Metflow-Plus Injection is a parenteral formulation containing a combination of Methylcobalamin (1000 mg), 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 critical role in nerve regeneration, hematopoiesis, and DNA synthesis, making it essential for the treatment of peripheral neuropathies, megaloblastic anemia, and vitamin B12 deficiency states. Niacinamide, a form of Vitamin B3, contributes to cellular energy production through its involvement in NAD/NADP coenzymes and exhibits anti-inflammatory properties, supporting skin health and metabolic functions. Vitamin B6 (Pyridoxine) is vital for amino acid metabolism, neurotransmitter synthesis, and hemoglobin production, thereby aiding in the management of neuropathic pain, anemia, and certain metabolic disorders. The synergistic combination in Metflow-Plus Injection ensures enhanced bioavailability and rapid therapeutic action, particularly beneficial in patients with malabsorption issues or those requiring prompt correction of vitamin deficiencies. This injection is indicated for the treatment of peripheral neuropathy, diabetic neuropathy, vitamin B complex deficiencies, and related neurological conditions. Administration should be under medical supervision, with dosage tailored according to the severity of deficiency and clinical response. Caution is advised in patients with hypersensitivity to any components or underlying hepatic or renal impairment.
