Fexofenadine + Pseudoephedrine
Indications
For the relief of symptoms associated with seasonal and perennial allergic complications in adults and children 12 years of age and older. Symptoms treated effectively include sneezing, rhinorrhea, itchy nose/ palate/ and/or throat, itchy/ watery/ red eyes, and nasal congestion.
It should be administered when both the antihistaminic properties of Fexofenadine Hydrochloride and the nasal decongestant properties of Pseudoephedrine Hydrochloride are desired.
Pharmacology
Fexofenadine Hydrochloride is an antihistamine with selective peripheral H1 receptor antagonist activity. It does not cross the blood brain barrier.
Pseudoephedrine is an orally active sympathomimetic amine and exerts a decongestant action on the nasal mucosa. This is recognized as an effective agent for the relief of nasal congestion due to allergic rhinitis.
Pseudoephedrine is both an α-and β-adrenergic receptor agonist. It causes vasoconstriction via direct stimulation of α-adrenergic receptors of the respiratory mucosa. It also directly stimulates β-adrenergic receptors causing bronchial relaxation, increased heart rate and contractility.
Dosage And Administration
The recommended dose is one tablet twice daily administered on an empty stomach with water for adults and children 12 years of age and older. It is recommended that the administration of this Tablet with food should be avoided.
One tablet once daily is recommended as the starting dose in patients with decreased renal function. This must be swallowed whole and never crushed or chewed.

Fexofenadine Hydrochloride and Pseudoephedrine Hydrochloride do not influence the pharmacokinetics of each other when administered concomitantly.
