Brief Summary

  • Mild pre-eclampsia represents 75% of cases with pre-eclampsia, possible progression to severe pre-eclampsia makes mild pre-eclampsia a serious problem that requires attention.
  • Previous studies have shown that expectant and conservative management of pre-eclampsia in the context of extreme prematurity may improve perinatal outcomes. Indeed, it has been estimated that for each additional day of pregnancy prolongation between 24 and 32 weeks of gestation, there is a nonlinear corresponding gain of 1% in fetal survival.
  • Sildenafil citrate has been used for increasing utero-placental perfusion in cases with intrauterine growth restriction, which makes it a promising drug in management of mild pre-eclampsia.

Study Arms (2)

Intervention Group

ACTIVE COMPARATOR

• The intervention group will be supplied with Sildenafil Citrate (Respatio® 20mg tablets manufactured by Pharma Right Group , Egypt) according to the patient's weight by the rate of (1.5 mg/kg/day) divided into three doses per day ( every 8 hours) till termination of pregnancy.

Drug: Sildenafil 20 MG

Control Group

PLACEBO COMPARATOR

\- The control group will be supplied with a placebo drug that has the same shape, size and color but without the active ingredient and it would also be taken in a similar way. The placebo tablet will be manufactured at the faculty of pharmacy, Assiut University.

Drug: Placebo Oral Tablet

Interventions

Also known as: Sildenafil Citrate 20 mg ( Respatio® 20 mg)
