Pharma market in Puerto Rico
A recent article in the Puerto Rico Herald said that nine major Puerto Rico drug manufacturers reported $24.3 billion in sales for the first quarter of this year. The newspaper reported that sales were flat compared with the fourth quarter of 2004, with profits down 4.2%. Some medicines manufactured and packaged in Puerto Rico showed considerable losses during this time period because of competition starting in 2004 from generics in the U.S. market. The best-selling pharmaceutical product from Puerto Rico is Pfizer's Lipitor.
