Pfizer

Let's wrap up this holiday week in business and economic news.

Regulators want to cut down on these deals, but this one is full-speed ahead.

The deal would create the largest pharmaceutical company in the world.

Pfizer, Merck, Microsoft, Apple and others store money overseas for tax advantage.

Viagra is one of the most-counterfeited drugs on the web, and Pfizer's latest effort to tackle that issue is a first.

The charge: violating the U.S. Foreign Corrupt Practices Act. Pfizer's drug sales reps paid bribes to get Pfizer drugs used by doctors in countries like China, Russia and Bulgaria.

Pfizer seems to be weathering the loss of its patent for Lipitor just fine. The drug company says its second quarter profit jumped 25 percent. That's despite lower revenue, and competition from generics for its cholesterol-fighting blockbuster.

Reuters reports Nestle is closing in on a deal to buy Pfizer's infant nutrition business for up to $10 billion. That's a lot of baby formula.

Drug giant Pfizer is asking women around the country to return certain birth control pills under fears they weren't packaged correctly.

Pfizer's big seller, Lipitor, loses its patent this week. But the drug giant isn't ready to give up all those customers just yet.
