Histamine preparation

Pharmacological Action

Synthetic analogue of histamine. It acts similarly to histamine, mainly on histamine H₁ receptors.

It causes dilation of precapillaries, in particular, facilitates microcirculation in the labyrinth.

Furthermore, Betahistine regulates endolymph pressure in the labyrinth and cochlea, leading to clinical improvement in vertigo of various etiologies.

It reduces the frequency and intensity of vertigo, reduces tinnitus, and contributes to hearing improvement in cases of its decline.

It increases the tone of the smooth muscles of the bronchi and gastrointestinal tract.

It may cause increased gastric juice secretion.

Pharmacokinetics

After oral administration, betahistine dihydrochloride is rapidly and almost completely absorbed from the gastrointestinal tract.

Plasma protein binding is low.

It is almost completely eliminated from the body with urine within 24 hours.

T_1/2 is 3-4 hours.
