New GPC Inc.’s roots date back to the 1920s when Bookers Drug Store was formed to manufacture the principal proprietary medicines which, up to that time, had all been imported into then British Guiana. The Company’s product line quickly expanded to include products such as Limacol and Ferrol, which were immediate successes in local and international markets. Over the years, these and many other company products became household names in Guyana and the Caribbean.
