The mechanism of action of Viagra, Levitra, Staxin, and Cialis is the same, but each of these prescription drugs for the treatment of erectile dysfunction differs in its chemical composition. Due to the unique features of the composition of these drugs for the treatment of erectile dysfunction, each of them affects patients differently. Aspects such as potential side effects, time to achieve results, and duration of action of the erectile dysfunction drug vary from brand to brand. A doctor with experience in the treatment of impotence will know how these erectile dysfunction medications work and will be able to determine which medication is the best option for a particular patient, taking into account the specific health problems of this patient and possible drug interactions.
Drugs for the treatment of erectile dysfunction Viagra and Levitra can be taken by the patient once a day, about 30-60 minutes before sexual intercourse. These two prescription medications for erectile dysfunction do not have to be taken with meals, and the effect lasts about five hours. Levitra, one of the brands of vardenafil, is also available in a tongue-dissolving form. This medication for erectile dysfunction is sold to patients under the brand name Staxyn.
One form of Cialis is taken slightly differently than the other most commonly prescribed drugs for the treatment of erectile dysfunction. In a small daily dose, Cialis is taken regardless of food intake every day. Since this is a permanent drug, Cialis in small doses is effective at any time when the patient desires regular sexual activity. It does not need to be taken before such activity.
The second form of the drug Cialis for the treatment of erectile dysfunction can be taken only as needed before sexual activity. This form is valid for up to 36 hours and gives results when taken about 30 minutes before sexual intercourse. The 36-hour version of the drug Cialis for the treatment of erectile dysfunction can be taken regardless of the meal, no more than once a day.
Stendra is a new development in the world of drugs for the treatment of erectile dysfunction. Approved in the US by the FDA, it is similar to Viagra, Cialis, and Levitra. Since this is a novelty on the market, a qualified doctor with experience prescribing drugs for the treatment of erectile dysfunction will know whether Stendra is the best option for his or her patients.
Concerns about the use of drugs to treat erectile dysfunction
Men with certain health problems or taking other medications may not be good candidates for erectile dysfunction medications. If the patient has any of the following health problems, a qualified doctor will be able to determine whether erectile dysfunction medications are the right choice:
- Uncontrolled blood pressure (high or low)
- Recent history of stroke
- Heart problems, poor blood flow, angina, arrhythmia, or a recent heart attack
- Liver disease
- Kidney disease requiring dialysis
- Special eye problems
Patients taking nitrates for heart problems should not take medications to treat erectile dysfunction. This is due to the fact that nitrate drugs act similarly to drugs for the treatment of erectile dysfunction with dilation of blood vessels. Together, erectile dysfunction drugs and nitrates can lead to excessively low blood pressure and even loss of consciousness. Some medications that contain nitrates and do not allow the patient to take medications for erectile dysfunction include:
- nitroglycerin
- Amyl Nitrite or other prohibited drugs
- isosorbide
It is very important that a patient suffering from erectile dysfunction be very honest with their doctor about any prescription medications they take, as many of them may interact negatively. Recipes that are known to interact negatively with drugs for the treatment of erectile dysfunction Viagra, Cialis, and Levitra:
- Antibiotics
- Anticonvulsants
- Alpha-blockers
- Blood Thinners
- Cardiac drugs for arrhythmia
Side effects of drugs for the treatment of erectile dysfunction in most men are rare. If side effects occur when taking medications to treat erectile dysfunction, they may include:
- upset stomach
- Headache
- Nasal congestion or runny nose
- Muscle pain
- Temporary vision changes
- Fainting or dizziness
Very few patients with erectile dysfunction experience more serious side effects. If they do occur, they may include:
- Loss of vision or hearing
- Painful erection that does not go away by itself for more than four hours.
As with any prescription or over-the-counter medication, erectile dysfunction medications can be purchased online. Patients taking erectile dysfunction medications should be careful about buying erectile dysfunction medications online, as there is a lot of fraud.
