Overview

Mirabegron is commercially available as Myrbetriq. It is an extended-release tablet administered orally. It was approved by the United States (US) government in 2012. Mirabegron is a beta-3 adrenergic agonist. It is used for the treatment of overactive bladder. The advancement of drug combination is the use of Mirabegron with a muscarinic antagonist since April 2018. Also, the US government has given precautionary measures for treating patients with urinary retention due to bladder obstruction. Now, there is a major change in the dosage of Mirabegron with a muscarinic antagonist for treating the overactive bladder.

How Does Mirabegron Work?

Mirabegron is a white powder and is insoluble in water. The solubility increases in methanol and dimethyl sulfoxide. Recent research shows that cloning human cells shows a beta-3 adrenergic receptor for Mirabegron. The activation of beta-3 adrenergic receptors relaxes the detrusor smooth muscle. It gets activated during the storage phase of the urinary bladder. These receptors increase the bladder capacity. Though Mirabegron shows less intrinsic activity for cloned receptors like human beta-1 adrenergic receptor and beta-2 adrenergic receptor, stimulation of beta-1 receptors occurred at a 200 mg dosage.

What Are the Uses of Mirabegron?

  • Adult Overactive Bladder - Mirabegron monotherapy is indicated in patients with increased urinary frequency and urgency.

  • Mirabegron Combination Therapy With Solifenacin Succinate - Mirabegron is used in combination with Solifenacin succinate to treat adult patients with overactive bladder with the symptoms of urinary incontinence and urgency.

  • Pediatric Neurogenic Detrusor Overactivity - Mirabegron granules are used to treat children three years of age and above with pediatric neurogenic detrusor overactivity. Mirabegron tablets are indicated for the treatment of neurogenic detrusor overactivity for children weighing above 35 kgs.

For Patients

What Should You Know About Overactive Bladder?

Adult patients with overactive bladder pass urine out frequently. They show symptoms like wanting to urinate more than eight times a day and two to three times at night. These patients have a sudden urge to urinate. If not, there is a leakage of urine immediately.

What Are the Causes of An Overactive Bladder?

When the healthy bladder has urinary waste, the brain sends signals to the bladder. The bladder helps in passing the urinary waste through the urethra, following which the bladder relaxes. But in an overactive bladder, the brain passes signals to the empty bladder. The muscles present in the bladder are excessively active.

Nervous disorders, too much fluid intake, excess caffeine intake, pre-existing diseases like diabetes, and post-menopause in women may cause an overactive bladder. It is commonly present in patients above 35 years of age.

What Happens In An Overactive Bladder?

The overactive bladder affects occupation, social life, and sleep. The patient passes urine in drips before reaching the bathroom. It affects the relationship and sex life with the partner. Constant leakage of urine gives rise to infection and skin problems in the private parts.

What is Neurogenic Detrusor Overactivity (NDO) in Pediatric Patients?

The frequent contraction of the detrusor muscle in children leads to uncontrolled urinary discharge. It is due to the neurological abnormality, which in turn inhibits the signals of the central nervous system and urinary bladder. This causes involuntary urination. The symptoms and retention of the urinary bladder can be improved using Mirabegron.

Dosage

The oral dosage of Mirabegron extended-release tablets contains 25 mg or 50 mg. It has inactive ingredients like polyethylene oxide, glycol, hydroxypropyl cellulose, magnesium, and ferric oxide.

  • Mirabegron Monotherapy - The recommended oral dosage of Mirabegron is 25 mg once daily. The oral dosage can be increased up to 50 mg after the administration for four to eight weeks.

  • Mirabegron Combination Therapy with Solifenacin Succinate - The combination therapy of Mirabegron and Solifenacin succinate should be administered orally at a starting dosage of 25 mg and 5 mg, respectively. The oral dosage can be increased up to 50 mg of Mirabegron once daily after four to eight weeks.

Recommended Dose for Pediatric Patients Above 3 Years of Age:

The appropriate product is selected depending on the weight of the pediatric patient.

For the pediatric patient weighing 11 kgs to 22 kgs, 24 mg is the starting dose and can be increased to 48 mg. For pediatric patients weighing 22 kgs to 35 kgs, the starting dose should be 32 mg and can be increased to 64 mg.

