Intravaginal naproxen in preterm labour: a preliminary study
1Akdeniz University, School of Medicine, Department of Obsterics and Gynaecology, Antalya, Turkey.
Summary
Local inhibition of prostaglandin formation using intravaginal naproxen sodium effectively prolonged pregnancy in most patients experiencing preterm labor. This preliminary study found no adverse effects in mothers or fetuses, suggesting a potential new treatment for preterm birth.
Area of Science:
- Obstetrics and Gynecology
- Pharmacology
- Reproductive Medicine
Background:
- Preterm labor is a significant cause of neonatal morbidity and mortality.
- Prostaglandins play a key role in initiating and maintaining labor.
- Current treatments for preterm labor have limitations and potential side effects.
Purpose of the Study:
- To investigate the efficacy of local prostaglandin inhibition in managing preterm labor.
- To evaluate the use of intravaginal naproxen sodium as a tocolytic agent.
Main Methods:
- A preliminary study involving seven patients with preterm labor (27-34 weeks gestation).
- Administration of 500 mg of intravaginal naproxen sodium.
- Inclusion of a triplet pregnancy case refractory to beta-sympathomimetic therapy.
Main Results:
- Pregnancy was prolonged by over 6 days in five out of seven patients.
- No significant maternal or fetal side effects were observed during the treatment period.
Conclusions:
- Intravaginal naproxen sodium demonstrates potential as a safe and effective method to inhibit preterm labor.
- Local prostaglandin inhibition may offer a promising therapeutic approach for prolonging pregnancy.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Intrauterine Drug Delivery Systems
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...
