Tadalafil’s pharmacological distinction is its longer half-life (17.50 hours) - resulting in a longer duration of action, and so is partly responsible for “The Weekend Pill” sobriquet. Penile erection during sexual stimulation is caused by increased penile blood flow resulting from the relaxation of penile arteries and the smooth muscle of the corpus cavernosum. This response is mediated by the release of nitric oxide (NO) from the nerve terminals and the endothelial cells, which stimulate synthesis of cGMP in the smooth muscle cells. Cyclic GMP relaxes smooth muscle and increases blood flow to the corpus cavernosum. Use of Cialis Tadalafil does not protect against sexually transmitted diseases.

Different drugs work differently for every individual so you may need to try several. One popular drug for erectile dysfunction is Viagra SoftTabs as well as the generic version.

Erectile dysfunction drugs may be better than nitroglycerin in protecting the heart from damage before and after a severe heart attack, Virginia Commonwealth University researchers report.

During a heart attack, the heart is deprived of oxygen, which can result in significant damage to heart muscle and tissue. After the attack, most patients require treatment to reduce and repair the damage and improve their chances of survival. With the exception of early reperfusion, there are no available therapies that are truly effective in protecting or repairing such damage clinically.

Rakesh C. Kukreja, Ph.D., professor of medicine and Eric Lipman Chair of Cardiology at VCU, and colleagues compared nitroglycerin with three erectile dysfunction drugs: Viagra, generically known as sildenafil, Levitra, generically known as vardenafil, and Cialis online pills — to determine the effectiveness of each for heart protection following a heart attack. Nitroglycerin is a drug used to treat angina, or chest pain. It is a vasodilator and opens blood vessels in order to improve the flow of blood to a patient’s heart.

The research team reported that in an animal model, generic viagra online and generic levitra online reduce damage in the heart muscle when given after a severe heart attack. In contrast, nitroglycerin failed to reduce the damage in the heart when administered under similar conditions. The findings were published in the February issue of the Journal of Molecular and Cellular Cardiology, the official publication of the International Society for Heart Research.

“Erectile dysfunction drugs can prevent damage in the heart not only when given before a heart attack, as we discovered previously, but also lessen the injury after the heart attack,” said Kukreja, who is the lead author of the study.

According to Kukreja, the protective effects on the heart produced by these erectile dysfunction drugs may be potentially useful as adjunct therapy in patients undergoing elective procedures, including coronaryartery bypass graft, coronary angioplasty or heart transplantation. In addition, he said another potential application could be to prevent the multiple organ damage that occurs following cardiac arrest, resuscitation or shock.

“Preserving heart function is critical to optimal cardiac outcomes,” said George W. Vetrovec, M.D., chair of cardiology at the VCU Pauley Heart Center. “These agents have significant potential to enhance patient outcomes, particularly in high risk circumstances, such as acute heart attacks.“

For several years, Kukreja and his colleagues have studied a class of erectile dysfunction drugs known as phosphodiesterase-5 inhibitors as part of ongoing research into heart protection. The team first investigated viagra, and then cialis, and found that both compounds were protective when given before a heart attack under experimental conditions.
