Both Udenafil and Sildenafil belong to the class of PDE5 inhibitors. The preparations are aimed at erectile dysfunction treatment and have the same mechanism of action. Getting into the blood flow both Udenafil and Sildenafil promote the release of nitric oxide, which takes part in the process of relaxing the flat muscles of the cavernous bodies of the male sex organ. If a man is sexually stimulated, the flow of blood to the penile area increases and an erection appears.
Due to the effect induced by these drugs almost 80% of men using them are able to achieve a firm and durable erection.
Though the remedies act the same, the duration and the onset of their action differ. Udenafil starts working in approximately an hour after the intake and may last up to 11 – 13 hours. In some cases, the effect of the drug may be felt even in 24 hours after the intake. Whereas Sildenafil comes into effect within 30-60 minutes but its effect lasts for only 4 – 6 hours.
So, Udenafil or Sildenafil – what to choose? Men, who need quick results should better choose Sildenafil (brand name Viagra) and those, who like to be spontaneous are recommended to use Udenafil (brand name Zydena) as it may be taken on a daily basis.
Zydena compared to generic Viagra is not approved by FDA, hence, it’s much more difficult to get it.
How to take these drugs
Sildenafil the same as Udenafil may be taken regardless of meals. However, fatty food may affect the absorption of Sildenafil and as a result, delay the onset of its action. Both drugs should be administered with a full glass of water.
Unlike Sildenafil, Udenafil may be taken either when it is needed or on the regular basis. It makes possible to get an erection whenever you are going to have sex. It is a huge benefit for those men who like to be spontaneous and always ready for intimacy.
Nevertheless, you shouldn’t take more than one pill of Sildenafil or Udenafil within 24 hours. Exceeding the dose may provoke some unwanted reactions.
Both medicines are PDE5 inhibitors. That’s why they share the same precautions to the intake. You have to consult with a medical specialist to learn about all the possible contraindications. Here are some of the most common:
- Allergy to an active component of the remedy;
- Heart disease;
- Uncontrolled hypertension or very low blood pressure;
- Severe eye ailments;
- Kidney or liver problems;
- Stroke, a heart attack or heart surgery within the last 6 months.
In addition, patients administering nitrate drugs for heart disease shouldn’t take any PDE5 inhibitors as it may result in a life-threatening decrease of the blood pressure.
Males younger than 18 are not advised to take the drug. Besides, the therapy with Sildenafil or Udenafil in patients over 65 should be conducted under the doctor’s supervision.
To avoid dangerous interactions, inform your healthcare provider about all the drugs, vitamins, minerals, and herbal substances you take.
To sum up, every patient may try both medications and then decide which of the two suits his needs and desires best of all.
