The carcinogenic potential and reproductive toxicity of fexofenadine hydrochloride were assessed using terfenadine studies with adequate fexofenadine exposure area-under-the plasma concentration versus time curve [AUC]. The combination of terfenadine and pseudoephedrine hydrochloride in a ratio of 1: There are no adequate and well-controlled studies in pregnant women.
Nursing Mothers It is not known if fexofenadine is excreted in human milk. Because many drugs are excreted in human milk, caution should be used when fexofenadine hydrochloride is administered to a nursing woman.
Pseudoephedrine hydrochloride administered alone distributes into breast milk of lactating human females. Pseudoephedrine concentrations in milk are consistently higher than those in plasma. The fraction of a pseudoephedrine dose excreted in milk is estimated to be 0.
A decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Other reported clinical experience has not identified differences in responses between the elderly and younger subjects, although the elderly are more likely to have adverse reactions to sympathomimetic amines.
The pseudoephedrine component of ALLEGRA-D fexofenadine hcl and pseudoephedrine hcl 12 HOUR is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. However, dizziness, drowsiness, and dry mouth have been reported. Single doses of fexofenadine hydrochloride up to mg 6 healthy volunteers at this dose level , and doses up to mg twice daily for one month 3 healthy volunteers at this dose level , were administered without the development of clinically significant adverse events.
In large doses, sympathomimetics may give rise to giddiness, headache, nausea , vomiting, sweating , thirst, tachycardia , precordial pain, palpitations , difficulty in micturition , muscular weakness and tenseness, anxiety , restlessness, and insomnia. Many patients can present a toxic psychosis with delusions and hallucinations. Some may develop cardiac arrhythmias, circulatory collapse, convulsions, coma , and respiratory failure.
In the event of overdose, consider standard measures to remove any unabsorbed drug. Symptomatic and supportive treatment is recommended. Following administration of terfenadine, hemodialysis did not effectively remove fexofenadine, the major active metabolite of terfenadine, from blood up to 1.
The effect of hemodialysis on the removal of pseudoephedrine is unknown. It is also contraindicated in patients with severe hypertension, or severe coronary artery disease, and in those who have shown idiosyncrasy to its components, to adrenergic agents, or to other drugs of similar chemical structures. Manifestations of patient idiosyncrasy to adrenergic agents include: Fexofenadine hydrochloride inhibited antigen-induced bronchospasm in sensitized guinea pigs and histamine release from peritoneal mast cells in rats.
In laboratory animals, no anticholinergic or alpha1-adrenergic-receptor blocking effects were observed. Moreover, no sedative or other central nervous system effects were observed. Radiolabeled tissue distribution studies in rats indicated that fexofenadine does not cross the blood-brain barrier. The aqueous tablet film coating is made from hypromellose, iron oxide blends, polyethylene glycol, povidone, silicone dioxide, and titanium dioxide. Allegra ODT is formulated for disintegration in the mouth immediately following administration.
Each orally disintegrating tablet contains 30 mg fexofenadine hydrochloride and the following excipients: Allegra oral suspension, a white uniform suspension, contains 6 mg fexofenadine hydrochloride per mL and the following excipients: Allegra - Clinical Pharmacology Mechanism of Action Fexofenadine hydrochloride, the major active metabolite of terfenadine, is an antihistamine with selective H1-receptor antagonist activity.
Both enantiomers of fexofenadine hydrochloride displayed approximately equipotent antihistaminic effects. Fexofenadine hydrochloride inhibited antigen-induced bronchospasm in sensitized guinea pigs and histamine release from peritoneal mast cells in rats. The clinical significance of these findings is unknown. In laboratory animals, no anticholinergic or alpha1-adrenergic blocking effects were observed.
Moreover, no sedative or other central nervous system effects were observed. Radiolabeled tissue distribution studies in rats indicated that fexofenadine does not cross the blood-brain barrier. Pharmacodynamics Wheal and Flare. Human histamine skin wheal and flare studies in adults following single and twice daily doses of 20 and 40 mg fexofenadine hydrochloride demonstrated that the drug exhibits an antihistamine effect by 1 hour, achieves maximum effect at 2 to 3 hours, and an effect is still seen at 12 hours.
