Viagra is a prescription medication for erectile dysfunction, a condition in which men cannot achieve or sustain an erection for sexual activity. In Australia, Viagra is a medication that works by helping to relax the muscles in the blood vessels, allowing more blood to flow into the penis during sexual stimulation. The active ingredient in Viagra is sildenafil citrate, which has been approved by the Australian Therapeutic Goods Administration (TGA) as a treatment for erectile dysfunction. This allows for increased blood flow to the penis, helping men achieve and sustain an erection. The active ingredient in Viagra is sildenafil citrate, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor, which means it works by helping to relax the blood vessels in the penis, allowing more blood to flow into it.

How does the drug interact with Viagra tablet:Combining Viagra can increase the risk of developing erectile dysfunction and sexual performance issues.How to manage the interaction:Viagra is generally well-tolerated but should not be used with medicines that act on its function.How it works:Medications that affect the enzyme phosphodiesterase type 5 (PDE5) enzyme increase the levels of a chemical in the body, resulting in an increased likelihood of an interaction. PDE5 inhibitors act on PDE5 enzymes to inhibit, block, or increase levels of the enzyme. These inhibitors act by blocking the action of the PDE5 enzyme, thereby decreasing the level of the enzyme, and this in turn may result in an increased risk of conditions such as sexual performance issues like erection problems.
Viagra is generally well-tolerated but should not be used with medicines that affect the enzyme phosphodiesterase type 5 (PDE5).Medications that affect the enzyme phosphodiesterase type 5 (PDPE5) enzyme increase the levels of a chemical in the body, resulting in an increased likelihood of an interaction. PDE5 inhibitors act on PDE5 enzymes to inhibit PDE5, to give men a lower risk of an interaction with an interaction. PDE5 inhibitors also act on cGMP, an effect that is increased with the use of Viagra.This combination may result in a lower risk of an interaction, but it may result in an interaction that is more likely to occur. Therefore it is always advised to consult a doctor before using Viagra if you have any of the following health problems: kidney problems, pregnant complications, or vitamins. Do not use Viagra if you are allergic to cGMP or if you are pregnant. Do not use Viagra if you are breastfeeding, taking medicine in your digestive system, if you have any problems with your liver or kidneys, if you are anuria, severe liver problems, an allergic reaction to this or any other medicines, if you are a patient with a heart problem, or if you have any of the following conditions: problems with how over the counter a medicine like a drug for high blood pressure or congestive heart failure, liver problems, problems with the flow of blood to your penis or kidneys, chest pain or pressure in the lower body, heart rhythm problems (arrhythmias), retinitis pigmentosa (an inherited skin condition that causes sickle cell cancer), severe stomach problems, ulcers, heart failure, or fatty liver. cGMP is also increased with the use of Viagra.Co-administration of Viagra and sildenafil with this medicine increases the risk of developing erectile dysfunction.Viagra and sildenafil are vasodilators that lower the level of cGMP in the body. This may result in an increased risk of an interaction. cGMP may also increase the effect of nitrates, such as nitroglycerin, on the flow of blood to the penis. When Viagra and sildenafil are taken with Nitrates, men who take these may face an interaction that can occur.Viagra and sildenafil may be used for the treatment of the same condition. However, there may be a possible risk of combining these medicines, which may lead to serious side effects, if Viagra and sildenafil are taken together. Combining Viagra and sildenafil may increase, or cause an interaction with medicines that affect the enzyme PDE5.Nitrates used to treat heart conditions like nitrates may lower the level of cGMP and may also increase the effect of sildenafil, or of medications that affect these enzymes, which may therefore lead to an interaction.Viagra and sildenafil are used in the same way as Viagra because they may possibly further increase the risk of erectile dysfunction and may lead to a small amount of blood being drawn to cause side effects. However, they must be used at the same time to achieve the best blood pressure response. Doctors advise that they should be used in close contact with one another and not more than that in order to avoid any interaction that may occur.
