🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionBetahistine is rapidly and almost completely absorbed from the gastrointestinal tract after oral administration. However, it undergoes extensive first-pass metabolism in the liver, which reduces its systemic bioavailability.
DistributionBetahistine is widely distributed throughout the body. It crosses the blood-brain barrier and reaches the inner ear. The volume of distribution is not well established from the available information.
Protein BindingBetahistine has very low protein binding, reported to be less than 5%.
MetabolismBetahistine is extensively metabolised in the liver, primarily by monoamine oxidase (MAO) enzymes, to form inactive metabolites including 2-pyridylacetic acid and aminoethylpyridine. The first-pass effect is significant.
Half-LifeThe elimination half-life of betahistine is approximately 3 to 4 hours. The half-life of its main metabolite, 2-pyridylacetic acid, is about 3.5 hours.
ExcretionBetahistine and its metabolites are excreted primarily in the urine. About 80-90% of a dose is recovered in urine as metabolites, with a small amount excreted in faeces.
BioavailabilityThe oral bioavailability of betahistine is very low, estimated to be less than 1% due to extensive first-pass metabolism. This is why higher oral doses are often used compared to other routes.
Onset of ActionThe onset of action for symptom relief is not immediate. It may take several days to weeks of regular use before a noticeable improvement in vertigo occurs.
Peak Plasma TimePeak plasma concentration of betahistine is reached approximately 1 hour after oral administration. The main metabolite, 2-pyridylacetic acid, peaks at about 1 hour.
Duration of ActionThe duration of action is not precisely established, but the effects on vertigo control are maintained with regular dosing. Symptom relief may last for several hours after each dose, but the full benefit requires consistent use.

How It Works

This medicine works by acting as a partial agonist at histamine H1 receptors and as an antagonist at histamine H3 receptors in the inner ear and central nervous system. By stimulating H1 receptors, it helps to dilate blood vessels in the inner ear, improving blood flow and reducing fluid pressure. At the same time, blocking H3 receptors increases the release of histamine and other neurotransmitters, which further supports improved circulation and reduces the abnormal signals that cause vertigo. This dual action helps to stabilise the balance mechanism and alleviate symptoms such as dizziness, spinning, and ringing in the ears.

Mechanism Steps

1
Partial agonist at H1 receptors: This medicine binds to and partially activates histamine H1 receptors in the inner ear blood vessels, leading to vasodilation and increased blood flow.
2
Antagonist at H3 receptors: It blocks histamine H3 receptors, which normally inhibit histamine release. This blockade increases the release of histamine and other neurotransmitters, further enhancing blood flow and reducing vestibular signals.
3
Reduction of endolymphatic pressure: Improved blood flow and altered fluid dynamics in the inner ear help to reduce the pressure of endolymph, which is a key factor in Meniere's disease and other vestibular disorders.
4
Stabilisation of vestibular system: The combined effects on blood flow and neurotransmitter release help to stabilise the abnormal signals from the inner ear to the brain, reducing vertigo and dizziness.
