What Is Viagra

Sildenafil, commonly known by the brand name Viagra, is a medication widely used across Australia to treat erectile dysfunction. The active ingredient in Viagra, sildenafil, belongs to a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil tablets provide a reliable solution by enhancing blood flow to the penis during sexual stimulation, with effects typically lasting up to four hours.

How Does Viagra Works In The Body

Sildenafil works by inhibiting phosphodiesterase type 5 (PDE5) in the corpus cavernosum of the penis. This inhibition leads to increased levels of cyclic guanosine monophosphate (cGMP), which promotes smooth muscle relaxation in the penile tissues. The relaxation of these muscles allows for greater blood flow into the penis during sexual arousal. What makes sildenafil effective is its selective action on PDE5 enzymes, which break down cGMP, and this is essential for maintaining an erection. By blocking these enzymes, sildenafil helps maintain higher cGMP levels and supports sustained blood flow to achieve and maintain an erection. When a man is sexually aroused, nitric oxide is released in the erectile tissue, stimulating the production of cGMP.

Viagra Dosage

Viagra tablets in Australia are available in 25mg, 50mg, 100mg, and sildenafil 200mg for specific cases. Recommended starting dose is 50mg taken approximately one hour before sexual activity. The maximum recommended frequency is once per day, regardless of the strength. Taking more than the prescribed amount will not improve effectiveness but may increase the risk of side effects. Sildenafil 200mg is generally reserved for cases where lower doses have proven insufficient, and should only be taken under specific medical guidance. Elderly patients (over 65) or those with liver or kidney impairment may be started on a lower dose of 25mg, as their bodies may process the medication more slowly. Never adjust your dosage without consulting your doctor.

Viagra Effect Duration

Viagra effects starts within 30-60 minutes and last 3-4 hours, after taking Viagra pills. High-fat meals may delay absorption and onset of action by up to an hour.

The half-life of sildenafil (the time it takes for half the drug to be eliminated from the bloodstream) is approximately 4 hours. After 8-12 hours, most of the medication has been cleared from the system, though trace amounts may remain for up to 24 hours.

How To Use Viagra

Viagra should be taken approximately 30-60 minutes before sexual activity. Swallow the tablet whole with a full glass of water, and avoid crushing or breaking it.Cconsuming it on an empty stomach typically results in faster absorption and quicker onset of action. High-fat meals may delay the medication's effects by up to an hour and potentially reduce its effectiveness. Grapefruit and grapefruit juice should be avoided as they can increase blood levels of sildenafil, potentially enhancing side effects.

For elderly users, sildenafil should be used with additional caution. Men over 65 often metabolize the drug more slowly, which may lead to higher blood concentrations and increased sensitivity to both therapeutic effects and side effects.

Viagra Side Effects

Most common side effects are mild and transient, typically resolving within a few hours as the medication leaves your system. Viagra side effects in Australia are monitored by the Therapeutic Goods Administration, which regulates medication safety across the country.

Viagra and Alcohol

Alcohol is a vasodilator that lowers blood pressure, as is sildenafil. When used together, they can cause a dangerous drop in blood pressure, leading to dizziness, fainting, headaches, and increased heart rate. Also, alcohol consumption can worsen potential side effects of viagra, particularly headaches and facial flushing. Alcohol acts as a depressant on the central nervous system, which can counteract the effectiveness of sildenafil by reducing sexual arousal and sensation
