- Infection at the proposed injection site(s)
- Urinary tract infection at time of intradetrusor injection
- Urinary retention or post-void residual urine volume >200 mL in patients not routinely performing clean intermittent self-catheterization (for intradetrusor injection)
- Known hypersensitivity to vibegron or any components of GEMTESA
Adverse Reactions
Most common (>=2%) Urinary tract infection, dysuria, urinary retention, neck pain, headache, muscular weakness, eyelid ptosis, injection site pain, dysphagia, upper respiratory infection
Serious Spread of toxin effects, dysphagia and breathing difficulties, hypersensitivity reactions, autonomic dysreflexia, corneal exposure and ulceration, retrobulbar hemorrhage
Postmarketing Abdominal pain, alopecia, brachial plexopathy, peripheral neuropathy, arrhythmia, myocardial infarction, death associated with dysphagia and pneumonia, new onset or recurrent seizures
Most common (>=2%) Headache, nasopharyngitis, diarrhea, nausea, upper respiratory tract infection, urinary tract infection, bronchitis
Serious Urinary retention
Postmarketing Urinary retention, angioedema of the face and larynx, hypersensitivity reactions (urticaria, pruritus, rash, drug eruption), eczema, constipation
Pharmacology
Botulinum toxin type A that blocks neuromuscular transmission by inhibiting acetylcholine release at motor and autonomic nerve terminals through cleavage of SNAP-25, producing localized, reversible chemical denervation of muscle, sweat glands, or the detrusor depending on injection site.
Vibegron is a selective human beta-3 adrenergic receptor agonist; activation of the beta-3 adrenergic receptor increases bladder capacity by relaxing the detrusor smooth muscle during bladder filling.
