Pharmaceutical giants Pfizer and GlaxoSmithKline are combining their over-the-counter drugs and healthcare products to create a new joint venture.

The drugs include well-known brands, such as the painkillers Advil and Excedrin, Sensodyne toothpaste, Tums, and the vitamin brands Centrum and Caltrate. The companies plan to finalize the deal in the second half of 2019, and will split off the consumer part of the business after three years, at which point it will become the largest seller of over-the-counter products in the world.
