Drug Battle Sours

NEW YORK -- Warner-Lambert has sued Pfizer, seeking to terminate Pfizer's rights to co-market and share profits from the blockbuster cholesterol-lowering drug Lipitor.

The pill, expected to reap $3.6 billion in 1999 sales, is at the heart of an $80 billion hostile takeover bid that Pfizer Inc. launched against Warner-Lambert Co. last month.

Warner-Lambert, the fastest growing major drug maker, is seeking to merge with American Home Products Corp. in a deal valued at $67 billion.