Recommended Dosage for Pediatric Patients Weighing More Than 35 kgs:

Mirabegron granules (extended-release) are administered once daily as an oral suspension. The starting oral dose should be 48 mg once daily. It can be increased to 80 mg once daily after four to eight weeks.

Dosage for Pediatric Patients

Contraindications

It is contraindicated for patients who are sensitive to drugs and experience symptoms like nausea, headache, hypertension, diarrhea, and tachycardia.

For Doctors

Indication

Mirabegron is the first line of treatment for overactive bladder.

Pharmacodynamics

Urinary Bladder - Research was conducted to assess the maximum urinary flow rate and pressure in the detrusor muscle during maximum flow rate. After administering Mirabegron to the patient once daily for three months, it was observed that the mean flow rate did not correlate with the detrusor pressure. But it should be administered with caution.

Heart - A study was conducted on four types of subjects by administering multiple doses of Mirabegron (50 mg, 100 mg, and 200 mg) once daily. The QT interval was determined in the electrocardiography. High dosage results in a mean difference of 3.5 seconds from placebo in the QT interval after five hours of drug administration. The patients administered 200 mg showed a substantial increase in the blood level of 50 mg. The QT interval in such cases is 6.1 msec after four to five hours of administering the drugs. In females, the interval goes up to 13.4 sec. Thus the heart rate depends on the dosage. The heart rates are 6.7, 11, and 17 beats per minute for 50 mg, 100 mg, and 200 mg doses respectively. The change in pulse rate from baseline was found to be 1 bpm.

Effects on Blood Pressure - After administering the dosage of 50 mg, there is a mean increase of 4.0/1.6 mm Hg in the systolic and diastolic blood pressure. Continuous administration for ten days shows an increase in systolic blood pressure. The mean increase of systolic blood pressure for 50 mg, 100 mg, 200 mg, and 300 mg are 2.5 mm Hg, 4.5 mm Hg, 5.5 mm Hg, and 6.5 mm Hg respectively. The alteration in systolic and diastolic blood pressure can be reversed after the withdrawal of Mirabegron. When Mirabegron was administered with 5 mg Solifenacin succinate, no difference was found in systolic and diastolic blood pressure. It is detected after 24 hours using ambulatory blood pressure monitoring (ABPM).

Effects on Intraocular Pressure - Administering Mirabegron one dose daily did not increase the intraocular pressure. It was given after treating the patients for two months. When 100 mg Mirabegron was administered, there was a mean difference of 0.3 mm Hg from the baseline.

Pharmacokinetics

Absorption

The study was conducted on healthy volunteers. Mirabegron was found to reach the plasma after 3.5 hrs. The dosage of Mirabegron 25 mg and 50 mg show a bioavailability of 29 % and 35 % respectively. In females, there was a two-fold increase of 2.9 and 2.6-fold when the dosage was increased from 50 mg to 100 mg. There was an increase in Cmax and AUCtau. When the Mirabegron dosage was increased from 50 mg to 200 mg, there was a four-fold increase by 8.4 and 6.5 fold. It also had an increase in Cmax and AUCtau. On administering a single daily dose, the concentrations were maintained at a steady state.

Mirabegron for Overactive Neurogenic Detrusor in Children:

In pediatric patients, a single dose of Mirabegron extended-release was administered in the fasting state for up to four to five hours. After that, an analysis was made to predict the median Tmax. It continued for three to four hours. This analysis gave an effective result of Mirabegron for the management of overactive neurogenic detrusor muscles in kids. There was a 120 % AUC increase in the kids who are in the fed state. There was an increase of 170 % and 80 % in Cmax and AUC for the kids in a starved state.

What Is the Effect of Food on Mirabegron?

In adults, Mirabegron monotherapy did not produce any significant changes in adults with or without food.

Distribution

The monotherapy of Mirabegron in adults distributes the drug widely inside the body. After an intravenous administration, there is a steady-state volume of 1670 L. 71 % of Mirabegron is bound to human plasma proteins and has a greater affinity to albumin. It has a moderate affinity to alpha-1 glycoprotein. In addition, it adheres to RBC (red blood cells). There was a 2-fold increase of Mirabegron in the erythrocyte steady-state to plasma.

Distribution in Pediatric Patients With Overactive Detrusor Muscle:

In children, the Mirabegron distribution is relatively large compared to adults. The ratio of V2/F in children in the fed state shows a distribution range of 4895 L to 13726 L. The drug distribution increases with weight.

