Mode of Action

The rigid hygroscopic rod absorbs fluids in the uterine cervical canal, gradually increases its volume and dilates the cervix.

After 4 to 6 hours, the 3 mm rod will have expanded to 8.3–10 mm and the 4 mm rod up to 10–12.5 mm.

Simultaneously, Dilapan-S initiates endogenous prostaglandin release causing collagen degradation and ripening of the cervix.

Patented hydrogel AQUACRYL guarantees consistency and predictability of action. It contains no pharmaceutically active substances that would be released during its application.
