Medication Safety Issues
Sound-alike/look-alike issues:

Vibegron may be confused with vigabatrin, Vigadrone.

Metabolism/Transport Effects

Substrate of CYP3A4 (minor), P-glycoprotein/ABCB1 (minor); Note: Assignment of Major/Minor substrate status based on clinically relevant drug interaction potential

Drug Interactions

Note: Interacting drugs may not be individually listed below if they are part of a group interaction (eg, individual drugs within “CYP3A4 Inducers [Strong]” are NOT listed). For a complete list of drug interactions by individual drug name and detailed management recommendations, use the Lexicomp drug interactions program by clicking on the “Launch drug interactions program” link above.

Digoxin: Vibegron may increase the serum concentration of Digoxin. Risk C: Monitor therapy

Pregnancy Considerations

Adverse events were not observed in animal reproduction studies except at the highest doses, which also caused maternal toxicity.

Breastfeeding Considerations

It is not known if vibegron is present in breast milk.

According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and the benefits of treatment to the mother.

Monitoring Parameters

Postvoid residual urine volume at baseline and as clinically indicated thereafter (AUA [Lerner 2021]); signs and symptoms of urinary retention.

Mechanism of Action

Vibegron, a selective human beta-3 adrenergic receptor agonist, activates beta-3 adrenergic receptors in the bladder resulting in relaxation of the detrusor smooth muscle during the urine storage phase, thus increasing bladder capacity.

Pharmacokinetics (Adult Data Unless Noted)

Distribution: Vd: 6,304 L.

Protein binding: ~50%.

Metabolism: Minor metabolism hepatically via CYP3A4.

Half-life elimination: 30.8 hours.

Time to peak: ~1 to 3 hours.

Excretion: Feces: ~59% (54% as unchanged); Urine: 20% (19% as unchanged).
