Uses
- Pain Relief: Effective in managing mild to moderate pain, including headaches, menstrual cramps, toothaches, and muscle aches.
- Anti-inflammatory: Reduces inflammation in conditions like arthritis, tendinitis, and bursitis.
- Antipyretic: Lowers fever in adults and children.
- Management of Chronic Conditions: Often used in the treatment of osteoarthritis and rheumatoid arthritis.
Dosage
Adults
- Pain and Fever: 200-400 mg every 4-6 hours as needed. Maximum daily dose: 3200 mg.
- Arthritis: 400-800 mg 3-4 times daily. Maximum daily dose: 3200 mg.

Side Effects
Common Side Effects
- Nausea

- Diarrhea
- Constipation
- Dizziness
- Headache
- Rash
Serious Side Effects
- Gastrointestinal bleeding or ulcers
- Heart attack or stroke

- Kidney dysfunction
- Severe allergic reactions (anaphylaxis)
- Liver damage
Pharmacokinetics
- Absorption: Rapidly absorbed from the gastrointestinal tract with peak plasma concentrations occurring 1-2 hours after administration.
- Distribution: Widely distributed throughout the body; 99% bound to plasma proteins.
- Metabolism: Metabolized in the liver via oxidation by cytochrome P450 enzymes, primarily CYP2C9.
- Excretion: Excreted primarily via urine as metabolites and their conjugates; half-life of approximately 2 hours.
Mechanism of Action
Ibuprofen works by inhibiting the activity of cyclooxygenase (COX) enzymes, specifically COX-1 and COX-2. These enzymes play a key role in the synthesis of prostaglandins, which are lipid compounds that mediate inflammation, pain, and fever. By reducing prostaglandin production, ibuprofen effectively diminishes these symptoms.
Adverse Effects
Ibuprofen can cause various adverse effects, ranging from mild to severe:
- Gastrointestinal: Ulcers, bleeding, perforation of the stomach or intestines.
- Cardiovascular: Increased risk of heart attack and stroke, particularly with long-term use or in individuals with pre-existing heart conditions.
- Renal: Kidney damage or failure, particularly in individuals with pre-existing kidney conditions or those taking other nephrotoxic drugs.
- Hepatic: Liver damage, including elevated liver enzymes and jaundice.
- Hematologic: Anemia, thrombocytopenia, and other blood disorders.
- Allergic Reactions: Severe skin reactions, anaphylaxis, and asthma exacerbation in susceptible individuals.

Conclusion
Ibuprofen is a versatile and widely used medication for managing pain, inflammation, and fever. While generally safe for most people when used as directed, it carries the risk of significant adverse effects, particularly with prolonged use or in individuals with certain health conditions. Understanding its pharmacokinetics, mechanism of action, and potential risks is crucial for its safe and effective use. Always consult a healthcare provider for personalized medical advice and before making any changes to your medication regimen.
