Drug delivery to delay delivery

Preterm birth, often caused by inflammation, is a major contributor to infant morbidity and mortality. It often cannot be predicted, but even for women who are known to be at risk of preterm delivery, there is no currently approved intervention to prevent it, although progesterone-based interventions are sometimes attempted. To improve access of treatments to the appropriate tissues for preventing preterm delivery, Zierden et al. designed a mucoinert nanosuspension to optimize vaginal dosing of therapeutics. The authors demonstrated the effectiveness of their approach in mouse models using histone deacetylase inhibitors with and without progesterone. Their approach improved the rates of full-term delivery of neurotypical pups.
