Practolol is a beta-blocker medication that is commonly used to treat high blood pressure, chest pain, and irregular heartbeat. Although there are no exact synonyms for practolol, there are other beta-blockers that have similar effects, including atenolol, metoprolol, propranolol, nadolol, and bisoprolol. These medications work to slow down the heartbeat and reduce the workload on the heart, which can help to lower blood pressure and improve heart function. It is important to note that these medications may have slightly different side effects and dosing recommendations, so it is best to talk to your doctor before starting any new medication.
