In many countries, OTC or non-prescription drugs are selected by a regulatory agency so as to check the ingredients that are used in the making of drugs are safe and effective when used without a doctor's advise. These non-prescription drugs are usually regulated by active pharmaceutical ingredients (APIs), not final products. This implies that the governments allow drugs manufacturers the right to formulate ingredients, or combinations of ingredients, to make proper medicinal mixtures. Regulations related to who is authorized to dispense these drugs, to where they are to be sold, and whether a prescription is required vary considerably from country to country. In India. all the drugs that are not included in the list of prescription drugs are considered as non-prescription drugs (or OTC drugs).
When and how much to take
NSAIDs should ideally be taken with some food, or at least with milk or yoghurt to avoid irritation of the gastric mucosa (. the inner lining of the stomach). It is important not to exceed the recommended dose to avoid possible serious side-effects. There is also no benefit in taking more than a certain dose, since these drugs have a ceiling effect. This means that above a certain dose, taking even more of this medication will not yield any extra beneficial effects, but will considerably increase the risk for side-effects.
