‘People with overactive bladder have urgency with or without frequency and nocturia. Antimuscarinics such as oxybutynin, tolterodine, solifenacin and darifenacin are the mainstay of drug treatment . They are often used in conjunction with bladder training.
Mirabegron is available as 25 mg and 50 mg film-coated tablets. It is an agonist of beta3 adrenergic receptors. It works by activating these receptors in
the detrusor muscle of the bladder. This relaxes the muscle and increases bladder capacity’.
