Routes of Drug Administration

The oral route is most likely to lead to the first-pass effect.
Rectal suppositories intended for adult use usually weigh approximately 1-2 grams.

Bioavailability

The intravenous route has the highest bioavailability.

Pharmaceutical Bases

Vanishing cream is classified as a water-washable base.

Pharmacokinetics

The study of absorption, distribution, metabolism, and excretion of drugs is known as pharmacokinetics.
The advantage of sublingual route of drug administration is that it avoids first-pass effect.
The principle site of drug absorption for a drug given orally is the small intestine.

Dosage Calculations

If a patient is prescribed an intramuscular injection of 1 ml of 2% papaverine hydrochloride solution, 2 times a day, the daily dose is 40 mg.

Drug Metabolism

Glucuronidation is a phase II drug-metabolizing reaction.

Drug Absorption

A drug taken orally absorbs and enters the bloodstream faster from a solution dosage form.

Pharmacokinetic Principles

Pharmacokinetics is the study of absorption, distribution, metabolism, and excretion of drugs.
The liver has the greatest capacity to biotransform drugs.
The passage of drug molecules from a region of high drug concentration to a region of low drug concentration is known as diffusion.
Clearance is a pharmacokinetic indicator that characterizes the volume of drug cleared from the body per unit time.
Protonation refers to the process of acceptance of a proton (H+ ion) by a drug molecule.
The volume of distribution (Vd) relates to the apparent volume of fluid that contains the total amount of drug in the body.
