RESUMO
The speedy change in the Saudi Arabian community's socio-demographic pattern will significantly influence reproductive attitudes and practices with increasing preferences toward family planning because of the use of contraceptives. The current study was conducted to determine the attitudes and knowledge of married women in the Aseer region of Saudi Arabia regarding contraceptives use. Saudi married women from the Aseer region were the participants of this cross-sectional study. The study's objectives were covered via a standardized questionnaire, and the study comprised of 412 married women. A 100 % participant's response was demonstrated, while 31.8 % of the respondents were 31-40 years old. Most of the participants have a great awareness and knowledge about contraceptives, while (n=324; 78.6%) had previously used contraceptives. Additionally, 297 (72.1%) have intention to use contraceptive methods in the future. Majority of the participants (n=297; 91.6%) considered the economic and family planning as a reason for using the contraceptives, while natural family planning was mostly preferred (n=202; 49%). Logistic regression analysis exhibited significant correlation between the age, education, employment, monthly income and children number. The findings show that Saudi married women have high perceptions and knowledge of contraception. However, more effort is required to raise awareness regarding family planning and contraceptives, whereas the policy makers must exclude the obstacles to women from using contraceptives.

Background: Tocopherol acetate (TA) is known as a skin moisturizing and photoprotective agent. One major drawback with tocopherol and its derivatives remains its limited stability. Aim: To develop highly stable TA-containing ethosomal gel (TAEG) as an advanced dosage form. Methods: A cold method technique was used to produce the ethosomes. An in vitro evaluation of viscosity, conductivity, and pH stability was carried out for three months. An in vitro physical characterization of the nanoparticles (NPs) that included particle size (PS), zeta potential (ZP), transmission electron microscopy (TEM), and Fourier-transform infrared (FTIR) spectroscopy analysis was then performed. Organoleptic evaluation, thermostability at 8 °C, 25 °C, 40 °C and 40 °C ± 75% RH, pH, conductivity, viscosity, and spreadability measurements were also performed in vitro for three months. An ex vivo permeation study was performed in phosphate-buffered solution (1× PBS; pH 5.5 or pH 7.4) at 37 ± 0.2 °C by using rat abdominal skin and the Franz diffusion cell method. The data of three independent experiments were expressed as mean ± SD. A two-way ANOVA was applied to compare data on TAEG versus TA control gel (TACG). Results: PS of the ethosomes was in the range of 144−289 nm. A total of nine formulations were developed. Optimized TAEG formulation (TA-5) was selected based on the highest entrapment efficiency (EE) of 99.71%, while the stability, the PS, and the uniformity-based polydispersity index (PDI) were also among the best. TA-5 exhibited smooth spherical ethosomal NPs with PS of 200.6 nm, ZP value of −18.6 V, and PDI of 0.465. Stability data obtained for TA-5 in terms of rheology, conductivity, and pH presented no significant change (p > 0.05) during the entire study duration. Rheological studies indicated that TA-5 followed a non-Newtonian behavior of shear thinning system. The ex vivo drug permeation was 44.55 ± 0.01% in TA-5 and the drug retention in skin was 51.20%, which was significantly higher than TACG as observed after 24 h permeation study (p < 0.05). Conclusions: The newly developed TAEG formulation appears promising to enhance the effectivity of TA and its topical application.
