Subsequent New Drug Approval (SND)

Subsequent New Drug Approval (SND)

Subsequent New Drug per se is not defined in the Drugs and Cosmetic Act 1940 and Rules 1945. However, it is an officially accepted term by the Indian Regulatory Authority, Central Drugs Standard Control Organization (CDSCO) in the context of approval of new drug products of same therapeutic class or of different therapeutic class for a new indication, new strength, new pharmaceutical dosage form or new route of administration. Hence, these drug products qualify for the definition of ‘New Drug’ of Drugs and Cosmetic Rules 1945 and fall under subsequent new drug application. Subsequent term is used by the CDSCO in their work practice; however it is not included in the Drugs & Cosmetic Act 1940 and Rules 1945.

CDSCO has categorized new drug in following category which can be called as Subsequent new drug (SND)

  1. Bulk Drug  already approved in the country
