Meth-resistant PSE

ST. LOUIS — Westport Pharmaceuticals has been showcasing its Zephrex-D "meth-resistant" pseudoephedrine-based decongestant that is now available in retail stores throughout Missouri. It's a hot product as much for the sales generated, as for the sales not lost.

Sales of the top four PSE products almost reached $400 million in calendar 2012, up around 8% versus comparable 2011 PSE sales. But that's not the only sales figure retailers will be tracking — stocking Zephrex-D means less shrink in ancillary meth-producing supplies as meth cooks source their PSE elsewhere.
