Propranolol
About Propranolol
Propranolol belongs to a group of medicines called beta-blockers used alone or together with other medicines to treat high blood pressure (hypertension), heart-related chest pain (angina), heart rhythm disorder (arrhythmia) and preventing symptoms of migraine headache and tremors (fits). It affects our heart and blood circulatory system, especially controlling blood through arteries and veins. High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure may reduce the risk of stroke and heart attacks.
Propranolol plays a vital role in relaxing our blood vessels by blocking the action of certain natural substances in your body. This lowers your blood pressure and helps reduce your risk of a stroke, a heart attack, other heart problems or kidney problems in the future. This medicine needs to be taken regularly to be effective.
You can take Propranolol orally with or without food or as directed by your physician. Swallow the whole tablet with a glass of water. Do not crush, chew or break it. Propranolol is preferable to take at the same time every day for better results. Propranolol is generally safe to consume. You may have common side effects like feeling dizzy or exhausted, cold hands or feet, difficulty sleeping, and nightmares. These side effects are usually mild and short-lived. However, if the side effects are persistent, reach out to your doctor.
Don't stop taking Propranolol without talking to your doctor first. Stopping Propranolol gradually may cause heart rhythm and blood pressure changes and cause chest pain or a heart attack. Your doctor will lower your dose gradually over some time to help prevent these symptoms. You should not use Propranolol if you have a very slow heartbeat, asthma, serious heart condition (sick sinus syndrome) or any heart blockage. Children weighing less than 4.5 pounds should not be given a Propranolol. It should not be given to children less than 12 years of age. Before taking Propranolol, you should tell the doctor if you have any muscle disorder (myasthenia gravis, rhabdomyolysis), breathing problems (COPD, bronchitis, emphysema), low blood sugar level (hypoglycaemia), low blood pressure (hypotension), depression, previous heart failure, liver/kidney disease, thyroid hormone disorder, adrenal gland cancer or problems with circulation (Raynaud's syndrome).
Uses of Propranolol
Medicinal Benefits
Propranolol works by blocking both beta receptors, namely beta 1 and beta 2. Propranolol blocks beta 1 receptor located in the heart's cells, lowering heart rate and decreasing heart blood pumping frequency, decreasing raised blood pressure. On the other hand, Propranolol also blocks beta 2 receptors located in the lungs (bronchioles) and blood vessels of skeletal muscle, narrowing it. This, in turn, lowers your overall body's blood pressure and helps reduce the risk of a stroke, a heart attack, heart problems or kidney problems in the future. Propranolol also improves the symptoms of heart-related chest pain (angina) and may increase a person's stamina to do exercise with angina. Propranolol is used in combination with thiazide diuretics and other medicines to treat high blood pressure. Additionally, Propranolol reduces symptoms of essential tremor (fits) and prevents migraine. Propranolol can reduce symptoms of too much thyroid hormone (thyrotoxicosis) and can be taken together with thyroid-related medicines to treat an overactive thyroid.

You should avoid discontinuing the use of Propranolol before undergoing any surgery. Intake of Propranolol may mask symptoms of diabetes. So tell your doctor if you have type 1 or type 2 diabetes. It may also worsen your symptoms of congestive heart failure and bradycardia (slow heart rate less than 60). You should regularly monitor your prothrombin time if Propranolol is taken with anti-coagulants like warfarin.
Drug Interactions
Drug-Drug Interactions: Propranolol may interact with other beta-blockers (acebutolol, atenolol, bisoprolol, carteolol, esmolol, metoprolol, nadolol, nebivolol or sotalol) causing a dangerous drop in the heart rate. Besides this, Propranolol should not be used with other blood pressure related medicines (lisinopril, enalapril, diltiazem, prazosin, terazosin, doxazosin), asthma medications (theophylline) or any other pain killers. If you are using these medicines tell your doctor before taking Propranolol.
Drug-Food Interactions: Propranolol severely interact with grapefruit and protein enriched foods. Using Propranolol together with ayurvedic, homeopathy, unani, herbal supplements or any other OTC items may decrease the effects of Propranolol. Hence, it is better to maintain at least 2 hours gap between the administration of Propranolol and these products.
Drug-Disease Interactions: Propranolol should not be given to the people with diabetes, thyroid disease, asthma, cardiogenic shock (when the heart fails to pump required blood to the body), heart valve problem (stenosis), low blood pressure (hypotension), coronary heart disease, liver disease or heart failure.

Patients Concern
Disease/Condition Glossary
Blood pressure: Blood pressure is the measurement of the force that our heart uses to pump blood to all parts of the body. Hypertension is a chronic condition when blood pressure and heart workload are too high. This condition can lead to hardened arteries (blood vessels), decreasing the blood and oxygen flow to the heart. Raised blood pressure can cause chest pain (angina) and heart attack (when blood supply to the heart is blocked). Additionally, high blood pressure also causes brain damage (stroke) and kidney failure. High blood pressure can be diagnosed with the help of a blood pressure monitor or sphygmomanometer. Systolic pressure is the pressure when the heart pumps blood out. On the other hand, diastolic pressure is the pressure when your heart is at the resting stage between heartbeats. If your blood pressure is 140/90 mm of Hg, it means the systolic pressure is 140 mm of Hg, and diastolic pressure is 90 mm of Hg. Ideal blood pressure should be between 90/60 mm and 120/80 mm Hg.
