View Dimenhydrinate Sunward description for details of the chemical structure and excipients (inactive components). Diphenhydramine is an antihistamine mainly used to treat allergies. Dimenhydrinate, a synthetic drug introduced into medicine in 1949, is administered orally in tablet or syrup form. METHOD The action of dimenhydrinate on vestibular function was investigated by means of the cold microcaloric test 8 and galvanic stimulation of the mastoid area. Dimenhydrinate, an anti-nauseant/antiemetic, is the 8-chlorotheophylline salt of diphenhydramine. The risk or severity of QTc prolongation can be increased when Adenosine is combined with Dimenhydrinate. Dimenhydrinate may impair the ability to perform hazardous activities requiring mental alertness or physical coordination such as operating machinery or driving a car. Dimenhydrinate is an antiemetics drug combination that contains diphenhydramine and theophylline. Dimenhydrinate's anti-emetic effect is probably due to H1 antagonism in the vestibular system in the brain. ; U.S. Patent 2,499,058; February 28,1950; assigned to G.D. Searle & Co. 70% to 85% (Gravol Canadian labeling 2016) Use: Labeled Indications Diphenhydramine and dimenhydinate both reduce vestibular neuronal excitation due to angular or linear acceleration motions. This information should not be interpreted without the help of a healthcare provider. Structure. Antihistamines appear to compete with histamine for cell receptor sites on effector cells. The main difference relative to pure diphenhydramine is a lower potency due to being combined with 8-chlorotheophylline. Dimenhydrinate inhibits vomiting by affecting the histaminic receptor and cholinergic receptor function center of vestibular nucleus in the central vestibular system. Nausea, vomiting, dizziness associated with motion sickness,…. Toxicology also manifests in the autonomic nervous system, primarily at the neuromuscular junction, resulting in ataxia and extrapyramidal side effects and the feeling of heaviness in the legs, and at sympathetic post-ganglionic junctions, causing urinary retention, pupil dilation, tachycardia, irregular urination, and dry red skin caused by decreased exocrine gland secretions, and mucous membranes. By weight, dimenhydrinate is between 53% to 55.5% diphenhydramine. Mechanism of Action Competes with histamine for H 1 -receptor sites on effector cells in the gastrointestinal tract, blood vessels, and respiratory tract; blocks chemoreceptor trigger zone, diminishes vestibular stimulation, and depresses labyrinthine function through its central anticholinergic activity In addition, they prevent histamine from binding and stimulating the cells. dimenhydrinate indications. Although their mechanism of action is not well understood, it is believed that these drugs act by blocking muscarinic receptors in the brain rather than by the blockade of central histamine receptors. DIMENHYDRINATE INJECTION USP AND SANDOZ DIMENHYDRINATE ARE NOT INTENDED FOR PROLONGED USE EXCEPT ON THE ADVICE OF A PHYSICIAN. The risk or severity of adverse effects can be increased when Dimenhydrinate is combined with Acetophenazine. 1951 Jul-Sep;14(3):325-31. Dimenhydrinate directly inhibits the stimulation of certain nerves in the brain and inner ear to suppress nausea, vomiting, dizziness, and vertigo. Mechanism of action of Dimenhydrinate : Dimenhydrinate Is An Antihistamine Which Also Has Antimuscarinic And Central Sedative Action. Neurosci Biobehav Rev. Dimenhydrinate directly inhibits the stimulation of certain nerves in the brain and inner ear to suppress nausea, vomiting, dizziness, and vertigo. Dimenhydrinate is a combination drug of diphenhydramine and 8-Chlorotheophylline.[1]. antiemetic, antivertigo, antihistamine. 2 Several reports have appeared attesting to its value in radiation sickness, 3 nausea and vomiting of pregnancy, 4 Ménière's syndrome, 5 vestibular reactions … A review.
