Indications & Clinical Uses

Ketonal (ketoprofen) is used to manage pain and inflammation across several musculoskeletal and postoperative conditions.

  • Rheumatoid arthritis: reduces joint pain, swelling and stiffness.
  • Osteoarthritis: alleviates chronic joint discomfort and improves mobility.
  • Musculoskeletal pain: provides rapid relief of strain, sprain and back pain.
  • Postoperative pain: controls acute pain following surgical procedures.
  • General inflammatory conditions: diminishes swelling and erythema in acute inflammatory episodes.

How It Works

  • Ketoprofen exerts its effect by non‑selectively inhibiting cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, which blocks the conversion of arachidonic acid to prostaglandins. The resulting decrease in prostaglandin synthesis reduces inflammation, pain signaling, and fever, providing analgesic and anti‑inflammatory activity at the site of tissue injury.

Side Effects

Ketonal may cause a range of adverse reactions, from mild to severe. Awareness of these effects helps clinicians monitor patients appropriately.

Common Side Effects

  • Gastrointestinal discomfort: nausea, dyspepsia or abdominal pain.
  • Headache: mild to moderate intensity.
  • Dizziness or vertigo.
  • Injection site reactions: erythema, swelling or pain.
  • Transient elevation of liver enzymes.
  • Mild renal function changes.

Serious or Rare Side Effects

  • Severe gastrointestinal bleeding or ulceration.
  • Acute renal failure or significant creatinine rise.
  • Anaphylactic or severe hypersensitivity reactions.
  • Cardiovascular events such as myocardial infarction or stroke.
  • Hepatotoxicity with marked transaminase elevation.
  • Blood dyscrasias including thrombocytopenia.

Precautions & Warnings

When prescribing Ketonal, clinicians should consider several safety aspects to minimise risk.

  • Renal function: assess baseline kidney status and monitor during therapy.
  • Gastrointestinal risk: avoid in patients with active ulcers or a history of serious GI bleeding.
  • Cardiovascular health: use cautiously in uncontrolled hypertension or known cardiovascular disease.
  • Bleeding tendency: evaluate before surgery or in patients on anticoagulants.
  • Drug interactions: review concomitant medications for potential additive toxicity.
  • Store below 25°C: keep in the original container, protect from light and moisture.

Avoid Interactions

Ketonal can interact with various medicines, altering efficacy or safety.

Major Interactions (Avoid)

  • Anticoagulants (e.g., warfarin): heightened risk of serious bleeding.
  • Selective COX‑2 inhibitors: additive renal and gastrointestinal toxicity.
  • Lithium: increased serum lithium concentrations leading to toxicity.

Moderate Interactions (Monitor Closely)

  • ACE inhibitors or ARBs: possible reduction in renal function.
  • Loop or thiazide diuretics: enhanced nephrotoxic potential.
  • Methotrexate: reduced clearance and possible toxicity.

Frequently Asked Questions

Ketonal, which contains ketoprofen, is prescribed for moderate to severe pain and inflammation. It is commonly used in rheumatoid arthritis, osteoarthritis, musculoskeletal injuries, and to control postoperative pain after surgical procedures. The drug helps reduce swelling, stiffness, and discomfort associated with these conditions.

Ketoprofen works by blocking the activity of cyclooxygenase‑1 and cyclooxygenase‑2 enzymes, which are essential for producing prostaglandins. Prostaglandins amplify pain signals and promote inflammation, so their reduction leads to decreased swelling, pain perception, and fever, providing therapeutic relief.

The specific dose of Ketonal is determined by the prescribing healthcare professional based on the patient’s condition, weight, renal and hepatic function, and the route of administration. Only a qualified prescriber should set the dosage and frequency.

The safety of ketoprofen in pregnancy and lactation has not been definitively established. It is generally avoided during the third trimester because of potential fetal cardiovascular effects, and caution is advised for nursing mothers. Physicians should evaluate risks versus benefits before prescribing.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including cold‑chain if needed) and necessary import documentation.

Ketoprofen is generally more potent on a milligram‑per‑milligram basis than ibuprofen and has a longer half‑life, allowing less frequent dosing. Both share similar mechanisms (COX inhibition) and safety profiles, but ketoprofen may carry a slightly higher risk of gastrointestinal irritation, requiring careful patient selection.

Ketonal should be stored below 25 °C (77 °F) in its original packaging. Protect the product from direct light, moisture and extreme temperature fluctuations. Do not freeze the injection solution, and keep it out of reach of children.

Ketonal is supplied as a sterile injectable solution for intramuscular (IM) or intravenous (IV) administration. The injection is performed by a qualified healthcare professional under aseptic conditions, using the dose and route prescribed by the treating physician.

The most serious risks include severe gastrointestinal bleeding or ulceration, acute kidney injury, cardiovascular events such as heart attack or stroke, and life‑threatening allergic reactions (anaphylaxis). Patients should be monitored closely for signs of these complications, especially if they have pre‑existing risk factors.

Ketonal is contraindicated in patients with known hypersensitivity to ketoprofen or other NSAIDs, active gastrointestinal ulceration, severe renal or hepatic impairment, and in the third trimester of pregnancy. It should also be avoided in individuals with uncontrolled hypertension or a history of cardiovascular thrombotic events unless specifically directed by a physician.
