Buspirone is an anti-anxiety drug . Its main advantage over benzodiazepines is that, according to the current state of research, it is not addictive. It is also not sedating . In contrast to benzodiazepines, the effect does not occur immediately after ingestion, but only after a few weeks (two or more) of regular use. Buspirone has no affinity for GABA receptors . Presumably it acts as a partial agonist at 5-HT 1A receptors and as an antagonist at D 2 receptors . The active ingredient was patented by Bristol Myers in 1971 and by Mead Johnson in 1973 . There are also generic drugs on the market. It is used as a hydrochloride . Buspirone was first approved in 1986 for the indication of generalized anxiety disorder .
Side effects
The most common side effects (<1:10) are dizziness, tiredness, nausea and headache. Frequently (<1: 100) tachycardia , nervousness , insomnia , paresthesia , diarrhea , accommodation disorders , depressive discomfort, nightmares , confusion and blurred vision occur.
Interactions
Buspirone is metabolized via the cytochrome P450 3A4 . This has the consequence that the plasma level of buspirone is lowered by inducers of this enzyme (e.g. carbamazepine ) or increased by inhibitors (e.g. grapefruit juice , cimetidine ).
Serotonin syndrome can occasionally occur in connection with drugs with a strong serotonergic effect ( SSRI , clomipramine , St. John's wort ) .
