  == Major changes needed == Hey Wikipedians. I just marked this article as {{cleanup-rewrite}} because, frankly, the quality of the article is terrible. This should probably be a task for WikiProject Pharmacology to take on with full force and extreme prejudice. Random bold and strike-out? Sentence fragments and run-ons? This is not how Wikipedia operates. I urge anyone who can work on this to do so, even if you can improve only one section.  talk
