(May 2010) Medications for erectile dysfunction include: oral phosphodiesterase type 5 (PDE5) inhibitors (sildenafil (Viagra), vardenafil (Levitra), and tadalafil (Cialis) Sildenafil can cause hypotension (abnormally low blood pressure that can lead to fainting and even shock) when given to patients who are taking nitrates (for heart disease). Therefore, patients taking nitrates daily should not take sildenafil. Nitrates are used most commonly to relieve angina (chest pain due to insufficient blood supply to the heart muscle because of narrowing of the coronary arteries); these include nitroglycerine tablets, patches, ointments, sprays, and pastes, as well as isosorbide dinitrate, and isosorbide mononitrate. Other nitrates such as amyl nitrate and butyl nitrate also are found in some recreational drugs called "poppers." buy generic cialis online usa buy cialis online

Erectile Dysfunction At A Glance: New research is ongoing in the field of erectile dysfunction to find more improved and effective therapies. What precautions should be taken when using vardenafil (Levitra)? Metabolism (breakdown) of vardenafil can be slowed by aging, liver disease, and concurrent use of certain medications (such as erythromycin, ketoconazole [Nizoral], and protease inhibitors). Slowed breakdown allows vardenafil to accumulate in the body and potentially increase the risk for side effects. Therefore, in men over 65 years of age, with liver dysfunction, or who are also taking medication(s) that can slow the breakdown of vardenafil, the doctor will initiate vardenafil at low doses to avoid its accumulation. Cavernosography measurement of the vascular pressure in the corpus cavernosum. Saline is infused under pressure into the corpus cavernosum with a butterfly needle, and the flow rate needed to maintain an erection indicates the degree of venous leakage. The leaking veins responsible may be visualised by infusing a mixture of saline and x ray contrast medium and performing a cavernosogram.; Digital Subtraction Angiography: In DSA, the images are acquired digitally. A penile erection is the hydraulic effect of blood entering and being retained in sponge-like bodies within the penis. The process is often initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the penis. Erectile dysfunction is indicated when an erection is difficult to produce. There are various circulatory causes, including alteration of the voltage-gated potassium channel, as in arsenic poisoning from drinking water. The most important organic causes are cardiovascular disease and diabetes, neurological problems (for example, trauma from prostatectomy surgery), hormonal insufficiencies (hypogonadism) and drug side effects. Erectile dysfunction is characterized by the regular or repeated inability to obtain or maintain an erection. It is analyzed in several ways: Obtaining full erections at some times, such as when asleep (when the mind and psychological issues, if any, are less present), tends to suggest that the physical structures are functionally working. cheap cialis online pharmacy buy cialis online

To identify your pelvic floor muscles: firstly, contract the muscles that you would use to stop passing wind from your anus; secondly contract the muscles that you would use to stop the flow of urine. These are the muscles that can be trained and strengthened. Ideally, discuss this option with your GP. If this option is considered appropriate to try, then ideally you should see a physiotherapist for advice on exactly how to do the correct exercises. Also, see the references at the end of this article. brand cialis online What Are Ejaculation Disorders?
