What Is Sildenafil Citrate?
Sildenafil citrate is a medication that is commonly used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). It belongs to a class of drugs known as PDE5 or phosphodiesterase type 5 inhibitors. Sildenafil 25mg tablet works by improving blood flow to the penis, which helps men to get or maintain an erection. In the case of pulmonary arterial hypertension, Sildenafil works by dilating the blood vessels in the lungs, reducing the workload on the heart, and improving exercise capacity.
Proper Dosage & Storage
Sildenafil citrate is available in different strengths:
- Sildenafil 25 mg: It is typically the starting dose for older individuals or individuals with underlying health conditions.
- Sildenafil 50 mg: An individual’s response to a lower dose may determine a moderate dose.
- Sildenafil 100 mg: In general, individuals who require a stronger effect are prescribed this dose. You should not exceed this dosage without consulting your healthcare provider.
Important Dosage Considerations
- Take as Needed: Sildenafil citrate 25mg for erectile dysfunction is often taken as needed, approximately 30 minutes to 1 hour before sexual activity.
- Once Daily: In some cases, a healthcare provider may prescribe a daily dose for continuous treatment.
- Avoid Alcohol and High-Fat Meals: Alcohol and high-fat meals can affect the absorption and effectiveness of Sildenafil. It’s often recommended to avoid these around the time of taking the medication.
How to Store?
- Store sildenafil at room temperature, away from moisture and heat.
- Keep the medication in its original packaging to protect it from light and moisture.
- Store sildenafil in a location that is inaccessible to children and pets.
- Do not use Sildenafil past its expiration date.
Always follow your healthcare provider’s instructions regarding dosage, storage, and Sildenafil 25mg price. Consult with them if you have any questions or concerns.
How Does Sildenafil Work?
Here are the steps of Sildenafil citrate 25mg treating erectile dysfunction in men:
Step 1. Release of Nitric Oxide (NO): Sexual stimulation leads to the release of nitric oxide (NO) from nerve endings in the erectile tissue of the penis.
Step 2. Activation of Guanylate Cyclase: Nitric oxide activates the enzyme guanylate cyclase, which results in an increased production of cyclic guanosine monophosphate (cGMP) from guanosine triphosphate (GTP).
Step 3. cGMP Relaxation Effect: Increased levels of cGMP cause the smooth muscles in the erectile tissue of the penis to relax.
Step 4. Dilation of Blood Vessels: The relaxation of smooth muscles allows the blood vessels in the penis to dilate, leading to increased blood flow.
Step 5. Increased Blood Flow to Corpus Cavernosum: The enhanced blood flow fills the spongy tissue of the corpus cavernosum in the penis, leading to an erection.
Step 6. PDE5 Inhibition by Sildenafil: Sildenafil inhibits the enzyme phosphodiesterase type 5 (PDE5), which is responsible for breaking down cGMP.
Step 7. Prolonged Action of cGMP: By inhibiting PDE5, Sildenafil prevents the rapid degradation of cGMP, allowing it to accumulate and exert a more prolonged vasodilatory effect.
Step 8. Sustained Erection: The sustained presence of cGMP maintains the relaxation of smooth muscles and the dilation of blood vessels, helping to sustain the erection during sexual activity.
Warnings and Precautions
- Exercise caution in individuals with a history of heart disease or stroke.
- Be mindful of potential decreased blood pressure, particularly when used concurrently with nitrate medications.
- Rare reports of cardiac events emphasize the importance of careful evaluation, especially in patients with cardiovascular concerns.
Priapism: It is a medical condition characterized by a persistent and often painful erection lasting more than four hours, unrelated to sexual arousal or stimulation. Consider the precautions like:
- Emphasize the need for immediate medical attention to prevent potential tissue damage.
- Consider adjusting the dosage, especially for individuals at a higher risk of priapism.
