Usage
This combination medication is primarily used for the symptomatic relief of the common cold and flu. It addresses symptoms such as nasal congestion, runny nose, sneezing, itchy and watery eyes, headache, body aches, and fever. It can also be used to alleviate symptoms associated with allergies (allergic rhinitis) and sinusitis.
Pharmacological Classification: This is a combination product containing drugs from different classifications:
- Analgesic and Antipyretic: Paracetamol and Ibuprofen
- Antihistamine: Chlorpheniramine Maleate
- Decongestant: Phenylephrine
- Mineral supplement: Zinc
Mechanism of Action: Each component works through different mechanisms:
- Paracetamol: Inhibits prostaglandin synthesis in the central nervous system, reducing pain and fever.
- Ibuprofen: A non-steroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX) enzymes, reducing pain, fever, and inflammation.
- Chlorpheniramine Maleate: An H1 receptor antagonist that blocks the effects of histamine, a chemical mediator responsible for allergic symptoms.
- Phenylephrine: An alpha-1 adrenergic agonist that causes vasoconstriction in the nasal mucosa, reducing nasal congestion.
- Zinc: An essential mineral that supports immune function and may help reduce the duration and severity of cold symptoms.
Alternate Names
There is no internationally recognized non-proprietary name for this specific combination. Each ingredient, however, has its own recognized names:
- Paracetamol: Acetaminophen (USAN, primarily used in the United States)
- Chlorpheniramine maleate: Chlorphenamine maleate
Brand Names: One example of a brand name for a similar combination (containing paracetamol, phenylephrine, chlorpheniramine maleate, ibuprofen, and zinc) is Procold. Brand names can vary regionally.
How It Works
Pharmacodynamics:
- Paracetamol: Reduces fever by acting on the hypothalamic heat-regulating center and reduces pain by inhibiting prostaglandin synthesis.
- Ibuprofen: Reduces pain, fever, and inflammation by inhibiting COX-1 and COX-2 enzymes, thereby decreasing prostaglandin production.
- Chlorpheniramine: Competes with histamine for H1-receptor sites, thus reducing the effects of histamine release, like sneezing, itching, and runny nose.
- Phenylephrine: Stimulates alpha-adrenergic receptors in the nasal mucosa, causing vasoconstriction and reducing nasal congestion.
- Zinc: Modulates immune responses by affecting various immune cells and cytokines. It may also have antiviral properties.
Pharmacokinetics:
- Absorption: All components are generally well-absorbed orally.
- Metabolism: Paracetamol is primarily metabolized in the liver. Ibuprofen is also metabolized in the liver by CYP enzymes. Chlorpheniramine is extensively metabolized in the liver. Phenylephrine undergoes some first-pass metabolism. Zinc absorption is affected by dietary factors.
- Elimination: Paracetamol and ibuprofen metabolites are primarily excreted in the urine. Chlorpheniramine metabolites are also excreted in the urine. Phenylephrine is excreted in the urine primarily as sulfate conjugates. Zinc is primarily eliminated in the feces.
