Momentact (Ibuprofen)

Ibuprofen acts systemically to alleviate pain, lower temperature, and suppress inflammation associated with common musculoskeletal and febrile conditions.

• Mild to moderate pain: provides analgesic relief by decreasing prostaglandin‑mediated nociception.
• Fever: reduces elevated body temperature through central inhibition of prostaglandin synthesis.
• Inflammatory conditions such as arthritis: diminishes joint swelling and discomfort by limiting inflammatory prostaglandin production.

• Ibuprofen non‑selectively inhibits cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, which blocks the conversion of arachidonic acid to prostaglandins. The resulting decrease in prostaglandin levels reduces inflammation, pain signaling, and fever generation at peripheral and central sites.

Adverse reactions may range from mild, transient symptoms to serious, potentially life‑threatening events.

Common Side Effects

• Gastrointestinal upset: nausea, dyspepsia, or abdominal discomfort.
• Headache or dizziness.
• Mild rash or pruritus.
• Transient elevation of liver enzymes.
• Fluid retention or mild edema.

Serious or Rare Side Effects

• Gastrointestinal bleeding, ulceration, or perforation.
• Severe hypersensitivity reactions, including anaphylaxis or Stevens‑Johnson syndrome.
• Acute renal failure or significant decline in renal function.
• Hepatotoxicity with marked liver enzyme elevation.
• Cardiovascular events such as myocardial infarction or stroke, particularly with high‑dose or prolonged use.

Before initiating therapy, consider the following safety measures.

• Assess renal function: adjust or avoid use in patients with significant kidney impairment.
• Evaluate gastrointestinal risk: avoid in individuals with a history of peptic ulcer disease or bleeding.
• Review concomitant anticoagulant or antiplatelet therapy: increased bleeding risk may require monitoring.
• Use with caution in asthma: NSAIDs can precipitate bronchospasm in sensitive patients.
• Pregnancy and lactation: consult a healthcare professional before use during these periods.
• Store at ambient temperature: keep in the original container, protect from moisture and heat.

Ibuprofen may interact with several drug classes, altering efficacy or safety.

Major Interactions (Avoid)

• Anticoagulants such as warfarin: heightened risk of serious bleeding.
• Selective serotonin reuptake inhibitors (SSRIs): increased gastrointestinal bleeding potential.
• Lithium: ibuprofen can raise serum lithium concentrations, risking toxicity.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may reduce renal perfusion, especially in volume‑depleted patients.
• Diuretics: combined use can impair kidney function.
• Methotrexate: ibuprofen may decrease clearance, leading to elevated methotrexate levels.
