What is Levitra?
Levitra (Vardenafil) is a phosphodiesterase inhibitor (PDE-5 inhibitor). It works by relaxing the muscles and increasing the blood flow into the penis during sexual arousal. This helps to achieve and maintain a normal erection needed for a proper sexual intercourse.
This drug is used to treat erectile dysfunction (impotence).
The drug quickly enters the bloodstream and spreads throughout the body, which explains the very rapid response after the administration.
The first signs of Levitra action can be seen in 25 minutes (depending on the individual characteristics of each person, the period could be delayed by 5-15 minutes or, on the contrary, appear much sooner).
The total duration of the drug action per dose is about 4 – 5 hours. As noted by experienced doctors, the maximum effect of Levitra functioning in the blood is observed one hour after administration – this interval is considered to have a peak effect.
Based on the researchers, a month of constant drug use, even against the
background of complete impotence, may 100% restore male power. Continue reading about

Generic Levitra
Generic Levitra is completely similar to the original drug, which is used to maintain and restore the male sexual function. The active substance of this drug is Vardenafil.
Being affordable ED medication, the generic version has the same quality and functions as the original drug. If you consider a purchase, reviews of other men and the actual practice of the treatment, the drug will be able to help you decide on the right solution.
Vardenafil mechanism of action is almost identical to the famous Viagra, but Vardenafil has higher efficiency and fewer restrictions for use.
In the absence of contraindications and the need for additional stimulation of
the erectile function, it will be definitely a good solution to buy Levitra
(Vardenafil) online.
Dosage and Instructions for Use
Levitra dosages available at My Canadian Pharmacy are 10 mg, 20 mg, 40 mg, 60 mg, 100 mg.
Taken orally, regardless of meals.
It’s recommended to start with a 10 mg dosage (approximately 25-60 minutes before the planned sexual intercourse). The maximum recommended dosage is 20 mg 1 time per day.
In order to ensure an adequate response to treatment, man needs a sexual stimulation. The drug proves to be effective even when taken 4-5 hours before sexual intercourse. Elderly patients (over the age of 65) do not need a dose adjustment.
Overdose
Symptoms of an overdose: Participants of the research took Vardenafil at the dose of 80 mg per day and had no serious adverse reactions. However, administration of Vardenafil 40 mg 2 times a day caused apparent pain without signs of toxic action on the muscular and nervous systems.
Treatment of an overdose: In case of overdose, man needs the standard supportive
therapy. As Vardenafil is highly linked to plasma proteins and only a small
amount of the drug is excreted by the kidneys, the dialysis efficiency is
unlikely. Read more details

Levitra vs Viagra
Viagra and Levitra are the most popular and effective ED drugs. They both belong to the same class of drugs called phosphodiesterase inhibitors (PDE-5 inhibitors) that block the enzyme phosphodiesterase type 5.
Viagra was the first drug to enter the pharmaceutical market and was approved as an effective cure for erectile dysfunction.
The second ED drug entered the market in August 2003.
The efficiency of both formulations is about 80-90%. The greatest advantage of these drugs is that a man can feel normal during a routine pastime, an erection occurs only at the time of sexual intimacy (sexual stimulation). No stimulation – no erection. The drug is taken orally before sexual stimulation. Their primary goal is to increase the blood flow to the penis.
Side effects of both drugs are possible but individual. The most common are
redness on the face (neck), nasal congestion, dizziness. Levitra side effects
occur in 3% of cases, Viagra side effects – in 9%. See Levitra vs
Viagra in more detail…
