Zydena (Udenafil) Undergoes U.S. Trials
Udenafil is a new oral treatment for erectile dysfunction developed by the Korean Dong-A PharmTech Co. Ltd. This new medication has entered phase III trials in the United States.
Udenafil is a long-lasting PDE-5 inhibitor, and so it works in the same mechanism as Viagra, i.e. it relaxes blood vessels and allows more blood to flow to the genitals, which improves the man’s ability to achieve and maintain a firm erection during sexual arousal.
This drug is already approved and marketed under the brand name Zydena in some countries, including Korea and Russia. Dong-A is crossing fingers that in a couple of years they will be granted marketing authorization for Udenafil in the US and EU.
If it gets approved by the FDA, Zydena (Udenafil) will become the fourth prescription treatment option for ED patients that will compete with Viagra (sildenafil citrate), Cialis (tadalafil), and Levitra (vardenafil). More competition is always in favor of consumers who get more options, from which they can choose what is best for them in terms of results, safety, and price (after consulting a doctor, of course).
Using Vacuum Pumps to Treat Erectile Dysfunction
There are various treatments for erectile dysfunction (ED). Prescription medications, like Viagra (sildenafil citrate), are clinically proven, dependable, and work pretty fast. Another option for ED patients is vacuum pumps, which we will explain in this post.
Vacuum pumps (aka penis pumps) are simple devices that are used, among other things, to help men with erectile dysfunction get and maintain an erection by creating a vacuum around the penis.
The device mainly consists of a hollow cylindrical tube (usually made of plastic), inside of which the user can insert his penis. The device also includes a vacuum pumping device that absorbs the air out of the tube creating vacuum around the penis. This vacuum forces the penis to stretch and more blood flows into the penis causing a full and large erection. The user can then place a special rubber ring at the base of the penis to keep the blood trapped into the penis and maintain the erection for as long as needed and until the ring is removed.
Some men with erectile dysfunction may find this technique helpful and reliable, while others would never even consider it. The following are some of the advantages and disadvantages of vacuum pumps. Read more
