Ibuprofen Pfleger (Ibuprofen D,l-Lysinate)

Ibuprofen acts on the cyclooxygenase pathway to provide analgesic, antipyretic, and anti‑inflammatory effects.

• Pain: Provides relief of mild to moderate acute pain such as headache, dental pain, musculoskeletal aches, and dysmenorrhea by decreasing prostaglandin‑mediated nociception.
• Fever: Lowers elevated body temperature associated with viral or bacterial infections through inhibition of prostaglandin E2 synthesis in the hypothalamus.
• Inflammation: Reduces swelling and stiffness in conditions like osteoarthritis, rheumatoid arthritis, and soft‑tissue injuries by limiting inflammatory prostaglandin production.

• Ibuprofen D,l‑Lysinate is a reversible inhibitor of both cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes. By blocking these enzymes, it reduces the conversion of arachidonic acid to prostaglandins and thromboxanes, leading to decreased inflammation, pain signaling, and fever generation.

Common Side Effects

• Gastrointestinal discomfort such as nausea, dyspepsia, or abdominal pain.
• Headache or dizziness.
• Mild skin rash or itching.
• Elevated blood pressure in some individuals.

Serious or Rare Side Effects

• Gastrointestinal bleeding, ulceration, or perforation.
• Acute renal impairment or worsening of chronic kidney disease.
• Severe allergic reactions including anaphylaxis.
• Hepatic injury manifested by jaundice or elevated liver enzymes.
• Cardiovascular events such as myocardial infarction or stroke, particularly with high‑dose or prolonged use.

Before using Ibuprofen Pfleger, consider the following precautions:

• Assess renal function: avoid use in patients with severe renal impairment.
• Monitor gastrointestinal risk: use the lowest effective dose in individuals with a history of ulcers or bleeding.
• Use with food or antacids to reduce stomach irritation.
• Avoid in the third trimester of pregnancy unless clearly indicated.
• Keep under medical supervision when combined with anticoagulants or other NSAIDs.
• Store at ambient temperature: keep in the original packaging, protect from moisture and direct sunlight.

Ibuprofen can interact with several drug classes. Review the following interactions:

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• Concurrent NSAIDs or aspirin: additive gastrointestinal toxicity.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may reduce renal perfusion and function.
• Diuretics: potential for decreased renal clearance.
• Lithium: ibuprofen may raise lithium serum concentrations, requiring monitoring.
