What is Gemtesa?

Gemtesa is used to treat overactive bladder (OAB) symptoms, including urinary urgency, urinary frequency, and urge incontinence. Gemtesa  helps to relieve urinary symptoms in adults with overactive bladder or men with OAB who are taking medicine for benign prostatic hyperplasia (BPH).

Gemtesa works by relaxing the bladder muscle so the bladder can hold more urine which may reduce the urgency to use the bathroom and decrease the frequency of urinary leaks or wetting accidents.  

Gemtesa generic name is vibegron.

Gemtesa is a once-daily tablet that is swallowed whole with water or maybe crushed, mixed with a tablespoon (~15 mL) of applesauce, and taken immediately with a glass of water. The tablet can be taken with or without food.

Who can use Gemtesa?

Gemtesa is used to treat:

• Overactive bladder symptoms in adults, including symptoms of urinary urgency, frequency, and urinary urge incontinence.
• Overactive bladder symptoms in men taking medicines for benign prostatic hyperplasia (BPH). 

How does Gemtesa work?

Gemtesa's mechanism of action (MOA)is by binding and activating β3-adrenergic receptor, which relaxes the muscles in the wall of the bladder (detrusor muscle), which increases bladder volume.

Gemtesa is from a class of medications called beta-3 agonists, or more specifically it is a selective human beta-3 adrenergic receptor agonist (β3-AR agonist).

• 1.8 fewer bathroom visits per day (compared to 1.3 fewer episodes for placebo)
• 2.7 fewer “need to urinate immediately” episodes (compared to 2 fewer episodes for placebo
