If the sildenafil response is not reliably improving erection, the physician should first check if the patient is taking the pill correctly. The physician should also check the patient’s testosterone level. One investigator in Italy gave testosterone to patients with low testosterone who did not respond to sildenafil (Viagra).

When daily testosterone was given, subsequent sildenafil (Viagra) use resulted in IIEF (the International Index of Erectile Function questionnaire used to determine erectile function) scores improving significantly. Other risk factors for erectile dysfunction include neurologic problems (multiple sclerosis, stroke), depression and medications for treating diabetes, hypertension, heart disease and depression. There are many oral therapies for erectile dysfunction, but the only approved medication in the US is the PDE 5 enzyme inhibitor sildenafil (Viagra).

Unapproved therapies, some of which are available in the US and some elsewhere, some of which have data to prove efficacy and some not, include tadalafil (Cialis), vardenafil (Levitra), yohimbine, phentolamine, trazodone, apomorphine and neutraceuticals. PDE5 inhibitors act to relax penile erectile tissues with sexual stimulation thus enhancing your ability to get an erection. Sildenafil (Viagra) is effective for all sorts of erectile dysfunction in 69% of people. Why is there a need for another pill? In some cases the erection is not hard enough, sometimes sildenafil (Viagra) just doesn’t work. Structurally vardenafil (Levitra) is similar to sildenafil, while tadalafil (Cialis) is very different.
| Tip | Explanation | Best Practice |
|---|---|---|
| Consult a healthcare professional | To determine appropriateness and safe dosage | Essential before starting treatment |
| Start with low dose | To minimize side effects and assess response | Usually 25-50 mg |
| Monitor and report side effects | To optimize treatment and safety | Follow-up appointments |
| Combine with behavioral therapy | Enhances overall outcomes | Address psychological factors |
Vardenafil (Levitra) is almost 10 times more biochemically potent than sildenafil, therefore a lower dose is needed to facilitate the penile erection, potentially resulting in less side effects.
- Sildenafil's role in PE is still under research.
- Off-label use requires informed consent.
- Behavioral techniques are first-line in many cases.
- The impact of psychological health on PE should not be ignored.
- Educating patients on realistic expectations is important.
- Sometimes, medication just masks underlying issues.
- Regular sexual activity can decrease PE severity.
- Consulting a urologist is recommended for persistent PE.
- Combining medication with therapy often improves outcomes.
- Delaying ejaculation involves both physical and mental strategies.
- Support and understanding enhance treatment adherence.
Selectivity is the ability of the drug to attach to the specific enzyme PDE 5 found in penile tissues. Vardenafil (Levitra) is more selective than sildenafil and tadalafil (Cialis) to PDE5, which again means a lower dose is needed with potentially less side effects.

Since a straddle injury or use of a narrow saddle can obstruct and impair arteries to the penis, bicycle riding is also considered a risk factor for erectile dysfunction. Little attention has been paid to endocrine factors. Testosterone modulates desire, arousal and orgasmic function. Concerning the orgasmic response, testosterone modulates the integrity of genital sensory receptors. Concerning the arousal response, decreased testosterone blood levels can influence the efficacy of sildenafil (Viagra). Tadalafil is very specific for PDE5 and is also very specific for the enzyme PDE11.

FAQs on ED Medications and Premature Ejaculation
What Is the Role of Ejaculation Latency in the Diagnosis of Premature Ejaculation and Does the Ejaculation Latency Threshold Matter? Conservative Non-surgical Options for Erectile Dysfunction Current Urology Reports (2023) The role of tyrosine hydroxylase within dapoxetine-assisted therapy against premature ejaculation Molecular Biology Reports (2023) Current and emerging treatment options for premature ejaculation Nature Reviews Urology (2022) Redefining a sexual medicine paradigm: subclinical premature ejaculation as a new taxonomic entity Nature Reviews Urology (2021) The most common sexual dysfunctions in men include lack of interest, premature ejaculation and erectile dysfunction. The latter affects 52% of men between the ages of 40 and 70, including mild, moderate and complete forms of ED. Organic or physical causes for sexual dysfunction in men include vascular, hormonal and neurologic factors. Concerning vascular causes, the risk factors for atherosclerosis (including smoking, high blood pressure, diabetes (diabetics do not respond well to pills like sildenafil (Viagra)) and high cholesterol are ALSO risk factors for erectile dysfunction. Unfortunately, we don’t know much about PDE11, which is found in the heart, in the pituitary gland in the brain and in the testicles. Pharmacokinetics, half-life, is how long the medication stay s in the blood. This means that vardenafil (Levitra) should act longer than sildenafil (Viagra) but the clinical significance is not known. Tadalafil (Cialis) has the longest half-life and allows you to take the medication and not relate the sexual activity to the immediate use of the medication.
