Pharmacology: Drug Administration Routes

Drug placed under the tongue for rapid absorption into the bloodstream.

Drug placed between cheek and gum for slower, sustained absorption.

Drug absorption through mucous membranes (e.g., sublingual, buccal).

Delivery of drugs into the bloodstream for widespread action throughout the body.

Drug breakdown by the liver before reaching systemic circulation.

Delivering drugs through mucous membranes like the mouth, nose, or rectum, bypassing initial liver breakdown.

Placing drugs under the tongue or between cheek and gum for quick absorption into the bloodstream.

Administering drugs through the lungs, often using inhalers, for fast action.

Administering drugs through the rectum, bypassing the stomach and liver.

Different ways to introduce drugs into the body, categorized as systemic (affecting the whole body) or local/site-specific (affecting a specific area).

When a drug enters the bloodstream and travels throughout the body, impacting multiple tissues.

When a drug is applied directly to a specific area, targeting the tissue that needs treatment.

Injecting a drug directly into a vein, allowing for fast and direct entry into the bloodstream.

Injecting a drug into a muscle, enabling absorption into the bloodstream through muscle tissue.

Injecting a drug under the skin, allowing for slower but sustained release into the bloodstream.

Applying a drug directly to the skin or mucous membranes, providing localized treatment.
