Bridget was suffering from depression when the first two classes of antidepressants were developed; if she was prescribed an antidepressant during this time period, it would have been one of which of the following?

A) SSRIs or MAOIs
B) tricyclics or SSRIs
C) tricyclics or MAOIs
D) SSRIs or GABA inhibitors

The first two classes of antidepressants were tricyclics and MAOIs (monoamine oxidase inhibitors). Therefore, if Bridget was prescribed an antidepressant during this time period (before the development of SSRIs), it would have been one of these two classes. Option A (SSRIs or MAOIs) is incorrect because SSRIs were not developed during the time when the first two classes of antidepressants were developed. Option B (tricyclics or SSRIs) is incorrect because SSRIs were not yet developed during that time. Option D (SSRIs or GABA inhibitors) is incorrect because GABA inhibitors are not commonly used as antidepressants.
