The movement of medication throughout the blood, organs, and tissues after administration

A route of administration by way of intestine, such as orally, rectally, or sublingually

A process in which a portion of the drug dose is metabolized before the drug has a chance to be distributed systematically

1) the time required for a chemical to be decreased by half 2) The time needed / half the amount of a substance, such as a drug in a living system 3) The time required for the concentration of a substance in a body fluid (blood plasma) to decrease by hald

To place into; instillation instructions are commonly used for opthalmic or otic drugs

Drugs that require a prescription; these drugs carry the federal legend: "federal law prohibits the dispensing of this medication without a prescription"

The process by which the body breaks down or converts medications to active or inactive substances. The primary site of drug metabolism in humans is the liver; however, select drugs metabolize through other process

Over the Counter (OTC)

Medications that can be purchased without a prescription

A term used to describe a medication that is usually given by injection into a vein, the skin, the muscle, that bypasses the gastrointestinal system
