Ibuprofen from the now outdated nomenclature iso-butyl-propanoic-phenolic acid) is a non-steroidal anti-inflammatory drug (NSAID) originally marketed as Brufen, and since then under various other trademarks (see tradenames section), most notably Nurofen, Advil and Motrin. It is used for relief of symptoms of arthritis, primary dysmenorrhea, fever, and as an analgesic, especially where there is an inflammatory component. Ibuprofen is known to have an antiplatelet effect, though it is relatively mild and short-lived when compared with that of aspirin or other better-known antiplatelet drugs. Ibuprofen is a core medicine in the World Health Organization's "Essential Drugs List", which is a list of minimum medical needs for a basic health care system.

Pharmacodynamics

Pharmacokinetics

Ibuprofen exhibits anti-inflammatory, analgesic and antipyretic activities. Its analgesic effect is independent of anti-inflammatory activity and has both central and peripheral effects. It potently inhibits the enzyme cyclooxygenase resulting in the blockage of prostaglandin synthesis. It also prevents formation of thromboxane A2 by platelet aggregation. Onset Analgesic: 30-60 min. Anti-inflammatory: ≤7 days. Duration 4-6 hr.


Absorption Oral: Peak plasma concentrations after 1-2 hr. Topical: Minimal.


Distribution Protein-binding: 90-99%.


Metabolism Hepatic via oxidation.


Excretion Via urine (1% as free drug), some feces; 2 hr (plasma half-life).

Precautions

Ibuprofen tablets cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids. The pharmacological activity of Ibuprofen tablets in reducing fever and inflammation may diminish the utility of these diagnostic signs in detecting complications of presumed noninfectious, painful conditions.

List of Contraindications

Ibuprofen and Pregnancy

Caution when used during pregnancy Category B: Either animal-reproduction studies have not demonstrated a foetal risk but there are no controlled studies in pregnant women or animal-reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the 1st trimester (and there is no evidence of a risk in later trimesters). In 3rd trimester or near delivery: Category D: There is positive evidence of human foetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).
