As biotech investors continue to wait for Arena Pharmaceuticals to launch its obesity drug Belviq, pharmaceutical company Vivus (NASDAQ:VVUS) has been trying to ramp up sales for its rival drug Qsymia. The company's slow drug launch has been the topic of much debate in past quarters, but it recently reported that its total number of prescriptions shipped in March were 42% greater than scripts in January. Should investors be excited about this result, or will the real catalyst for this stock be its upcoming earnings report for the first quarter of 2013? Health-care analyst Max Macaluso sheds light on this topic in the following video.
