Quack doctors used to sell patent medicines which, they claimed, could cure just about any symptoms-- from headaches, to upset stomachs, to baldness, to infection, and on and on. Would such cure-all medicine go against the lock-and-key model of drug action? Why or why not?
Thank you for the opportunity to help you with your question!
if you are presuming that all the different illnesses involved different biochemical pathways (which they generally do), then yes, it would go against the lock-and-key model. The cure-all would have to be some sort of skeleton key that could fit all the different locks. That's asking a lot of for any medicine to do.
Please let me know if you need any clarification. I'm always happy to answer your questions.
