Viagra was shown to initiate the hypotensive effects of nitrates and its administration in patients that consume nitric oxide donors such as organic nitrates or organic nitrites in any form.
When Viagra is co-administered with an alpha-blocker, users should be stable on alpha-blocker therapy before initiating Viagra treatment; it should be initiated at 25 mg.
Along with its required effects, Viagra may cause some adverse reactions to those who misuse it or don't follow any instructions.
The most common side effects include headache, flushing, nasal congestion, indigestion, and impaired vision, including photophobia and blurred vision. Some Viagra users have complained of seeing everything tinted blue.
Patients thus taking the drug may experience color vision abnormalities. Rare but serious adverse effects found by postmarketing surveillance include prolonged erections, severe low BP (blood pressure), ventricular arrhythmias, stroke, myocardial infarction, increased intraocular pressure, & sudden hearing problems or loss.
Sexual activity can strain your heart, especially if you have heart problems. If you feel severe dizziness, fainting, chest/jaw/left arm pain, or nausea while having sex, stop right away and seek clinical attention immediately.
Sometimes, a sudden decrease in vision, including permanent blindness, might occur in one or both eyes.
You may have a slightly greater chance of developing permanent blindness if you have diabetes, heart disease, high cholesterol, high BP (blood pressure), or are over 50 years of age.
A sudden loss of hearing may also occur.
In rare cases, you may have a prolonged erection lasting four hours; in that case, you should immediately stop using this drug and get medical help directly. You must be cautious after you get Viagra 100mg online.
Viagra protects cyclic guanosine monophosphate (cGMP) from degradation by a cGMP-specific phosphodiesterase type 5 (PDE5) in the corpus cavernosum.
Nitric Oxide in the penis' corpus cavernosum binds to guanylate cyclase receptors, causing levels of cGMP to rise. This causes smooth muscle relaxation or vasodilation of the helicine arteries' intimal linings.
This smooth muscle relaxation resulted in vasodilation and increased blood flow into the spongy tissue of the penis, causing an erection. The molecular mechanism of smooth muscle relaxation includes the enzyme cGMP-dependent protein kinase, also called PTKs.
This kinase is further activated by cGMP, and it generally phosphorylates multiple targets in the smooth muscle cells, namely myosin light chain phosphate, RhoA, IP3 receptor, phospholipase C, and others. Overall, this reduces intracellular calcium and desensitizes proteins to the reactions of calcium, engendering smooth muscle relaxation.
Viagra is a potent and selective inhibitor of cGMP-specific phosphodiesterase type 5 (PDE5), which is used for the degeneration of cGMP in the corpus cavernosum. Its molecular structure is similar to that of cGMP.
It acts as a competitive binding agent of PDE5 in the corpus cavernosum, leading to more cGMP and increased penile response to sexual stimulation.
Without sexual stimulation, there is a lack of activation of the NO/ cGMP system; Viagra should not cause an erection. Other drugs that operate by the exact mechanism include tadalafil and vardenafil.
Viagra reaches its maximum plasma concentration by around one hour, and the maximum concentration is decreased by nearly one-third.
