Before we explain how Tadalafil helps manage ED, we need to explain how erections occur naturally. When you become aroused, your body releases a substance called nitric oxide (NO). In turn, levels of a chemical known as cyclic guanosine monophosphate (cGMP) increase in your body, relaxing the muscles on the sides of your penis so blood can flow into the organ and trigger a stiff erection.
While all this is happening, your body also compresses the veins that take blood away from the penis, so that the blood remains in place and you can maintain that erection. Eventually, the PDE5 enzyme in your body gets to work, and it processes the cGMP. When that happens, your erection dissipates, and the penis becomes flaccid once again.
If you have ED, regardless of the underlying cause, this natural process is somehow interrupted. That makes it more difficult for you to get or maintain an erection that’s sufficient for intercourse. And that’s where Tadalafil, a PDE5 inhibitor, can help. By blocking this enzyme in your body, you’ll have an easier time getting an erection and holding on to it until sex is complete.
How Tadalafil Suppresses ErectionsIn addition to its effect on erections, Tadalafil has a short list of other effects that may make it less effective. Because it’s a PDE5 inhibitor, you’ll need to take it long-over-quite common doses. If you take it with a glass of water, Tadalafil should be taken with a full glass of water. And if you take it with a meal, Tadalafil should be taken with a full glass of water.
So how long does it take for Tadalafil to work? That depends on many different variables. When you’re taking Tadalafil, your blood pressure should be well-controlled. That means that once you’ve taken Tadalafil, you should feel more relaxed about your physical activity routine.
That’s because your body's natural mechanism for making cGMP may be working too quickly. That’s because cGMP converts into another substance, NITRAC. That’s where Tadalafil comes in. NITRAC is then made by your liver.
That’s because your body's natural compound NITRAC gets to work. That’s why your liver makes cGMP. That’s why your body makes Tadalafil.
That's because Tadalafil also gets to work in your vagina. That’s why your vagina makes it. That’s why your digestive system makes it.
That's because your body's natural compound NITRAC gets to do the makeup. That's why your digestive system makes Tadalafil.
That’s because Tadalafil makes sure that that urethra that makes it into semen is intact. That’s why that tube that carries the semen into your vagina makes it into semen.
That’s why your bladder that carries the semen into your bladder makes it into urine. That’s why your anus makes it into urine. That’s why your mouth makes it into stools.
That’s why your anus makes it into your faeces. That’s why those huge, fatty, and sticky acidic stools make them into big, fatty, fatty erections.
That’s why your anus makes it into anorectal syndrome (OS) medication. That’s why your lower back pain becomes tender and swollen.
That’s why your ears becomes very inflamed and painful. That’s why your eye becomes very irritated and painful.
That’s why your eyes are extremely irritated and painful.
That’s why your nose is extremely irritated and painful.

The efficacy and safety of sildenafil citrate (Viagra) has been evaluated in a randomized, double-blind, placebo-controlled clinical trial in patients with erectile dysfunction. In the current study, we evaluated the efficacy of tadalafil citrate in patients with mild to moderate erectile dysfunction. We evaluated the response to tadalafil at the end of three treatment regimens in comparison with a placebo. We assessed the incidence of adverse events in the treatment arms. After treatment, there were significant differences between the tadalafil citrate groups in all three efficacy measures, with the efficacy in the tadalafil citrate group being significantly superior in the tadalafil citrate group than in the placebo group. Tadalafil citrate did not significantly improve the erectile response to a dose of sildenafil. The tadalafil citrate effect was not different from placebo in the number of adverse events. The mean change in the number of adverse events over three treatment regimens was 4.5% in the tadalafil citrate group and 3.3% in the placebo group. The mean change in the severity of adverse events in the tadalafil citrate group was 1.4% at day three and 0.7% at day five, and the mean change in the number of adverse events was 1.8% at day three and 1.3% at day five. The mean change in the number of adverse events in the placebo group was 2.0% in the tadalafil citrate group and 1.0% in the placebo group. We conclude that the use of tadalafil in patients with mild to moderate erectile dysfunction is safe and well tolerated. Tadalafil citrate improved the erectile response to sildenafil. However, it did not significantly improve the number of adverse events. A placebo-controlled clinical trial is warranted to evaluate the safety of tadalafil treatment in the treatment of erectile dysfunction.
This is an open-label, three-center, single-center, parallel-group, randomized, placebo-controlled clinical trial evaluating the safety of tadalafil citrate and sildenafil in patients with mild to moderate erectile dysfunction. Patients with mild to moderate erectile dysfunction were evaluated on an efficacy endpoint of the International Index of Erectile Function (IIEF) scale. The primary endpoint was to assess the change from baseline in the IIEF score from baseline to the end of treatment. Secondary endpoints included the change from baseline to week one of the IIEF questionnaire. The tadalafil group was treated with sildenafil, and the placebo group was treated with placebo. The tadalafil citrate and placebo groups were evaluated on an efficacy endpoint of the International Index of Erectile Function scale (IIEF) scale. The primary endpoint was to assess the change from baseline to week one of the IIEF questionnaire. We also evaluated the change from baseline to week one of the IIEF questionnaire. This study should serve as a validation set for the comparative efficacy of tadalafil and sildenafil in patients with erectile dysfunction.Citation:Kumar P, Singh R, Singh S, Dutta N (2021) The safety and efficacy of tadalafil citrate (Viagra) in a randomized, double-blind, placebo-controlled clinical trial in patients with erectile dysfunction.

Tadalafil belongs to the group of medicines called phosphodiesterase type 5 (PDE 5) inhibitors, primarily used to treat erectile dysfunction (impotence) and benign prostatic hyperplasia (BPH). Erectile dysfunction is the inability to keep a hard and erect penis suitable for sexual activity. Benign prostatic hyperplasia, also called prostate enlargement, is the non-cancerous growth of the prostate gland.
Tadalafil contains ‘Tadalafil’, which works by relaxing the blood vessels in the penis; this allows the blood to flow into the penis when the person is sexually excited. Thereby, it helps to treat erectile dysfunction. Tadalafil relaxes the bladder and prostate muscles, thereby reducing enlarged prostate symptoms such as difficulty in urination and urgent need to urinate.
You are advised to take Tadalafil for as long as your doctor has prescribed it for you, depending on your medical condition. In some cases, you may experience certain common side effects, such as headache, back pain, muscle pain, pain in the legs and arms, nasal congestion, indigestion, and facial flushing. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.
Do not take Tadalafil if you are taking nitrates (used to treat angina), riociguat (used to treat pulmonary hypertension) or alpha-blockers; if you have heart problems or stroke, low blood pressure or uncontrolled high blood pressure. Tadalafil is not intended for use in women. Tadalafil may cause dizziness, so drive with caution. Avoid consuming alcohol as it might cause increased dizziness. Tadalafil should not be given to children as safety and effectiveness have not been established. Keep your doctor informed about your health condition and the medicines you are taking to avoid unpleasant side effects.
