In the pharmaceutical market in recent years there are a lot of drugs designed to treat erectile dysfunction. One such medicine is Zidena. Customer reviews indicate its rather high efficiency with a relatively recent appearance.
To date, there has been a general increase in life expectancy. This is what determines the need for tools such as Zidena. Reviews of men suggest that with age they have a large number of metabolic diseases, including erectile dysfunction.
Application
A drug is bought for the treatment of impaired erection, which is characterized by its complete absence or the inability of a man to maintain an excited state of the penis for a sufficient time for a satisfactory sexual intercourse.
pharmachologic effect
The drug "Zidena" reviews of pharmacists characterize as a reversible selective inhibitor of cGMP-specific phosphodiesterase type 5. Its main substance is Udenafil, which has no direct relaxing effect on a tricky isolated body, but with sexual stimulation it increases the relaxing effect of nitric oxide. As a result of this, the smooth muscles of the arteries relax, and blood flows to the tissues of the penis, which provokes an erection.
Men who used the Zidena pharmaceutical product left good reviews, noting that the effect of the drug is felt already after half an hour after taking it and continues throughout the day if there is sexual arousal. In the absence of sexual stimulation, this tool does not give the desired result.
In the course of numerous studies of udenafil in men, no significant clinical effect was found on the concentration and amount of sperm.
Contraindications
The drug "Zidena", like any other medicine, can not be used by everyone. Therefore, before taking it, you should consult a doctor who will tell you about all contraindications. So, for example, you can not take this medication simultaneously with drugs that contain nitrates or other nitric oxide donors. People with retinal diseases, high blood pressure, severe kidney and liver diseases should be careful about the drug. It is not recommended to take this medication for those who have undergone coronary artery bypass grafting, myocardial infarction, or stroke within six months before.
By increasing sexual activity in men, Ziden tablets can indirectly affect the occurrence of various complications in patients with cardiovascular diseases, anatomical changes in the shape of the penis or when an implant is located in it.
Of course, you should not take this drug if its components cause the man to be hypersensitive or not tolerated by the body.
