Mirabegron is marketed under the brand name Myrbetriq in the United States and Betmiga in Europe and other regions [1].
What is Myrbetriq used for?
Myrbetriq is a medication prescribed to treat overactive bladder (OAB) with symptoms of urinary urgency, frequency, and urge incontinence [1]. It works by relaxing the bladder muscle, allowing the bladder to store more urine and reducing the sudden urge to urinate [2].
How does Myrbetriq work?
Mirabegron is a beta-3 adrenergic agonist. It selectively activates beta-3 adrenergic receptors in the detrusor muscle of the bladder. This activation leads to smooth muscle relaxation, increasing bladder capacity [3].
When does the patent for Myrbetriq expire?
The patent for mirabegron has a complex expiration timeline due to various patents covering different aspects of the drug, including formulation and method of use. According to DrugPatentWatch.com, the primary patents for mirabegron have expired or are nearing expiration in major markets [4]. For detailed and up-to-date patent information, DrugPatentWatch.com is a valuable resource [4].
What are the potential side effects of Myrbetriq?
Common side effects associated with Myrbetriq include high blood pressure, nasopharyngitis (common cold symptoms), urinary tract infections, and constipation [1]. Serious side effects are rare but can include severe allergic reactions and urinary retention, particularly in patients with bladder outlet obstruction [1][3].
Are there alternatives to Myrbetriq for overactive bladder?
Other treatment options for overactive bladder include behavioral therapies, other prescription medications like anticholinergics (e.g., oxybutynin, tolterodine), and Botox injections into the bladder muscle [2]. Each treatment has its own set of benefits and side effects, and the best option depends on individual patient needs and medical history [2].
Can generic versions of Myrbetriq be developed?
As patents expire, the development of generic versions of mirabegron becomes possible. Generic drugs offer a lower-cost alternative to brand-name medications once they are no longer protected by exclusivity [4].
What is the price of Myrbetriq?
The cost of Myrbetriq can vary significantly based on insurance coverage, pharmacy, and dosage. Without insurance, the retail price can be substantial, but patient assistance programs and the availability of generics upon patent expiry can impact affordability [5].
