An Overview of Erectile Dysfunction Tablets
Therefore, in men over 65 years of age with liver disease, or who are also taking medication(s) that can slow the breakdown of vardenafil, the doctor will initiate vardenafil at low doses to avoid its accumulation.
Other Conditions Treated with PDE5 Inhibitors
Patients with blood cell diseases such as sickle cell anemia, leukemia, and multiple myeloma have higher than normal risks of developing priapism. Untreated priapism can cause injury to the penis and lead to permanent impotence. Therefore, if your erection lasts four hours, you should seek emergency medical care. Rare side effects of all PDE5 inhibitors include a sudden loss of vision in one or both eyes (nonarteritic anterior ischemic optic neuropathy [NAION]) and sudden loss of hearing. Patients have reported these rare side effects with all of the PDE5 inhibitors.
Recreational use
Seek immediate medical care if you develop a loss of vision or hearing. Doctors have not tested the PDE5 inhibitors in patients with retinitis pigmentosa, an eye condition that affects the retina and can cause blindness, so caution is recommended if you have this health condition. Sildenafil (Viagra) was the first oral phosphodiesterase type 5 (PDE5) inhibitor approved by the FDA in the United States for the treatment of erectile dysfunction (it is not approved for women). Sildenafil inhibits PDE5, which is an enzyme that destroys cGMP. By inhibiting the destruction of cGMP by PDE5, sildenafil allows cGMP to accumulate.
A Safer Solution
The cGMP in turn prolongs the relaxation of the smooth muscle of the corpora cavernosa. Relaxation of the corpora cavernosa smooth muscle allows blood to flow into the penis resulting in increased engorgement of the penis. In short, sildenafil increases blood flow into the penis and decreases blood flow out of the penis. Sildenafil treats erectile dysfunction of either physical or psychological causes. It is effective in treating erectile dysfunction in men with coronary artery disease, diabetes mellitus, hypertension, depression, coronary artery bypass grafting (CABG), and men who are taking antidepressants and several classes of antihypertensives. Men taking erythromycin or ketoconazole should not take more than 5 mg of vardenafil in 24 hours Men taking high doses of ketoconazole (Nizoral) should not take more than 2.5 mg of vardenafil in 24 hours Men with moderately severe liver disease also should not take more than a 5 mg dose of vardenafil within 24 hours Men taking the protease inhibitor (for the treatment of HIV/AIDS) indinavir (Crixivan) should not take more than 2.5 mg of vardenafil in 24 hours Men taking another protease inhibitor ritonavir (Norvir), erythromycin, or ketoconazole, should not take more than 2.5 mg of vardenafil every 72 hours Tadalafil (Cialis) is the third oral medicine approved by the U.S.

Like sildenafil (Viagra) and vardenafil (Levitra), tadalafil inhibits PDE5 (as described earlier). Unlike the other PDE 5 inhibitors, patients should take tadalafil once daily which is approved for the treatment of BPH (benign enlargement of the prostate).
- Age factors: Prevalence increases with age, but ED is not an inevitable part of aging.
- Young men: Can experience ED due to psychological factors or lifestyle choices.
- Middle-aged: Often a mix of physical and psychological causes.

Patients may take tadalafil as needed as with sildenafil, vardenafil, and avanafil, or once a day. It is the only ED oral medication that patients can take daily.
other ED treatments
In randomized placebo-controlled trials, an estimated 60% of men with diabetes, and 80% of men without diabetes experienced improved erections with sildenafil. Sildenafil is available as oral tablets at doses of 25 mg, 50 mg, and 100 mg. Patients should take sildenafil approximately one hour before sexual activity. In some men, the onset of action of the drug may be as early as 11-20 minutes. Men should take sildenafil on an empty stomach for best results since absorption and effectiveness of sildenafil can be diminished if it is taken shortly after a meal, particularly a meal that is high in fat.
If you develop priapism
Sildenafil and the other PDE5 inhibitors don't cause an immediate erection. Sexual stimulation is necessary for these medications to work. In prescribing sildenafil, a doctor considers the age, general health status, and other medication(s) the patient is taking. The usual starting dose for most men is 50 mg, however, the doctor may increase or decrease the dose depending on side effects and effectiveness. The maximum recommended dose is 100 mg every 24 hours.

However, many men will need 100 mg of sildenafil for optimal effectiveness, and some doctors are recommending 100 mg as the starting dose. Aging, liver and kidney problems and concurrent use of certain medications (such as erythromycin [an antibiotic] and vigora 200 mg protease inhibitors for HIV) slow the metabolism (breakdown) of sildenafil. Slowed breakdown allows sildenafil to accumulate in the body and potentially may increase the risk of side effects. Therefore, in men over 65 years of age, men with significant kidney and liver disease, and men who also are taking medications called protease inhibitors, the doctor will initiate sildenafil at a lower dose (25 mg) to avoid the accumulation of sildenafil in the body. A protease inhibitor ritonavir (Norvir) is especially potent in increasing the accumulation of sildenafil, thus men who are taking Norvir should not take sildenafil doses higher than 25 mg and at a frequency of no greater than once in 48 hours. The recommended starting dose of tadalafil for use as needed for most patients is 10 mg taken orally approximately one hour before sexual activity.
| Drug Name | Active Ingredient | Typical Dose | Onset Time | Duration of Action | Common Uses | Side Effects |
|---|---|---|---|---|---|---|
| Viagra | Sildenafil | 50 mg | 30-60 min | 4-6 hours | Erectile dysfunction | Headache, flushing |
| Cialis | Tadalafil | 20 mg | 30 min | Up to 36 hours | ED, BPH | Muscle pain, nausea |
| Levitra | Vardenafil | 10 mg | 25-60 min | 4-5 hours | ED | Nasal congestion |
| Stendra (Avanafil) | Avanafil | 100 mg | 15 min | Up to 6 hours | Rapid onset ED | Dizziness |
A doctor may adjust the dose higher to 20 mg or lower to 5 mg depending on efficacy and side effects.

