Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.
Guaifenesin overdose: nausea and vomiting.
Pseudoephedrine overdose: Bradycardia, palpitation, tachycardia, nausea, vomiting, convulsion (seizure), dizziness, tremor, agitation, anxiety, insomnia, irritability, nervousness, restlessness, hypertension, increased blood pressure.
Treatment: Appropriate supportive therapy dependent upon individual response to the preparation.
Pharmacotherapeutic group: Expectorant
ATC code: RO5CAO3
Guaifenesin has an expectorant action which increases the output of respiratory tract fluid by reducing adhesiveness and surface tension. The increased flow of less viscid secretion promotes ciliary action and facilitates the removal of mucus. This changes a dry unproductive cough to a cough that is more productive and less frequent.
Pharmacotherapeutic group: Sympathomimetic
ATC code: R01BA02
Pseudoephedrine is a stereoisomer of ephedrine and has a similar action, but has been stated to have less pressor activity and central nervous system effects.
It is a sympathomimetic agent with indirect and direct effects on adrenergic receptors and is an orally effective upper respiratory tract decongestant. It has alpha- and beta-Adrenergic activity and has pronounced stimulating effects on the central nervous system. In therapeutic doses it raises the blood pressure by increasing cardiac output and also by inducing peripheral vasoconstriction.
Guaifenesin is well absorbed from the gastro intestinal tract following oral administration. Guaifenesin has a plasma half-life of approximately 1 hour. It is rapidly hydrolyzed (60% within seven hours) and then excreted in the urine, with beta-(2-methoxyphenoxy)-lactic acid as its major urinary metabolite.
Pseudoephedrine is absorbed from the gastro-intestinal tract. It is resistant to metabolism by monoamine oxidase and is largely excreted unchanged (55-75%) in the urine together with small amounts of its hepatic metabolite. It has a half-life of several hours; elimination is enhanced and half-life accordingly shorter in acid urine.
