An estriol-eluting pessary to treat pelvic organ prolapse
Abstract Pelvic organ prolapse affects up to 50% of parous women. Commonly used treatment options have unwelcome attributes; pessaries can cause erosion and estrogen creams need to be applied frequently, which is inconvenient and difficult to administer.

description | Abstract Pelvic organ prolapse affects up to 50% of parous women. Commonly used treatment options have unwelcome attributes; pessaries can cause erosion and estrogen creams need to be applied frequently, which is inconvenient and difficult to administer. This study involved the development of an estriol-releasing pessary utilising 3D printing molds. We incorporated varying amounts of estriol (1%, 10% and 15%) into the silicone pessary. We optimised the mechanical aspects of the pessary so it had a similar strength to commercially available pessaries. We investigated estriol release from the pessary over 3 months. We explored possible interactions between the drug and polymers via FTIR. The MED-4870 silicone ring with similar mechanical strength to pessaries currently used to treat pelvic organ prolapse. The medical pessaries present a sustained release in simulated vaginal fluid over 3 months. The pessary with 10% estriol delivered the optimal dose at 0.8 mg each week. Mechanical strength of this pessary showed no difference after emersion in simulated vaginal fluid for 3-month, supporting the long-term application. An estriol-loaded pessary was successfully developed to treat pelvic organ prolapse with sustained release of estriol over 3 months. This pessary provides promising potential to treat pelvic organ prolapse and vaginal atrophy. |
