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.
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 ...
Normally, histamine acts on H 2 to stimulate acid secretion; drugs that inhibit H 2 signaling thus reduce the secretion of gastric acid. H 2-antihistamines are among first-line therapy to treat gastrointestinal conditions including peptic ulcers and gastroesophageal reflux disease. Some formulations are available over the counter.
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]
Benign paroxysmal positional vertigo (BPPV) is a disorder arising from a problem in the inner ear. [3] Symptoms are repeated, brief periods of vertigo with movement, characterized by a spinning sensation upon changes in the position of the head. [1]
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.
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 ...
The most common symptom of vestibular neuritis is the onset of vertigo that has formed from an ongoing infection or trauma. [9] The dizziness sensation that is associated with vertigo is thought to be from the inner ear labyrinth. [10] Rapid and undesired eye motion often results from the improper indication of rotational motion.
