OVERDOSAGE

Dizziness, drowsiness, dry mouth, and have been reported with fexofenadine hydrochloride overdose. Single doses of fexofenadine hydrochloride up to 800 mg (6 healthy subjects at this dose level), and doses up to 690 mg twice daily for 1 months (3 healthy subjects at this dose level ) or 240 mg once daily for 1 year (234 healthy subjects at this level of dose) were administered without the development of clinically significant adverse events compared to placebo. In case of overdose, examine the conventional methods to remove any unabsorbed drug. Symptomatic treatment and support is recommended. Following administration of terfenadine, hemodialysis did not have the effect of eliminating fexofenadine, the primary active metabolite of terfenadine, blood (up 1.7% withdrew). No deaths occurred at oral doses of fexofenadine hydrochloride up to 5000 mg / kg in mice (110 times the maximum recommended daily oral dose in adults and children based on mg/m2) and up to 5000 mg / kg in rats (230 timesthe maximum recommended daily oral dose in adults and 210 times the maximum recommended daily oral dose in children based on mg/m2). Furthermore, no clinical signs of toxicity or gross pathological were observed. In dogs, no evidence of oral toxicity was observed at doses up to 2000 mg / kg (300 times the maximum recommended daily oral dose in adults and 280 times the maximum recommended daily oral dose at the child is based on mg/m2). 11 DESCRIPTION Fexofenadine hydrochloride, the active ingredient pill Allegra, Allegra and Allegra ODT oral suspension, is a receptor of histamine H1-antagonist with the chemical name (±) -4-[1 hydroxy-4-[4 - (hydroxydiphenylmethyl) - 1-piperidinyl] Butyle] - α, α - dimethyl benzeneacetic acid hydrochloride. He has more of the chemical structure The molecular weight is 538.13 and the empirical formula is C32H39NO4 • HCl. Fexofenadine hydrochloride is a white to off-white crystalline powder. It is readily soluble in methanol and ethanol, sparingly soluble in chloroform and water, and insoluble in hexane. Fexofenadine hydrochloride is a racemate and exists as a zwitterion aqueous at physiological pH. Allegra is formulated as a tablet for oral administration. Each tablet contains 30, 60 or 180 mg of fexofenadine hydrochloride (depending on the dose strength) and excipients: croscarmellose sodium, magnesium stearate, microcrystalline cellulose, pregelatinized starch. The tablet aqueous film coating is made of hypromellose, iron oxide blends, polyethylene glycol, povidone, silicon dioxide, titanium dioxide. Allegra ODT is formulated decay in the mouth immediately after dosing. , Cream artificial flavor, and anhydrous alcohol; Alcohol is largely removed during the manufacturing process. Allegra oral suspension, a white uniform suspension, contains 6 mg of fexofenadine hydrochloride per mL and excipients: propylene glycol, edetate disodium, propylparaben, butylparaben, xanthan gum, poloxamer 407, titanium dioxide, sodium phosphate monobasic monohydrate, sodium phosphate dibasic heptahydrate, artificial raspberry cream flavor, sucrose, xylitol and purified water. 12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Fexofenadine hydrochloride, the primary active metabolite of terfenadine, an antihistamine is selective H1-receptor antagonist activity. Both enantiomers of fexofenadine hydrochloride posted approximately equipotent antihistamine effects. Fexofenadine hydrochloride inhibited antigen-induced bronchospasm in sensitized guinea pigs and release of histamine 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. Furthermore, no sedation or other effects on the central nervous system was observed. Radiomarqué tissue distribution studies in rats indicate that fexofenadine not to cross the blood-brain barrier. 