Question 3

How does Mirabegron work?

Accepted Answer

How Mirabegron Works

Mirabegron belongs to a class of medications called beta-3 adrenergic agonists. It works by targeting specific receptors found in the detrusor muscle, which is the muscle that makes up the wall of the bladder.

In a healthy bladder, the detrusor muscle relaxes to allow the bladder to fill with urine and contracts when it is time to urinate. For those with an overactive bladder, this muscle may contract involuntarily, causing a sudden and frequent need to go. Mirabegron helps manage these symptoms through the following actions:

Relaxing the bladder: The medication activates beta-3 receptors, which signals the bladder muscle to stay relaxed while it is storing urine.

Improving capacity: When the muscle is relaxed, the bladder can expand more effectively, allowing it to hold a larger volume of urine.

Controlling urgency: By preventing the bladder muscle from contracting too early or unexpectedly, the medication reduces the frequency of bathroom visits and the sudden, intense urge to urinate.

How to Take Mirabegron

Mirabegron is usually taken once a day. It is important to take this medication exactly as directed by your healthcare provider to achieve the best results.

Administration Instructions

Extended-release tablets: These should be swallowed whole with a glass of water. Do not crush, chew, or break the tablets, as this can cause the medication to be released into the body too quickly.

Oral suspension (liquid): If you are using the liquid form, shake the bottle well before measuring a dose. Always use a proper medical measuring device, such as an oral syringe or dose cup, rather than a household spoon to ensure the correct amount is taken.

Taking with Food

The extended-release tablets can generally be taken with or without food. However, instructions for the liquid suspension may vary; it is often recommended to be taken with food. Check the specific instructions provided with your prescription.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose and continue with your regular routine. Do not take two doses at the same time to make up for a missed one.

Pregnancy

There is limited information regarding the safety of using mirabegron during pregnancy. It is currently unknown whether this medication can cause harm to an unborn baby.

If you are pregnant or planning to become pregnant, discuss the risks and benefits of this treatment with your doctor. If you become pregnant while taking this medication, notify your healthcare provider immediately.

Breastfeeding

It is not known if mirabegron passes into human breast milk or how it might affect a nursing infant.

FDA Approval and Indications

The FDA has also approved mirabegron for the treatment of neurogenic detrusor overactivity (NDO) in pediatric patients 3 years of age and older.

Regulatory Warnings and Precautions

While mirabegron does not carry a boxed warning, the FDA-approved labeling includes specific precautions regarding blood pressure. The medication can increase blood pressure, and it is recommended that healthcare providers measure blood pressure before starting treatment and monitor it periodically. It is not recommended for patients with severe, uncontrolled hypertension.

The FDA labeling also contains information regarding pharmacogenomics. Mirabegron is a moderate inhibitor of CYP2D6, an enzyme involved in drug metabolism. This regulatory information is provided to help clinicians manage potential drug interactions with other medications metabolized by this same pathway.
