ABSTRACT
It is well known that vaccination is the best clinical approach for successfully controlling COVID-19 infection. Understanding the disparities in COVID-19 vaccination apprehension among parents in different societies is crucial for effectively implementing COVID-19 vaccination programs. This observational cross-sectional study was carried out in the Riyadh region of Saudi Arabia between February and April 2022. The validated questionnaire was shared with parents who had children between the ages of five and eleven years. The collected data were analyzed using descriptive and inferential statistical methods. Multinomial regression analysis was conducted to determine the factors significantly affecting vaccine-use decisions. Of the 699 participants, 83% of the mothers were between the ages of 35 and 44 years, 67% were university educated, and only 14% were healthcare workers. A large proportion of parents, with an age range of 18-34 years (p = 0.001), and those with a higher income group (p = 0.014), demonstrated significant vaccine hesitancy. Further, parents who received one or two vaccination doses were significantly (p = 0.02) more hesitant than those who received more than two doses of the vaccine. Furthermore, a significantly (p = 0.002) high percentage of parents who follow the Ministry of Health (MOH) guidelines for personal preventive measures were hesitant about their children's vaccination. Concerns about side effects (31.4%) and a lack of safety data (31.2%) on the COVID-19 vaccines were the two most significant reasons for parents to develop vaccine hesitancy. Social media (24.3%), poor perceived immunity (16.3 %), and news articles (15.5%) were the top three contributors to this hesitancy. Vaccinated parents were 8.21 times more likely to be vaccination-hesitant than non-vaccinated parents. Additionally, parents with less education and a COVID-19-positive child at home increased the odds of vaccine hesitancy by 1.66 and 1.48 times, respectively. Overall, one-third of the parents were not prepared to vaccinate their children, and one-quarter of the respondents had not decided about vaccination. This study shows that parents in Riyadh are generally reluctant to vaccinate their children against COVID-19. As social media is a primary source of information for parents, public health professionals should utilize the platform to encourage parents to support vaccine acceptance.
ABSTRACT
Asenapine, an atypical antipsychotic agent, has been approved for the acute and maintenance treatment of schizophrenia and manic episodes of bipolar disorder. However, the extensive hepatic metabolism limits its oral bioavailability. Therefore, the objective of the current investigation was to develop sublingual film containing asenapine to enhance the therapeutic efficacy. Sublingual films containing asenapine were fabricated using polyethylene oxide and hydroxypropyl methylcellulose by solvent casting method. Design of experiment was used as a statistical tool to optimize the proportion of the film-forming polymers in order to establish the critical quality attributes of the drug formulation. The process was studied in detail by assessing risk of each step as well as parameters and material attributes to reduce the risk to a minimum. A control strategy was defined to ensure manufacture of films according to the target product profile by evaluation of intermediate quality attributes at the end of each process step. Results of optimized formulations showed rapid disintegration, adequate folding endurance, good percentage elongation, tensile strength, and viscosity. Besides, the results from the in vitro dissolution/ex vivo permeation studies showed rapid dissolution (100% in 6 min) and higher asenapine permeation (~ 80% in 90 min) through the sublingual epithelium. In vivo study indicates greater asenapine absorption (31.18 ± 5.01% of administered dose) within 5 min and was comparable with marketed formulation. In summary, the designing plan to develop asenapine formulation was successfully achieved with desired characteristics of the delivery tool for sublingual administration.
