Same salt, different brand — what does that mean?

A substitute contains the same active ingredient (salt), in the same strength, as Zanocin Oz Tablet. The medicine inside is the same — the brand name, manufacturer and price are what differ.

All medicines sold in India, branded or generic, must meet the quality standards set by the national drug regulator (CDSCO). A lower price does not mean lower quality.

Please confirm with your doctor or pharmacist before switching brands — they will check that the strength and form match your prescription.
