Common NameFexofenadine
ClassSmall Molecule
DescriptionFexofenadine is an antihistamine drug used in the treatment of hayfever and similar allergy symptoms. It was developed as a successor of and alternative to terfenadine, an antihistamine with potentially fatal contraindications. Fexofenadine, like other second-generation antihistamines, does not readily enter the brain from the blood, and so causes less drowsiness than first generation histamine receptor antagonists; Fexofenadine hydrochloride (brand names include Allegra and Telfast) is an antihistamine drug used in the treatment of hayfever and similar allergy symptoms. It was developed as a successor of and alternative to terfenadine, an antihistamine with potentially fatal contraindications. Fexofenadine, like other second generation antihistamines, does not readily enter the brain from the blood, and so causes less drowsiness than first-generation histamine-receptor antagonists.

Toxicity Profile
Route of ExposureOral. 33%
Mechanism of ToxicityLike other H1-blockers, Fexofenadine competes with free histamine for binding at H1-receptors in the GI tract, large blood vessels, and bronchial smooth muscle. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms (eg. nasal congestion, watery eyes) brought on by histamine. Fexofenadine exhibits no anticholinergic, antidopaminergic, alpha1-adrenergic or beta-adrenergic-receptor blocking effects.
MetabolismApproximately 5% of the total dose is metabolized, by cytochrome P450 3A4 and by intestinal microflora. Half Life: 14.4 hours
Toxicity ValuesNot Available
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesAn antihistamine drug used in the treatment of hayfever and similar allergy symptoms.
Minimum Risk LevelNot Available
Health EffectsNot Available
SymptomsSide effects include dizziness, drowsiness, and dry mouth.
TreatmentIn the event of overdose, consider standard measures to remove any unabsorbed drug. Symptomatic and supportive treatment is recommended. (12)

2. Potassium voltage-gated channel subfamily H member 2
General Function:
Voltage-gated potassium channel activity involved in ventricular cardiac muscle cell action potential repolarization
Specific Function:
Pore-forming (alpha) subunit of voltage-gated inwardly rectifying potassium channel. Channel properties are modulated by cAMP and subunit assembly. Mediates the rapidly activating component of the delayed rectifying potassium current in heart (IKr). Isoforms USO have no channel activity by themself, but modulates channel characteristics by forming heterotetramers with other isoforms which are retained intracellularly and undergo ubiquitin-dependent degradation.
