Betahistine, sold under the brand name Serc among others, is an anti-vertigo medication. It is commonly prescribed for balance disorders or to alleviate vertigo symptoms . It was first registered in Europe in 1970 for the treatment of Ménière's disease, but current evidence does not support its efficacy in treating it.
A histamine agonist is a drug which causes increased activity at one or more of the four histamine receptor subtypes. H 1 agonists promote wakefulness. [1] H 2: Betazole and Impromidine are examples of agonists used in diagnostics to increase histamine. H 3: Betahistine is a weak Histamine 1 agonist and a very strong antagonist of the Histamine ...
An H 3 receptor antagonist is a type of antihistaminic drug used to block the action of histamine at H 3 receptors.. Unlike the H 1 and H 2 receptors which have primarily peripheral actions, but cause sedation if they are blocked in the brain, H 3 receptors are primarily found in the brain and are inhibitory autoreceptors located on histaminergic nerve terminals, which modulate the release of ...
Often, a specific cause is not identified. [3] When found, the underlying mechanism typically involves a small calcified otolith moving around loose in the inner ear. [3] Diagnosis is typically made when the Dix–Hallpike test results in nystagmus (a specific movement pattern of the eyes) and other possible causes have been ruled out. [1]
However, due to increased levels of drowsiness caused by the medication, it is generally of limited use in pilots and aircrew who must be dependably alert. [ 6 ] Additionally, cinnarizine can be used in scuba divers without an increased risk of central nervous system oxygen toxicity which can result in seizures, and is a high risk in closed ...
Ebastine is a H 1 antihistamine with low potential for causing drowsiness.. It does not penetrate the blood–brain barrier to a significant amount and thus combines an effective block of the H 1 receptor in peripheral tissue with a low incidence of central side effects, i.e. seldom causing sedation or drowsiness.
Betahistine at high doses (such as 144 mg/day) can yield similar vertigo control as intratympanic dexamethasone. [16] [17] Antivirals have been proven effective for those who suspect a viral cause for their cochlear Hydrops. [18] For some, surgery may be effective, such as an endolymphatic sac decompression. Surgery is often reserved for cases ...
Bilastine is an antihistamine medication used to treat hives (), allergic rhinitis and itchy inflamed eyes (allergic conjunctivitis) caused by an allergy. [6] It is a second-generation antihistamine and takes effect by selectively inhibiting the histamine H 1 receptor, preventing these allergic reactions. [7]
