question about 5-HT receptor agonists and antagonists

[myry]

Is it good enough to know, for example, that Mirtazapine blocks 5-HT receptors, or do we need to know that it blocks 5-HT2 and 5-HT3 receptors? I see they get more detailed in FA, which surprises me, since we did not cover that in class.

examples I found:

atypical antipsychotics- 5-HT2 antagonist
buspirone- 5-HT1A agonist
ondansetron- 5-HT3 antagonist
sumatriptan- 5-HT1D agonist
mirtazapine- 5-HT2 and 5-HT antagonist


If we need to know specifics, is there any rhyme and reason to it or just memorize?

Thanks!

In the course of my studies I've found that lots of pharm questions can get very nitpicky when it comes to their actions at different 5-HT receptors, so I would know them. Also, whatever's in FA is fair game in my books. As far as drugs are concerned, only agonists act at 5-HT1 receptors. All other drugs acting at 5-HT receptors like 5-HT2 and 5-HT3 are antagonists.
