rare but may include injection site reactions or mild gastrointestinal disturbances. Zelamin Injection offers a targeted therapeutic approach for rapid correction of vitamin B deficiencies and associated neurological impairments.