Elimination of Mirabegron in Adults:

The half-life of Mirabegron is 50 hours. It is the terminal elimination of the drug in adults with overactive detrusor muscle.

Elimination of Mirabegron in Pediatric Patients:

The half-life of Mirabegron in children is approximately 26 to 31 hours.

Metabolism

The multiple metabolic processes like dealkylation, hydrolysis, oxidation, and glucuronidation are involved in the metabolism of Mirabegron. The major circulating component is Mirabegron. The metabolites present in plasma and phase 2 glucuronides represent 16 % and 11 % respectively. They are inactive to the beta-3 adrenergic receptor. The isoenzymes CYP2D6 and CYP3A4 play an important role in eliminating the drug. The healthy volunteers with poor metabolism of CYP2D6 due to the genotype had Cmax and AUCtau of 16 % and 17 % which were higher than the patients with extensive metabolizers. The butylcholinesterase, glucuronosyltransferase, and alcohol dehydrogenase are also involved in the metabolism of Mirabegron.

Excretion

Mirabegron is excreted completely at 57 L/h from the body after an intravenous administration. The half-life elimination of Mirabegron is 50 hours. The renal clearance of Mirabegron is 13 L/h. It involves 25 % of the total clearance. It occurs in glomerular filtration. The unchanged Mirabegron has been eliminated as 6 % and 12.2 % for the dosage of 25 mg and 100 mg, respectively. Administering 160 mg to adults gives a radioactive dose of 55 % in urine and 34 % in faeces. 25 % of unchanged Mirabegron was present in urine, but there was nothing in the feces.

Specific Population

  • Age- In patients above 65 years, the Cmax and AUC of Mirabegron after multiple doses are similar to the individuals aged 18 to 45 years.

  • Gender - The pharmacokinetics of Mirabegron had no specific impact on the gender of patients aged 3 to 18 years.

  • Race - The exposure of Mirabegron to Japanese was proved to be higher than in North Americans. However, there was a minimal difference if the Cmax and AUC were modified depending on the weight.

  • Mirabegron Study in Renal Impairment Patients - In adults with mild renal impairment, after the administration of 100 mg Mirabegron, the glomerular filtration rate was estimated as 60 to 89 mL/min, and there was an increase by 6 % and 31 % of Cmax and AUC respectively. In patients with moderate renal impairment with a glomerular filtration rate of 30 to 58 mL/min, the Cmax and AUC have an increase up to 23 % and 66 %, respectively. In severe renal impairment conditions, with a glomerular filtration rate of 15 mL/min, the value of Cmax and AUC were found to be 92 % and 118 % higher than healthy individuals who had a normal renal function. Patients with a glomerular filtration rate of less than 15 mL/min are considered end stage renal disease and require dialysis for management. The Mirabegron study was not made in such cases.

  • Mirabegron Study in Hepatic Impairment Patients - After 100 mg Mirabegron administration in adult patients with mild hepatic illness, the Cmax and AUC increased by 9 % and 19 % compared to adult patients. The individuals with moderate hepatic illness had Cmax and AUC values of 175 % and 65 % respectively. It is not studied in adults with severe hepatic disease.

Clinical Trials

The adverse drug reactions vary from clinical practice. In a double-blind study in more than 2000 patients, the safety and efficacy of Mirabegron was evaluated. Atrial fibrillation and prostate cancer were the two potential adverse effects reported in a few patients.

  • Cardiac Disorders - The adult patients had palpitations associated with increased blood pressure.

  • Eye Disorders - Glaucoma is observed in elderly patients.

  • Gastrointestinal Disorders - There is abdominal distension with inflammatory bowel and dyspepsia.

  • Infections - Sinusitis and rhinitis.

  • Renal and Urinary Disorders - Pain in the bladder due to nephrolithiasis.

  • Reproductive System - Inflammation in the urethra and vaginal infection called vulvovaginal pruritus.

  • Skin and Subcutaneous Tissue Disorders - Itching in the urethra, lip edema, vasculitis, and purpura.

  • On investigation using serum ALT (alanine transaminase) and AST (aspartate transaminase) the markers of osteoarthritis increased 10-fold from baseline.

  • Neoplasms like breast cancer, lung cancer, and prostate cancer were reported in patients who were administered 100 mg Mirabegron.

  • One patient administered with 100 mg Mirabegron reported Stevens-Johnson syndrome with elevated alanine transaminase (ALT), aspartate transaminase (AST), and bilirubin.

