Zelamin Plus Injection is a parenteral formulation combining Methylcobalamin (1000 mcg), Thiamine (Vitamin B1, 100 mg), Vitamin B6 (Pyridoxine, 100 mg), Nicotinamide (100 mg), and D-Panthenol (50 mg) designed to address deficiencies and support neurological and metabolic functions. Methylcobalamin, an active form of Vitamin B12, plays a critical role in nerve regeneration and hematopoiesis. Thiamine is essential for carbohydrate metabolism and neural function, while Pyridoxine contributes to amino acid metabolism and neurotransmitter synthesis. Nicotinamide, a form of Vitamin B3, is involved in cellular energy production and DNA repair. D-Panthenol, a provitamin of B5, supports coenzyme A synthesis, facilitating fatty acid metabolism and tissue repair. Zelamin Plus Injection is indicated for the treatment of peripheral neuropathies, vitamin B complex deficiencies, and metabolic disorders requiring rapid replenishment of B vitamins. It may also be used adjunctively in conditions such as diabetic neuropathy, alcoholic neuropathy, and other neurological impairments. The injection ensures prompt bioavailability, making it suitable for patients unable to tolerate oral administration. Administration should be under medical supervision, with dosage tailored according to clinical condition and response. Adverse reactions are rare but may include local injection site pain or hypersensitivity.
