How it works

From the US prescribing label for the same active substance (Buspirone Hydrochloride). It describes the substance, not this exact product.

The mechanism of action of buspirone is unknown.

Buspirone differs from typical benzodiazepine anxiolytics in that it does not exert anticonvulsant or muscle relaxant effects.

The shape is a standard model drawn from the two times above, not a measurement. How fast a medicine acts and wears off also depends on the dose, the form and the person.
How the body breaks it down

Buspirone is metabolized primarily by oxidation, which in vitro has been shown to be mediated by cytochrome P450 3A4 (CYP3A4) (see PRECAUTIONS, Drug Interactions ).

How it leaves the body

In a single-dose study using 14 C-labeled buspirone, 29% to 63% of the dose was excreted in the urine within 24 hours, primarily as metabolites; fecal excretion accounted for 18% to 38% of the dose.

With food

The effects of food upon the bioavailability of buspirone hydrochloride tablets have been studied in eight subjects.

Safety of the active substance

From the US prescribing label for the same active substance (Buspirone Hydrochloride). It describes the substance, not this exact product.

Must not be used by
  • Buspirone hydrochloride tablets are contraindicated in patients hypersensitive to buspirone hydrochloride.
  • The use of monoamine oxidase inhibitors (MAOIs) intended to treat depression with buspirone or within 14 days of stopping treatment with buspirone is contraindicated because of an increased risk of serotonin syndrome and/or elevated blood pressure.
  • The use of buspirone within 14 days of stopping an MAOI intended to treat depression is also contraindicated.
  • Starting buspirone in a patient who is being treated with reversible MAOIs such as linezolid or intravenous methylene blue is also contraindicated because of an increased risk of serotonin syndrome (see WARNINGS, DOSAGE AND ADMINISTRATION and DRUG INTERACTIONS ).
