Ketifexin (Ketoprofen Lysine)

Ketifexin, a ketoprofen‑based NSAID, acts on inflammatory pathways to reduce pain and swelling.

• Mild to moderate pain: provides analgesic relief for everyday aches.
• Rheumatoid arthritis: helps control joint inflammation and stiffness.
• Osteoarthritis: reduces pain and improves joint function.
• Musculoskeletal pain: eases strain‑related discomfort in muscles and tendons.
• Dysmenorrhea: alleviates menstrual‑related cramping and pain.

• Ketoprofen lysine reversibly inhibits cyclooxygenase‑1 and cyclooxygenase‑2 enzymes, decreasing the conversion of arachidonic acid to prostaglandins. Lower prostaglandin levels lead to reduced inflammation, pain signaling, and fever, providing symptomatic relief in acute and chronic inflammatory conditions.

Ketifexin may cause a range of adverse reactions, from mild to serious.

Common Side Effects

• Gastrointestinal upset: nausea, dyspepsia, or abdominal discomfort.
• Headache: mild to moderate intensity.
• Dizziness or vertigo.
• Skin rash or mild itching.
• Elevated liver enzymes detected on routine labs.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulcer perforation.
• Acute renal failure or worsening of chronic kidney disease.
• Severe hypersensitivity reactions such as Stevens‑Johnson syndrome.
• Anaphylactic shock.
• Hepatotoxicity with jaundice.

Before using Ketifexin, consider the following safety measures.

• Assess gastrointestinal risk: avoid in patients with active ulcers or a history of GI bleeding.
• Monitor renal function: use cautiously in those with impaired kidney function.
• Evaluate cardiovascular risk: limit use in patients with uncontrolled hypertension or heart disease.
• Use the lowest effective dose for the shortest duration needed.
• Avoid in individuals with known hypersensitivity to ketoprofen or other NSAIDs.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Ketifexin can interact with several medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased bleeding risk.
• Other NSAIDs or aspirin: additive gastrointestinal toxicity.
• Corticosteroids: heightened ulcer risk.
• Lithium: elevated lithium serum levels.
• Methotrexate: reduced clearance leading to toxicity.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: possible reduction in renal function.
• Diuretics: may impair kidney perfusion.
• SSRIs or SNRIs: modest increase in bleeding tendency.
• Antihypertensives: potential attenuation of blood‑pressure control.
• Oral hypoglycemics: may affect glucose regulation.
