Sildenafil, also known by the brand name Viagra, is a revolutionary medicine that transformed the treatment of Erectile Dysfunction (ED) and later expanded its use to Pulmonary Arterial Hypertension (PAH).
Since its FDA approval in 1998, Sildenafil has helped millions of men or Assigned Males at Birth (AMABs) rediscover their sexual confidence while also improving cardiovascular outcomes for PAH patients.
However, this small blue pill is more than just appealing. From its fascinating origin as a heart medication to its role in men’s health, understanding the working, advantages, risks, and usage of the medication is essential.
Whether you’re considering the pill for performance enhancement or to treat a serious heart-lung issue, this article provides a detailed overview of every aspect of Sildenafil.
Sildenafil uses and its working
Sildenafil is a versatile medicine that is utilized to address two different conditions: Erectile Dysfunction (ED) in males and Pulmonary Arterial Hypertension (PAH) in both men and women or Assigned Females at Birth (AFABs).
It is marketed under the name Viagra for ED and Revatio for PAH. It is a Phosphodiesterase Type (PDE5) inhibitor that relaxes the blood arteries, allowing easier blood flow.
In the context of ED, when a man is sexually aroused, Nitric Oxide (NO) is produced. It leads to the generation of cyclic Guanosine Monophosphate (cGMP). cGMP is a naturally occurring substance that relaxes the penile smooth muscles and allows for greater blood flow, resulting in an erection.
This little blue pill suppresses the PDE5 enzyme, which normally breaks down cGMP; thereby prolonging the activity of cGMP and enabling an erection when sexual stimulation occurs.
For PAH, the medicine similarly acts by inhibiting PDE5, but in PAH, it relaxes smooth muscles within the blood arteries of the lungs. This, in turn, lowers blood pressure in the lungs and relieves the strain on the heart. By doing so, the medicine enhances exercise capacity and general well-being in people with PAH.
Sildenafil dosage
Sildenafil dose and administration vary significantly depending on the condition being treated. For ED, the normal beginning dose is 50 mg, given orally as needed about 30-60 minutes before sexual activity, with effect lasting up to 4 hours.
This dose can be decreased to 25 mg or raised to a maximum of 100 mg, depending on individual efficacy and tolerance, and it should not be taken more than once per day.
The standard adult dose of the medicine for PAH is 20 mg, given three times daily, with doses spaced around 4 to 6 hours apart. In certain circumstances, and under doctor supervision, PAH dosages can be increased to 80 mg three times a day.
How to take the pill?
Take Sildenafil only as prescribed by your doctor for effective and safe usage. Some general instructions include:
- Consume the pill whole with water. Never crush, chew, or break the pill.
- It can be taken with or without meals; however, a high-fat meal may cause it to take longer to take effect.
- Take it on an empty stomach for better absorption.
- Always adhere to your doctor’s prescribed dosage and frequency.
Side effects of Sildenafil
Although the medicine is well-tolerated, it can lead to some potential side effects, most of which are mild and temporary. These side effects often vanish as your body adjusts to the medication. Commonly reported side effects of the pill are:
- Headache
- Flushing (a sensation of warmth on the face and neck)
- Nausea
- Vomiting
- Dizziness
- Indigestion
In rare cases, the medicine can lead to severe side effects, such as prolonged, painful erections (Priapism), sudden hearing and vision loss, and cardiovascular issues.
Contraindications and warnings
The following contraindications and warnings should be kept in mind while taking this pill:
- The medicine is not appropriate for everyone. It is strictly contraindicated in patients with a history of stroke, heart attack, or serious heart problems.
- Patients with blood cell disorders, including Sickle Cell Anemia or Leukemia, and severe kidney or liver issues.
- Do not take the tablet if you are allergic to Sildenafil or any of its ingredients
- Also, avoid taking the tablet if you have a physical deformity of the penis (for example, Peyronie’s disease), stomach ulcers or bleeding problems, or Low Blood Pressure.
- Do not take the pill if you are using Nitrates to treat chest discomfort or heart problems. This combination might result in a hazardous and sudden decrease in blood pressure.
- Avoid mixing the pill with any other PAH medicines, such as Riociguat or other ED medicines, including Vardenafil and Tadalafil
- Avoid having alcohol and grapefruit or its juice while taking the pill, as it can cause severe adverse reactions.
Conclusion
Sildenafil has gained popularity for treating Erectile Dysfunction and Pulmonary Arterial Hypertension, giving millions of people across the world hope, confidence, and a standard way of living.
Its ability to enhance blood supply, whether in the lungs or the penis, makes it one of the most significant medicinal advances of recent decades.
However, besides being effective, the medication can lead to some side effects, like headaches, and may interact with other medicines, including Nitrates. Thus, while it may appear to be a quick fix, its safe and effective usage necessitates medical supervision, knowledge of possible interactions, and a full understanding of one’s overall health.
Sildenafil is not a miracle pill; rather, it is an effective therapy that works best when supported with a healthy lifestyle and informed use.
