Ibuprofene Lysinate Substipharm (Ibuprofen Lysine)

• Ibuprofen lysine is an NSAID that reduces prostaglandin‑mediated inflammation and is indicated for the following conditions:
• Mild to moderate pain: provides analgesic relief for headaches, dental pain, and musculoskeletal discomfort.
• Fever: lowers elevated body temperature associated with infections or inflammatory states.
• Inflammatory arthritis: decreases joint swelling and improves mobility in osteoarthritis and rheumatoid arthritis.

• Ibuprofen lysine exerts its effect by reversibly inhibiting cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, which catalyze the conversion of arachidonic acid to prostaglandins. By decreasing prostaglandin synthesis, it reduces inflammation, pain signaling, and fever generation at peripheral and central sites. The lysine salt form enhances solubility, allowing rapid absorption after oral administration, leading to prompt onset of action.

Adverse reactions to ibuprofen lysine may vary in frequency and severity.

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia or abdominal pain.
• Headache: mild to moderate intensity.
• Dizziness: transient sensation of light‑headedness.
• Rash: mild skin erythema or itching.

Serious or Rare Side Effects

• Gastrointestinal ulceration or bleeding: potentially life‑threatening hemorrhage.
• Severe hypersensitivity: anaphylaxis, angioedema, or bronchospasm.
• Renal impairment: acute kidney injury, especially with dehydration or concurrent nephrotoxic drugs.

When prescribing ibuprofen lysine, consider the following precautions:

• Assess renal function: avoid use in patients with severe renal impairment.
• Monitor gastrointestinal risk: use with caution in history of ulcers or bleeding.
• Avoid in known hypersensitivity: discontinue if allergic reactions occur.
• Use cautiously with anticoagulants: increased bleeding risk.
• Pregnancy and lactation: consult healthcare professional before use.
• Store at ambient temperature: keep below 25 °C, in original packaging, protected from moisture and light.

Ibuprofen lysine can interact with several medicines; awareness of major and moderate interactions helps prevent adverse outcomes.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): heightened bleeding risk.
• High‑dose aspirin: increased gastrointestinal ulceration.
• Lithium: reduced renal clearance, risk of toxicity.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: possible reduction in antihypertensive effect and renal function.
• SSRIs or SNRIs: increased bleeding tendency.
