Why this happens

Lansoprazole is a proton pump inhibitor used to reduce stomach acid, while mirabegron is a beta-3 adrenergic agonist used for overactive bladder. They are processed by different pathways in the liver and do not interfere with how the other is absorbed or excreted.

Severe uncontrolled high blood pressure

Do not take mirabegron if your blood pressure is very high (180/110 mmHg or higher) as it can cause a dangerous further increase in blood pressure. Your doctor should check your blood pressure before and during treatment.
