1. Explain in detail various types of Pharmaceutical Products.
Pharmaceutical Products are broadly of two types as follows :
1- Prescription products : also known as prescription medication or prescription medicine, is a licensed medicine that is regulated by legislation to require a medical prescription before it can be obtained.

Often a lower strength of a drug will be approved for OTC use, while higher strengths require a prescription to be obtained; a notable case is ibuprofen, which has been widely available as an OTC pain killer since the mid-1980s but is still available by prescription in doses up to four times the OTC dose for use in cases of severe pain not adequately controlled by the lower, OTC strength. In many countries, OTC drugs are selected by a regulatory agency to ensure that they are ingredients that are safe and effective when used without a physician's care. Some drugs may be legally classified as over-the-counter (i.e., no prescription is required), but may only be dispensed by a pharmacist after an assessment of the patient's needs and/or the provision of patient education. In many countries, a number of OTC drugs are available in establishments without a pharmacy, such as general stores,...
