Ketonal Forte (Ketoprofen)

Ketonal Forte (ketoprofen) is used to manage pain and inflammatory disorders by reducing prostaglandin-mediated inflammation.

• Mild to moderate pain: provides relief of acute pain such as dental, postoperative, or musculoskeletal discomfort.
• Rheumatoid arthritis: reduces joint inflammation and improves functional ability in chronic rheumatoid disease.
• Osteoarthritis: alleviates joint pain and stiffness associated with degenerative osteoarthritis.
• Musculoskeletal pain: eases pain from strains, sprains, and other soft‑tissue injuries.

• Ketoprofen exerts its anti‑inflammatory and analgesic effects through non‑selective inhibition of cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes. By blocking these isoforms, it decreases the conversion of arachidonic acid to prostaglandins, which are key mediators of inflammation, pain, and fever. The reduced prostaglandin synthesis leads to diminished peripheral sensitization and inflammation. After oral absorption, ketoprofen distributes widely and attains therapeutic concentrations in inflamed tissues.

Ketonal Forte may cause a range of adverse reactions, varying from common, mild events to rare but serious conditions.

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia, or abdominal pain.
• Headache: mild to moderate intensity.
• Skin rash: mild erythema or pruritus.

Serious or Rare Side Effects

• Gastrointestinal ulceration or bleeding.
• Severe hypersensitivity reactions: anaphylaxis or Stevens‑Johnson syndrome.
• Renal impairment: acute kidney injury or reduced renal function.

When prescribing Ketonal Forte, clinicians should consider several precautionary measures to minimize risk.

• Assess renal function: avoid use or adjust dose in patients with impaired kidney function.
• Evaluate gastrointestinal risk: use with caution in individuals with a history of ulcers or bleeding.
• Monitor hepatic enzymes: periodic liver function tests are advised during prolonged therapy.
• Caution in cardiovascular disease: consider alternative therapy for patients with established heart disease.
• Avoid use in late pregnancy: ketoprofen is contraindicated in the third trimester.
• Store at ambient temperature: keep below 25 °C, in the original packaging, protected from moisture.

Ketonal Forte can interact with other medicines, altering efficacy or safety.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of bleeding.
• Other NSAIDs or aspirin: heightened gastrointestinal toxicity.
• Selective serotonin reuptake inhibitors (SSRIs): elevated bleeding potential.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or diuretics: may reduce renal function.
• Lithium: NSAIDs can increase lithium serum levels.
• Methotrexate: reduced clearance leading to toxicity.
