The exercise is a form of habituation exercise, designed to allow the person to become accustomed to the position that causes the vertigo symptoms. The Brandt–Daroff exercises are performed in a similar fashion to the Semont maneuver; however, as the person rolls onto the unaffected side, the head is rotated toward the affected side.
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 ...

[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 ...
Some common side effects such as drowsiness, dry mouth, and tiredness may occur. Meclizine has been shown to have fewer dry mouth side effects than the traditional treatment for motion sickness, transdermal scopolamine.

Mepyramine rapidly permeates the brain, often causing drowsiness. [2] It is often sold as a maleate salt, pyrilamine maleate . The medication has negligible anticholinergic activity, with 130,000-fold selectivity for the histamine H 1 receptor over the muscarinic acetylcholine receptors (for comparison, diphenhydramine had 20-fold selectivity ...
