Coricidin, Coricidin 'D' (decongestant), or Coricidin HBP (for high blood pressure), is the name of an over-the-counter cough and cold drug containing dextromethorphan (a cough suppressant) and chlorpheniramine maleate (an antihistamine). [1] Introduced by Schering-Plough in 1949 as one of the first antihistamines, it is now owned by Bayer.
It is a first-generation antihistamine and works by blocking the histamine H 1 receptor. [2] Common side effects include sleepiness, restlessness, and weakness. Other side effects may include dry mouth and wheeziness. [2] Chlorpheniramine was patented in 1948 and came into medical use in 1949. [3] It is available as a generic medication and ...
Pheniramine (trade name Avil among others) is an antihistamine with anticholinergic properties used to treat allergic conditions such as hay fever or urticaria.It has relatively strong sedative effects, and may sometimes be used off-label as an over-the-counter sleeping pill in a similar manner to other sedating antihistamines such as diphenhydramine.
It also contains 237 million bioactivity test results from 1.25 million biological assays, covering >10,000 target protein sequences. [ 4 ] As of 2020, with data integration from over 100 new sources, PubChem contains more than 293 million depositor-provided substance descriptions, 111 million unique chemical structures, and 271 million ...
Dexchlorpheniramine is an antihistamine, or an antagonist of the histamine H 1 receptor. A study found that dexchlorpheniramine had a K i value of 20 to 30 μM for the muscarinic acetylcholine receptors using rat brain tissue. [4]
Coricidin, Coricidin D, or Coricidin HBP, is the brand name of a combination of dextromethorphan and chlorpheniramine maleate (an antihistamine). [citation needed] Varieties may also contain acetaminophen and guaifenesin. [citation needed] Codral is a brand name manufactured by Johnson & Johnson and sold primarily in Australia and New Zealand ...
The halogenated alkylamine antihistamines all exhibit optical isomerism; brompheniramine products contain racemic brompheniramine maleate, whereas dexbrompheniramine (Drixoral) is the dextrorotary (right-handed) stereoisomer. [2] [8] Brompheniramine is an analog of chlorpheniramine. The only difference is that the chlorine atom in the benzene ...
Chloropyramine is known as a competitive reversible H 1 receptor antagonist (also known as an H 1 inverse agonist), meaning that it exerts its pharmacological action by competing with histamine for the H 1 subtype histamine receptor. By blocking the effects of histamine, the drug inhibits the vasodilation, increased vascular permeability, and ...
