What Are the Different Types of Adrenal Gland Hormones?

Adrenaline (adrenaline, epinephrine, English capital abbreviation: A or E) is a hormone secreted by the human body. When a person experiences certain stimuli (such as excitement, fear, tension, etc.) to secrete this chemical, it can make people breathe faster (providing a lot of oxygen), the heartbeat and blood flow are accelerated, the pupils are enlarged, and more energy is provided for physical activity. Make the response faster. Adrenaline is a hormone and neurotransmitter that is released by the adrenal glands. Adrenaline can increase the contractility of the heart, dilate the blood vessels of the heart, liver, and bones, and constrict the blood vessels of the skin and mucous membranes. It is an essential product for saving dying people or animals. Its biosynthesis is mainly the formation of norepinephrine in medulla chromium cells, and then by the action of phenylethanolamine N-methyl transferase (PNMT), the Into adrenaline.

The Secret of the Flood Force

At the Rio Olympic Games, Chinese swimmer Fu Yuanhui attracted a large number of fans with her candid and humorous personality. The "flooding power" that she blurted out in an interview was more fun for people. In fact, this power comes from adrenaline.

What is adrenaline more

Adrenaline is a hormone secreted by the adrenal medulla. When the human body experiences certain stimuli, such as excitement and fear, it can secrete this hormone, which accelerates heartbeat and breathing, increases blood flow, and increases blood glucose, thereby increasing strength and increasing response speed. Adrenaline can also be used to save patients with cardiac arrest and anaphylactic shock.

Adrenaline is not elixir more

Adrenaline can only temporarily stimulate people's strength, it does not make people really strong, and it can also cause adverse reactions such as increased blood pressure and arrhythmia. In addition, adrenaline can interact with many drugs and cause damage to the human body.

Epinephrine drug description

Epinephrine classification

Circulatory Drugs> Antiarrhythmic Drugs> Treatment of Bradycardia

Epinephrine dosage form

1. Injection: a sterile solution of epinephrine hydrochloride or epinephrine tartrate, containing 1 mg of epinephrine and 8 mg of sodium chloride per milliliter. 1mg (ml), 0.5mg (0.5ml);

2. Oil injection: 2mg (1ml) (for intramuscular injection only).

3. Eye drops: 0.1%, 0.5%, 2%.

Epinephrine pharmacological effects

Epinephrine directly excites the adrenaline and receptors. By exciting the bronchial smooth muscle 2 receptors, it can relieve bronchospasm, relax the bronchi, improve the ventilation function, and inhibit the release of allergic mediators, produce asthma effects, and also inhibit the endothelial permeability Sexual increase, promote mucus secretion and cilia movement, promote alveolar type cells synthesis and secretion of surfactants. At the same time, the alpha receptors in the bronchial mucosa are excited, causing excessive contraction of the mucosal blood vessels and increased capillary pressure, which may lead to increased mucosal edema and hyperemia and weaken the asthma effect. Cardiovascular 1 receptor excitement can strengthen myocardial contractility, increase heart rate, and increase cardiac output. In addition, there are still effects of increasing basal metabolism, raising blood sugar and dilated pupils. Its bronchodilator effect is strong and rapid, but relatively short. Subcutaneous injection of 0.25 to 0.5 mg, which takes effect for 10 to 15 minutes, and maintains the effect for 1 to 2 hours. Because of its many adverse reactions, it has rarely been used as an asthma treatment in clinical practice, and is only used in severe bronchial asthma, especially in the acute attack of allergic asthma. Inhaled by a quantitative aerosol, the bronchodilator effect is weak and transient.

Epinephrine pharmacokinetics

Little oral absorption. After oral administration, the local vascular contraction of the digestive tract reduces absorption, and the absorbed part can be rapidly degraded by the enzyme in the gastrointestinal tract and metabolized in the liver. It cannot reach an effective concentration, so oral administration is not effective. It is effective 3 to 5 minutes after subcutaneous injection, and the effect can be maintained for about 1 hour. Because the subcutaneous blood vessels can be contracted, the maintenance time is longer, and the absorption is delayed, it is generally appropriate to use subcutaneous injection. Intramuscular injection absorbs quickly and has a strong effect, but only lasts for 10-30 minutes. After injection, it is rapidly metabolized and inactivated by catechol oxygen methyltransferase (COMT) and monoamine oxidase (MAO) in blood and tissues. The metabolite 4-hydroxy-3-methoxymandelic acid Excreted mainly by urine.

