Then, there are antagonists that slow down the amount of neurotransmitters, either because they destroy neurotransmitters or they make it hard to create more.

然后， 有一些拮抗剂会减慢神经递质的数量，因为它们会破坏神经递质或使它们难以产生更多。

So, that said, beta-2-adrenergic antagonists, also known as beta blockers, and alpha-adrenergic agonists, both cause a shift in potassium out of the cells and into the blood.

所以就是说，β2肾上腺素受体拮抗剂，又叫β受体滞剂，还有α受体激动剂，都会使钾离子出细胞而入血。

Interestingly, one of the most effective antipsychotic drugs, clozapine, is a weak D2 antagonist, suggesting that other neurotransmitter systems like norepinephrine, serotonin, and GABA are involved.

有趣的是，最有效的抗精神病药之一，氯氮平，是一种弱D2受体拮抗剂；这提示其它神经递质系统，比如去甲肾上腺素、5-羟色胺、γ-氨基丁酸也与疾病有关。

Antidepressants are the most common choice of medication, specifically selective serotonin reuptake inhibitors or SSRIs, serotonin-norepinephrine reuptake inhibitors or SNRIs, as well as benzodiazepines, and beta-blockers.

抗抑郁药是最常用的药物，尤其是选择性5-羟色胺再摄取抑制剂（SSRIs），5-羟色胺和去甲肾上腺素再摄取抑制剂（SNRIs）还有苯二氮䓬类药物和β-受体拮抗剂。

This increased dopamine helps explain why neuroleptics, which are dopamine receptor antagonists, and tetrabenazine which depletes dopamine, are used to treat chorea in patients with Huntington disease.

Medications include antacids, which neutralise acidity of gastric secretions, and proton pump inhibitors, as well as H2 receptor blockers, which decrease hydrochloric acid production in the first place.

药物包括能中和胃酸的抗酸药、质子泵抑制剂，以及H2受体拮抗剂，它们首先会减少盐酸的产生。

To address this potential problem, scientists developed NMDA receptor antagonist called Memantine, which works by blocking NMDA receptors and thus limiting calcium influx into the neuron.

为了解决这个潜在的问题，科家开发了一种叫做NMDA受体拮抗剂美金刚，它通过断NMDA受体从而限制钙进入脑神经元。

Along the same lines, drugs that reduce the effect of aldosterone can also cause hyperkalemia, and these are drugs like renin inhibitors, ACE inhibitors, angiotensin II receptor antagonists, selective aldosterone blockers, and potassium-sparing diuretics.

According to the earlier mentioned book, 90 out of 91 clinical trials found that opioid antagonists like Naltrexone are effective if extinction is possible, that is if a substance-addicted person can use the opioid antagonist medication and use the substance.

据之前提到那本书称，在 91 项临床实验中，有 90 项研究发现，如果存在“灭绝”可能，纳曲酮之类的阿片拮抗剂都能生效，“灭绝”的意思是，患者能同时服用阿片拮抗剂以及使其成瘾的那种物质。
