What is Vasafil?
Vasafil is a brand name for a medication containing the active ingredient sildenafil citrate. It belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Sildenafil is a well-established and widely used drug for treating male erectile dysfunction (ED). Vasafil is available in tablet form and is a prescription-only medication.
Primary Medical Uses of Vasafil
The primary and officially indicated use for Vasafil is the treatment of erectile dysfunction, commonly known as impotence. This condition is defined as the inability to achieve or maintain a hard, erect penis suitable for sexual activity.
How Vasafil Treats Erectile Dysfunction
When sexual stimulation occurs, the body releases nitric oxide (NO). This chemical then activates an enzyme that produces cyclic guanosine monophosphate (cGMP), which is responsible for relaxing the smooth muscles of the penis, allowing for increased blood flow.
Vasafil works by inhibiting the PDE5 enzyme, which is responsible for breaking down cGMP. By blocking this enzyme, Vasafil effectively prolongs the action of cGMP, causing the smooth muscles in the penis to relax and remain relaxed for longer. This increased and sustained blood flow is what facilitates a stronger and more lasting erection. It is important to note that Vasafil does not increase sexual desire and requires sexual excitement to be effective.
Vasafil vs. Other Sildenafil Products
While Vasafil is one brand of sildenafil, it's not the only one. The most widely known brand is Viagra, which also uses sildenafil for ED. Another brand, Revatio, also contains sildenafil but is used for a completely different condition: pulmonary arterial hypertension (PAH). The distinction is crucial, as the dosages and indications differ significantly. Vasafil is not indicated for use in women.

Common and Serious Side Effects
Like any medication, Vasafil can cause side effects. It is vital to be aware of these and contact a healthcare provider if they are persistent or severe.
Common Side Effects
- Headache
- Flushing or hot flushes
- Indigestion or heartburn
- Nasal congestion
- Dizziness
- Mild visual changes, like blurred vision
Serious Side Effects (Seek Immediate Medical Attention)
- Priapism: A painful erection that lasts for more than four hours. If untreated, this can cause permanent damage.
- Sudden Vision Loss: Non-arteritic anterior ischemic optic neuropathy (NAION), which can lead to decreased or permanent vision loss.
- Sudden Hearing Loss: A rapid decrease or loss of hearing, sometimes accompanied by tinnitus and dizziness.
- Allergic Reaction: Swelling of the face, lips, tongue, or difficulty breathing.
Drug Interactions and Contraindications
Several key drug interactions and contraindications make Vasafil unsuitable for some individuals. A thorough medical evaluation is essential before starting treatment.
- Nitrates: Vasafil must not be taken with nitrate medications (such as nitroglycerin), as the combination can cause a sudden and severe drop in blood pressure, which may be life-threatening.
- Guanylate Cyclase Stimulators: Use with riociguat (Adempas), a drug for PAH, is also contraindicated due to the risk of symptomatic hypotension.
- Alpha-Blockers: Coadministration with alpha-blockers, used for high blood pressure or prostate issues, should be approached with caution due to the risk of symptomatic low blood pressure.
- Certain Antibiotics and Antifungals: Medications like erythromycin, ketoconazole, and itraconazole can increase sildenafil levels in the blood, potentially increasing the risk of side effects.
Conclusion
Vasafil, a brand of sildenafil, is an effective and safe treatment for erectile dysfunction when used correctly and under medical supervision. It works by enhancing the body's natural response to sexual arousal by improving blood flow to the penis. However, it is a prescription medication that requires careful consideration of its potential side effects and serious interactions with other drugs, particularly nitrates. Patients should always consult a doctor to determine if Vasafil is the right treatment and to receive the appropriate instructions.
