Beta 2 blocker. Beta 2 blockers cease action of beta-2 receptor by blocking the receptor and preventing it from being activated. Similar to beta-1 receptor, the activated beta-2 receptor will lead to the detach of alpha subunit of Gs protein and attachment of adenylate cyclase. Adenosine triphosphate(ATP), is then catalyzed to form cAMP.

Beta blocker. Skeletal formula of propranolol, the first clinically successful beta blocker. Beta blockers, also spelled β-blockers, are a class of medications that are predominantly used to manage abnormal heart rhythms ( arrhythmia ), and to protect the heart from a second heart attack after a first heart attack ( secondary prevention ). [1]
Propranolol, sold under the brand name Inderal among others, is a medication of the beta blocker class. It is used to treat high blood pressure, a number of types of irregular heart rate, thyrotoxicosis, capillary hemangiomas, performance anxiety, and essential tremors, as well to prevent migraine headaches, and to prevent further heart problems in those with angina or previous heart attacks.
Carvedilol is a nonselective beta blocker and alpha-1 blocker. How it improves outcomes is not entirely clear but may involve dilation of blood vessels. Carvedilol was patented in 1978 and approved for medical use in the United States in 1995. It is on the World Health Organization's List of Essential Medicines.
Labetalol is a beta blocker, or an antagonist of the β-adrenergic receptors. It is specifically a non-selective antagonist of the β 1 - and β 2 -adrenergic receptors. [13] Labetalol has intrinsic sympathomimetic activity. [13] It is also an antagonist of the α 1 -adrenergic receptor, and hence is additionally an alpha blocker.
More lipophilic beta blockers tend to cross the blood–brain barrier more readily, with greater potential for effects in the central nervous system as well as associated neuropsychiatric side effects. Metoprolol binds mainly to human serum albumin with an unbound fraction of 0.88. It has a large volume of distribution at steady state (3.2 L/kg ...
