英文回答：
SSRIs (Selective Serotonin Reuptake Inhibitors)。

SSRIs are a class of antidepressant medications that are used to treat a variety of mental health conditions, including depression, anxiety, and obsessive-compulsive disorder (OCD). SSRIs work by selectively inhibiting the reuptake of serotonin, a neurotransmitter that is involved in mood regulation. By increasing the levels of serotonin in the brain, SSRIs can help to improve mood, reduce anxiety, and relieve symptoms of OCD.
SSRIs are generally well-tolerated, with the most common side effects being nausea, diarrhea, and headache. These side effects typically subside within a few weeks of starting treatment. SSRIs are also relatively safe in overdose, which makes them a good choice for people who are at risk for suicide.
SSRIs are not effective for everyone, and they may not be the best choice for people who have certain medical conditions, such as bipolar disorder or seizure disorder. It is important to talk to your doctor to determine whether SSRIs are right for you.
How SSRIs Work.
SSRIs work by blocking the serotonin transporter, a protein that is responsible for reabsorbing serotonin from the synaptic cleft back into the presynaptic neuron. This allows serotonin to remain in the synaptic cleft for a longer period of time, which leads to increased activation of postsynaptic serotonin receptors.
Serotonin is a neurotransmitter that is involved in a variety of brain functions, including mood regulation, appetite, and sleep. By increasing the levels of serotonin in the brain, SSRIs can help to improve mood, reduce anxiety, and relieve symptoms of OCD.

SSRI类药物的工作原理。

SSRI类药物通过阻断血清素转运蛋白起作用，血清素转运蛋白是一种负责将血清素从突触间隙再吸收回突触前神经元的蛋白质。

这允许血清素在突触间隙中停留更长的时间，这导致突触后血清素受体的激活增加。

血清素是一种参与多种脑功能的神经递质，包括情绪调节、食欲和睡眠。

通过增加大脑中血清素的水平，SSRI类药物可以帮助改善情绪、减轻焦虑并缓解强迫症的症状。

SSRI类药物可有效治疗多种心理健康疾病，包括：
抑郁症。

焦虑症。

强迫症（OCD）。

惊恐障碍。

社交焦虑症。

创伤后应激障碍（PTSD）。

SSRI类药物通常耐受性良好，最常见的副作用包括：
