What is propranolol?

Propranolol is a medication that belongs to a class of drugs known as beta blockers. It is commonly used to treat various conditions including high blood pressure, angina, and certain heart rhythm disorders. Propranolol works by blocking the effects of adrenaline on beta receptors in the body, which helps to reduce heart rate and blood pressure.

Propranolol is also used off-label for the treatment of certain anxiety disorders, such as performance anxiety and social anxiety. It can help alleviate symptoms such as trembling, sweating, and rapid heartbeat, which are often associated with anxiety.

How does propranolol work?

Propranolol works by blocking beta receptors in the body. These receptors are responsible for the body's response to adrenaline, a hormone that is released during times of stress. By blocking these receptors, propranolol helps to reduce the effects of adrenaline, thereby slowing down the heart rate and lowering blood pressure.

Additionally, propranolol has been found to have a calming effect on the brain, which can help to reduce anxiety symptoms. It works by inhibiting the reuptake of the neurotransmitter serotonin, which is involved in regulating mood and emotions.

What are the possible side effects of propranolol?

Like any medication, propranolol can cause side effects. The most common side effects include fatigue, dizziness, and cold hands or feet. These side effects are usually mild and go away on their own, but if they persist or become bothersome, it is important to contact a healthcare professional.
