GlaxoSmithKline makes vaccines, prescription drugs and health care products for the general public, according to GSK.com. It is headquartered in the United Kingdom, but it operates globally. Its best-selling products, as of 2014, include Lovaza, Flovent, Advair, Lamictal, Augmentin and Avodart, states the International Business Times.
GlaxoSmithKline resulted from a merger of Glaxo Wellcome and SmithKline Beecham on Jan. 1, 2001. However, the origin of any of the combined companies goes back to 1715, with the opening of Plough Court Pharmacy, GSK.com indicates. John K. Smith, Thomas Beecham, Mahlon Kline, and Henry Wellcome all had their own enterprises at various points. In 1873, entrepreneur Joseph Nathan founded his own company. After many mergers and acquisitions, it became Glaxo . The Nathan directors registered the "Glaxo" trademark in 1906.
GlaxoSmithKline manufacturers a wide range of medications to treat acute and chronic conditions, reports the New York Times. It also makes more than 30 travel vaccines and produces consumer health care products in four categories: nutrition, skin health, oral health and wellness. Some of its consumer health care brands include Aquafresh, Polident and Abreva. The company has operations in the United States, the United Kingdom, Belgium and China. Forbes lists GlaxoSmithKline as the sixth-largest drug company in the world for 2014, as the International Business Times notes.
