The injection you mentioned contains several active ingredients: methylcobalamin, thiamine HCl, pyridoxine HCl, D-panthenol, and nicotinamide. Here’s a brief description of each component:

1. Methylcobalamin: Methylcobalamin is a form of vitamin B12. It plays a vital role in nerve function, the production of red blood cells, and the maintenance of overall health. Methylcobalamin is commonly used to treat vitamin B12 deficiency and associated symptoms.

3. Pyridoxine HCl: Pyridoxine HCl, or vitamin B6, is involved in various metabolic processes, including protein and carbohydrate metabolism, as well as the production of neurotransmitters. Pyridoxine HCl is used to address vitamin B6 deficiency and related conditions.
4. D-Panthenol: D-Panthenol, also known as provitamin B5, is a moisturizing and soothing agent. It is often used in skincare products and wound healing formulations due to its ability to promote skin hydration and repair.
5. Nicotinamide: Nicotinamide, a form of vitamin B3, plays a crucial role in cellular energy production and DNA repair. It is often used to treat niacin (vitamin B3) deficiency and certain skin conditions.
