<p>
For the ingredient name (IN) and trade name (BN), the BN is derived from <ahref="http://www.fda.gov/Drugs/InformationOnDrugs/ucm142438.htm"title="FDA Trade Name"target="_blank">FDA Trade Name</a>, and is the same as IN in most cases. In cases where they
differ, such as extended release variants with something similar to <em>XL</em> in the trade name, that component of the IN is not in the BN.
