Final answer:
The correct answer is B) SSRIs. Selective Serotonin Reuptake Inhibitors, such as Prozac, Zoloft, and Paxil, work by increasing serotonin levels to alleviate symptoms of depression without causing happiness or changing personalities.
Step-by-step explanation:
The class of medications that can reduce feelings of sadness and depressed mood but does not make people "happy" or change their personalities, such as SSRIs, are Selective Serotonin Reuptake Inhibitors (SSRIs). Antidepressants like SSRIs do not create a sense of happiness; rather, they work by balancing neurotransmitters in the brain, which can help alleviate the symptoms of depression.
Common SSRIs include drugs like Prozac, Zoloft, and Paxil. These medications increase the level of serotonin in the synaptic cleft by preventing the reuptake of serotonin into the presynaptic neuron. Unlike NSAIDs or benzodiazepines, SSRIs are specifically designed to treat mental health conditions related to depression and anxiety, and do not offer immediate mood elevation or personality changes.
