π Zenegra 100mg (Sildenafil Citrate)
π©Ί Product Description
Zenegra 100mg is a prescription medication used to treat Erectile Dysfunction (ED), which is the inability to achieve or maintain an erection sufficient for sexual activity.1 It is also sometimes used off-label to treat pulmonary arterial hypertension (high blood pressure in the arteries of the lungs).2
The active ingredient is Sildenafil Citrate, which belongs to a class of drugs called Phosphodiesterase Type 5 (PDE5) Inhibitors.3
Sildenafil works by selectively inhibiting the PDE5 enzyme, which is abundant in the corpus cavernosum (spongy tissue) of the penis.4 Inhibition of this enzyme leads to:
-
Increased cGMP: The levels of cyclic Guanosine Monophosphate (5$\text{cGMP}$) increase.6 $\text{cGMP}$ is responsible for relaxing the smooth muscles in the penile blood vessel walls.7
-
Increased Blood Flow: Muscle relaxation allows for a greater inflow of blood into the penis, resulting in an erection when accompanied by sexual stimulation. The drug does not cause a spontaneous erection without arousal.8
The 100mg strength is the maximum recommended dose and is typically used when lower doses (like 50mg) have not achieved the desired response.
Key Benefits:
-
Treats Erectile Dysfunction: Enables a man to achieve and maintain an erection suitable for intercourse.9
-
Rapid Onset: Usually takes effect within 30 to 60 minutes.
-
Effective Response: Provides a reliable solution for many men with ED.
β οΈ Critical Precautions
Due to the potent effects of Sildenafil on the cardiovascular system, strict adherence to medical advice is essential.
Please inform your doctor if the patient:
-
Uses Nitrates: ABSOLUTE CONTRAINDICATION: Never take Zenegra (Sildenafil) with any form of nitrate medication (e.g., nitroglycerin, isosorbide mononitrate, isosorbide dinitrate) used for chest pain. The combination can cause a sudden, severe, and potentially fatal drop in blood pressure.10
-
Uses Alpha-Blockers: Taking Sildenafil with alpha-blockers (used for hypertension or enlarged prostate) can significantly lower blood pressure.
-
Has Severe Heart or Blood Pressure Problems: Such as recent stroke, recent heart attack, life-threatening arrhythmia, or severe hypotension (low blood pressure).11
-
Has Priapism Risk: Has conditions like sickle cell anemia, multiple myeloma, or leukemia, which increase the risk of priapism (a painful erection lasting more than 4 hours).
-
Has Severe Liver or Kidney Disease: Dose adjustments may be necessary.
-
Has Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION): A condition leading to sudden vision loss.12
π Side Effects
Most side effects are generally mild and temporary.
Common Side Effects include:
-
Headache: The most common side effect due to vasodilation.
-
Flushing: Redness and warmth in the face.13
-
Dyspepsia: Indigestion or heartburn.14
-
Nasal Congestion (stuffy nose).15
-
Visual Disturbances: Mild and transient changes in vision, such as a blue-tinge to vision or increased light sensitivity.16
Serious Side Effects (Seek medical attention immediately):
-
Priapism: A painful erection lasting longer than 4 hours. Seek emergency medical help immediately.
-
Sudden Vision Loss: In one or both eyes.17
-
Sudden Hearing Loss or Tinnitus (ringing in the ears).18
