Vardenafil's indications and contraindications are the same as with other PDE5 inhibitors; it is closely related in function to sildenafil citrate (Viagra) and tadalafil (Cialis). The difference between the vardenafil molecule and sildenafil citrate is a nitrogen atom's position and the change of sildenafil's piperazine ring methyl group to an ethyl group. Tadalafil is structurally different from both sildenafil and vardenafil. Vardenafil's relatively short effective time is comparable to but somewhat longer than sildenafil's.

Satisfaction Study II Trial purpose This trial is to provide additional important information on the impact of the treatment of the man its ED with vardenafil on partnership. This study is being run at up to 50 study centers in Europe and South Africa to evaluate the use of vardenafil in adult men with erectile dysfunction (often called impotence), and their female partner's sexual quality of life.
- Drug interactions include HIV protease inhibitors and antifungals.
- May interact with erythromycin and other antibiotics.
- Consult doctor before combining with other medications.
Many men experience occasional erectile problems during their lives.
| Patient Type | Starting Dose | Max Dose | Notes |
|---|---|---|---|
| Adults with ED | 10 mg, taken 1 hour before activity | 20 mg | Adjust based on efficacy and tolerability |
| Elderly patients | 5 mg or lower | 10 mg | Increased caution due to metabolism changes |
| Patients on CYP3A4 inhibitors | 5 mg | 10 mg | Reduce dose to prevent side effects |
However, when this becomes a continued problem, it can affect both the man and his female partner.
Trending on Pharmacy Times
Despite the structural differences between vardenafil and sildenafil, they both show similar ocular side effects due to their similar selectivity overlap with PDE6, an enzyme found in the eye. Beyond its indications for erectile dysfunction, vardenafil may be effective in the treatment of premature ejaculation, where it may significantly increase the time from penetration to ejaculation. The common, adverse drug reactions (side effects) are the same as with other PDE5 inhibitors. The frequent vardenafil-specific side-effect is nausea; the infrequent side effects are abdominal pain, back pain, photosensitivity, abnormal vision, eye pain, facial edema, hypotension, palpitation, tachycardia, arthralgia, myalgia, rash, itch, and priapism. One possibly serious, but rare, side effect with vardenafil is heart attack.
Role in Erectile Dysfunction Management
Also, super p force 160mg in rare cases, vardenafil use may cause priapism, a very painful emergency condition that can cause impotence if left untreated. In October 2007, the U.S. Food and Drug Administration (FDA) announced that a warning about possible deafness (sudden hearing loss) would be added to the drug labels of vardenafil, and other PDE5 inhibitors. Vardenafil should not be used by people taking nitrate medications, because combining them with vardenafil might provoke potentially life-threatening hypotension (low blood pressure). Further, vardenafil causes lengthening of the QT interval.
Storage and Handling Instructions
Therefore, it should not be taken by people taking other medications that affect the QT interval (such as amiodarone). Vardenafil was co-marketed by Bayer Pharmaceuticals, GlaxoSmithKline, and Schering-Plough under the brand name Levitra. As of 2005, the co-promotion rights of GSK on Levitra have been returned to Bayer in many markets outside the US. Thus, because of European Union trade rules, parallel imports might result in Vivanza sold next to Levitra in the EU. An orally disintegrating form, marketed as Staxyn and Levitra Soft, has been gaining approvals in countries such as the United States[11] and Canada. The causes of erectile dysfunction are varied and may be due to physiological or emotional reasons.
