Adverse Effects
Side effects of Caffeine + Chlorpheniramine + Paracetamol + Phenylephrine :
Generally well tolerated and adverse events are rare.
Hypersensitive individuals may display ephedrine-like reactions such as tachycardia, palpitations, headache, dizziness and nausea. Use of sympathomimetics has been associated with fear, anxiety, restlessness, tremor, weakness, dysuria, insomnia, hallucinations and convulsions. Chlorpheniramine in may cause sedation.
Mechanism of Action
Paracetamol produces analgesia by elevation of the pain threshold and antipyretic effect through action on the hypothalamic heat-regulating center.
Paracetamol
is equal to aspirin in analgesic and antipyretic effectiveness, and it is
unlikely to produce many of the side effects associated with aspirin and aspirin-containing products.
Sympathomimetic decongestants reduce the nasal congestion due to increased nasal blood flow associated with colds and influenza.
Phenylephrine is sympathomimetic vasoconstrictor that has been used as a decongestant. It is a relatively selective alpha-adrenoceptor agonist. The majority of the sympathomimetic action is due to direct stimulation of the adrenoceptors and relatively little is due to an indirect effect via release of noradrenaline. Its pressor action is weaker than that of noradrenaline but of longer duration. At therapeutic doses, it does not cause significant stimulation of the central nervous system.
Chlorpheniramine provides prompt relief of itchy-watery eyes, runny nose, sneezing, itching of the nose or throat due to respiratory allergies.
Caffeine enhances the analgesic activity of Paracetamol and serves to reduce incidence of sedation due to Chlorpheniramine maleate.
The Sodium citrate liquefies mucus and helps expectoration whereas Menthol has a cooling and soothing effect.
