With big pharma concentrating on Biotechnology this month, February saw no grand gestures in the Pharmaceutical M&A market. Impax Laboratories (NASDAQ: IPXL) acquired the U.S. rights to AstraZeneca’s (NYSE: AZN) migraine headache drug, Zomig. It is sold as a tablet, disintegrating tablet and a nasal spray. Impax paid $130.0 million outright for these rights, which works out to 0.8x 2011 U.S. sales of the drug. It will also pay AZN royalties on sales going forward.

One possible target would be Pfizer’s (NYSE: PFE) animal health unit, valued at between $15.0 billion and $20.0 billion. Naturally, other buyers such as Novartis (NYSE: NVS) are also interested.
