Over the Counter Medications. Drugs that are safe and effective for use by the general public without a prescription are defined as over-the-counter (OTC) drugs.
What is an over-the-counter market? The OTC is a market where financial instruments such as currencies, stocks and commodities are traded directly between two parties.

Instead, trading is usually carried out through a dealer network.
