Is your drug project a 505(b)(2), ANDA or OTC?

I get a lot of requests to assure people that their project is, or is not, a 505(b)(2).  A few questions about whether it is an OTC candidate. The question about whether the proposed drug is a 505(b)(1) or 505 (b)(2) is readily answered by the question: is any data essential for approval being obtained from a public source? If the answer is yes, then it is a 505(b)(2).  Is it an OTC?  The FDA has a decision tree (see thumbnail) might be helpful.  This same chart does a nice job differentiating a 505(b)(2) from an ANDA (505j).