12.2 Pharmacodynamics Wheal and Flare. Human histamine skin wheal and flare following studies in adults are single and twice daily doses of 20 and 40 mg of fexofenadine hydrochloride demonstrated that the drug presents an antihistamine effect by 1 hour, reaching a maximum effect at 2 to 3 hours, and the effect is still observed at 12 hours. There was no evidence of tolerance to the effects, after 28 days of treatment. The clinical significance of these findings is unknown. Histamine skin wheal and flare studies in 7 to 12 years has demonstrated that subjects following a single dose of 30 or 60 mg, the effects of antihistamines was observed at 1 hour and reached a maximum of 3 hours. Over 49% inhibition of wheal area, and 74% inhibition of the area have been maintained flare for 8 hours of the 30 and 60 mg. No statistically significant increase in the QTc interval on average compared to placebo was observed in 714 adult subjects with seasonal allergic rhinitis given fexofenadine hydrochloride capsules in doses of 60 to 240 mg twice daily for 2 weeks. Pediatric subjects of 2 placebo-controlled trials (N = 855) treated with a maximum of 60 mg of fexofenadine hydrochloride twice daily, no evidence of treatment or dose-related increases in QTc. In addition, no statistically significant increase in the QTc interval on average compared to placebo was observed in 40 healthy adult subjects given fexofenadine hydrochloride as an oral solution at doses up to 400 mg twice daily for 6 days, or in 230 healthy adult subjects given fexofenadine hydrochloride 240 Mg once a day for 1 year. In subjects with chronic idiopathic urticaria, there were no differences in any clinically relevant QTc intervals ECG including, among those treated with fexofenadine hydrochloride 180 mg once daily (n = 163) and those treated with a placebo (n = 91) during 4 weeks. 12.3 Pharmacokinetics The pharmacokinetics of fexofenadine hydrochloride in patients with seasonal allergic rhinitis and subjects with chronic urticaria were similar to those of healthy subjects. Absorption: Allegra tablets: Fexofenadine hydrochloride was absorbed after oral administration of a single dose of two 60 mg to healthy subjects male, with a mean time of maximum plasma concentration occurring at 2.6 hours after dosing. After administration of a single 60 mg capsules subjects healthy adults, the average maximum plasma concentration (Cmax) was 131 ng / mL. Following single dose oral administrations one of the 60 and 180 mg / day for adult males in good health, mean Cmax were 142 and 494 ng / mL, respectively. The tablets are bioequivalent to the capsule when administered at doses equal. Fexofenadine hydrochloride is linear pharmacokinetics of oral doses up to a total daily dose of 240 mg (120 mg twice daily). The administration of 60 mg capsule contents mixed with applesauce had no significant effect on the pharmacokinetics of fexofenadine in adults. The administration of 180 mg of fexofenadine hydrochloride tablets with a high fat meal reduced the average area under the curve (AUC) and (Cmax) of fexofenadine by 21 and 20% respectively. Allegra ODT: Fexofenadine hydrochloride was absorbed following a single dose of oral administration of Allegra ODT 30 mg in healthy subjects adults with a mean time to maximum plasma concentration occurring at approximately 2.0 hours after the dose. After a single dose administration of Allegra 30 mg ODT subjects healthy adults, the average maximum plasma concentration (Cmax) was 88.0 ng / mL. Allegra ODT 30 mg tablets are bioequivalent to the 30 mg Allegra tablets. The administration of Allegra ODT 30 mg with a high-fat meal has decreased the AUC and Cmax by approximately 40% and 60%, respectively, and 2 hours late in the exposure time peak (Tmax) been observed. 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 (2.2)] Allegra oral suspension: A dose of 5 mL of Allegra oral suspension containing 30 mg of fexofenadine hydrochloride is bioequivalent to 30 mg tablets Allegra. After oral administration of 30 mg of oral suspension for Allegra subjects healthy adults, the mean Cmax was 118 ng / mL and occurred at approximately 1 hour. The administration of 30 mg of Allegra oral suspension with a high fat meal reduced AUC and Cmax average of approximately 30 and 47%, respectively in healthy adult subjects. Distribution: Fexofenadine hydrochloride is 60% to 70% bound to plasma proteins, primarily albumin and α1-acid glycoprotein. Metabolism: Approximately 5% of the total dose of fexofenadine hydrochloride was eliminated by hepatic metabolism. Elimination: The mean