Just a month after Pfizer came under fire for allegedly using strong-arm tactics against a potential key witness in the multidistrict litigation over its Neurontin anti-seizure medication, the pharmaceutical giant lodged a similar complaint against a plaintiffs expert.

In a 12-page brief (pdf) filed Thursday, Pfizer lawyers from Skadden, Arps, Slate, Meagher & Flom and Shook, Hardy & Bacon accused a twice-sanctioned doctor-consultant named David Egilman of attempting to coerce favorable testimony from one of the physicians who treated the alleged victim in the case, Hartley Shearer.
