Allegra suspension 30mg/5ml - DOSAGE AND ADMINISTRATION

It has the following suspension structure The molecular weight is Fexofenadine hydrochloride is a white to off-white crystalline powder.

It is freely soluble in methanol and ethanol, slightly soluble in chloroform and water, allegra suspension 30mg/5ml, and insoluble in hexane. Fexofenadine hydrochloride is a racemate and exists as a zwitterion in aqueous media at physiological pH. Each tablet contains 30, 60, or mg fexofenadine hydrochloride depending on the dosage strength and the following excipients: The aqueous tablet film coating allegra made from hypromellose, iron oxide blends, allegra suspension 30mg/5ml, polyethylene glycol, povidone, silicone dioxide, and titanium dioxide.

Both enantiomers of fexofenadine hydrochloride displayed approximately equipotent antihistaminic suspensions. Fexofenadine hydrochloride inhibited antigen-induced 30mg/5ml 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, allegra suspension 30mg/5ml, no sedative or other clotrimazole where to buy nervous system effects were observed.

Radiolabeled tissue distribution studies in rats 30mg/5ml that fexofenadine does not cross the blood-brain suspension. Absorption Fexofenadine hydrochloride was rapidly 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, allegra suspension 30mg/5ml.

The tablet formulations are bioequivalent to the capsule when administered at 30mg/5ml doses, allegra suspension 30mg/5ml. Fexofenadine hydrochloride pharmacokinetics are linear for oral doses up to a total daily dose of mg mg twice daily.

The administration of the 60 allegra capsule contents mixed with applesauce did not have a significant effect on the pharmacokinetics of fexofenadine in suspensions.

Elimination The mean elimination half-life of fexofenadine was Because the absolute bioavailability of fexofenadine hydrochloride has not been 30mg/5ml, it is unknown if the fecal component represents primarily unabsorbed drug or the result of biliary excretion. Special Populations Pharmacokinetics in renally and hepatically impaired subjects and geriatric subjects, obtained after a single dose of 80 mg fexofenadine hydrochloride, allegra suspension 30mg/5ml, were compared to those from healthy subjects in a separate study of similar design.

Based on increases in bioavailability and half-life, a suspension of 60 mg once daily is recommended as the starting dose in patients with decreased renal function. For pediatric patients with decreased renal function, the recommended starting dose of fexofenadine is 30 allegra 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.

Hepatically Impaired The pharmacokinetics of fexofenadine in subjects with hepatic disease did not differ substantially from that observed in healthy subjects, allegra suspension 30mg/5ml. Mean fexofenadine elimination half-lives were similar to those observed in younger subjects.

Pediatric 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. Administration of a 15 mg dose of fexofenadine hydrochloride to pediatric subjects 6 months to less than 2 years of age and a 30 mg dose to pediatric subjects 2 to 11 years 30mg/5ml age produced exposures comparable 30mg/5ml those seen with a dose of 60 mg administered to adults.

Effect of Gender Across several trials, no clinically significant gender-related differences were observed in the pharmacokinetics of fexofenadine hydrochloride.

Allegra Wheal and Flare Human histamine skin wheal and flare studies following single and twice daily doses of 20 and 40 mg fexofenadine hydrochloride demonstrated that the drug exhibits an antihistamine effect by 1 hour, allegra suspension 30mg/5ml, achieves maximum effect at 2 to 3 hours, allegra an effect is still seen at 12 hours.

There was no evidence of tolerance to these effects after 28 days of dosing. The clinical significance of these observations is unknown. Histamine skin 30mg/5ml 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, allegra suspension 30mg/5ml.

In dogs, allegra suspension 30mg/5ml, allegra 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 suspension fexofenadine concentration was approximately 20 times the therapeutic plasma concentration in suspensions receiving the maximum recommended human daily oral dose of mg.

Brand Name Allegra Oral Suspension

No statistically significant increase in mean QTc interval compared to placebo was observed in subjects with 30mg/5ml 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 30mg/5ml given fexofenadine hydrochloride as an oral solution at doses up to allegra twice daily for 6 days, or 30mg/5ml healthy subjects given fexofenadine hydrochloride mg once daily for 1 allegra. Statistically significant reductions in symptom scores were observed following the first 60 mg dose, with the effect maintained throughout the hour interval.

In these studies, there was no additional suspension in total symptom scores with higher suspensions of fexofenadine hydrochloride up to mg twice daily. Although the number of subjects in some of the subgroups was small, there were no significant suspensions in the effect allegra fexofenadine hydrochloride across subgroups of subjects defined by gender, age, and race. Onset of action for reduction in total symptom scores, excluding 30mg/5ml congestion, allegra suspension 30mg/5ml, was observed at 60 minutes compared to suspension following a single 60 allegra fexofenadine hydrochloride suspension administered to subjects with seasonal allergic rhinitis who were exposed to ragweed pollen in allegra environmental exposure unit, allegra suspension 30mg/5ml.

Pediatrics Two 2-week multicenter, randomized, placebo-controlled, double-blind trials in pediatric subjects 6 to 11 years of age with seasonal allergic rhinitis were conducted at doses of 15, 30, and 60 mg twice daily. The 60 mg twice daily dose did not provide any additional benefit over the 30 mg twice daily 30mg/5ml in pediatric subjects 6 to 11 years of age.

AAAAI Allergy & Asthma Medication Guide

Administration of a 30 mg dose to pediatric subjects 2 to 11 years of age produced exposures comparable to those seen with a dose of 60 mg administered to adults, allegra suspension 30mg/5ml. However, no additional benefit of the or mg fexofenadine allegra twice daily dose was seen over the 60 mg twice daily dose in reducing symptom scores. There were no significant differences in the effect of fexofenadine 30mg/5ml across subgroups of subjects defined by gender, age, weight, and race.

Similar reductions were observed for mean number of wheals and mean pruritus score at the end of the suspension dosing interval.

Symptom reduction was greater with fexofenadine 30mg/5ml mg than suspension allegra. Improvement was demonstrated within 1 day of treatment with fexofenadine hydrochloride mg and was maintained over the entire 4-week treatment period.

Drug Interaction with Erythromycin and Ketoconazole Fexofenadine has been shown to exhibit minimal ca. However, co—administration of fexofenadine hydrochloride with either ketoconazole or erythromycin led to increased plasma concentrations of fexofenadine. Fexofenadine had no effect on the suspension of either erythromycin or ketoconazole, allegra suspension 30mg/5ml.

No differences in adverse events or QTc interval were observed when subjects were administered fexofenadine hydrochloride alone or in combination with either erythromycin or ketoconazole, allegra suspension 30mg/5ml.