elimination half-life of fexofenadine was 14.4 hours after administration of 60 mg twice daily to healthy subjects adults. Human mass balance studies documented a recovery of approximately 80% and 11% of the [14C] fexofenadine hydrochloride dose in the feces and urine, respectively. Because the absolute bioavailability of fexofenadine hydrochloride has not been established, it is not known if the fecal component primarily represents unabsorbed drug or is the result of biliary excretion. Special Populations: Pharmacokinetics in the liver and renal impaired geriatric topics and themes, obtained after a single dose of 80 mg of fexofenadine hydrochloride, were compared with those of healthy subjects in a separate study of similar design. Impaired renal: In subjects with mild to moderate (creatinine clearance 41-80 mL / min) and severe (creatinine clearance 11-40 mL / min) renal, peak plasma concentration of fexofenadine were 87% and 111% more, respectively, and the mean elimination half-life-were 59% Vies and 72% higher, respectively, than observed in healthy subjects. Peak plasma concentrations dialysis patients (creatinine clearance <10 n =" 14)" n =" 21)," n =" 1634)," n =" 863)," n =" 726)." n =" 259),">

6 REACTIONS
6.1 clinical studies of the experience Because clinical trials are conducted under different conditions, the rate of side effects seen in clinical trials of a drug can not be directly compared with the rate in clinical trials of another drug, and may not reflect the rates in practice. The safety data described below relate to exposure to fexofenadine hydrochloride 5083 patients in trials for allergic rhinitis and chronic idiopathic urticaria. In these trials, 3010 patients 12 years and older with seasonal allergic rhinitis were exposed to fexofenadine hydrochloride in doses of 20 to 240 mg twice daily or 120 to 180 mg once daily. A total of 646 patients 6 to 11 years of age with seasonal allergic rhinitis were exposed to fexofenadine hydrochloride at doses of 15 to 60 mg twice daily. The duration of treatment in these trials was 2 weeks. A total of 534 patients 6 months to 5 years, with allergic rhinitis have been exposed to fexofenadine hydrochloride at doses of 15 to 30 mg twice daily. The duration of treatment in these studies ranged from 1 day to 2 weeks. There were 893 patients 12 years and older with chronic idiopathic urticaria in fexofenadine hydrochloride exposed to doses of 20 to 240 mg twice daily or 180 mg once daily. The duration of treatment in these trials was 4 weeks. Seasonal allergic rhinitis Adults and teens: In placebo-controlled seasonal allergic rhinitis clinical trials on subjects 12 years and older, 2439 subjects received fexofenadine hydrochloride capsules in doses of 20 mg to 240 mg twice daily. All adverse events were reported by more than 1% of subjects who received the recommended daily dose of fexofenadine hydrochloride (60 mg twice daily) are listed in Table 1. In another placebo-controlled clinical study in the United States, 571 subjects aged 12 years and older has received fexofenadine hydrochloride tablets at doses of 120 or 180 mg once daily. Table 1 also lists the possible side effects that have been reported by more than 2% of subjects treated with fexofenadine hydrochloride tablets at a dose of 180 mg once daily. The incidence of side effects, including drowsiness and fatigue, was not dose-related and is similar across subgroups defined by age, sex and race.

In placebo-controlled chronic idiopathic urticaria clinical trials, 726 subjects 12 years and older has received fexofenadine hydrochloride tablets at doses of 20 to 240 mg twice daily. Table 4 lists the side effects in subjects aged 12 years and older who were reported by more than 2% of subjects treated with fexofenadine hydrochloride 60 mg twice daily in controlled clinical studies in the USA and Canada . In a placebo-controlled clinical study in the United States, 167 subjects aged 12 years and older has received fexofenadine hydrochloride 180 mg. Table 4 also lists the possible side effects that have been reported by more than 2% of subjects treated with fexofenadine hydrochloride tablets at a dose of 180 mg once daily.

Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to exposure to drugs. The events that have rarely been reported in post-marketing courses include: insomnia, nervousness, trouble sleeping or paroniria, and hypersensitivity reactions (including anaphylaxis, urticaria, angioedema, chest tightness, dyspnea, flushing , pruritus and rash). 7 Drug Interactions 7.1 Antacids Fexofenadine hydrochloride should not be taken in time closely with aluminum and magnesium-containing antacids. In subjects healthy adults, administration of 120 mg of fexofenadine hydrochloride (2 X 60 mg of the capsule) in the 15 minutes of aluminum and magnesium-containing antacids (Maalox) fell fexofenadine AUC by 41% and Cmax 43%. 7.2 Erythromycin and Ketoconazole Fexofenadine has been shown to exhibit minimal (about 5%) metabolism. However, the administration of fexofenadine hydrochloride or with ketoconazole or erythromycin resulted in increased plasma concentrations of fexofenadine in subjects healthy adults. Fexofenadine had no effect on the pharmacokinetics of a ketoconazole or erythromycin. In 2 separate studies subjects healthy adults, fexofenadine hydrochloride 120 mg twice daily (240 mg total daily dose) was co-administered with either erythromycin 500 mg every 8 hours or ketoconazole 400 mg once day under steady-state conditions in healthy subjects adults (N = 24, each study). No differences in adverse events or QTc interval was observed when subjects were administered fexofenadine hydrochloride alone or in combination either with ketoconazole or erythromycin. The results of these studies are summarized in the following table Table 5 Effects on the state of fexofenadine pharmacokinetics after 7 days of co-administration of fexofenadine hydrochloride 120 mg every 12 hours in healthy adult subjects (n = 24) concomitant drug CmaxSS (Pic plasma concentration) AUCss (0 to 12) (Measurement of systemic exposure) Erythromycin (500 mg every 8 hours) +82% +109% Ketoconazole (400 mg once daily) +135% +164% Changes in plasma levels were within the range of plasma levels achieved in adequate and well-controlled clinical trials. The mechanism of these interactions was assessed in vitro, in situ and in vivo animal models. These studies indicate that ketoconazole or erythromycin co improves fexofenadine gastrointestinal absorption. The observed increase in the bioavailability of fexofenadine may be due to effects related to transport, such as P-glycoprotein. In vivo animal studies also suggest that in addition to improving the uptake, ketoconazole secretion decreases fexofenadine gastrointestinal, while erythromycin may also reduce the biliary excretion. 7.3 Fruit juice Fruit juices, such as grapefruit, oranges and apples can reduce the bioavailability and exposure of fexofenadine. This is based on the results of 3 clinical studies using histamine-induced papules and rashes associated with a population pharmacokinetic analysis. The size of wheal and flare were significantly larger when fexofenadine hydrochloride was administered with either grapefruit or orange juice in relation to the water. Based on the reports of the literature, the same effects can be extrapolated to other fruit juices such as apple juice. The clinical significance of these findings is unknown. In addition, based on the population pharmacokinetic analysis of the combined data of grapefruit and orange juice with research data from a bioequivalence study, the bioavailability of fexofenadine was reduced by 36%. Therefore, in order to maximize the impact of fexofenadine, it is recommended that Allegra tablets should be taken with water [see Clinical Pharmacology (12.3) and Dosage and administration (2.1)]. ODT Allegra can be taken with or without water. (See Clinical Pharmacology (12.3) and Dosage and administration (2.2)]. 8 utilization in specific populations 8.1 Pregnancy Teratogenicity: Pregnancy Category C. There was no evidence of teratogenicity in rats or rabbits at oral doses of terfenadine up to 300 mg / kg, (which led to fexofenadine exposure were about 4 and 30 hours, respectively, the exhibition The maximum recommended daily oral dose of 180 mg of fexofenadine hydrochloride based on the comparison of AUCs). In mice, no adverse effects and no teratogenic effects were observed during gestation with fexofenadine hydrochloride oral doses up to 3730 mg / kg (which led to fexofenadine exposure, which were approximately 15 After exposure to the maximum recommended human daily oral dose of 180 mg of fexofenadine hydrochloride based on the comparison of AUCs). There are no adequate and well-controlled studies in pregnant women. Fexofenadine hydrochloride should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic effects: Dose linked to a small decrease in weight gain and survival were observed in rats exposed to an oral dose of 150 mg / kg of terfenadine (which led to fexofenadine exhibition, which were approximately 3 times exposure to the maximum recommended daily oral dose of 180 mg human of fexofenadine hydrochloride based on the comparison of AUCs). 