Viagra, Cialis and Levitra- three main impotence fighters give warnings to the users that these medications all PDE5 inhibitors can cause vision changes such as blurring, sensitivity to light and a bluish hue.
Since 2005 FDA and the manufacturers warn the doctors and patients about the possibility of more serious side effects. These warnings appeared after several reports of sudden vision changes, vision problems and loss of vision in patients. FDA suggested the possible relation between Viagra and other PDE5 inhibitors and sudden blindness from the rare condition known as non-arteritic ischaemic optic neuropathy (NAION). This eye disorder is characterized by poor blood supply to the optic nerve resulting in permanent nerve damage.
FDA provided information about all cases of sudden blindness caused by all PDE5 inhibitors. In the report it was noted that 38 users of Viagra and 5 users of other ED oral medications had experienced a sudden and permanent vision loss in one eye – NAION. The agency focuses on the fact that these events do not give direct evidence to a relation between ED medications and sudden vision loss; still doctors should warn their patients about this serious side effect especially if patients have certain pre-existing eye conditions.
Experts still are not sure if PDE5 inhibitors including Viagra induce a significant risk of vision loss. Pfizer has added extra information about this side effect to Viagra label. However, Pfizer experts are certain that males taking Viagra or other PDE5 inhibitors are at no bigger risk for vision loss than males of similar age and health conditions who do not use these medicines.
Pfizer confirms that this adverse reaction has not occurred in any of 103 clinical trials of Viagra in which about 13,000 patients took part. Besides, the company says that the 23 million users in the US have not reported a larger risk of vision loss.
Recent studies have shown that regular smoking escalates the chances for impotence up to 50% in men. On the basis of these chances and the widespread of this habit in men of different ages, the researchers evaluated that about 50% of men who are regular smokers suffer from erectile dysfunction in their 30s and 40s as a result of smoking. This figure tends to be misjudged due to the fact that it does not comprise ED cases of previous smoking in men who quitted. Besides, smoking results in a decreased volume of ejaculate, a decreased number of sperm, sperm changes and a poor response to any fertility therapies.
It is proved that smoking leads to heart diseases by damaging blood vessels supplying human heart. Erection problems in men who smoke may be warning signs of already damaged blood vessels and other organs of the body.
Cigarette smoke includes about 4000 chemicals which afflict vascular system disorders. Concerning the penile area these chemicals affect the arteries and veins that bring blood to the penis. An erection process involves the mechanism of blood inflow into the penis resulting in the hardening of the penile tissue that squeezes the veins not allowing the outflow of blood from the penis. Smoking can negate this process by blood inflow reduction in more than 20% of men. This is associated with atherosclerosis of specific penile arteries brining the blood to the penis.
Nicotine forces the penile tissue to restrict due to the nicotine effect on the brain, which in turn affects the arterial blood flow to the penis. The negative effect of smoking on erectile function is associated with poor blood supply to the penis caused by smoking.
Venous dilatation often happen due to the impaired blood flow and as a result blood flows out of the penis more quickly thus making it hard to achieve and keep an erection. Stopping smoking could result a quick enhancement in the sexual function. Think about your health and your sexual abilities, stop smoking for good.
Lots of men with ED, who are hesitant to open their problems to doctors or partners, do not like to go and buy these medications at local pharmacies, prefer buying oral medications for the treatment of impotence at online pharmacies. This helps keep their condition in secret and purchase drugs without prescription.
Still it is recommended to visit a doctor for consultation to be sure that the medication you wish to order online will be safe and effective therapy for you.
A great number of web-sites, online pharmacies offer prescription medications for sale. Legal authorized virtual pharmacies often provide cheaper prescription medications than local pharmacies, besides they do it privately and quickly. However, if you buy online you should take special care and forethought that you get safe approved medications from a trustworthy pharmacy.
Buying medications from an unofficial and unlicensed site can cause dangerous consequences to health. Unlicensed pharmacy very often sells products containing dangerous unsafe components or counterfeits and imitations. Besides, unfair online pharmacies may open your personal and financial information to others.
Prudence should prevail when buying medicines without prescription online. You should start with scrupulous investigation of all the information about online pharmacy you wish to make a purchase at. An online pharmacy should be registered in the country it is originated from, the payments should be processed via a secure server, no hidden costs should present, and all custom rights of a consumer should be respected.
The success of male erectile dysfunction therapies such as Viagra has increased the concern of development the drugs for sexual dysfunction in women. Different studies confirm that women more often than men have sexual dysfunctions, it was estimated that 43 % of women experienced sexual difficulties in comparison to 31 % of men. Therefore many women look for a solution for their lack of sexual desire and use drugs for men such as Viagra.
Many researchers claim that sexual disorders in women are more complicated than in men, and it’s doubtfully that Viagra will have any effect for women. During 8 years Pfizer Inc. conducted a great work involving 3,000 women and finally stopped any attempts to establish that Viagra can help to solve sexual problems in women. It seems that Viagra can have effect on women such as sexual arousal but it has no effect on the desire to have sex. The medication does not increase sexual desire, it provides the ability to get and maintain an erection. The basic difference between men and women is different association between arousal and desire. Arousal in men always leads to sexual desire. Viagra improves a man’s ability to have erections and thus enhances his sexual function. In women arousal and desire are often incoherent.
Women have disconnected sexual genital arousal and arousal in brain. The brain plays the fundamental role for sexual desire in women.
There is little or no proves that Viagra can help women who like to enhance their sexual life and desire, but some doctors think that Viagra may help pregnant women with placental insufficiency. For such pregnant women Viagra may be used to improve blood supply to the uterus.
A new study of Sildenafil was conducted by a group of researchers including two representers of Pfizer. According to this study the active ingredient of Viagra –Sildenafil could help children with pulmonary arterial hypertension, a rare condition which causes extremely high blood pressure in the arteries going to the lungs. This serious condition usually limits the physical ability and may result in heart failure or be even fatal if not treated properly.
The study involved 105 children in the ages from 1 to 17 years of old with pulmonary arterial hypertension which received a placebo or low, medium or high doses of Sildenafil. It was proved in previous studies of Sildenafil that it improved oxygen delivery and exercise tolerance, so it is used to treat pulmonary arterial hypertension in adults. The new research has shown that children who received Sildenafil were able to exercise at the end of the study. It has been also demonstrated that children taking Sildenafil had more improvement in lung function than those who took the placebo. Actually the medium dose of Sildenafil has appeared to be safest and most effective.
The drug has not been yet approved by U.S. FDA for the use in pediatric patients. More research is needed especially in the circumstances that the medication cause serious side effects such as priapism and others.

Obesity can cause ED because of many diseases which accompany extra weight, like diabetes, kidney disease, hypertension, heart disease and alcoholism. These serious diseases reduce the blood flow to the penis.
Diabetes is one of the most usual afflictions for development of impotence. High level of blood sugar, cholesterol, hypertension, smoking and drinking are the common characteristics of an obese man. All these factors influence negatively on the blood vessels thus producing impotence. If a person has an extra weight, he is more likely to face the problem of heart disease, diabetes, stroke, cancer, gout, gallbladder disease and impotence.
