Clinical application of receptor blocking drugs, Introduction to receptor blocking drugs

Excuse me: I am a patient with hypertension and heart palpitations, and I am also a patient with chronic rhinitis! Stuffy nose often! If you want to replace metoprolol with highly selective bisoprolol, can it reduce the sympathetic nerves that antagonize the respiratory system?

Receptors can be divided into two subtypes: 1 and 2, so this class of drugs can be divided into 1, 2 receptor blockers, 1 receptor blockers and 2 receptor blockers according to whether they are selective, and their effects are mainly manifested in vasomotor and blood pressure.

Receptor blockers can selectively bind to adrenergic receptors, and they themselves do not excitate or weakly activate adrenergic receptors, but they can prevent norepinephric neurotransmitters and adrenergic receptor agonists from binding to receptors, thereby producing anti-adrenergic effects.

It is mostly used as vasodilators and antihypertensive drugs.

Receptors can be divided into two subtypes: 1 and 2, and the drugs can be divided into two subtypes: 1, 2 receptor blockers, and 1 receptor blockers. The above two subtypes can be further divided into those without intrinsic sympathomimetic activity and those with intrinsic sympathomimetic activity.

This class of drugs can compete with norepinephrgic neurotransmitters or adrenergic receptor agonists for receptors, thereby antagonizing their adrenaline-like effects. In addition to blocking receptors, some drugs also have certain intrinsic activity, which can produce weak agonist receptor effects. In general, due to its weak agonistic effect, the resulting effect is often masked by the blocking effect.

Receptor blockers have been widely used for high blood pressure, effective for mild and moderate hypertension, and can also reduce attacks for patients with hypertension and angina. In addition, it has a good effect on patients with high cardiac output and renin activity, and for patients with cerebrovascular lesions.

Receptor blockade rolling drugs can be used to carry Zheng do:

a.Antihypertensive.

b.Antiarrhythmic.

c.Anti-angina.

d.Antiseptic shock.

e.**Hyperthyroidism is balanced.

Correct answer: abce

a.It can increase the heart rate and increase cardiac output.

b.Sometimes it can trigger or worsen an asthma attack.

c.Promotes the breakdown of fat bidana.

d.Promotes renin secretion.

Correct answer: Sometimes it can induce or add to a purely disturbing asthma attack.

Answer]: Na imitation B

Receptor blockers can block the 2 receptors on the bronchial smooth muscle, causing the bronchial smooth muscle to contract and increase the resistance of the respiratory tract. This effect is weak in normal people, and in patients with bronchial asthma, it can sometimes induce or aggravate acute episodes of asthma.

There are many receptor blocking drugs, and there are dozens of clinical applications

1) Non-selective receptor blockers: i.e. 1 and 2 receptor blockers. Representative drugs include propranolol, timolol, indolol and nadolol.

2) Selective 1 receptor blockers: representative drugs include atenolol, metoprolol, esmolol and acebutolol.

3), receptor blocker: labetalol (salsamine benzyl cardiodine).
