Long story short, you can block opioid receptor activation with something called an opioid antagonist.

简而言之，我们以通过服用一种名叫“阿片拮”药物来阻止阿片受体激活。

Beta blockers can help ease the physical symptoms of performance anxiety.

而β-受体拮以缓解表现焦虑躯体症。

Rimonabant is an endocannabinoid antagonist — it's an " anti-marijuana" medicine, which also means it's " anti-munchies" medicine.

利莫那班是一种内源性大麻素拮——这种药物具有“大麻”作用，换句话说，它具有“点心（诱惑）”作用。

As you'd expect from an opioid antagonist, Naltrexone has been used to try and treat opiate addiction.

和普通阿片拮一样，纳曲酮一直被用来治疗阿片成瘾。

Individuals with more severe forms of asthma might need additional treatments like daily corticosteroids, long-acting beta-adrenoceptor agonists, or leukotriene antagonists.

哮喘较为严重患者能需要额外治疗，日服皮质类固醇，施用长效β肾上腺素受体激动或白三烯拮。

So, for instance, there is a drug known as Curare and Curare is an antagonist.

因此，例，有一种名为箭毒药物，而箭毒是一种拮。

Caffeine is what's called an adenosine receptor antagonist.

咖啡因是所谓腺苷受体拮。

The AMI comprises two muscles that are surgically connected, an agonist linked to an antagonist.

AMI 包括两块通过手术接肌肉，一条与拮相动肌。

When the agonist contracts upon electrical activation, it stretches the antagonist.

当激动因电激活而收缩时，它会拉伸拮。

Now, let's move onto our next drug class that is NMDA receptor antagonist.

现在，让我们进入下一个药物类别，NMDA受体拮。

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.

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

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.

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

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.

多巴胺水平增高解释了为什么神经抑制-多巴胺受体拮和丁苯那嗪（中枢多巴胺耗竭）被用来治疗亨廷顿病患者舞蹈症。

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，又叫β受体阻滞，还有α受体激动，都会使钾离子出细胞而入血。

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， 有一些拮会减慢神经递质数量，因为它们会破坏神经递质或使它们难以产生更多。

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酸药、质子泵抑制，以及H2受体拮，它们首先会减少盐酸产生。

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.

为了解决这个潜在问题，科学家开发了一种叫做NMDA受体拮美金刚，它通过阻断NMDA受体从而限制钙进入大脑神经元。

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.

同理，以降低醛固酮效能药物也以导致高钾血症，例肾素抑制、ACE抑制、血管紧张素II受体拮、选择性醛固酮受体阻滞以及保钾利尿等。

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，果存在“灭绝”能，纳曲酮之类阿片拮都能生效，“灭绝”意思是，患者能同时服用阿片拮以及使其成瘾那种物质。
