Introduction

Ketoprofen is a widely used nonsteroidal anti-inflammatory drug (NSAID) known for its efficacy in managing pain and inflammation. It is commonly prescribed for a variety of conditions, including arthritis and other musculoskeletal disorders. This essay provides a comprehensive overview of ketoprofen, including its dosage forms, indications, mechanism of action, administration, and potential side effects.

What It Is

Ketoprofen is a nonsteroidal anti-inflammatory drug (NSAID) that belongs to the propionic acid class of NSAIDs. It is used to relieve pain, reduce inflammation, and lower fever. Ketoprofen's effectiveness stems from its ability to inhibit the production of prostaglandins, which are chemicals in the body that mediate inflammation, pain, and fever.

Dosage Forms and Strengths

Ketoprofen is available in several dosage forms and strengths to accommodate different patient needs:

• Oral Tablets: Typically available in strengths of 25 mg, 50 mg, and 75 mg.
• Extended-Release Tablets: Commonly provided in 100 mg and 200 mg strengths.
• Capsules: Usually available in 50 mg and 100 mg strengths.
• Topical Gel: Generally available in a 5% concentration.
• Injectable Form: Often available in a 30 mg/mL concentration for intravenous or intramuscular administration.

Brand and Generic Names

Ketoprofen is marketed under various brand names, including:

• Orudis: Commonly used for its oral tablet form.
• Oruvail: Known for its extended-release tablets.
• Kétoprofène: The generic name used in many countries.

Indications for Use

Ketoprofen is indicated for:

• Rheumatoid Arthritis: To reduce joint inflammation and pain.
• Osteoarthritis: For pain relief and improvement in joint function.
• Dysmenorrhea: To alleviate pain associated with menstrual cramps.
• Acute Pain: Such as pain following surgery or injury.
• Minor Musculoskeletal Pain: Including pain from strains and sprains.

Mechanism of Action

Ketoprofen works by inhibiting the enzyme cyclooxygenase (COX), which is crucial in the synthesis of prostaglandins. There are two main types of COX enzymes: COX-1 and COX-2. Ketoprofen inhibits both, leading to a reduction in prostaglandin levels. Prostaglandins are involved in promoting inflammation, pain, and fever. By lowering their levels, ketoprofen alleviates symptoms associated with these conditions.

Administration and Dosage

The administration of ketoprofen depends on the formulation:

• Oral Tablets/Capsules: Typically taken with food to reduce gastrointestinal irritation. The usual starting dose is 25 mg to 50 mg every 6 to 8 hours, with a maximum daily dose of 300 mg for oral forms.
• Extended-Release Tablets: Usually taken once daily, with the dose ranging from 100 mg to 200 mg.
• Topical Gel: Applied to the affected area 3 to 4 times a day. The recommended amount should be gently rubbed into the skin.
• Injectable Form: Doses vary based on the clinical situation and should be administered by a healthcare professional.

Effects and Precautions

Side Effects:

Common side effects include:

• Gastrointestinal issues such as nausea, vomiting, and diarrhea.
• Abdominal pain and dyspepsia.
• Headache and dizziness.
• Rash or itching.

Serious side effects:

• Gastrointestinal bleeding or ulcers.
• Kidney impairment.
• Cardiovascular issues like hypertension or heart attack.
• Allergic reactions including anaphylaxis.

Precautions:

• Gastrointestinal Risk: Ketoprofen may increase the risk of gastrointestinal bleeding or ulceration, particularly with long-term use. It should be used with caution in patients with a history of peptic ulcer disease or gastrointestinal bleeding.
• Renal Impairment: The drug should be used cautiously in patients with kidney disease, as it may exacerbate renal function decline.
• Cardiovascular Risk: Use with caution in patients with cardiovascular disease, as NSAIDs can increase the risk of heart attack or stroke.
• Pregnancy and Lactation: Ketoprofen is generally avoided during the third trimester of pregnancy due to potential effects on fetal circulation and delivery. Consult a healthcare provider before use during pregnancy or breastfeeding.
