Pfizer Inc on Tuesday reported better-than-expected quarterly results, helped by a rebound in sales in emerging markets.

The largest U.S. drugmaker said it earned $6.32 billion, or 86 cents per share, in the fourth quarter. That compared with $1.44 billion, or 19 cents per share, in the year-earlier quarter.