Addressing underlying health conditions and minimizing stress can also reduce symptoms of ED
The QT interval is the time it takes for the heart's muscle to recover after it has contracted. An vardenafil oral electrocardiogram (EKG) measures the QT interval. Some people have longer than normal QT intervals, and they may develop potentially life-threatening abnormal heart rhythms, especially when given certain medications. Men with a family history of long QT syndrome should not take vardenafil, as it is possible to inherit long QT syndrome. Furthermore, vardenafil is not recommended for men who are taking medications that can affect the QT interval such as quinidine (Quinaglute, Quinidex), procainamide (Pronestyl, Procan-SR, Procanbid), amiodarone (Cordarone), and sotalol (Betapace).
Best for daily use: Cialis
There is insufficient information on the safety of vardenafil in men with the following health disorders: Unstable angina (chest pain due to coronary artery disease that occurs at rest or with minimal physical exertion) Low blood pressure (resting systolic blood pressure less than 90 mm Hg) Uncontrolled high blood pressure (greater than 170/110 mm Hg) Recent stroke or heart attack (within six months) Uncontrolled, potentially life-threatening abnormal heart rhythms Severe heart failure or disease of the heart's valves, for example, aortic stenosis (hardening of the main artery in the body) Retinitis pigmentosa (a condition that affects the retina of the eye and can cause blindness) Therefore, men with these health conditions should not use vardenafil without having these conditions evaluated and stabilized first. For example, men with uncontrolled high blood pressure should have their blood pressure controlled; and men with potentially life-threatening abnormal heart rhythms should have these rhythms controlled. When there is angina or heart failure, the doctor may need to determine whether the heart has enough reserve to carry out the work necessary for sexual activity by performing cardiac treadmill stress testing. Metabolism (breakdown) of vardenafil can be slowed by aging, liver disease, and concurrent use of certain medications (such as erythromycin [an antibiotic], ketoconazole [Nizoral, a medication for fungal/yeast infections], and protease inhibitors [medications used to treat AIDS]). Slowed breakdown allows vardenafil to accumulate in the body and potentially increases the risk for side effects. Some patients can take tadalafil less frequently since the improvement in erectile function may last 36 hours.
- Ed tablets require sexual stimulation to initiate an erection.
- They do not increase libido; they only facilitate physical response.
- Over-the-counter Ed supplements lack scientific backing and may be unsafe.
- Regular exercise can enhance the effectiveness of Ed tablets.
- Ed tablets are often combined with lifestyle advice for better results.
- They are a non-invasive alternative to surgical treatments.
- Ed tablets have millions of satisfied users worldwide.
- Always follow medical advice for dosage and timing of administration.
Patients may take tadalafil with or without food. Tadalafil is currently the only PDE5 inhibitor that is FDA-approved for daily use for erectile dysfunction and is available in 2.5 mg or 5 mg dosages for daily use.

Other medications that may affect the level of sildenafil include erythromycin and ketoconazole. Sildenafil (Viagra) may affect another phosphodiesterase enzyme in the eye causing transient abnormal vision (seeing a bluish hue or brightness). Vardenafil (Levitra) was the second oral medicine approved by the U.S. FDA for the treatment of erectile dysfunction. Like sildenafil (Viagra), vardenafil (Levitra) inhibits PDE5, which destroys cGMP (as discussed earlier).
Maintain a healthy weight
It is the only PDE 5 inhibitor that has a generic form available. Vardenafil is effective in men of all ages, of different nationalities, and in men with such medical conditions as diabetes mellitus and erectile dysfunction after prostate surgery. The recommended starting dose of vardenafil is 10 mg taken orally approximately one hour before sexual activity. A doctor may adjust the dose higher or lower depending on efficacy and side effects. The maximum recommended dose is 20 mg, and the maximum recommended dosing frequency is no more than once per day.
Be physically active
Patients can take vardenafil with or without food. As with sildenafil, for vardenafil to be effective, sexual stimulation must occur. Vardenafil shares the same side effects as sildenafil but is not associated with the abnormal vision that may occur with sildenafil. The same concerns regarding the use of sildenafil with nitrates and alpha-blockers apply to vardenafil. Men with a rare heart condition known as long QT syndrome should not take vardenafil since this may lead to abnormal heart rhythms.
