Pharmacology
Indication For the reduction of episodes of vertigo association with M?ni?re's disease.
Mechanism of action Not Available
Absorption When given orally, betahistine is rapidly absorbed from the gastrointestinal tract.
Protein binding Very low.
Biotransformation Betahistine is metabolized primarily into 2-pyridylacetic acid and is subsequently excreted in the urine.
Route of elimination Renal
Toxicity Symptoms of overdose (< 640 mg) include mild to moderate nausea, dry mouth, dyspepsia, abdominal pain and somnolence. More serious complications such as convulsions, pulmonary or cardiac complications, may occur with higher intentional overdoses (> 640 mg).
Affected organisms
  • Humans and other mammals
