Verbal Mystery

So. Yesterday I was at the dentist for three hours for the final part of a multipart root canal procedure. With my mouth full of dental tech stuff I cannot really talk so I find it interesting to listen to the conversations going on around me. The dental assistant was telling the dentist about something and I drifted off into my own thoughts when the drill noise made it difficult to hear. When the drill stopped I heard her say apidexin. At first I thought it must be some new type of treatment for appendicitis. Then I realized they were talking about a diet pill. Why is it that pharmaceuticals have such strange names? Oh, the mysteries of life.
