ED medications differ by the active components and methods by which they should be taken. They are oral drugs,  injections into the penis, drugs inserted into the urethra.

Oral medications such as Viagra, Levitra or Cialis and other their alternatives are widely available on the market and very popular among doctors and patients.

All brand drugs such as Levitra are approved by FDA and were tested for safety and effectiveness.

Levitra, Viagra and Cialis belong to a drug class – phosphodiesterase type 5 (PDE) 5 inhibitors. These drugs for oral intake work by enhancing the effects of nitric oxide and allow increased blood inflow into the penis. Oral drugs improve the response to sexual stimulation but do not make an erection automatically. Sexual stimulation is necessary.

The recommended dose for Levitra is 10 mg, but your doctor may alter this dose to 20 mg if 10 mg is insufficient. A lower dose of 5 or even 2.5 mg is indicated for men who take other medicines or have conditions that may decrease the body’s ability to use the drug. PDE inhibitors should be used only once a day.

Injections make the erections automatically. Usually injections help men achieve stronger erections. The drugs such as papaverine hydrochloride, phentolamine, and alprostadil are injected directly into the penis, causing it to become filled with blood.  Still these injections sometimes cause priapism – prolonged and painful erections. For people with certain diseases injections are not recommended.

The other ED medication therapy is a system for inserting the drug alprostadil into the urethra. An erection occurs within 8 to 10 minutes after the drug is inserted and lasts usually 30 to 60 minutes enough to have sexual intercourse.

ED medications market is constantly developing; new methods are created and used to improve men’s ability to have an erection. Ask your doctor about the latest advances and find the right option for you.
