Drug absorption is the progression of the drug from the site of administration to the blood. Drugs that are taken orally will undergo little absorption until they reach the intestine whereas drugs that are administered intravenously will not need to be absorbed as they are injected straight into the blood. Other drug administration sites include; inhalation, topical (creams), intramuscular injection (into the muscle) or subcutaneous injection (under the skin).
