Usage
This combination medication is prescribed for short-term relief of mild to moderate pain associated with various conditions, including headache, toothache, mild migraine, muscle pain, menstrual pain (dysmenorrhea), rheumatoid arthritis, ankylosing spondylitis, osteoarthritis, post-operative pain, post-traumatic pain, back pain, and flu-related aches.
Pharmacological Classification:
- Analgesic
- Anti-inflammatory
- Antacid
- Antipyretic (Paracetamol)
Mechanism of Action: This combination works through the synergistic action of its components:
- Nimesulide: A non-steroidal anti-inflammatory drug (NSAID) that selectively inhibits cyclooxygenase-2 (COX-2) enzyme, reducing prostaglandin synthesis, thus diminishing pain and inflammation.
- Paracetamol: An analgesic and antipyretic, it’s believed to inhibit prostaglandin synthesis in the central nervous system and influence the hypothalamic heat-regulating center, reducing fever and pain.
- Magnesium Trisilicate: An antacid that neutralizes stomach acid, relieving heartburn and indigestion. It also safeguards the stomach lining from potential adverse effects of NSAIDs.
Alternate Names
This combination is often marketed under various brand names, some of which include Napain Plus, Combilid P, Alleviate, and Nokia. Please note that availability and specific brand names may vary by region. Some product formulations may also include additional ingredients like Chlorpheniramine Maleate, an antihistamine for allergy symptom relief.
How It Works
Pharmacodynamics:
- Nimesulide: Primarily inhibits COX-2, reducing inflammation and pain.
- Paracetamol: Centrally acting analgesic and antipyretic, affecting the hypothalamic heat-regulating center and prostaglandin synthesis.
- Magnesium Trisilicate: Neutralizes gastric acid, offering gastroprotective action.
Pharmacokinetics:
All three components are absorbed orally. Nimesulide and paracetamol are metabolized in the liver. Magnesium trisilicate is not systemically absorbed. Elimination occurs through renal and hepatic routes.
Dosage
Standard Dosage
Adults: One tablet every 6-8 hours as needed. Do not exceed four tablets in a 24-hour period.
Special Cases:
-
Elderly Patients: Exercise caution and consider reduced dosages due to potential age-related decline in renal and hepatic function. Close monitoring for adverse effects is recommended.
-
Patients with Renal Impairment: Dose adjustment is needed in patients with moderate to severe renal dysfunction. Consult regional or product-specific guidelines.
-
Patients with Hepatic Dysfunction: Use with extreme caution and consider dose reduction or avoidance in severe hepatic impairment due to the risk of hepatotoxicity, especially with Nimesulide.
-
Patients with Comorbid Conditions: Use cautiously in patients with cardiovascular disease, diabetes, or gastrointestinal disorders. Individualized assessment is necessary.
Clinical Use Cases The provided sources focus on pain management and do not mention the drug combination in specialized clinical settings like intubation, surgical procedures, mechanical ventilation, or emergency situations.
Dosage Adjustments
Dosage adjustments are necessary for renal/hepatic impairment, certain comorbid conditions, and potential drug interactions. Consult regional or product-specific guidelines for detailed recommendations.
Side Effects
Common Side Effects:
Nausea, vomiting, diarrhea, dizziness, gastrointestinal discomfort (heartburn, indigestion), skin rash or itching, drowsiness.
Rare but Serious Side Effects:
Liver damage (hepatotoxicity), kidney problems, severe allergic reactions (anaphylaxis, angioedema, Stevens-Johnson syndrome), gastrointestinal bleeding.
Long-Term Effects:
Chronic kidney disease and gastrointestinal ulcers are potential complications of long-term use, particularly with NSAIDs.

Q4: What are the serious side effects to watch for with this combination?
A: Serious side effects include gastrointestinal bleeding, liver damage (hepatotoxicity), kidney problems, and allergic reactions. Immediate medical attention is required if these occur.
Q5: Can patients with a history of stomach ulcers take this medication?
A: No, it’s contraindicated in individuals with a history of peptic ulcers or gastrointestinal bleeding due to the increased risk of exacerbation.
Q6: How does magnesium trisilicate interact with other medications?
A: Magnesium trisilicate can affect the absorption of certain drugs. It’s important to inform your doctor about all medications being taken, including over-the-counter drugs and supplements.
Q7: Is it safe to consume alcohol while taking this combination?
A: No, alcohol should be avoided as it can increase the risk of side effects, particularly liver damage and gastrointestinal issues.
