Usage
This combination medication is primarily prescribed for the symptomatic relief of the common cold and flu. It addresses multiple symptoms concurrently, including fever, headache, body aches, nasal congestion, and runny nose. It’s pharmacological classifications include:
- Analgesic: Paracetamol and Nimesulide provide pain relief.
- Antipyretic: Paracetamol reduces fever.
- Anti-inflammatory: Nimesulide reduces inflammation.
- Decongestant: Phenylephrine relieves nasal congestion.
- Stimulant: Caffeine counteracts the drowsiness caused by some antihistamines often included in similar formulations (though not in this particular combination).
Mechanism of Action: This combination works through the synergistic action of its components. Paracetamol inhibits prostaglandin synthesis, reducing pain and fever. Nimesulide, an NSAID, also inhibits prostaglandins, further contributing to pain and inflammation reduction. Phenylephrine constricts blood vessels in the nasal passages, relieving congestion. Caffeine acts as a central nervous system stimulant.
Alternate Names
There are no officially recognized alternate names for this specific four-drug combination. However, different pharmaceutical companies market this combination under various brand names. Some examples are “Coldinix N” and others mentioned in the sources provided. It is crucial to note that formulations containing cetirizine in addition to these four components are also available and discussed within the sources. However, this section specifically addresses the combination of only caffeine, nimesulide, paracetamol, and phenylephrine.
How It Works
Pharmacodynamics: Paracetamol and Nimesulide exert their analgesic and antipyretic effects through the inhibition of prostaglandin synthesis. Phenylephrine acts as an α1-adrenergic receptor agonist, causing vasoconstriction in the nasal mucosa, which reduces swelling and congestion. Caffeine stimulates the central nervous system, increasing alertness and counteracting drowsiness.
Pharmacokinetics:
- Absorption: All components are absorbed relatively well from the gastrointestinal tract.
- Metabolism: Paracetamol, nimesulide, and caffeine are primarily metabolized in the liver. Phenylephrine undergoes first-pass metabolism.
- Elimination: The metabolites of these drugs are primarily excreted through the kidneys.
Dosage
Dosage information for this specific combination is limited in the sources, but general guidelines can be inferred:
Standard Dosage
Adults: The usual recommended dose for adults is one tablet every 6-8 hours as needed. It’s always essential to follow the prescribed dosage.
Special Cases: Dosage adjustments should be made in elderly patients and those with renal or hepatic impairment. It is important to always consult a physician for appropriate dosage adjustments.
Clinical Use Cases
The use of this specific combination in specific clinical settings like intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations, is not well-documented. It is primarily intended for the relief of common cold and flu symptoms in an outpatient setting.
Dosage Adjustments

Side Effects
Common Side Effects:
Nausea, vomiting, diarrhea, fatigue, drowsiness, dry mouth, headache, dizziness.
Rare but Serious Side Effects:
Allergic reactions (e.g., skin rash, itching, swelling of the face, lips, or tongue), liver damage (with excessive paracetamol use), cardiovascular events (with phenylephrine, especially in patients with pre-existing conditions).
Long-Term Effects:
Chronic use of Nimesulide is associated with potential gastrointestinal and renal complications.
Contraindications
