An average blood pressure reading of more than 140/90 lies under the category of high blood pressure. High blood pressure occur when the pressure within blood vessels is too high and if it is not treated in time, then that can result in some serious repercussions, such as heart attack and kidney failure. It is available under the brand name of Adcirca to avoid the confusion with Cialis, it works by blocking phosphodiesterase-PDE5 enzyme in the body. This helps to relax the blood vessels in the lungs. Decreasing high blood pressure in the lungs allows the heart and lungs to work better.

Another use of it is to treat Raynaud’s Phenomena where the blood vessels in the fingers, toes, ears, and nose gets narrowed it is called Vasospastic Attack. Raynaud’s phenomenon can either occur on its own, or it can be secondary to another condition, such as scleroderma. Adricia is also prescribed here though it is not an approved way of treatment but it does works well, as its core function is the inhibition of PDE5 enzyme that make the contracted vessels relax.

The main ingredient of Cialis is substance of, Tadalafil code named IC351, belongs to a group of medicines called ‘phosphodiesterase type 5 (PDE5) inhibitors’. It works by blocking the phosphodiesterase enzyme, which normally breaks down a substance known as cyclic GMP (cGMP). During normal sexual stimulation, cGMP is produced in the penis, where it causes the muscle in the spongy tissue of the penis (the corpora cavernosa) to relax, allowing the flow of blood into the corpora, producing the erection. By blocking the break down of cGMP, Cialis restores erectile function. However, sexual stimulation is still needed.

Cialis was used on women who used Serotonin excessively which resulted in sexual dysfunction in women. Three women with medication-induced sexual dysfunction derived benefit from using 20 mg of Cialis before anticipated sexual activity. It countered the effect created due to increased intake of Serotonin drugs.

It was witnessed in one of the researches that were to investigate the usual side effects of back pain and/or myalgia to understand its mechanism and reason to occur. An integrated analysis of 10 placebo-controlled Cialis clinical trials showed that the incidence of back pain and/or myalgia was 9% in patients receiving Cialis 10 mg, 8% in patients receiving Cialis 20 mg and 3% in placebo-treated patients. Although the mechanism of back pain and/or myalgia remains unknown, these Cialis side effects appear to be self-limiting and a general effect of phosphodiesterase 5 inhibition.

There has been many talks of not taking any medication while you are on Cialis as that can be very dangerous. But what if it is inevitable; here one such study is discussed where the hypertension is discussed and its first line therapy Thiazide reaction to Cialis.. Data was analyzed from 14 randomized, double-blind, placebo-controlled trials to evaluate the efficacy of Cialis 20 mg for the treatment of ED in men on Thiazides. Of the 2501 patients, 163 were on concomitant Thiazides (116 Cialis /47 placebo) and 159 (98%) were reported to have hypertension. The Cialis group showed a significantly greater mean baseline to endpoint improvement on all efficacy outcome measures compared to placebo-treated patients regardless of concomitant Thiazide use. More importantly, the responses to Cialis were similar regardless of concomitant Thiazide use.

The erection of penis and its rigidness during sexual stimulation is the direct result of the increased flow of blood through chambers corpora cavernosa; one for inflow and other for outflow that causes the loss of erection. This accumulation of blood is caused due the relaxation of muscles of corpora cavernosa that is implemented through the occurrence of certain chemical reactions where the nerve terminal releases Nitric Oxide and endothelial cells, which provides the enabling environment to inhibit the enzyme and thus the muscles remain relaxed and the accumulated blood does not exit through the outflow chamber of corpora cavernosa. Now what Cialis does is that it inhibits the enzymes that are responsible to make the corpora cavernosa muscles to contract and let the out flow of blood from the penis possible by not letting the chemical reaction to occur.
