They can take the role of doctors. They also replace prescribed drugs with others without doctors' permission. They can conduct unauthorized medical treatment that now became legal according to the newly amended pharmaceutical law. If pharmacists wants to practice medicine,they should have gone to medical school. They don't need to make and keep records of their compounding medical prescriptions.
Korean doctors write the medical records on what medications are prescribed.
Almost all the doctors in the world will do this. We don't know exactly how the other nation's pharmacists sell drugs. They probably sell OTC drugs on their decisions or by a patient's request or sell the drug according to a doctor's prescription. What do you do if you were grave after taking some drugs that a pharmacist gave you contrary to a doctor's prescription and the doctor do not know this. It's true we Korean doctors have gained some income from preparing and giving medicines before the amendment and partly this have maintained us but only this does not make us struggle.
