PharmaceuticalsOutside the United States
Outside the United States, we promote our pharmaceutical products primarily through sales representatives. While the products marketed vary from country to country, neuroscience products constitute the largest single group in total sales. Distribution patterns vary from country to country. In most countries,
we maintain our own sales organizations, but in some countries we market our products through independent distributors.
