Hey man, first off good job on exploring another avenue of pharmacy that isn't pursued much around here. It's actually a very fulfilling position, and having a prof who actually wants to teach the material is always a win/win for students and profs alike.
It doesn't seem like many people here have ever taught or want to (e.g. WVU's largely bitter experience with academia), but I've personally loved it.
I've had opportunity to teach pharmacology to 2nd year pharmacy students at a university here in Canada.
General advice would be get to know the people currently teaching it. Make an appointment to see them, take them out for a coffee if they're a former prof, etc., and show them your interest. I was fortunate in that a former prof of mine who knew I had a keen interest in pharmacology (I volunteered in his lab), was very generous and basically let me have free reign on a number of lectures. Getting to know them and _Volunteering_ to help out with a few lectures with get your foot in the door and invaluable experience. Then, when you apply for your own course you'll have that (plus a great LOR hopefully) on your resume.
Feel free to PM with more specifics (I don't usually get too detailed on public forums) but I'd be very happy to share some ideas/lectures etc., with you and speak about it in more detail.
I'm actually leaving the profession but I still hope I'll be able to give a few lectures in my free time. Again, props to you for going down a road less traveled but in my experience a road much more rewarding, intellectually and professionally. Perhaps not financially, but to each his own.
