The company launched the drug on day one of its approval in the following countries: Germany, Sweden, Denmark, Portugal, the Netherlands, the UK and Austria. Roll out of the drug in Italy, Greece and France will follow as soon as pricing and reimbursement issues are resolved [412240], [412357]. By January 2001, the product was still under review and the company anticipated approval during the first half of 2001 in both the US and Europe [396802].
