Common Name

Diphenhydramine

Description

Diphenhydramine is a histamine H1 antagonist used as an antiemetic, antitussive, for dermatoses and pruritus, for hypersensitivity reactions, as a hypnotic, an antiparkinson, and as an ingredient in common cold preparations. It has some undesired antimuscarinic and sedative effects. -- Pubchem; Pseudoephedrine is a phenethylamine, and an isomer of ephedrine. Pseudoephedrine is the International Nonproprietary Name (INN) of the (1S,2S)- diastereomer of ephedrine (which has 1R,2S- configuration). Other names are (+)-pseudoephedrine and D-pseudoephedrine (Reynolds, 1989). The enantiomer (-)-(1R,2R)-Pseudoephedrine has fewer side-effects, fewer central nervous system (CNS) stimulatory effects, does not reduce to d-methamphetamine, yet retains its efficacy as a decongestant.[citation needed] However, the patent holder for (-)-Pseudoephedrine (Pfizer/Warner-Lambert) has not yet sought or received government approval for its sale to the public.(US Patent 6,495,529); Treatment for urinary incontinence is an unlabeled use for these medications. Unlabeled use means doctors can use the medication to treat a condition other than that for which it was first approved by the U.S. Food and Drug Administration (FDA). These medications are approved by the FDA for the treatment of nasal congestion caused by colds or allergies. However it has also been successful in treating stress incontinence by increasing the pressure (tension) exerted by the muscles of the bladder neck and the urethra, which helps retain the urine within the bladder. Despite being one of the oldest antihistamines on the market, it is by and large the most effective antihistamine available, either by prescription or over-the-counter, and has been shown to exceed the effectiveness of even the latest prescription drugs. Consequently, it is frequently used when an allergic reaction requires fast, effective reversal of the (often dangerous) effects of a massive histamine release. However, it is not always the drug of choice for treating allergies. Like many other first generation antihistamines, is also a potent anticholinergic agent. This leads to profound drowsiness as a very common side-effect, along with the possibilities of motor impairment (ataxia), dry mouth and throat, flushed skin, rapid or irregular heartbeat (tachycardia), blurred vision at near point due to lack of accommodation (cycloplegia), abnormal sensitivity to bright light (photophobia), pupil dilatation, urinary retention, constipation, difficulty concentrating, short-term memory loss, visual disturbances, hallucinations, confusion, erectile dysfunction, and delirium. -- Wikipedia ;.

Enzyme Details

1. Cytochrome P450 3A4

General function:: Involved in monooxygenase activity
Specific function:: Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1'-hydroxylation and midazolam 4-hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Acts as a 1,8-cineole 2-exo-monooxygenase. The enzyme also hydroxylates etoposide.
Gene Name:: CYP3A4
Uniprot ID:: P08684
Molecular weight:: 57255.585

2. Cytochrome P450 2D6

General function:: Involved in monooxygenase activity
Specific function:: Responsible for the metabolism of many drugs and environmental chemicals that it oxidizes. It is involved in the metabolism of drugs such as antiarrhythmics, adrenoceptor antagonists, and tricyclic antidepressants.
Gene Name:: CYP2D6
Uniprot ID:: P10635
Molecular weight:: 55768.94

Enzyme Details

3. Histamine H1 receptor

General function:: Involved in G-protein coupled receptor protein signaling pathway
Specific function:: In peripheral tissues, the H1 subclass of histamine receptors mediates the contraction of smooth muscles, increase in capillary permeability due to contraction of terminal venules, and catecholamine release from adrenal medulla, as well as mediating neurotransmission in the central nervous system
Gene Name:: HRH1
Uniprot ID:: P35367
Molecular weight:: 55783.6
