Viagra, whose active ingredient is sildenafil citrate, is a drug used primarily to treat erectile dysfunction (ED) in men. It was developed by the pharmaceutical company Pfizer and received FDA approval in 1998. Viagra works by increasing blood flow to the penis, helping men achieve and maintain an erection sufficient for sexual activity.
It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. When sexually aroused, the body releases nitric oxide in the penis, which activates an enzyme that produces cyclic guanosine monophosphate (cGMP). This cGMP relaxes the smooth muscle cells in the blood vessels, allowing them to dilate and increase blood flow. PDE5 inhibitors such as Viagra prevent the breakdown of cGMP, thereby improving and prolonging the erection.
Viagra is usually taken as a tablet about 30 minutes to an hour before sexual activity, although it can be effective from 15 minutes to four hours after ingestion. The recommended starting dose is usually 50mg, but this can be adjusted to between 25mg and 100mg based on efficacy and tolerability.
Although Viagra is effective for many men, it is not without side effects. Common side effects include headache, flushing, indigestion, stuffy nose, dizziness and vision problems. Rare but serious side effects include sudden hearing loss, heart attack symptoms and priapism, a prolonged and painful erection that requires immediate medical attention.
Viagra is not suitable for everyone. Men taking nitrates for chest pain or those with certain medical conditions such as severe heart or liver problems should not use it. It is important to consult a healthcare professional to ensure that Viagra is safe and appropriate for individual use.
Overall, Viagra has been a groundbreaking treatment for erectile dysfunction, providing an effective solution for millions of men worldwide to improve their sexual function and quality of life. However, it is not available without a prescription.
Yes, Viagra can sometimes have no effect. This can be due to various factors such as incorrect usage, underlying medical conditions, or certain medications that interfere with its effectiveness. It's best to consult a healthcare provider for guidance. Weaker effect can be caused by certain factors, but if you follow the instructions and recommendations, you eliminate the risk of reduced effect.
The factors that influence the effect include:
Viagra, like other drugs used to treat erectile dysfunction, can cause side effects. Common side effects include headache, flushing, indigestion, stuffy nose, dizziness and blurred vision. More serious but rare side effects include sudden hearing loss, heart attack symptoms and prolonged erections (priapism), which require immediate medical attention. However, every man treated for erectile dysfunction experiences the drug in a different way, so it is important to be aware of any unwanted side effects. It's important to use Viagra under medical supervision to effectively manage potential risks and side effects.

It is inadvisable to combine two or more distinct pharmaceutical agents for the treatment of erectile dysfunction. Such an approach could result in an overdose of the active ingredient, sildenafil citrate, with a maximum daily dose of 100 mg, which is the quantity present in a single tablet. In the event that a patient is taking Viagra for the first time, it is recommended that they commence with a smaller dose of 25 or 50 mg. This will minimise the risk of adverse effects and the potency of the medication should remain unaltered. It is recommended that Viagra be taken on an empty stomach in order to achieve the optimal effect. It is advisable to be aware of or to consult with a medical practitioner regarding potential drug interactions with the medication in the event that other prescription drugs are being taken concurrently. Given that Viagra exerts an effect on blood pressure, it is of the utmost importance to regulate the utilisation and combination of pharmaceuticals.
Generic Viagra, also known as Sildenafil, is a cost effective alternative to the brand name medication. It contains the same active ingredient and works similarly to treat erectile dysfunction. Available in a variety of strengths, Generic Viagra is just as effective and has been approved for safety and efficacy. Choosing the generic version can provide significant savings while ensuring the same therapeutic benefits as the brand name option.
