Viagra: Understanding the Aspects of the Famous Drug

viagra (sildenafil)Erectile dysfunction is a relatively common condition which limits a man’s ability to maintain or even get an erection for sexual activity. This issue can be caused or accelerated by diverse factors including psychological disorders, stress, aging, medical problems or even an unhealthy lifestyle in general.

Fortunately, impotence can be rectified through the use of pharmaceutical products. There are numerous products that are sold in pharmacies in the UK to manage ED, but the most well-known option is definitely Viagra. This drug is highly effective and has a good safety profile in comparison to its alternatives. Here are the important aspects of Viagra that you should understand.

The Active Ingredient in Viagra

The active ingredient which is used in the manufacture of Viagra is sildenafil. While the compound has been available for a while, it became a common treatment for ED around 1998. Basically, this active ingredient works by affecting a particular enzyme which is responsible for regulating the blood flow to the penis. The action of the compound is only activated through sexual stimulation, so sildenafil does not cause erections indiscriminately after consumption. Like most approved ED medications in the UK, Viagra is a tablet that is administered orally.

Standard Dosage Information

For the best action of the medication, it is crucial to take the right dosage of Viagra. If the quantity is too low, the results will be unsatisfactory, while an overdose can cause some adverse effects. Generally, Viagra is available in three different dases: 25, 50, and 100mg. For most of the patient, the ideal and recommended dose is 50mg. However, the level of tolerance and general effectiveness can cause the doctor to adjust the dosage to either 100mg or 25mg. The maximum dosage frequency as recommended by physicians is one tablet per day, so this threshold should be observed for safety purposes.

In ideal circumstances, you should take Viagra approximately one hour before your planned sexual activity. When this is not possible, there is no harm in taking the medication within the range of thirty minutes and four hours. Sildenafil will be available in sufficient levels in your bloodstream during this period. You can take the drug with or without food, depending on your preference. However, keep in mind that a hearty meal can delay the effect.

Precautions and Contraindications

You should always discuss any pre-existing medical conditions with your doctor before taking Viagra. In addition, you should provide a complete list of any other medications and supplements that you might be taking. This information is critical in adjusting the dosage and preventing adverse interactions for special populations in order to enhance efficacy while ensuring patient safety. For example, it is recommended for the dosage to be lowered to 25mg as opposed to 50mg for people over the age of 65 and those with kidney and liver disorders. This is because the declined performance of their bodies will cause a higher level of sildenafil in the blood.huzzah! erection

Also, proper care should be taken with regard to drug interactions. For instance, some medications such as erythromycin, ketoconazole and protease inhibitors for HIV will prolong the presence of sildenafil in the system.

Viagra should not be used by certain categories of people due to the potential negative effects of the drug on them. Patients with circulatory disorders such as hypertension and heart disease as well as those who have suffered stroke and cardiovascular conditions will compromise their physical well-being by taking Viagra. The drug is broken down and excreted by the liver and kidneys. Therefore, if you have hepatic or renal impairment, you should avoid the medication. Finally, Viagra should never be taken together with nitric oxide donors or nitrites and nitrates for medical safety.

Also, Viagra is known to affect blood pressure, so at-risk people are not allowed to take the drug without consulting the doctor first.

Side Effects

There are some adverse effects that have been associated with Viagra. The most common ones are relatively mild and include indigestion, nasal congestion and headaches. Patients might also experience flushing and vision problems such as blurring and sensitivity to light. In addition to these, there are some rare cases where the side effects are serious. Prolonged erections and sudden hearing loss might be experienced in some rare cases.
