Outcome Measures

Primary Outcomes (1)

  • the proportion of women remaining undelivered during the whole period of hospitalization. Treatment failure is considered in participants who delivered during this period, or those who need repeated treatment course.

    9 months

Secondary Outcomes (4)

  • readmission after discharge

    9 months

  • time (days) till delivery

    9 months

  • maternal outcomes (gestational age at delivery, mode of delivery, any complications during delivery)

    9 months

  • neonatal outcomes (weight, Apgar score, admission to neonatal intensive care unit

    9 months

Study Arms (2)

nifedipen and sildenafil

ACTIVE COMPARATOR

The protocol for nifedipen in our units consists of 20 mg orally stat, followed by 10 mg orally every 6-8 hours, at the same time sildenafil citrate will be administered vaginally in a dose of 25mg at 8 hourly intervals and both medications will be continued for 48-72 hours as indicated.

Drug: nifedipenDrug: Sildenafil

nifedipen only

ACTIVE COMPARATOR

nifedipine alone in the same regimen and duration described before.

Drug: nifedipen

Eligibility Criteria

Sexfemale
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Pregnant patients presented in outpatient clinic, admitted through emergency room or referred from any other hospitals will be the candidates for the study if they are of any age, any parity, carrying a singleton pregnancy, at a gestational age (GA) between 24 and 34 weeks, and whether or not they had a previous history of PTL.

You may not qualify if:

  • The presence of major fetal anomaly, intrauterine fetal death, advanced cervical dilatation (\>4cm), membranes bulging into the vagina in asymptomatic women, history of ruptured membranes, major antepartum hemorrhage, major chronic medical disorder (such as chronic hypertension, chronic renal disease, and pre-gestational diabetes mellitus as these conditions would increase the risk of PTL and potentially confound the primary study outcome), twins or higher order multiple pregnancy, any other condition in which continuation of the pregnancy can harm the mother or fetus and any contraindication for nifedipin and/or nicorandil therapy.
