Eli Lilly and ICOS have applied to medicine regulators for approval for a daily dose form of Cialis, its successful impotence treatment. The daily dose would be 5 mg. Cialis is currently licensed as an “on demand” medication which is required to be taken at least 30 minutes before sexual activity. The medication is currently licensed in 10 mg and 20 mg doses, with the 20 mg dose being by far the most popular.
A daily dose would allow men suffering from erectile dysfunction a greater degree of spontaneity in the way that they organise their sex lives. A recent double blind trial of the daily dose Cialis found that 50% of men taking Cialis considered their erectile dysfunction to have been cured against only 8% of men on the placebo.
Analysts have suggested that it is unlikely that the daily dose form of the medication will be as popular as the “on demand” version of Cialis as it will inevitably lead to a higher overall cost for patients. Also, Cialis already allows a greater degree of timing flexibility than its competitors as it has a longer period if effectiveness: up to 36 hours compared with around 4 hours for Viagra and Levitra.
