What is Generic?

What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Myrbetriq is a medication that helps relax the muscles of the bladder, which reduces spasms. It is prescribed for adults to alleviate symptoms of overactive bladder. In some cases, it may be used alongside solifenacin. Additionally, Myrbetriq is used in children to treat neurogenic detrusor overactivity (NDO), a condition characterized by urinary incontinence resulting from permanent nerve damage caused by conditions like multiple sclerosis or spinal injury.

When considering treatment options for an Overactive Bladder, it's important to consider factors such as effectiveness, potential side effects, and the Myrbetriq cost.

What is Overactive Bladder (OAB)?

Overactive bladder is a condition characterized by a sudden and frequent urge to urinate. People with this condition may experience urinary urgency, where they feel the need to urinate immediately, often resulting in involuntary urine leakage. Overactive bladder can significantly impact a person's quality of life and may be caused by a range of factors, including bladder muscle overactivity and nerve problems. Treatment options range from lifestyle changes and behavioral therapies to medications and, in some cases, medical procedures.
