Brief:

This is the standard first question for all the HK pharmacy legislation exams (with different drugs each time). Whilst it may not be possible to answer every one correctly under exam conditions, with preparation scoring fairly high marks on this question is feasible.

I will give a brief introduction to each drug just for context and CPD, but the only answer the examiner requires is the classification in the abbreviated form.

Pay attention to the form and the strength specified, and bear in mind some DDs, and some products with more than one drug may have dual classification.
