From the FDA Drug Label
Buspirone is metabolized by the liver and excreted by the kidneys. A pharmacokinetic study in patients with impaired hepatic or renal function demonstrated increased plasma levels and a lengthened half-life of buspirone Therefore, the administration of buspirone hydrochloride tablets to patients with severe hepatic or renal impairment cannot be recommended
The FDA drug label does not specifically address the safety of buspirone in patients with hepatic steatosis (fatty liver disease). However, it does mention that buspirone is metabolized by the liver and that patients with severe hepatic impairment should not be given the drug due to increased plasma levels and a lengthened half-life of buspirone 1.
- Hepatic steatosis is a condition where there is an accumulation of fat in the liver, which can impair liver function.
- Since the label warns against use in patients with severe hepatic impairment, it is likely that buspirone should be used with caution in patients with hepatic steatosis.
- The label does not provide specific guidance on the use of buspirone in patients with hepatic steatosis, and the decision to use the drug in these patients should be made on a case-by-case basis, taking into account the potential risks and benefits.
From the Research
Buspirone should be used with caution in patients with hepatic steatosis (fatty liver disease), as it is primarily metabolized by the liver and liver impairment can lead to higher blood levels and increased risk of side effects. The medication's pharmacokinetics are significantly altered in patients with liver disease, with studies showing that the area under the plasma concentration-time curve (AUC) and maximum concentration (Cmax) of buspirone are substantially higher in patients with hepatic impairment compared to healthy individuals 2, 3. For patients with mild to moderate fatty liver disease without significant liver dysfunction, buspirone may still be used, but often at reduced doses. Typically, doctors might start at a lower dose (such as 5 mg twice daily instead of the usual 7.5-15 mg twice daily) and increase gradually while monitoring for side effects.
- Key considerations for using buspirone in patients with hepatic steatosis include:
- Starting with a lower dose and gradually increasing as needed and tolerated
- Close monitoring of liver function and adjustment of the dose as necessary
- Avoiding buspirone or using it with caution in patients with severe liver disease or cirrhosis
- Regular assessment of the patient's specific liver condition and adjustment of the dosing strategy accordingly Patients with severe liver disease or cirrhosis should generally avoid buspirone or use it only under close medical supervision with substantial dose reductions, as impaired liver function can slow the clearance of buspirone from the body, potentially leading to drug accumulation and toxicity 3. Regular liver function monitoring is advisable while taking buspirone if you have fatty liver disease. Always consult with your healthcare provider before starting or adjusting any medication regimen, as they can evaluate your specific liver condition and determine the appropriate dosing strategy.
