Identification
- Summary
Fexofenadine is a selective H1-antagonist for the symptomatic treatment of seasonal allergic rhinitis and chronic idiopathic urticaria.
- Brand Names
- Allegra, Allegra-D, Mucinex Non-drowsy Allergy, Wal-fex
- Generic Name
- Fexofenadine
- DrugBank Accession Number
- DB00950
- Background
Fexofenadine is an over-the-counter second-generation antihistamine used in the treatment of various allergic symptoms.10 It is selective for the H1 receptor, carries little-to-no activity at off-targets, and does not cross the blood-brain barrier9 - this is in contrast to previous first-generation antihistamines, such as diphenhydramine, which readily bind to off-targets that contribute to side effects such as sedation.1 Fexofenadine is the major active metabolite of terfenadine7 and is administered as a racemic mixture in which both enantiomers display approximately equivalent antihistamine activity.9

Pharmacology
- Indication
In the United States, fexofenadine is indicated for the symptomatic treatment of allergic rhinitis in patients ≥2 years old and chronic idiopathic urticaria in patients ≥6 months old.10 In Canada, fexofenadine carries the same indications but is approved only for patients ≥12 years old.9 Fexofenadine is also available in combination with pseudoephedrine for the symptomatic treatment of season allergic rhinitis in patients ≥12 years old.11

- Pharmacodynamics
Fexofenadine relieves allergy symptoms by antagonizing the actions of histamine, an endogenous compound predominantly responsible for allergic symptomatology.10 The relatively long duration of action of fexofenadine (approximately 24 hours)7 allows for once or twice daily dosing, and its rapid absorption allows for an onset of action within 1-3 hours. Fexofenadine should not be taken with fruit juice, as this may impair its absorption.10
- Mechanism of action
The H1 histamine receptor is responsible for mediating hypersensitivity and allergic reactions. Exposure to an allergen results in degranulation of mast cells and basophils, which then release histamine and other inflammatory mediators. Histamine binds to, and activates, H1 receptors, which results in the further release of pro-inflammatory cytokines, such as interleukins, from basophils and mast cells. These downstream effects of histamine binding are responsible for a wide variety of allergic symptoms, such as pruritus, rhinorrhea, and watery eyes.7
Fexofenadine is considered an “inverse agonist” of the H1 receptor because it binds to and stabilizes the inactive form of the receptor, preventing its activation and subsequent downstream effects.7 It has a potent and selective affinity for H1 receptors, and there is no evidence that it carries antidopaminergic, antiserotonergic, anticholinergic, sedative, or adrenergic blocking activity.9 Fexofenadine does not cross the blood-brain barrier and thus is unlikely to cause significant CNS effects.9
Target Actions Organism AHistamine H1 receptor antagonistHumans - Absorption
Fexofenadine is rapidly absorbed following oral administration and its absolute bioavailability is approximately 33%.9 The Tmax following oral administration is approximately 1-3 hours.9,7 The steady-state AUCss(0-12h) and Cmax following twice daily dosing of 60mg are 1367 ng/mL.h and 299 ng/mL, respectively.9
Fexofenadine AUC is decreased by >20% when coadministered with fruit juices (e.g. apple, orange, grapefruit) due to their inhibition of OATP transporters - for this reason, prescribing information recommends administering fexofenadine only with water.8 Similarly, coadministration of fexofenadine with a high-fat meal appears to decrease AUC and Cmax by >20%.10
- Volume of distribution
The volume of distribution is approximately 5.4-5.8 L/kg.7
- Protein binding
Fexofenadine is 60-70% bound to plasma proteins,10 primarily to albumin and α1-acid glycoprotein. The extent of protein binding is decreased to 56-68% and 56-75% in patients with renal and hepatic impairment, respectively.9
- Metabolism
Fexofenadine is very minimally metabolized, with only 5% of an ingested dose undergoing hepatic metabolism.10,7 The only identified metabolites are a methyl ester of fexofenadine (3.6% of the total dose) and MDL 4829 (1.5% of the total dose).9 The enzymes responsible for this metabolism have not been elucidated.

- Route of elimination
Approximately 80% of an ingested dose is eliminated in the feces, likely largely unchanged due to fexofenadine's limited metabolism, and 11% is eliminated in the urine.7 The principal pathways of fexofenadine elimination are biliary and renal.9
- Half-life
The terminal elimination half-life is approximately 11-15 hours.9,7
- Clearance
The oral clearance of fexofenadine is approximately 50.6 L/h and the renal clearance is approximately 4.32 L/h.9

- Toxicity
No deaths were observed following the oral administration of up to 5000 mg/kg in both mice and rats (equivalent to approximately 100-200x the recommended human dose). Single doses of up to 800 mg and chronic exposure of up to 690 mg twice daily for 1 month in humans did not result in clinically significant adverse events. Symptoms of overdosage are consistent with fexofenadine's adverse effect profile and are likely to include dizziness, drowsiness, and dry mouth.10
If overdosage occurs, employ symptomatic and supportive treatment. Hemodialysis does not effectively remove fexofenadine from the blood and is therefore of no benefit.10

- G-protein-coupled receptor for histamine, a biogenic amine that functions as an immune modulator and a neurotransmitter (PubMed:33828102, PubMed:8280179). Through the H1 receptor, histamine mediates the contraction of smooth muscles and increases capillary permeability due to contraction of terminal venules. Also mediates neurotransmission in the central nervous system and thereby regulates circadian rhythms, emotional and locomotor activities as well as cognitive functions (By similarity)

Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (By similarity). Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner (By similarity). The shared binding site between zinc and calcium at residue Asp-273 suggests a crosstalk between zinc and calcium transport in the blood (By similarity). The rank order of affinity is zinc > calcium > magnesium (By similarity). Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli from ferric transferrin, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli (PubMed:6234017). Does not prevent iron uptake by the bacterial siderophore aerobactin (PubMed:6234017)

Responsible for the transport of estrone 3-sulfate (E1S) through the basal membrane of syncytiotrophoblast, highlighting a potential role in the placental absorption of fetal-derived sulfated steroids including the steroid hormone precursor dehydroepiandrosterone sulfate (DHEA-S) (PubMed:11932330, PubMed:12409283). Also facilitates the uptake of sulfated steroids at the basal/sinusoidal membrane of hepatocytes, therefore accounting for the major part of organic anions clearance of liver (PubMed:11159893). Mediates the intestinal uptake of sulfated steroids (PubMed:12724351, PubMed:28408210). Mediates the uptake of the neurosteroids DHEA-S and pregnenolone sulfate (PregS) into the endothelial cells of the blood-brain barrier as the first step to enter the brain (PubMed:16908597, PubMed:25132355). Also plays a role in the reuptake of neuropeptides such as substance P/TAC1 and vasoactive intestinal peptide/VIP released from retinal neurons (PubMed:25132355). May act as a heme transporter that promotes cellular iron availability via heme oxygenase/HMOX2 and independently of TFRC (PubMed:35714613).

The exact transport mechanism has not been yet deciphered but most likely involves an anion exchange, coupling the cellular uptake of organic substrate with the efflux of an anionic compound (PubMed:19129463, PubMed:20507927, PubMed:26277985). Hydrogencarbonate/HCO3(-) acts as a probable counteranion that exchanges for organic anions (PubMed:19129463). Cytoplasmic glutamate may also act as counteranion in the placenta (PubMed:26277985). An inwardly directed proton gradient has also been proposed as the driving force of E1S uptake with a (H(+):E1S) stoichiometry of (1:1) (PubMed:20507927)
