Activate the release of renin, an enzyme found in your kidneys.The beta-1 receptors are found mainly in the heart and kidneys. What do beta receptors control?īeta receptors come in three different sub-types and have different functions depending on their location. Adrenaline can activate all adrenergic receptors, much like a building master key can open every lock inside that structure.īeta-blockers are beta receptor antagonists, meaning they block beta-adrenergic receptors and slow down certain types of cell activity. They get their name from adrenaline (also called epinephrine), a neurotransmitter that your body produces naturally. Antagonists reduce the number of receptors that are available for activation, which slows down cell activity.Īdrenergic receptors (sometimes called adrenoceptors) are a key type of receptor found throughout your body. The broken part of the key stays in place and blocks another key from entering. The effect is similar to breaking a key after inserting it into a lock. These medications attach to the receptor sites but don’t do anything else.This can stimulate cells that wouldn’t be active otherwise. In effect, they pretend to be the right kind of chemical compound and the cell falls for the deception. These medications attach to and activate receptor sites.Medications that work like this fall into two categories: Many medications work by artificially affecting that chemical signaling process. If your body needs certain cells to act, it can produce more of the chemical that can activate the cells’ receptors. How the cell responds depends on where it is and what it does. If a chemical with the right structure latches onto a receptor, it works like a key and activates the cell to respond a certain way. This uses specific sites on the surface of your cells, called receptors, where certain chemicals - called neurotransmitters - can latch on. Your body uses a chemical signaling system to control certain processes and functions. They also are sometimes used to treat conditions related to your brain and nervous system. Beta-blockers are a class of medicines commonly used to treat a wide range of problems involving your heart and your circulatory system.
