*CORRECTION: In our benzodiazepine versus barbiturate mnemonic, the idea is that benzodiazepines and barbiturates both act as positive allosteric modulators of the GABA receptor. However, benzos increase the frequency of opening of the channel while barbiturates increase the duration of channel opening. In fact there is no consistent difference between the drug classes in regards to dosing timing. That’s my mistake! I didn’t fully understand this particular mnemonic when describing it!

Do you have a mnemonic you think is really useful? PLEASE SHARE IT in the comments section below! Watch this quick-fire video to see some of the best mnemonic devices we use to DOMINATE the ABSITE!
