So many pharmaceutical agents are available in the market and we do not know which one to use in daily practice. For example, in the class of anticholinergics there are 8 different original drug preparations. On the other hand, the market has been overflown by generics. Are all ciprofloxacines  in the market (more than 40) equally safe and effective? What are the evaluation criteria? What are the selection criteria? The speakers will answer all the above questions through brief presentations and plenty of discussion that will follow.