  • The commonly seen adverse effects of combination therapy with Mirabegron and Solifenacin succinate are blurred vision, squamous cell carcinoma, and basal cell carcinoma.

  • In pediatric patients with neurogenic detrusor overactivity the clinical trial study duration was 52 weeks. The common adverse reactions like nasopharyngitis and urinary tract infection due to the intake of Mirabegron granules.

Drug Interaction Studies

What Are The Effects of Other Drugs on Mirabegron?

There are various metabolic activities involved in the metabolism of Mirabegron. It is the substrate of enzymes like CYP3A4 and CYP2D6, receptors like butyrylcholinesterase, and transporters like glycoprotein. It also involves the organic transporters OCT1, OCT2, and OCT3. The Glibenclamide, Gliclazide, and Tolbutamide agents did not affect the Mirabegron metabolism.

What Are The Effects of Mirabegron on Other Drugs?

Recent research has proved that Mirabegron is a moderate and time-dependent inhibitor of the enzyme-like CYP2D6 and a weak inhibitor of the CYP3A enzyme. Mirabegron does not affect the drug metabolized by the P450 enzymes. It inhibits only at a very low concentration. There is no action on CYP1A2 and CYP3A enzymes. It reduced the action of P-gp-mediated drug transport. The study stated that the Mirabegron is no longer effective in the OCT medicated drugs. It also did not affect the glibenclamide and tolbutamide metabolism.

What is The Effect of Alcohol on Mirabegron?

Alcohol increases the dissolution of Mirabegron at pH 6.8. But there was no dissolution at a pH of 1.

Interaction of Mirabegron Extended-Release Tablets with Other Drugs

The study was conducted on a 23-year-old male and a few female subjects to analyze the effect of Mirabegron in patients when co-administered Metoprolol, Metformin, and Ketoconazole. Ketoconazole has increased drug exposure (the Cmax and AUC were 45 % and 80 % after the administration of 400 mg). It was given a week before the administration of 100 mg Mirabegron.

The Cmax and AUC of Metoprolol increased by 90 % and 230 % after administering 160 mg of Mirabegron continuously for a week.

The Cmax and AUC of Desipramine increased by 79 % and 241 % after administering 100 mg of Mirabegron continuously for two weeks.

The Cmax and AUC of Digoxin increased by 14 % and 10 % respectively.

The Cmax and AUC of Tamsulosin increased by 47 % and 55 % respectively. It is correlated to the inhibition of cytochrome P450.

Carcinogenesis

The study conducted about the carcinogens showed no carcinogenic effect at a 50 mg Mirabegron dosage with an AUC of 38 to 45 fold.

Mutagenesis

There were no significant chromosomal abnormalities in the peripheral blood lymphocytes of the healthy individuals.

Fertility

The Mirabegron 100 mg dosage did not affect fertility in men and women.

Patient Counseling Information

Ensure that the patient reads the US Food and Drug Administration (FDA) guidelines before taking the medications.

Blood Pressure

Give prior information that the Mirabegron granules increase the blood pressure. So they should monitor their blood pressure periodically and consult a medical professional if necessary.

Urinary Retention

Inform the patients about urinary retention due to bladder obstruction and muscarinic antagonist medications. Ask the patient to consult an urologist if they experience any of the symptoms.

Angioedema

The Mirabegron granules cause angioedema. In severe cases it leads to swelling of the upper respiratory tract and causes life threatening conditions. The patient should discontinue the drug and seek medical help immediately.

Drug Interaction

The patients should inform their physician about the use of prescribed and over the counter medications and supplements, because this can interfere with Mirabegron granules. Sometimes the patient requires a dose adjustment and frequent monitoring of the vital signs.

Mirabegron Administration

Ask the adult patient to swallow the Mirabegron with water and avoid chewing. Most importantly, the tablets should not be crushed or divided while swallowing. Advise the adult patients to take Mirabegron before or after eating food.

In the case of pediatric patients, ask the caretaker to provide Mirabegron tablets for children to swallow using water. It should not be chewed, crushed or divided and should be taken only after eating the food.

Advise the caretakers of pediatric patients to measure the Mirabegron granules and read the instructions before giving the oral suspension with extended release. It should be consumed within an hour after preparation. Also, it should not be stored for the next day. It should be taken once daily after food.

