[8] It is used in the treatment of itchiness, anxiety, insomnia, and nausea (including that due to motion sickness). [8] It is used either by mouth or injection into a muscle.

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 ...
