Abstract

Presently available long-acting reversible female contraceptive implants are said to be an effective way of preventing unintended pregnancy. Unacceptable side effects attributed by these contraceptive implants act as a major drawback for the practitioners. These problems pave the way for the development of a new form of long acting non-hormonal female contraceptive implant, especially in the developing countries. PCL-DA: PEG-DA polymeric scaffold is grafted with Styrene Maleic Anhydride (SMA) based hydrogel, and their physicochemical, thermal and biological parameters are being explored for developing a bio-degradable form of the non-hormonal intrauterine contraceptive implant. With the fixed ratio of PEG-DA: PCL-DA polymer, SMA hydrogel was added at four different concentrations to determine the optimum concentration of SMA hydrogel for the development of a promising long-acting biodegradable intrauterine contraceptive implant. Structural elucidation of the polymers was confirmed using H-1 and C-13 NMR spectroscopic analyses. The physiochemical characterization report suggests that SMA hydrogel interacts with the PCL-DA: PEG-DA polymeric scaffold through intermolecular hydrogen bonding interaction. The in-vitro spermicidal activity of the polymeric scaffold increases when the concentration of SMA based hydrogel in the polymer samples is increased without showing any significant toxicological effects. From the study results, it may be concluded that SMA hydrogel grafted PCL-DA: PEG-DA scaffold can be developed as intra-uterine biodegradable non-hormonal female contraceptive implant due to its excellent bio-compatibility and spermicidal activity.
