Zudena 100 is a reversible selective cyclic guanosine monophosphate inhibitor of type 5 specific phosphodiesterase. Udenafil has no direct relaxing effect on the isolated cavernous body, but during sexual stimulation, the drug potentiates the relaxing effect of nitric oxide by inhibiting inhibition of type 5 phosphodiesterase, which is responsible for the breakdown of cyclic guanosine monophosphate in the cavernous body. These effects lead to relaxation of the smooth muscles of the arteries, blood flow to the tissues of the penis and erection.
Zudena 100 is taken orally, regardless of the meal. The drug is taken once a day, half an hour before the intended sexual activity, at the recommended dose of 100 mg. Given the individual tolerance and effectiveness of the dose of Udenafil can be increased to 200 mg.
Sexual activity is dangerous for people with pathology of the cardiovascular system, therefore, treatment of erectile dysfunction, including with the use of Zudena 100, should not be carried out for men with heart disease, for which sexual activity is not recommended.
In case of an overdose of Udenafil, side effects may occur. Symptomatic treatment is required.
Zudena 100 is not intended for women and children under 18.
