PharmacodynamicsCetirizine acts as a highly selective antagonist of histamine H1 receptors. [3] The Ki values for the H1 receptor are approximately 6 nM for cetirizine, approximately 3 nM for levocetirizine, and approximately 100 nM for dexetirizine, indicating that the levo-enantiomer is the predom

Cetirizine, sold under the brand name Zyrtec among others, is a second-generation antihistamine used to treat allergic rhinitis (hay fever), dermatitis, and hives (hives). [5] It is taken orally. [6] Effects usually start within thirty minutes and last for about a day. [6] The degree of benefit is s

Azelastine, marketed under brands such as Optivar, is an H1 receptor blocking drug used primarily as a nasal spray to treat allergic rhinitis (hay fever) and as an eye drop to treat allergic conjunctivitis. [4][5] Other uses may include oral treatment of asthma and rashes. [6] Effects appear within

Sodium salicylate is the sodium salt of salicylic acid. It can be prepared by sodium phenate and carbon dioxide at higher temperature and pressure. Historically, it was synthesized by refluxing methyl salicylate (oil of wintergreen) with excess sodium hydroxide. characteristic:Sodium salicylate belo

Reactions with electrophilesNaphthalene reacts more readily than benzene in electrophilic aromatic substitution reactions. For example, the chlorination and bromination of naphthalene proceed without catalysts to 1-chloronaphthalene and 1-bromonaphthalene, respectively. Likewise, while both benzene

Camphorquinone, also known as 2,3-camphoranedione, is an organic compound extracted from camphor. A yellow solid used as a photoinitiator for curing dental composites.

Azetidine is a saturated heterocyclic organic compound containing three carbon atoms and one nitrogen atom. It is liquid at room temperature, has a strong ammonia odor, and is strongly basic compared with most secondary amines.synthesis and generationAzetidines can be prepared by reducing azetidinon

Quinoline is a heterocyclic aromatic organic compound with the chemical formula C9H7N. A colorless hygroscopic liquid with a strong odour. Aged samples, especially if exposed to light, turn yellow and then brown. Quinoline is only slightly soluble in cold water, but readily soluble in hot water and
