Usage
This combination medication is primarily prescribed for the symptomatic relief of common cold and flu symptoms accompanied by fever, including headache, body aches, nasal congestion, runny nose, sneezing, and sore throat.
Pharmacological Classification: This combination product encompasses multiple pharmacological classes:
- Analgesic and Antipyretic: Paracetamol, Nimesulide
- Non-Steroidal Anti-Inflammatory Drug (NSAID): Nimesulide
- Antacid: Magnesium Trisilicate
- Antihistamine: Chlorpheniramine Maleate
Mechanism of Action:
- Paracetamol: Inhibits prostaglandin synthesis, reducing pain and fever. The exact mechanism is not fully understood.
- Nimesulide: A selective COX-2 inhibitor, decreasing inflammation, pain, and fever.
- Magnesium Trisilicate: Neutralizes gastric acid, providing relief from heartburn and indigestion, and potentially reducing NSAID-induced gastrointestinal side effects.
- Chlorpheniramine maleate: An H1 receptor antagonist, mitigating allergy symptoms like runny nose, sneezing, and watery eyes.
Alternate Names
How It Works
Pharmacodynamics:
- Paracetamol: Reduces pain and fever by inhibiting prostaglandin synthesis.
- Nimesulide: Exerts its anti-inflammatory, analgesic, and antipyretic effects through selective COX-2 inhibition.
- Magnesium Trisilicate: Neutralizes gastric acid.
- Chlorpheniramine maleate: Blocks H1 receptors, reducing histamine-mediated allergic reactions.
Pharmacokinetics: All components are absorbed orally. Metabolism primarily occurs in the liver, with excretion mainly through the kidneys. Nimesulide undergoes extensive hepatic metabolism, with CYP2C9 playing a major role. Paracetamol is metabolized through glucuronidation and sulfation pathways.
Mode of Action: The combination targets different pathways to provide comprehensive relief. Paracetamol and Nimesulide reduce pain and fever, while Magnesium Trisilicate addresses gastric discomfort, and Chlorpheniramine Maleate tackles allergy symptoms. Specific receptor binding, enzyme inhibition, or neurotransmitter modulation details for each component are outlined above.
Elimination Pathways: Primarily renal excretion, with some biliary excretion for Nimesulide.
Dosage
This specific combination is banned in several regions for children under 12. Dosage information is based on formulations where the individual components are available and permitted. Please always follow local regulations and consult with a specialist before prescribing or administering.
Standard Dosage
Adults: One tablet every 6-8 hours as needed. The maximum daily dose should not exceed the recommended limits for each individual component.
Children: Use is restricted or banned in children under 12 in many regions. Where permitted, dosing is typically weight-based and should be carefully determined by a physician. Pediatric safety considerations include close monitoring for adverse effects.
Special Cases:
- Elderly Patients: Start with a lower dose and titrate cautiously, monitoring renal and hepatic function.
- Patients with Renal Impairment: Dose adjustment is required based on creatinine clearance. Consult a nephrologist.
- Patients with Hepatic Dysfunction: Reduce the dose and monitor liver function tests closely. Consult a hepatologist.
- Patients with Comorbid Conditions: Careful assessment and dose adjustments may be necessary for patients with diabetes, cardiovascular disease, or other relevant conditions.
Clinical Use Cases
This combination drug isn’t typically used in clinical settings like intubation, surgical procedures, mechanical ventilation, ICU, or emergency situations. Its primary indication is symptomatic relief of cold and flu.
Dosage Adjustments
Dose modifications should be based on patient-specific factors like renal/hepatic impairment, metabolic disorders, or genetic polymorphisms affecting drug metabolism. Therapeutic drug monitoring may be helpful in some cases.

FAQs (Frequently Asked Questions)
Q1: What is the recommended dosage for Chlorpheniramine Maleate + Magnesium Trisilicate + Nimesulide + Paracetamol?
A: See “Dosage” section.
Q2: Is this combination safe for children?
A: In many regions, it’s banned or restricted in children under 12 years old due to safety concerns, particularly regarding nimesulide.
Q3: Can pregnant or breastfeeding women take this medication?
A: No, it is contraindicated in pregnancy and breastfeeding.
Q4: What should I do if a patient experiences adverse effects?
A: Discontinue the medication and consult a medical professional immediately. Provide supportive care based on symptoms.
Q5: Are there any alternatives to this combination?
A: Yes, individual components are available separately. Alternative analgesics, antipyretics, antacids, and antihistamines can be used depending on the patient’s specific needs. Consult with a physician or pharmacist to determine appropriate alternatives.
Q6: Does this combination interact with other medications?
A: Yes. See the “Drug Interactions” section. It’s crucial to review a patient’s full medication list before prescribing this medication.
Q7: How should I adjust the dosage for a patient with renal impairment?
A: Dosage adjustment is crucial in patients with renal impairment. Consult a nephrologist or refer to renal dosing guidelines for specific recommendations.
Q8: What is the role of Magnesium Trisilicate in this combination?
A: Magnesium Trisilicate acts as an antacid, neutralizing stomach acid to relieve heartburn and indigestion. It may also protect the stomach lining from potential NSAID-induced gastrointestinal irritation.
