produced in the erectile tissue of the penis, which activates an enzyme called guanylate cyclase. This enzyme, in turn, increases levels of cyclic guanosine monophosphate (cGMP), leading to the relaxation of smooth muscles in the blood vessels of the penis. As a result, blood flow to the penile tissue increases, enabling an erection.

Interaction with the enzyme PDE5

Nizagara 100 works by inhibiting the action of phosphodiesterase type 5 (PDE5), an enzyme that breaks down cGMP. By inhibiting PDE5, Nizagara helps to maintain higher levels of cGMP in the penis, prolonging the vasodilatory effects and promoting stronger erections.

Effects on Blood Flow

Dilating blood vessels

By blocking PDE5, Nizagara facilitates the dilation of blood vessels in the penis, allowing for increased blood flow to the erectile tissue. This enhanced blood flow is essential for achieving and sustaining an erection.

Increased blood flow to the penis

The increased blood flow induced by Nizagara results in improved erectile function, enabling men with ED to achieve satisfactory sexual performance. It is important to note that sexual stimulation is still required for Nizagara to be effective.

Duration of Action

Nizagara typically begins to take effect within 30 to 60 minutes after ingestion. The duration of its action can vary from person to person but generally lasts for about four to six hours. It is important to follow the prescribed dosage and not exceed the recommended daily intake.

Dosage and Administration

Recommended dosage

The recommended starting dose of Nizagara is usually 50 mg, taken approximately one hour before sexual activity. Depending on individual response and tolerability, the dose may be adjusted to 100 mg or reduced to 25 mg. It is essential to consult a healthcare professional for personalized dosing recommendations.

Administration guidelines

Nizagara should be taken orally with a full glass of water. It can be taken with or without food, although consuming a heavy meal before taking Nizagara may delay its onset of action. It is important not to crush, chew, or break the tablets, as this may affect their efficacy.

Side Effects

Common side effects

Like all medications, Nizagara may cause side effects in some individuals. Common side effects may include headache, facial flushing, indigestion, nasal congestion, dizziness, and blurred vision. These side effects are usually mild and transient.

Rare but serious side effects

In rare cases, Nizagara may cause more severe side effects such as priapism (prolonged erection lasting more than four hours), sudden hearing loss, and vision changes. If any of these symptoms occur, it is crucial to seek medical attention immediately.

Nizagara is contraindicated in individuals who are allergic to sildenafil or any of the other ingredients in the medication. It should not be taken concurrently with nitrates or nitric oxide donors, as this can lead to a dangerous drop in blood pressure.

It is important to discuss any pre-existing health conditions with a healthcare provider before starting treatment.

Comparison with Similar Medications

Comparison with other ED medications

Nizagara shares similar mechanisms of action and efficacy with other PDE5 inhibitors such as Viagra (sildenafil), Cialis (tadalafil), and Levitra (vardenafil).