Epinephrine

Adrenaline use

This product directly acts on adrenergic and receptors, and produces strong and rapid and short-term excitation of and -type effects. Excitation of cardiac 1-receptors can increase myocardial contractility, increase heart rate and myocardial oxygen consumption increase. At the same time, it acts on vascular smooth muscle 2-receptors, which dilates blood vessels, reduces peripheral vascular resistance and reduces diastolic blood pressure. Exciting 2-receptors can relax bronchial smooth muscles, dilate the bronchi, and relieve bronchospasm. Exciting -receptors can shrink the skin, mucosal blood vessels, and small visceral vessels. It is mainly used for cardiac arrest, bronchial asthma, anaphylactic shock, and can also treat urticaria, hay fever, and nasal mucosa or gum bleeding.

Physiological effect

Adrenaline generally increases the contractility of the heart; blood vessels in the heart, liver, and bones dilate and blood vessels in the skin and mucous membranes shrink. In medicine, epinephrine is used to stimulate the heart when the heart is stopped, or to dilate the trachea when asthma. It has a contraction effect on the blood vessels of the skin, mucous membranes and internal organs (such as the kidneys); it has a dilation effect on the coronary arteries and skeletal muscle blood vessels. Because it can directly act on coronary vessels to cause vasodilation and improve heart blood supply. Utilizing its effects of exciting heart contraction blood vessels and relaxing bronchial smooth muscles, it can relieve symptoms such as weak heartbeat, decreased blood pressure, and difficulty breathing. Adrenaline can stimulate both alpha and beta receptors, producing strong alpha and beta effects.

The heart acts on the 1 receptors of the myocardium, the conduction system, and the sinoatrial node, strengthening myocardial contractility, accelerating conduction, accelerating heart rate, and increasing myocardial excitability. The effect on isolated myocardium is characterized by an accelerated rate of contractile development (positive contractile effect).

Clinical application

Rescue for cardiac arrest and anaphylactic shock can also be used for the treatment of other allergic diseases (such as bronchial asthma, urticaria). Combination with local anesthetics is beneficial for local hemostasis and prolonged efficacy.

Adrenaline indication

1. Early epinephrine solution eye-dropping is used to treat primary open-angle glaucoma and secondary open-angle glaucoma. The mechanism of lowering intraocular pressure is not fully understood, and it is considered to be related to reducing the secretion of aqueous humor and improving the coefficient of aqueous humor . Adrenaline has a lower therapeutic index for reducing intraocular pressure. The effect of reducing intraocular pressure is proportional to its concentration. However, the increase in concentration is accompanied by the increase of side effects caused by systemic absorption. Therefore, it has rarely been applied to the treatment of glaucoma.

2. Mydriasis: It often uses its dilation effect and cocaine and atropine to form a dilated pupil mixture to maximize the dilation effect to combat iris adhesion and is used to treat iris inflammation and eye trauma. It can also be used in combination with miotic agents in the treatment of glaucoma to prevent post-iris adhesions and pupil sphincter spasm and pupil block, and reduce the side effects of long-term pupil dilation.

3. Vasoconstrictive effect: Utilizing its vasoconstrictive effect, using solution drops to constrict the bulbar conjunctival vessels can identify bulbar conjunctival congestion and ciliary congestion and scleral congestion; external or intraoperative surgery can reduce bleeding in the surgical field, but It is not effective for larger blood vessels; adding a small amount of epinephrine to a local anesthetic can prolong the action time of local anesthetics, reduce the amount of local anesthetics, and reduce its systemic absorption ^[2] .

Adrenaline release

It is used to regulate myocardium, increase hypertension, activate sympathetic nerves, transport glucose to muscles, and promote muscle activity to cope with stress or danger. It can instantly give people powerful functions to boost and horrific explosive power, but if the secretion is too high than the body Tolerable limit, it will make the pores and blood vessels tighten, and even block the adverse effects of transporting blood to the heart, palpitations, headaches, agitation, nausea or physical disturbances.

Adrenaline Expert Reviews

Due to the many adverse effects of epinephrine, it is rarely used as an asthma drug in clinical practice. Epinephrine is an adrenaline (, ) agonist. For clinical cardiac resuscitation, anaphylactic shock, and cardiac arrest, adrenaline is generally preferred. Can excite myocardium, increase hypertension, and quickly relieve symptoms. Use of commonly used doses can increase systolic blood pressure and diastole increases as doses increase. Epinephrine also relaxes the bronchial smooth muscles, dilates the bronchi, and relieves bronchospasm. Therefore, the clinical application of bronchial asthma is significant. Epinephrine can excite both the alpha receptor and the beta receptor, shrink the blood vessels, enlarge the pupils, reduce the production of aqueous humor, make the aqueous humor drain easily, and reduce the intraocular pressure. The effect of reducing intraocular pressure is directly proportional to its concentration, but the increase in concentration is accompanied by an increase in adverse reactions caused by systemic absorption. Therefore, it has rarely been used in the treatment of glaucoma clinically ^[2] .
