Differentiation is an operation that allows us to find a function that outputs the rate of change of one variable with respect to another variable. Informally, we may suppose that we're tracking the position of a car on a two-lane road with no passing lanes.
Overactive bladder is typically treated with a class of drugs called anticholinergics. Examples include DetrolÂ®, DitropanÂ®, VesicareÂ®, and EnablexÂ®. Mirabegron is a new drug approved for overactive bladder that has a different mechanism of action than the anticholinergics. MECHANISM: Mirabegron (MyrbetriqÂ®) stimulates Beta-3 adrenergic receptors. Stimulation of Beta-3 adrenergic receptors in the bladder muscle causes it to relax.
Myrbetriq will be supplied in 25 mg and 50 mg tablets and is expected to be available in pharmacies in the fourth quarter of 2012. Mirabegron was approved in Japan in July 2011, and regulatory applications are under review in several other countries. Myrbetriq â¢ (mirabegron) is a beta- 3 adrenergic agonist indicated for the treatment of overactive bladder (OAB) with symptoms of urge urinary incontinence, urgency, and urinary frequency.
