8. Future perspective
As a result, the solid SNEDDS, which converts the crystalline form of the drug to its amorphous form via an o/w nanoemulsion, could be recommended for enhancing the oral bioavailability of sildenafil in this research. In addition, further experiments should be performed, including dissolution-equivalent study on various pHs, stability study and pharmacokinetic investigation in larger animal models, prior to carry out clinical research.

Methods: We administered a single daily dose of 0.5 milligrams per kilogram of sildenafil for 3 months to 10 patients with pulmonary arterial hypertension. Their average age was 26.8 years. Diagnoses were primary pulmonary arterial hypertension in 3 patients, and secondary pulmonary arterial hypertension due to congenital cardiac disease in the remaining 7 patients. Outcome measures included the clinical state, the mean pulmonary arterial pressure, and the indexed pulmonary vascular resistance; the latter two assessed at the beginning and at the end of the treatment period by cardiac catheterization.
| Parameter | Value | Description | Notes |
|---|---|---|---|
| Absorption time | 30-60 minutes | Time to reach peak plasma levels | Faster onset compared to tablets |
| Peak plasma concentration | 150-200 ng/mL | Max systemic concentration | Varies per dose and individual |
| Half-life | 4-5 hours | Time to reduce concentration by half | Helps determine dosing intervals |
| Bioavailability | 40-50% | Fraction reaching systemic circulation | Slightly variable across patients |
We also analysed the cost of the treatment.

The mean cost per patient for 3 months on oral treatment with sildenafil was 120.99 American dollars. Conclusions: A low dose of 0.5 milligrams per kilogram per day of oral sildenafil, instead of 1 to 4 milligrams per kilogram per day, provided early clinical and haemodynamic improvements, and proved less expensive.
- The cost of sildenafil oral solution varies depending on brand and pharmacy.
- Generic versions are typically less expensive.
- Availability might be limited in some regions or countries.
Additional experience is now required to define more reliably the true long-term benefits of this therapy.
