The question asks which schedule of the Drugs and Cosmetics Act in India does not permit the repacking of drugs. Let's analyze the options to identify the correct answer.
- Schedule H:
- This schedule contains prescription drugs, which can only be sold by a pharmacist on the prescription of a registered medical practitioner.
- It does not specifically mention repacking restrictions.
- Schedule G:
- This includes drugs that require special directions on the label “Caution: it is dangerous to take this preparation except under medical supervision.”
- Repacking restrictions are not specifically mentioned.
- Schedule O:
- This schedule relates to the standards for disinfectant fluids.
- There is no specific mention about restrictions on repacking.
- Schedule C and C1:
- This schedule includes biological and special products like sera, vaccines, toxins, etc.
- The rules under this schedule specifically do not permit the repacking of such drugs to ensure their safety, efficacy, and stability as they are sensitive biologicals.
After examining the options, it's clear that Schedule C and C1 are the schedules that specifically prohibit repacking of drugs, which include sensitive biological products that require strict controls to retain their efficacy. Hence, the correct answer is Schedule C and C1.
