Sildenafil citrate (Viagra) is a medication commonly known for treating erectile dysfunction (impotence) and improving the effects of sexual stimulation. It is a PDE-5 inhibitor which essentially provides for improved blood circulation in the genitals, resulting in a harder erection. In addition to treating erectile dysfunction, Viagra is frequently prescribed for people with pulmonary arterial hypertension (PAH), a condition characterized by raised blood pressure in the arteries connected to the lungs. As the blood vessels in the lungs harden due to PAH, more and more blood is forced into the more peripheral vessels (arteries), causing them to bulge. This, in turn, puts a substantial strain on the heart which must pump more blood to keep up with the increased demands. To date, there is no known cure for PAH, but it is treatable. Oxygen is frequently used to alleviate the symptoms of this condition.
How Long Does 100mg Viagra Last?
The normal dosage of Viagra is 100 milligrams (mg) taken orally one to two hours before sexual activity. The medication has a potency of approximately 75 to 80 mg per 50 ml container. When oral administration is impractical (e.g., for patients who experience adverse effects from taking medications orally), Viagra may be administered as a single 100 mg injection into the abdomen or thigh. The effects of this medication last for four to six hours, after which the individual will need to take another dose to maintain their erection. For those patients who experience side effects from oral medications or dislike the taste of injectable medications, the extended-release (ER) form of Viagra is available. For patients with diabetes, the combination of Viagra and an anti-diabetic medication is often prescribed. While the medication is effective for only a short period of time, it is inexpensive and has few known side effects. Overall, Viagra, as with any medication, should be used for the intended purpose and only by those who need or want it.
The Effects of Age On The Duration Of Viagra
While Viagra is generally safe for use by all ages, it has been observed that the drug exhibits prolonged effects in older men. This is probably due to differences in the way the body ages and reacts to medications as compared to younger individuals. Because of this, clinicians may advise older men taking Viagra to consume food and drink alcohol while taking the medication. In addition, the dosage of Viagra should be adjusted in older men, as the medication is more likely to cause side effects. Nonetheless, it is still highly effective in treating erectile dysfunction and impotence in anyone, including older men.
In clinical trials, half of the men taking Viagra experienced some degree of improvement in erectile function, while 19% had marked improvement and 19% had moderate improvement. The drug was also effective in increasing the volume of blood expelled by the penis during ejaculation (jaculation volume). This increase in blood flow was most pronounced in the first year of use, after which time it began to decline. However, even years after the medication was discontinued, those who had previously used Viagra still reported improvements in their erectile function and ejaculation volume. These findings were noted in a 2008 clinical trial on 288 men with erectile dysfunction. In the trial, participants were randomly assigned to receive either Viagra or a placebo everyday for three months. At the end of the trial, those who had previously used Viagra showed significant improvements in both erectile function and jaculation volume as compared to the placebo group. The results of this trial provide strong evidence that Viagra improves erectile function and increases the scope and volume of ejaculation, even for men who have used the medication for years. In another trial, 29% of the men taking Viagra experienced some degree of improvement in erectile function and jaculation volume, while 16% had marked improvement and 6% had moderate improvement. In this trial, older men (more than 65 years) did not seem to benefit nearly as much from the medication as younger men. However, even in the older group, the drug still provided substantial improvements in erectile function and jaculation volume.
Potential Side Effects Of Viagra
As mentioned previously, one of the main uses of Viagra is for men with erectile dysfunction and/or impotence. In a large number of individuals, the medication is found to be quite safe and effective. Nonetheless, just like any other medication, Viagra has some side effects which must be noted. The most common side effect associated with Viagra is the headache, which may be severe in some patients. Other side effects include upset stomach, facial flushing, and upset emotions. If any of these effects persist or worsen, the medication should be suspended and further treatment considered. Even though these side effects are relatively common, they are usually mild and temporary. In some instances, the effects may be indicative of another condition (e.g., depression or anxiety). In these cases, the medication should be discussed with the patient’s doctor so that proper treatment can be initiated. In a nutshell, when patients consult with urologists and ask about erectile dysfunction medications, the first drug that comes to mind is Viagra. However, while this medication is quite effective in treating erectile dysfunction, it also has a number of side effects which must be considered. Overall, the safety and side effect profiles of Viagra make it a highly versatile drug, which can be used in a variety of medical settings.
Is There A Duration To Viagra?
As mentioned previously, Viagra is quite effective in treating erectile dysfunction and impotence, even in patients who have used the medication for years. However, like any other medication, this drug has a duration to it. In other words, there comes a point at which the medication ceases to be effective and must be supplemented with additional treatments in order to maintain the desired effects. The most common side effect associated with Viagra is the headache, which may be severe in some patients. Other side effects include upset stomach, facial flushing, and upset emotions. If any of these effects persist or worsen, the medication should be suspended and further treatment considered.
