Fexofenadine, sold under the brand name Allegra among others, [10] is an antihistamine pharmaceutical drug used in the treatment of allergy symptoms, such as hay fever and urticaria. [ 11 ] Therapeutically, fexofenadine is a selective peripheral H 1 blocker .

It contains fexofenadine, as the hydrochloride, an antihistamine; and pseudoephedrine, as the hydrochloride, a nasal decongestant. [2] In 2021, it was the 279th most commonly prescribed medication in the United States, with more than 800,000 prescriptions. [5] [6]
Upon study of records in mouse studies associated with 40 common medications ranging from antibiotics, antihistamines, aspirin, and hydrocortisone, that for subjects with melanoma and lung cancers, fexofenadine, one of three medications, along with loratadine, and cetirizine, that target histamine receptor H1 (HRH1), demonstrated significantly ...
The values below are standard apparent reduction potentials (E°') for electro-biochemical half-reactions measured at 25 °C, 1 atmosphere and a pH of 7 in aqueous solution. [ 1 ] [ 2 ] The actual physiological potential depends on the ratio of the reduced ( Red ) and oxidized ( Ox ) forms according to the Nernst equation and the thermal voltage .
Terfenadine acts as a peripherally-selective antihistamine, or antagonist of the histamine H 1 receptor. [3] It is a prodrug, generally completely metabolized to the active form fexofenadine in the liver by the enzyme cytochrome P450 3A4.
Cimetidine was the prototypical histamine H 2 receptor antagonist from which later drugs were developed. Cimetidine was the culmination of a project at Smith, Kline & French (SK&F; now GlaxoSmithKline) by James W. Black, C. Robin Ganellin, and others to develop a histamine receptor antagonist that would suppress stomach acid secretion.
Important reactions that result in hydrogen production start with glucose, which is converted to acetic acid: [1] C 6 H 12 O 6 + 2 H 2 O → 2 CH 3 CO 2 H + 2 CO 2 + 4 H 2. A related reaction gives formate instead of carbon dioxide: C 6 H 12 O 6 + 2 H 2 O → 2 CH 3 CO 2 H + 2 HCO 2 H + 2 H 2. These reactions are exergonic by 216 and 209 kcal ...