There was no evidence of tolerance to these effects after 28 days of dosing. Histamine skin wheal and flare studies in 7 to 12 year old subjects showed that following a single dose of 30 or 60 mg, antihistamine effect was observed at 1 hour and reached a maximum by 3 hours. No statistically significant increase in mean QTc interval compared to placebo was observed in adult subjects with seasonal allergic rhinitis given fexofenadine hydrochloride capsules in doses of 60 to mg twice daily for 2 weeks.
In addition, no statistically significant increase in mean QTc interval compared to placebo was observed in 40 healthy adult subjects given fexofenadine hydrochloride as an oral solution at doses up to mg twice daily for 6 days, or in healthy adult subjects given fexofenadine hydrochloride mg once daily for 1 year.
Pharmacokinetics The pharmacokinetics of fexofenadine hydrochloride in subjects with seasonal allergic rhinitis and subjects with chronic urticaria were similar to those in healthy subjects.
Fexofenadine hydrochloride was absorbed following oral administration of a single dose of two 60 mg capsules to healthy male subjects with a mean time to maximum plasma concentration occurring at 2. The tablet formulations are bioequivalent to the capsule when administered at equal doses.
Fexofenadine hydrochloride pharmacokinetics are linear for oral doses up to a total daily dose of mg mg twice daily. The administration of the 60 mg capsule contents mixed with applesauce did not have a significant effect on the pharmacokinetics of fexofenadine in adults. Fexofenadine hydrochloride was absorbed following single-dose oral administration of Allegra ODT 30 mg to healthy adult subjects with a mean time to maximum plasma concentration occurring at approximately 2.
After single-dose administration of Allegra 30 mg ODT to healthy adult subjects, the mean maximum plasma concentration Cmax was Allegra ODT 30 mg tablets are bioequivalent to the 30 mg Allegra tablets. Allegra ODT should be taken on an empty stomach. The bioavailability of Allegra ODT was comparable whether given with or without water [see Dosage and Administration 2.
A dose of 5 mL of Allegra oral suspension containing 30 mg of fexofenadine hydrochloride is bioequivalent to a 30 mg dose of Allegra tablets. The mean elimination half-life of fexofenadine was Because the absolute bioavailability of fexofenadine hydrochloride has not been established, it is unknown if the fecal component represents primarily unabsorbed drug or is the result of biliary excretion.
Pharmacokinetics in renally and hepatically impaired subjects and geriatric subjects, obtained after a single dose of 80 mg fexofenadine hydrochloride, were compared to those from healthy subjects in a separate study of similar design.
Based on increases in bioavailability and half-life, a dose of 60 mg once daily is recommended as the starting dose in adult patients with decreased renal function. For pediatric patients with decreased renal function, the recommended starting dose of fexofenadine is 30 mg once daily for patients 2 to 11 years of age and 15 mg once daily for patients 6 months to less than 2 years of age. The pharmacokinetics of fexofenadine hydrochloride in subjects with hepatic impairment did not differ substantially from that observed in healthy subjects.
Mean fexofenadine elimination half-lives were similar to those observed in younger subjects. A population pharmacokinetic analysis was performed with data from 77 pediatric subjects 6 months to 12 years of age with allergic rhinitis and adult subjects.
Across several trials, no clinically significant gender-related differences were observed in the pharmacokinetics of fexofenadine hydrochloride. In dogs, the plasma fexofenadine concentration was approximately 9 times the therapeutic plasma concentrations in adults receiving the maximum recommended human daily oral dose of mg.
In rabbits, the plasma fexofenadine concentration was approximately 20 times the therapeutic plasma concentration in adults receiving the maximum recommended human daily oral dose of mg. Unfortunately, due to the nature of the effect of the decongestant, they all work by constricting the vasculature, and if a patient happens to have high blood pressure, that is making things more difficult on the heart.
While the antihistamines by themselves will probably be acceptable, many people with allergies feel that it does not work as well. Please ask your physician to see if you are a candidate for topical nasal decongestant sprays as they won't cause a 'systemic' reaction as does the pseudoephedrine.
Also, speak with your physician about Singulair, as this works to attack allergies differently than Allegra.
