New French study showed that the impotence pill Cialis tripled successful intercourse attempts and worked even in men with spinal cord injuries who seem to be often affected by erectile dysfunction.

About 25 % of men with such injuries are capable of having sex and the new drug supposedly has the potential to increase that number. Cialis and similar drugs work by increasing blood flow to the genitals. The study was, however, not independent but funded by Eli Lilly and Co, maker of tadalafil or Cialis.

The study involved 197 men with spinal cord injuries with an average age of 38 from European countries like France, Germany, Italy and Spain. All the men had moderate erectile dysfunction. 142 of men were assigned to the Cialis group while 44 received a placebo for a 12-week period, taking no more than one pill daily before sexual activity. Four months after, Cialis seemed to work nearly half the time they attempted intercourse while those men from the placebo group succeeded only 16.8 % of the time.

Results from the Cialis study were pretty much the same as the results from studies of Pfizer Inc.'s Viagra or sildenafil and Glaxosmithkline Plc's Levitra or vardenafil. All the drugs were found to successfully improve erections in men with impotence after spinal cord injury.
