With the trend of increasingly abundant free online university courses, the
university of Pennsylvania now offers a basic course of 4-5 weeks on
Pharmacology starting in June. See https://www.coursera.org/
It may help understand how drugs work in principle and how therapies get
developed and what the future opportunities and current limitations are.
I'm also following this online university course myself to become a better
talking partner for my doctors.
