Whether Adding Vitamin D to Tadalafil 5 mg Treatment Is Useful in Patients with Erectile Dysfunction and Vitamin D Deficiency? Folic acid supplementation improves erectile function in patients with idiopathic vasculogenic erectile dysfunction by lowering peripheral and penile homocysteine plasma levels: a case-control study. Sildenafil is used to treat erectile dysfunction (also called sexual impotence). Sildenafil belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors. These medicines prevent an enzyme called phosphodiesterase type-5 from working too quickly. When hypertension occurs in the lungs, the heart must work harder to pump enough blood through the lungs.
| Parameter | Value | Unit | Notes |
|---|---|---|---|
| Tmax (Time to peak) | 30-60 | minutes | When the maximum plasma concentration occurs |
| Half-life | 4-5 | hours | Duration of drug activity |
| Bioavailability | 40-50 | % | Fraction of drug absorbed into circulation |
| Onset of Action | 15-30 | minutes | Time until effect begins |
Sildenafil works on the PDE5 enzyme in the lungs to relax the blood vessels. This will increase the supply of blood to the lungs and reduce the workload of the heart.

However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving sildenafil.

Usual Pediatric Dose for Pulmonary Hypertension
In very large quantities, it would be toxic for humans.32 Of course, that would be a much higher quantity than the amount in cereal or in BlueChew. Nonetheless, if you already consume many foods and drinks containing Blue No. 1 or use cosmetic products containing it, adding another source could marginally increase your cumulative risk of experiencing a couple of irritating side effects like skin rash or cough.32 In terms of inactive ingredients for the purpose of flavoring, BlueChew’s products variably contain: Natural flavoring (fruit punch in sildenafil and tadalafil only) Xylitol poses no apparent risk of side effects.33 However, because of the connection between peppermint and reflux symptoms for some who suffer from GERD, those with GERD may wish to avoid the risk of any unwanted heartburn side effects from the peppermint added to BlueChew vardenafil chews.15 34 If you have GERD or hiatus hernia and have observed that peppermint or mint exacerbates your reflux symptoms, you’d be better off opting for BlueChew sildenafil or tadalafil — depending on what a prescribing medical professional concludes, of course — or choosing a more traditional form of vardenafil that isn’t minty. The PDE5 treatments available from BlueChew are available only by prescription for good reasons: they would pose an unacceptable health risk to some people, and for the rest of us, they may cause side effects that are disruptive enough that it’s important for a doctor to be involved in making adjustments to dosage or proposing a different PDE5 medication entirely. But thankfully, the medications in BlueChew have been widely used for decades, so there’s a long track record to study.

The penis is one of the areas where this enzyme works. Erectile dysfunction is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. When a man is sexually stimulated, his body's normal response is to increase blood flow to his penis to produce an erection. By controlling the enzyme, sildenafil helps to maintain an erection after the penis is stroked. Without physical action to the penis, such as that occurring during sexual intercourse, sildenafil will not work to cause an erection. When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below.
