A Recap On How To Get An Erection
It all starts in the brain. There are six systems involve in getting an erection: the brain, emotion, hormones, nerves, blood vessels, and muscles. Your brain and muscles have to relax. You have to relax.
Your brain will relay messages to your emotions. How are you feeling? Are you feeling relaxed, do you feel anxious, or are you feeling depressed? Do you have feeling of a rush and distracted?
Next are the hormones that get released in your brain. These hormones will then stimulate the nerves in the back of your head and to your heart. Then your heart pumps up more blood to your blood vessels. Lastly, the blood will go to your penis muscles.
Thus in order for you to get an erection, your brain has to relax, your emotions have to be in the right spot, and your penis muscle has to relax.
How ED Medications Works
ED medications goes to your penis muscle and inhibits the breakdown of a chemical called Cyclic GMP. That way you have more of that in the penis muscle, and that relaxes the smooth muscle of the penis. That's how these medications helps with erection.
Viagra, Cialis, or Levitra works on the smooth muscle of the penis. However, as you know, ED is really a blood flow problem. It starts in the endothelium. Endothelium is the lining of the blood vessels that secretes nitric oxide. The endothelium is impaired by either high blood pressure, diabetes, high cholesterol, obesity, stress, not getting enough sleep, smoking, drinking too much alcohol, or taking certain drugs.
When you take medications for ED, it's going directly to your penis smooth muscle. It doesn't do anything to the blood vessels at all. As you know, the blood flow problem is really what's behind ED. But what these medications does is it just goes to the penis smooth muscle. It does not address poor blood flow problems due to endothelial dysfunction.
Medications More Likely To Cause ED
- Antidepressants such as Zoloft, Paxil, Celexa, Prozac, and Elavil.
- Antiulcer medications particularly Tagamet, Pepcid, and Zantac.
- Beta blockers such as propranolol, timolol, and penbutolol.
- Diuretics like Diuril, Aldactone, and Thalitone.
- Tranquilizers such as or Valium, Mellaril, or Librium.

Medications Less Likely To Cause ED

- Calcium-channel blockers which is Cardizem, Procardia, and verapamil.

Side Effects of ED Medications
The most common side effects of ED medications are headaches, facial flushing, and indigestion. Vision problems, including changes in color vision, blurry vision, sensitivity to light, and hearing changes are other side effects these medications as well. ED medications can also cause low blood pressure which can lead to dizziness, lightheadedness, or fainting. This is especially true if you take these drugs with other medications that lower blood pressure or consume alcohol.
In rare cases, ED medications can also cause priapism, a prolonged and painful erection that lasts more than four hours. If you experience priapism, seek medical attention immediately, as it can lead to permanent damage to the penis.
It's essential to note that ED medications is not suitable for everyone, especially those with certain medical conditions or who take specific medications.

The effectiveness of these medications can also depend on the underlying cause of ED. For example, if ED is caused by a physical condition, such as diabetes or cardiovascular disease, medications may be less effective than if ED is caused by a psychological condition, such as anxiety or depression.
