There are several different types of erectile dysfunction (ED) medications available, but not all of them are equally effective. One of the most common types of ED medication is vardenafil, which must be taken on an empty stomach, and it is also one of the most affordable options. It works by inhibiting the PDE5 enzyme, which breaks down cGMP. By blocking the PDE5 enzyme, sildenafil is able to work faster and last longer. It is also more expensive than Viagra (sildenafil), but it is a good option if sildenafil has not been effective. However, vardenafil comes with the same side effects as sildenafil.
Prices of ED medications can vary greatly, and you should consult your physician before starting a new medication. Generic medications are generally less expensive than brand-name drugs, but be aware that they may have side effects and should only be used under medical supervision.
Another side effect of ED medications is muscle pain. Tadalafil, for example, can cause muscle pain in some men. Vardenafil, on the other hand, only requires a lower dosage to work effectively. In addition, vardenafil may cause nasal congestion, which may be uncomfortable.
