Erectile dysfunction (ED) is a common problem. It can really affect a man’s life. Luckily, there are good treatments.
One group of treatments includes medicines called PDE5 inhibitors. You might know Viagra or Cialis. Zydena (drug name: Udenafil) is another medicine in this group.
It’s important to understand Zydena. This article explains what it is and how it works. We cover its uses, benefits, and risks simply and clearly. This info helps you talk with your doctor.
What is Zydena (Udenafil)?
Zydena is the brand name for the drug Udenafil. It belongs to the PDE5 inhibitor drug class. Doctors mainly use these drugs to treat Erectile Dysfunction (ED).
ED means having trouble getting or keeping an erection firm enough for sex.
Udenafil was first developed in South Korea. It works much like Viagra (sildenafil) or Cialis (tadalafil).
But there’s a key difference. Zydena (Udenafil) is not approved in the United States or Europe. The FDA and EMA have not approved it. This means you usually cannot get it from pharmacies in these areas. It’s mainly used in places like South Korea, Russia, and the Philippines.
How Does Zydena Work? The Simple Science
Let’s look at how erections normally happen. Sexual excitement releases a chemical called nitric oxide (NO) in the penis. NO makes another chemical called cGMP.
cGMP relaxes muscles in the penis arteries. This lets more blood flow in. More blood flow causes an erection.
An enzyme called PDE5 naturally breaks down cGMP. This makes the erection go away.
Zydena stops the PDE5 enzyme from working. This keeps more cGMP around when a man is sexually excited. More cGMP helps muscles stay relaxed and boosts blood flow. This makes getting and keeping an erection easier.
Important: Zydena doesn’t cause erections by itself. You need to be sexually stimulated first. The medicine only helps your body respond naturally to that stimulation.
Approved Uses and Possible Benefits of Zydena
The main approved use for Zydena (Udenafil) is treating erectile dysfunction. Studies in countries where it’s approved show it helps men with ED.
Zydena has a specific way it works in the body. Doctors look at how the body absorbs and uses a drug.
- How fast it works: Zydena usually starts working in about 30 to 60 minutes.
- How long it lasts: Its effects can last quite a while, often around 12 to 24 hours.
This timing falls between Viagra (shorter) and Cialis (much longer). Some men might prefer this middle-ground timing. It lasts long enough but maybe not too long for their needs.
Scientists have looked at Udenafil for other health issues too. But treating ED is its main, established use where it’s approved.
Know the Risks and Side Effects
All medicines can cause side effects. Zydena (Udenafil) is no exception. Side effects happen because the drug affects blood vessels, not just in the penis.
Common side effects are usually mild:
- Face feeling warm and red (flushing)
- Headache
- Stuffy nose
- Upset stomach or indigestion
These often lessen as your body gets used to the medicine.
Get medical help fast for less common but serious side effects:
- Sudden vision loss in one or both eyes
- Sudden hearing loss or ringing in ears
- Feeling dizzy or lightheaded
- Priapism: An erection that lasts longer than 4 hours. This is a medical emergency. Go to the hospital right away to prevent lasting damage.
Very Important Warnings:
The biggest risk with Zydena involves nitrate medicines. Doctors often prescribe nitrates for chest pain (angina). Examples are nitroglycerin or isosorbide. “Poppers” (amyl nitrite) also contain nitrates.
You must never take Zydena with any nitrate drug. Taking them together can cause a sudden, huge drop in blood pressure. This can be deadly. Doctors always check if you use nitrates before prescribing drugs like Zydena.
Also, be careful if you have:
- Serious heart problems (like a recent heart attack or stroke)
- Severe liver or kidney problems
- Very low blood pressure
- Certain rare eye diseases (like retinitis pigmentosa)
- Conditions that might cause priapism (like sickle cell anemia)
Tell your doctor your full health history. List all medicines and supplements you take. Other drugs can also interact with Zydena. These include alpha-blockers (for blood pressure or prostate) and certain other medicines.
Zydena Compared to Other ED Drugs
How does Zydena stack up against Viagra, Cialis, or Levitra? They all work similarly as PDE5 inhibitors. The main differences involve timing and food.
- Starts Working: Most start in 30-60 minutes. Zydena is in this range.
- How Long It Lasts: This varies a lot.
- Viagra & Levitra: About 4-6 hours.
- Zydena: About 12-24 hours.
- Cialis: Up to 36 hours (the “weekend pill”).
- Food: Eating a heavy, fatty meal can slow down Viagra and Levitra. Food affects Zydena and Cialis much less. This gives more flexibility.
- Side Effects: Common side effects are similar. But you might find one drug easier to take than another. For example, Cialis sometimes causes muscle aches because it lasts longer.
The “best” choice depends on you. Your health, lifestyle, and how you react matter most. Talk with your doctor to decide what’s right for you.
Using Zydena Safely and Well
If your doctor prescribes Zydena (where it’s legal):
- Dose: Take it by mouth as needed. Usually, this is 30-60 minutes before sex. Your doctor will find the right dose for you (often 100mg or 200mg).
- Timing: Don’t take it more than once a day.
- Prescription Needed: Always get Zydena with a doctor’s prescription. The doctor checks if it’s safe for you. They also look for health issues causing ED. Self-treating ED is risky.
- Watch Out for Fakes: Zydena isn’t sold everywhere. Be very careful buying it online. Many online sellers offer fake drugs. These can be useless or even harmful. Only use licensed pharmacies in places where Zydena is legally sold.
Where Things Stand Now
Zydena (Udenafil) is still a treatment option for ED in South Korea and some other nations. Doctors there continue to use it and learn from it.
It has not been approved for wider use in places like the US or Europe. Research on ED treatments is always ongoing. For now, Zydena’s use depends on where you live.
