Vardenafil
The chemical formula for Vardenafil is C23H32N6O4S, and it typically lasts 4 to 6 hours in the human body. Vardenafil is primarily marketed under the brand names Levitra 20 mg (Bayer Pharmaceuticals) and Vilitra (Centurion Laboratories).
How do ED Pills Work?
The Role of Nitric Oxide: When a man is sexually aroused, the brain signals the release of nitric oxide in the penis. This chemical relaxes the smooth muscles in the penile tissue, allowing blood to flow into the spongy chambers (corpora cavernosa and corpus spongiosum), leading to an erection.
The Role of PDE5 Inhibitors: In some men, an enzyme called phosphodiesterase type 5 (PDE5) breaks down cGMP too quickly, preventing sufficient blood flow to the penis. ED pills inhibit the function of PDE5, allowing cGMP to remain active longer. This results in improved blood flow and helps maintain an erection during sexual stimulation.
Common Misconceptions About ED Pills: There are many misconceptions about the effectiveness of these medications. Here is a list of them:
Sexual Stimulation is Not Required: Erection pills do not cause spontaneous erections; sexual arousal is necessary for them to work.
Timing: These medications are typically taken before sexual activity. The onset of action varies; some may work within 15 minutes, while others might take up to an hour.
Consultation is Necessary: Always consult a healthcare provider before using ED pills, especially if you have underlying health conditions or take other medications.

When are ED Pills Not Safe?
Nitrate Medicines: These medicines are commonly prescribed for chest pain (also called angina). People who are taking nitrates like Isosorbide Dinitrate (Isordil) or Nitroglycerin (Nitrostat) should avoid these pills. The combination of these two medications is dangerous and can cause severe hypotension (low blood pressure).
Alpha-blockers: These medications are typically prescribed to treat an enlarged prostate or male pattern baldness. Examples include Doxazosin (Cardura) and Dutasteride (Avodart, Jalyn).
CYP3A4 Enzyme Blocking Medicines: Some medications, such as ritonavir, can slow the breakdown of ED drugs like Viagra, leading to increased levels in the body and a higher risk of side effects. Other CYP3A4 inhibitors include Itraconazole (Sporanox, Tolsura) and Ketoconazole (Extina, Ketozole).
Hypotension, or very low blood pressure.
Hypertension, or uncontrolled high blood pressure.
Severe liver disease or kidney disease that requires dialysis.
Recent heart or blood vessel problems (within the past six months), including heart attacks, strokes, or life-threatening arrhythmias
Eye diseases such as non-arteritic anterior ischemic optic neuropathy (NAION) or retinitis pigmentosa
Allergies to ED pills
How to Buy ED Pills Online?
Obtain a Prescription: In the USA, Sildenafil, Avanafil, Tadalafil, and Vardenafil require a doctor’s prescription. Some reputable online pharmacies offer telehealth consultations, allowing licensed healthcare professionals to assess your condition and prescribe medication if appropriate.
Choose a Reputable Pharmacy: Avoid those online pharmacies that do not list their phone numbers or physical addresses. Avoid websites offering ED pills without a prescription or at suspiciously low prices, as they may sell counterfeit drugs.
Verify Legitimacy: In the United States, you can check the legitimacy of online pharmacies through the National Association of Boards of Pharmacy.
