What is an adrenergic agonist?

Adrenergic agonist, sometimes referred to as a sympathomimetic agent, is a drug that affects what is called a nice nervous system, prepares the body in need. The heart rate accelerates, the airways spread, the blood is diverted from the skin to the muscles and the bladder and the intestine has become less active. From a medical point of view, the treatment of conditions such as asthma, allergy, cardiac arrest or shock may be used by an adrenergic agonist.

Adrenergic agonists can cause their effects to connect directly to what is called adrenergic receptors at nerve endings or cells, or they could indirectly increase the amount of norepinephrine. Norepinephrine, or noradrenaline, is a neurotransmitter of the sympathetic nervous system, the fabric Messenger, which usually binds to adrenergic receptors. In some cases, the adrenergic receptor agonists can work directly and indirectly., Such as epinephrine or adrenaline. Dopamine is another adrenergic agonist that occurs in the body and which isconverted into noradrenaline. Cocaine and amphetamines occur outside the body and are examples of adrenergic agonists who act indirectly.

6 These receptors could be placed on another nerve end or on cells of body tissue or organ. The binding of an adrenergic agonist to alpha receptors can cause effects such as narrowing of blood vessels supplying intestine and skin or expanding pupils. Activation of beta receptors increases the strength and speed at which the heart beats, expands the blood vessels that give muscles and open the airways. Metabolism is affumed, making more glucose and fatty acids available, and the allergic reaction of the body is dampened.

Adrenergic agonist can be used in the treatment of asthma administered in inhalation form. A severe asthmatic attack causes the muscles in the walls of the airways to withdraw, leading to life at risk. An adrenergic agonist can reverse this narrowing through their relAxic effect on muscles. The drug used will usually be such as albterol or salbutamol, which affects specific types of beta receptors, which are mainly located inside the lungs. This helps to avoid side effects such as fast heart rhythm or fraying muscles that can be experienced with drugs that affect beta receptors throughout the body.