Ask the caretaker to shake the bottle for a minute before use if it is not used for more than 2 days. It should be shaken vigorously for a minute so that there is a foam accumulation on the top of the suspension. It will go off after one to two minutes.

Missed Dose

In case of missed dose, advise the caretakers or patients to take the medication as soon as they remember or most probably within 12 hours of the missed dose. If it is more than 12 hours, then the drug can be skipped and advised to take the next dose as usual.

For Patients

Adults

Mirabegron is prescribed by the physician and can be used alone or co-administered with Solifenacin succinate to the adults. It is usually preferred for patients with symptoms due to overactive bladder. The symptoms include:

Frequently Asked Questions

1.

When Can the Mirabegron Drug Be Used?

Mirabegron is used mainly for the treatment of overactive bladder. Symptoms of incontinence (loss of bladder control), a strong feeling to urinate right away, and frequent urination are treated with this drug. It is also used in the case of neurogenic detrusor overactivity (bladder dysfunction among those affected with multiple sclerosis and spinal cord injury).

2.

Which Is the Safest Medication for an Overactive Bladder?

Medications that help relieve the symptoms of overactive bladder include mainly anticholinergics and beta-3 adrenergic agonists. Commonly used anticholinergics are Oxybutynin, Tolterodine, Fesoterodine, etc.

3.

Which Is the Best Time to Take Mirabegron?

Mirabegron can be taken at any time, but every day it should be taken at the same time. It should be taken before or after the food. It can be taken with the help of water. It should not be crushed or chewed while taking.

4.

Does Mirabegron Medication Cause High Risk?

No, Mirabegron is not a high-risk medication. It is highly safe and has high efficacy, which is used in conditions like incontinence, increased urinary frequency, etc.

5.

Does Mirabegron Affect the Liver?

No, Mirabegron does not affect the liver. It is a beta-3 adrenergic agonist used in the case of an overactive bladder. It does not cause any rise in liver enzymes or any injury to the liver.

6.

How Effective Is the Action of Mirabegron?

Mirabegron starts its action after three to four hours after it has been taken. It acts by relaxing the muscles surrounding the bladder. Treatment with Mirabegron takes longer as it may take four to eight weeks to observe the improvements in the condition called overactive bladder.

7.

Mention the Alternative Drug of Mirabegron if Present.

Yes, Oxybutynin, Gemtesa, Tolterodine, Vesicare, and Botox are the drugs that can be used as an alternative to Mirabegron in treating overactive bladder. 

8.

What Are the Risks Caused by Mirabegron?

Risks associated with Mirabegron are increased risk of high blood pressure, symptoms of the common cold like sneezing, running nose, and congestion of the nose, urinary tract infections, headache, retention of urine in the bladder, breathing difficulty due to swelling of face, lips, tongue, and throat.

9.

Is the Urinary Retention Caused by Mirabegron?

Yes, Mirabegron may cause urinary retention among those who suffer from an enlarged prostate gland. These generally suffer from bladder outlet obstruction. But this is not a side effect of Mirabegron.

10.

How to Stop Frequent Urination at Night?

Frequent urination can be stopped by limiting fluid intake at night by around three to four hours before going to sleep, limiting caffeine and alcohol intake, managing the diuretics, keeping the legs elevated or making use of compression socks, incorporating kegel exercise in day-to-day life, and making use of the protective pad to avoid leakages.

11.

How Is Mirabegron Different From Solifenacin?

Miragren is better than Solifenacin. That is because, though both have the same therapeutic uses in the treatment of overactive bladder, Solifenacin causes severe constipation when compared to Mirabegron.

12.

Which Is the Best Sleeping Position for an Overactive Bladder?

The best sleeping position in case of an overactive bladder is to sleep sideways. Elevating the legs may also help in this condition throughout the night. 

13.

Does Sitting for Long Worsen an Overactive Bladder?

Yes, sitting for long periods, like five hours or more, may cause an overactive bladder, and its symptoms may get worse. Studies have shown that sedentary lifestyles may worsen incontinence, and older women who do regular exercise are found to have better functioning pelvic floor muscles.

14.

Does the Action of Holding Pee Help an Overactive Bladder?

No, holding pee does not help an overactive bladder. This may be because of the overstretching of the bladder that occurs due to the holding of pee. This worsens the condition by causing a lack of coordination between the bladder muscle and the urethra.
