Cytofluorimetric analysis showed that sildenafil significantly increased NO production in basal condition.

We have retrospectively reviewed 14 children with vascular anomalies treated with sildenafil.

Moreover, sildenafil treated mice showed a pattern of behaviors reflecting lower anxiety.

In addition, animals treated with sildenafil after HI insult demonstrated improved functional recovery.

There was, however, no difference in effect between the two doses of sildenafil.

All patients were subsequently commenced on oral sildenafil 50 mg t.d.s.

The onset of erectile activity was faster with mirodenafil than with sildenafil citrate.

Importantly, sildenafil therapy did not alter any of these parameters in nonischemic limbs.

Studies in men have documented positive effects of concomitant treatment with sildenafil or tadalafil.

This observation should shed some lights towards application of sildenafil in energy-related cardiovascular diseases.

Further observation should be necessary for the patient including new medicine, such as sildenafil citrate.

Pending more convincing prospective data, we recommend caution prior to sildenafil use for vascular anomalies.

He was treated with sildenafil for 12 months, with complete resolution of pulmonary arterial hypertension.

The objective of this study was to investigate if sildenafil influences the pharmacokinetics of nelfinavir.

The present findings demonstrated that sildenafil has therapeutic potential for cognitive deficit associated with multiple sclerosis.
