Beta Blockers: Types, Side Effects, Interactions. Beta- blockers, also known as beta antagonists, beta- adrenergic blocking agents, or beta- adrenergic antagonists, are drugs that are prescribed to treat several different types of conditions, including hypertension (high blood pressure), angina, some abnormal heart rhythms, heart attack (myocardial infarction), anxiety, migraine, glaucoma, and overactive thyroid symptoms. The sympathetic nervous system activates the . It is part of the autonomic nervous system.

Which one a patient is prescribed will depend on his/her condition. Noradrenalin is released by the nerves when they are stimulated - it is a chemical that conveys messages to other parts of the body, including muscles, blood vessels and the heart. For people with angina, heart failure, or after a heart attack, reducing the heart's workload is crucial. Blood still gets to all parts of the body, but at reduced pressure. The medication lowers the production of fluid inside the eye ball (aqueous humor). For the following people, beta- blockers should be used with caution: Patients with diabetes, especially those with regular episodes of low blood sugar (hypoglycemia) Patients with MG (myasthenia gravis) Patients with a slow heart rate (bradycardia) Patients with low blood pressure (hypotension) Patients with hypertension that results from an adrenal gland tumor (pheochromocytoma) Patients with high blood acid levels (metabolic acidosis) Patients with Prinzmetal angina. Pregnancy and breastfeeding - in some cases certain types of beta- blockers may be used. Suddenly ceasing beta- blocker treatment may exacerbate the patient's condition, especially after a heart attack or for the treatment of angina. Hypertension - beta-blockers lower blood.
