When Is Viagra Going Generic

Description

When researchers first created sildenafil in the 1980s, it was intended to be a treatment for angina, or chest pain caused by reduced blood flow to the heart, according to a 2004 review article.However, in an early trial, the drug did not produce the heart effects the researchers had hoped for. But a number of study volunteers reported an interesting side effect — they had stronger and more persistent erections. Other studies conducted around the same time revealed that sildenafil's molecular target may play a role in erections. That spurred a new study of the drug for men with erectile dysfunction, which found that sildenafil was effective in 82 percent of men who received the highest study dose, according to the review.

DOSAGE

For Use As Needed

  • The recommended starting dose of Cialis for use as needed in most patients is 10 mg, taken prior to anticipated sexual activity.
  • The dose may be increased to 20 mg or decreased to 5 mg, based on individual efficacy and tolerability. The maximum recommended dosing frequency is once per day in most patients.
  • Cialis for use as needed was shown to improve erectile function compared to placebo up to 36 hours following dosing. Therefore, when advising patients on optimal use of Cialis, this should be taken into consideration.

 For Once Daily Use

  • The recommended starting dose of Cialis for once daily use is 2.5 mg, taken at approximately the same time every day, without regard to timing of sexual activity.
  • The Cialis dose for once daily use may be increased to 5 mg, based on individual efficacy and tolerability.
