  document.writeln('Prozac was the first of a new class of drugs, called selective serotonin reuptake inhibitors (SSRIs), to be approved for use in the United States. This new type of medication helps patients with depression by increasing the availability of serotonin in the brain. Scientists believe serotonin affects many types of activity in the brain, including the regulation of mood.<br><br>\
  Prozac was initially approved for treatment of depression in Belgium in 1986 and in the United States in 1987. Since then, it has been approved and marketed in more than 90 countries and used by more than 40 million people worldwide.<br><br>\
  The safety and effectiveness of Prozac have been thoroughly studied in clinical trials with more than 11,000 patients. There have been more than 3,500 publications on Prozac in medical/scientific journals<br><br>');