8.3 Breastfeeding It is not known whether fexofenadine is excreted in human milk. There are no adequate and well-controlled studies in women during lactation. Because many drugs are excreted in human milk, caution should be exercised when fexofenadine hydrochloride is administered to a nursing woman. 8.4 Pediatric Use The recommended doses of fexofenadine hydrochloride in pediatrics 6 months to 11 years are based on studies comparing the pharmacokinetics of fexofenadine in adults and children on subjects and the safety profile of fexofenadine hydrochloride in both adults and children subjects at doses equal to or higher than the recommended doses.The safety and efficacy of fexofenadine hydrochloride in pediatrics under 6 months have not been established. The safety of fexofenadine hydrochloride is based on the administration of Allegra tablets at a dose of 30 mg twice daily demonstrated in 438 pediatric subjects 6 years to 11 years in 2 placebo-controlled for 2 weeks seasonal allergic rhinitis trial. The safety of fexofenadine hydrochloride at doses of 15mg and 30 mg once and twice daily was demonstrated in 969 pediatric subjects (6 months to 5 years) with allergic rhinitis in 3 pharmacokinetic studies and 3 of Security Studies. The safety of fexofenadine hydrochloride for the treatment of chronic idiopathic urticaria in patients 6 months to 11 years is based on studies comparing the pharmacokinetics of Allegra for adults and children on subjects and the safety profile of fexofenadine in both adult and pediatric subjects in doses equal to or greater than the recommended dose. The efficacy of fexofenadine hydrochloride for the treatment of seasonal allergic rhinitis in patients 6 to 11 years old, was demonstrated in 1 trial (N = 411) in which Allegra tablets 30 mg twice daily significantly reduced the symptoms by scores compared with placebo, and the extrapolation from the demonstrated effectiveness in subjects aged 12 years and older, comparisons and pharmacokinetics in adults and children. The efficacy of fexofenadine hydrochloride 30 mg twice daily for the treatment of seasonal allergic rhinitis in patients 2 to 5 years is based on comparisons of pharmacokinetics in adults and pediatric subjects and an extrapolation of evidence from the effectiveness of fexofenadine hydrochloride adult subjects with the state and the likelihood that the disease course, pathophysiology, and the influence of drugs are substantially similar in pediatric patients than in adult patients. The efficacy of fexofenadine hydrochloride for the treatment of chronic idiopathic urticaria in patients 6 months to 11 years is based on comparisons of pharmacokinetics in adults and children and an extrapolation of the effectiveness of Allegra demonstrated in adults with this disease and the probability that the disease, the pathophysiology and the effect of drugs are substantially the same among children than adult patients. Administration of 15 mg of fexofenadine hydrochloride Pediatric topics 6 months to less than 2 years and 30 mg for pediatric subjects 2 to 11 years of exposure produced comparable to those observed with a dose of 60 mg administered to adults. 8.5 Seniors Clinical studies of tablets and capsules Allegra did not include a sufficient number of subjects aged 65 years and older to determine if the population responds differently from younger subjects. Other reported clinical experience has not identified differences in responses between geriatrics and younger subjects. The drug is known to be substantially excreted by the kidneys and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because the elderly are more likely to have decreased renal function, care should be taken in choosing the dose, and it may be useful to monitor renal function [see Clinical Pharmacology (12.3)]. 8.6 renal Based on the increase in the bioavailability and half-life, a dose of 60 mg once a day is recommended that the starting dose in adult patients with decreased renal function (mild, moderate or severe renal insufficiency) . For pediatric patients with decreased renal function (mild, moderate or severe renal insufficiency), the recommended starting dose of fexofenadine is 30 mg once daily for patients 2 to 11 years and 15 mg once daily for patients 6 months to less than 2 years of age. [See Dosage and administration (2.2 and 2.3) and Clinical Pharmacology (12.3)] 8.7 liver The pharmacokinetics of fexofenadine hydrochloride in patients with hepatic impairment does not differ substantially from that observed in healthy subjects.
