Two boxes with the new anti-impotence drug Cialis (tadafil) are pictured in
a Munich pharmacy February 4, 2003. Cialis has gone on sale in several
European markets this week, spelling the end of Viagra's five-year market
monopoly. The company Eli Lilly is hoping to cash in on the market that
helped propel sales of Viagra, which launched five years ago, to more than
$2.83 billion. REUTERS/Michael Dalder REUTERS
