In America, the Food and Drug Administration (FDA) has primary authority on the basic regulation and acceptance of medication. The Dept. of Homeland Security (formerly the Drug Enforcement Agency or DEA) controls distribution law.
Prescription drugs require a prescription from a doctor to get. Non-prescription drugs can be bought by anyone. Certain eye medicine and deodorant can be considered prescription drugs that have to be ordered. Other types of drugs, like advil and other pain killers can be bough as non-prescription drugs.
