Hi Swasti!! Hope you are doing well!! If you want to open a medical store, there are no courses required to do, you can open a store as it is and sell medicine. To get the licenseBlicense toyto runnrun youetyour shop, you need to have a FULL TIME PHARMACIST REGISTERED IN PHARMACY COUNCIL for which you have to have a minimum degree of D.pharm. You will need to have  knowledge of the medicines to sell them , so it would be appropriate to do a course in medicines .
