Erectile Dysfunction: Oral Therapy Treatment Options

Approval Status: Approved for marketing by the U.S. FDA on August 19, 2003. Chemical/Biological Nature: LEVITRA is a small molecule chemical compound, with a molecular weight of 579.1 daltons. Administration: LEVITRA is taken orally 60 minutes before sexual activity. For most patients, the recommended starting dose is 10 mg.

How effective are vardenafil and tadalafil for erectile dysfunction?

Depending on an individual’s response, the dose may be adjusted higher to 20 mg or lower to 5 mg. The recommended maximum dosing frequency is no more than once daily. Mechanism of Disease: Penile erection is a hemodynamic event. There are many abnormalities that could lead to erectile dysfunction. Normally, the signal transduction events mediated by cyclic guanosine monophosphate (cGMP) lead to the relaxation of the smooth muscle of blood vessels that supply blood to the penis when there is sexual stimulation.

Is Levitra or Viagra more effective?

The lack of, or insufficient sustained levels of, cGMP result in erectile dysfunction. Mechanism of Drug Action: During sexual stimulation, nitric oxide is released from nerve cells and subsequently from the endothelial cells in the corpus cavernosum of the penis. Nitric oxide activates guanylate cyclase, which catalyzes the synthesis of cGMP from guanosine triphosphate (GTP). cGMP causes the smooth muscle to relax, allowing increased blood flow into the penis, leading to an erection. Because of its importance, the level of cGMP is tightly regulated.

The balance is maintained by production and degradation. As mentioned above, production of cGMP is initiated after nitric oxide is released. There are numerous types of PDEs, with each type being preferentially expressed in different tissues. The predominant type expressed in the penis is PDE type 5 (PDE5). LEVITRA binds selectively to PDE5 and inhibits the enzymatic function of PDE5. Viagra and Levitra may cause mild side effects in some people.

Overdose/Missed Dose

Less cGMP is degraded, tilting the balance to a higher level of cGMP, thus enhancing penile erection. It was demonstrated by in vitro studies that LEVITRA inhibits PDE5 selectively. LEVITRA’s inhibitory effect on PDF5 is many more times than that of other PDE types (1, 2, 3, 4, 6, 7, 8, 9, 10, and 11). LEVITRA’s therapeutic effect is contingent on the presence of a sexual stimulation; no sexual stimulation, no release of nitric oxide from nerve endings, and so no effect by LEVITRA. Efficacy and Benefits: Four double-blind, randomized, fixed-dose, multicenter trials involving 2,431 patients were conducted to evaluate the efficacy of LEVITRA.

Two trials were conducted with general ED patients, one trial with ED/diabetes patients and one trial with ED/post-prostatectomy patients. The fixed doses were 5 mg, 10 mg, and 20 mg daily. Primary endpoints were evaluated at 3 months during the trials. For all four trials, the primary endpoints were Erectile Function (EF) Domain score and two aspects of the Sexual Encounter Profile (SEP), i.e., the ability to achieve vaginal penetration (SEP2) and the ability to maintain an erection long enough for successful intercourse (SEP3). For the trial involving 762 general population ED patients at the 10 mg dose, the EF score, SEP2, and SEP3 in the LEVITRA group were 21 (baseline 13), 75%, and 64%, respectively, compared to 15 (baseline 14), 52%, and 32%, respectively, in the placebo group.
