Product Description

DP Viagra by Dragon Pharma is a high-quality oral medication formulated with Sildenafil Citrate, the established and extensively studied active ingredient for the treatment of erectile dysfunction (ED). Each tablet delivers a precise 50 mg dose of sildenafil citrate, the dosage recommended for most patients as the starting point for effective erectile function support.

Sildenafil citrate is a selective phosphodiesterase-5 (PDE5) inhibitor. The physiological mechanism of penile erection involves the release of nitric oxide (NO) in the corpus cavernosum during sexual stimulation. Nitric oxide activates the enzyme guanylate cyclase, which increases levels of cyclic guanosine monophosphate (cGMP). This produces smooth muscle relaxation in the corpus cavernosum, allowing blood inflow. Sildenafil enhances this natural process by inhibiting PDE5, the enzyme responsible for the degradation of cGMP. When sexual stimulation triggers local NO release, PDE5 inhibition by sildenafil results in elevated cGMP levels, leading to smooth muscle relaxation and increased blood flow to the corpus cavernosum. It is important to note that sildenafil has no effect in the absence of sexual stimulation.

The clinical efficacy of sildenafil citrate is well-documented. Sildenafil has demonstrated statistically significant improvement compared to placebo across numerous clinical studies, with improvements in success rates for sexual intercourse. Significantly improved erectile function has been demonstrated for sildenafil compared with placebo across all efficacy parameters analyzed, regardless of patient age, race, body mass index, ED etiology, ED severity, ED duration, or the presence of various comorbidities. Sildenafil is an effective oral treatment in men with erectile dysfunction and has been shown to be significantly superior to placebo in improving erections and allowing successful penetrative sexual intercourse.

DP Viagra is manufactured by Dragon Pharma, a producer known for pharmaceutical-grade products. Each tablet contains 50 mg of sildenafil citrate, providing a reliable and consistent dosage for predictable results.

Usage Guidelines

For most patients, the recommended dose is 50 mg taken as needed, approximately one hour before sexual activity. Sildenafil tablets may be taken anywhere from 30 minutes to 4 hours before sexual activity. Based on effectiveness and toleration, the dose may be increased to a maximum recommended dose of 100 mg or decreased to 25 mg. The maximum recommended dosing frequency is once per day. DP Viagra is dosed at 3 tablets per week, providing a structured regimen for consistent support.

Safety Information and Contraindications

Sildenafil citrate is contraindicated in patients using nitric oxide donors, such as organic nitrates or organic nitrites in any form, as sildenafil potentiates the hypotensive effects of nitrates. Patients should not use sildenafil citrate if sexual activity is inadvisable due to cardiovascular status.

Use sildenafil citrate with caution in patients with anatomical deformation of the penis, such as cavernosal fibrosis or Peyronie’s disease, or in patients with conditions predisposing them to priapism. Patients should seek emergency treatment if an erection lasts more than 4 hours.

Sildenafil is cleared predominantly by the CYP3A4 hepatic microsomal isoenzyme. Patients should inform their healthcare provider of all medications they are taking, particularly nitrates, alpha-blockers, and other PDE5 inhibitors.

Top 10 Frequently Asked Questions

1. What is DP Viagra and how does it work?

DP Viagra contains sildenafil citrate, a phosphodiesterase-5 (PDE5) inhibitor indicated for the treatment of erectile dysfunction. It works by inhibiting the PDE5 enzyme, which is responsible for the breakdown of cGMP in the corpus cavernosum. This allows increased blood flow to the penis during sexual stimulation, facilitating an erection.

2. What is the recommended dosage for DP Viagra?

The recommended dose for most patients is 50 mg taken as needed, approximately one hour before sexual activity. Sildenafil tablets may be taken anywhere from 30 minutes to 4 hours before sexual activity. Based on effectiveness and toleration, the dose may be adjusted to a maximum of 100 mg or decreased to 25 mg. The maximum recommended dosing frequency is once per day. DP Viagra is dosed at 3 tablets per week.

3. How long does sildenafil citrate stay in the body?

Sildenafil and its active metabolite have terminal half-lives of approximately 4 hours. Sildenafil is excreted as metabolites predominantly in the feces (approximately 80% of the administered oral dose) and to a lesser extent in the urine (approximately 13% of the administered oral dose). The product-listed active half-life of 17.5 hours reflects the overall duration of pharmacodynamic effect.

4. What are the common side effects of sildenafil citrate?

Common side effects may include headache, flushing, indigestion, nasal congestion, dizziness, and visual disturbances such as changes in color vision. The selectivity of sildenafil for PDE5 versus PDE6, an enzyme found in the retina, is thought to be the basis for abnormalities related to color vision observed with higher doses or plasma levels. Patients should consult a healthcare professional for a complete list of potential side effects.

5. Can I take DP Viagra with food?

Sildenafil tablets may be taken with or without food. However, when sildenafil tablets are taken with a high-fat meal, the rate of absorption is reduced, with a mean delay in time to maximum concentration of 60 minutes and a mean reduction in maximum concentration of 29%. For optimal results, it is recommended to take the tablet on an empty stomach or with a light meal.

6. Who should not take sildenafil citrate?

Sildenafil citrate is contraindicated in patients using organic nitrates or nitrites in any form, as it potentiates the hypotensive effects of these medications. Patients should not use sildenafil if sexual activity is inadvisable due to cardiovascular status. Patients with a history of hypersensitivity to sildenafil or any component of the tablet should not use this product.

7. Is sildenafil citrate clinically proven to be effective?

Yes. Sildenafil has demonstrated statistically significant improvement compared to placebo in numerous clinical studies. Significantly improved erectile function was demonstrated for sildenafil compared with placebo for all efficacy parameters analyzed, regardless of patient age, race, body mass index, ED etiology, ED severity, ED duration, or the presence of various comorbidities. Sildenafil was significantly superior to placebo in improving erections and allowing successful penetrative sexual intercourse.

8. How long does it take for DP Viagra to start working?

Following oral administration, sildenafil is rapidly absorbed. Maximum observed plasma concentrations are reached within 30 to 120 minutes (median 60 minutes) of oral dosing in the fasted state. The medication may be taken anywhere from 30 minutes to 4 hours before sexual activity.

9. Can I take DP Viagra with other medications?

Sildenafil should not be taken with organic nitrates or nitric oxide donors. Patients taking alpha-blockers, other PDE5 inhibitors, or medications metabolized by CYP3A4 (such as certain antifungals and antibiotics) should exercise caution and consult a healthcare professional. Always inform your healthcare provider of all medications you are taking.

10. What should I do if I experience an erection lasting more than 4 hours?

Patients should seek emergency medical treatment if an erection lasts more than 4 hours, as this condition (priapism) requires immediate medical attention to prevent permanent damage to the penis. Use sildenafil citrate with caution in patients predisposed to priapism.
