| 설명 | 협심증은 심장동맥의 혈류를 좋게하거나 심장이 혈류에 비해서 많은 일을 하는 것을 억제함으로써 치료될 수 있다. ① nitrate계통의 약물: 혈관을 이완시키는 작용을 함으로써 심장동맥의 혈류를 좋게 한다. ② 칼슘통로차단제(verapamil, nifedipine): 모든 근육의 수축에는 Ca이 관여한다. 즉 Ca이 있어야만 근육의 수축이 가능해진다. 그러므로 Ca이 세포속으로 들어가는 것을 억제하는 약제는 근육의 수축을 막는다. 이 약은 심장의 근육에 작용하여 심장 근육의 수축을 억제하며 심장이 과도하게 일하는 것을 막고, 또 심장동맥의 수축에 관여하는 근육에 작용을 하여 심장동맥을 이완시켜서 혈류를 좋게 한다. ③ 베타차단제(beta-blocker): 신체의 운동량이나 기타의 요구에 의해서 심장을 빨리 뛰게하는 신경은 바로 베타-교감신경이다. 교감신경계란 사람이 위급한 상황에서 작용하는 자율신경계이다. 즉 사람이 긴장하거나 싸울 경우에 전형적으로 교감신경계가 작용한다. 즉 심장이 뛰거나 소화가 않되거나 동공이 커지는 것 따위가 바로 교감신경계의 역할이라고 할 수 있다. 이 교감신경계에서 말초장기에 보내는 신경이 교감신경이다. 그러므로 심장에서 심장을 신체에 필요에 따라서 많은 일을 하게하는 신경을 차단할 경우에는 협심증을 치료할 수 있게 된다(심장의 산소나 기타 영양분의 수요를 줄인다). |

| adrenergic receptors | Reactive components of effector tissues, most of which are innervated by adrenergic postganglionic fibres of the sympathetic nervous system. Such receptor's can be activated by norepinephrine and/or epinephrine and by various adrenergic drugs; receptor activation results in a change in effector tissue function, such as contraction of arteriolar muscles or relaxation of bronchial muscles; adrenergic receptor's are divided into alpha-receptor's and beta-receptor's, on the basis of their response to various adrenergic activating and blocking agents. Synonym: adrenoceptor, adrenoreceptors. (05 Mar 2000) |

| adrenergic uptake inhibitors | Drugs that block the transport of adrenergic transmitters into axon terminals or into storage vesicles within terminals. The tricyclic antidepressants (antidepressive agents, tricyclic) and amphetamines are among the therapeutically important drugs that may act via inhibition of adrenergic transport. Many of these drugs also block transport of serotonin. (12 Dec 1998) |
| alpha-adrenergic blocking agent | An agent that competitively blocks alpha-adrenergic receptors; used in the treatment of hypertension. Synonym: alpha-blocker. (05 Mar 2000) |
| alpha-adrenergic receptors | Adrenergic receptor's in effector tissues capable of selective activation and blockade by drugs; conceptually derived from the ability of certain agents, such as phenoxybenzamine, to block only some adrenergic receptor's and of other agents, such as methoxamine, to activate only the same adrenergic receptor's. Such receptor's are designated as alpha-receptors. Their activation results in physiological responses such as increased peripheral vascular resistance, mydriasis, and contraction of pilomotor muscles. (05 Mar 2000) |
| beta-adrenergic blocking agent | A class of drugs that compete with beta-adrenergic agonists for available receptor sites; some compete for both b1 and b2 receptors (e.g., propranolol) while others are primarily either b1 (e.g., metoprolol) or b2 blockers; used in the treatment of a variety of cardiovascular diseases where beta-adrenergic blockade is desirable. Synonym: beta-adrenergic receptor blocking agent, beta-adrenoreceptor antagonist, beta-blocker. (05 Mar 2000) |

| beta-adrenergic receptor kinase | <enzyme> Cyclic-AMP protein kinase which specifically phosphorylates the agonist-occupied form of beta-adrenergic receptor Registry number: EC 2.7.1.- Synonym: beta-ar kinase, beta-adrenergic receptor kinase 1, g-protein-coupled receptor kinase 2, grk2 (kinase), beta-adrenergic receptor kinase 2, beta-ar kinase 2 (26 Jun 1999) |
| beta-adrenergic receptors | Adrenergic receptor's in effector tissues capable of selective activation and blockade by drugs; conceptually derived from the ability of certain agents, such as propranolol, to block only some adrenergic receptor's and of other agents, such as isoproterenol, to activate only the same adrenergic receptor's. Such receptor's are designated as beta-receptors. Their activation results in physiological responses such as increases in cardiac rate and force of contraction (b1), and relaxation of bronchial and vascular smooth muscle (b2). (05 Mar 2000) |
| receptors, adrenergic | Cell-surface proteins that bind epinephrine and/or norepinephrine with high affinity and trigger intracellular changes. The two major classes of adrenergic receptors, alpha and beta, were originally discriminated based on their cellular actions but now are distinguished by their relative affinity for characteristic synthetic ligands. Adrenergic receptors may also be classified according to the subtypes of g-proteins with which they bind; this scheme does not respect the alpha-beta distinction. (12 Dec 1998) |
| receptors, adrenergic, alpha | One of the two major pharmacological subdivisions of adrenergic receptors. The alpha-beta distinction was originally based on cellular effects of receptor activation but now relies on the relative affinities for certain synthetic ligands. Alpha-adrenergic receptors are further subdivided into several subclasses based on studies of endogenous and cloned receptors. (12 Dec 1998) |
| receptors, adrenergic, alpha-1 | A subclass of alpha-adrenergic receptors (receptors, adrenergic, alpha). Alpha-1 adrenergic receptors can be pharmacologically discriminated, e.g., by their high affinity for the agonist phenylephrine and the antagonist prazosin. They are widespread, with clinically important concentrations in the liver, the heart, vascular, intestinal, and genitourinary smooth muscle, and the central and peripheral nervous systems. (12 Dec 1998) |
| receptors, adrenergic, alpha-2 | A subclass of alpha-adrenergic receptors (receptors, adrenergic, alpha). Alpha-2 adrenergic receptors can be pharmacologically discriminated, e.g., by their high affinity for the agonist clonidine and the antagonist yohimbine. They are found on pancreatic beta cells, platelets, and vascular smooth muscle, as well as both pre- and postsynaptically in the central and peripheral nervous systems. (12 Dec 1998) |
| receptors, adrenergic, beta | One of the two major pharmacologically defined classes of adrenergic receptors. The alpha-beta distinction was originally based on the cellular effects of receptor activation but now relies on the relative affinities for characteristic synthetic ligands. Beta adrenergic receptors are further subdivided based on information from endogenous and cloned receptors. (12 Dec 1998) |
| receptors, adrenergic, beta-1 | A subclass of beta-adrenergic receptors (receptors, adrenergic, beta). Beta-1 adrenergic receptors are equally sensitive to epinephrine and norepinephrine and bind the agonist dobutamine and the antagonist metoprolol with high affinity. They are found in the heart, juxtaglomerular cells, and in the central and peripheral nervous systems. (12 Dec 1998) |
| receptors, adrenergic, beta-2 | A subclass of beta-adrenergic receptors (receptors, adrenergic, beta). Beta-2 adrenergic receptors are more sensitive to epinephrine than to norepinephrine and have a high affinity for the agonist terbutaline. They are widespread, with clinically important roles in skeletal muscle, liver, and vascular, bronchial, gastrointestinal, and genitourinary smooth muscle. (12 Dec 1998) |
