Medications are substances used for medical treatments, primarily drugs and medicines.
Side effects are unintended effects not aligned with the primary therapeutic purpose of a medication.
Adverse effects refer to harmful or undesirable reactions resulting from medication use.

Pharmacology Principles

Pharmacodynamics explains the effects drugs have on the body.
Pharmacokinetics describes how the body processes and affects the administered drug.

Drug Interaction Types

Agonists are drugs that activate receptors to produce an effect.
Antagonists block substances from activating receptors.

Drug Absorption and Distribution

Absorption involves the uptake of drugs into the bloodstream from various administration routes.
Distribution details how extensively drugs spread throughout the body.

Drug Metabolism and Elimination

Metabolism is the biochemical process where drugs are broken down, primarily by enzymes.
The liver is the main site for drug metabolism.
Elimination refers to the removal of drugs from the body, occurring through urine, feces, or internal destruction.

Drug Bioavailability and Distribution Metrics

Bioavailability indicates the percentage of a drug dose that reaches systemic circulation.
Volume of distribution measures how broadly a drug disperses in the body.

Drug Biotransformation

Metabolites are the substances formed as a result of drug metabolism.
Half-life measures the duration that a drug's effects last within the body after administration.

Administration and Dosage

Routes of administration include oral, topical, and intravenous methods.
Dose refers to the specific quantity of medication administered.
Frequency indicates how often a medication is given.
Duration denotes the length of time the medication is administered.
Quantity is the total amount of medication to be ordered.

Prescriptions and Drug Classifications

A prescription is an order by a physician for patient treatment, necessitating pharmacist review.
Over-the-counter medications can be purchased without prescriptions, provided they include proper labeling.
Generic names signify the unique chemical composition of a medication.
Brand names are trademarked titles assigned by manufacturers who have gained FDA approval.
Off-label use involves prescribing drugs for indications beyond their approved uses.
