Transdermal nitroglycerin (TNG) patches are more effective than isosorbide dinitrate (ISD) tablets in delaying preterm labor. Both treatments showed similar side effect rates, but TNG offered superior labor delay for pregnant women.
Area of Science:
- Obstetrics and Gynecology
- Pharmacology
- Neonatal Medicine
Background:
- Preterm labor is a leading cause of pregnancy hospitalization.
- It can result in severe complications for newborns.
- Effective interventions are crucial for improving neonatal outcomes.
Purpose of the Study:
- To compare transdermal nitroglycerin (TNG) patches and sublingual isosorbide dinitrate (ISD) tablets.
- To evaluate their efficacy in preventing preterm delivery.
- To assess side effect profiles of both medications.
Main Methods:
- A single-blinded clinical trial involving 110 pregnant women (24-34 weeks gestation).
- Randomized groups received either TNG patches or ISD tablets.
- Exclusion criteria included complications like hypotension or headache post-medication.
Main Results:
- 58 patients completed the study (29 per group).
- Transdermal nitroglycerin (TNG) significantly delayed preterm labor and improved recovery time compared to isosorbide dinitrate (ISD).
- No significant differences in complications or contraction frequency were observed between groups.
Conclusions:
- Transdermal nitroglycerin (TNG) is more effective than isosorbide dinitrate (ISD) for delaying preterm labor.
- Both medications appear to have comparable rates of side effects.
- TNG demonstrates a clinical advantage in managing preterm labor.

Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
