Furthermore, it explores whether the process incorporates wider evidence-based methods of change. © 2019 The Authors Child & Family Social Work published by John Wiley & Sons Ltd.Background Acne vulgaris is a self-limiting condition that may affect the patients quality of life. The most efficacious treatment of choice for acne is isotretinoin. IACS-10759 in vitro However, adverse effects and relapse of acne after completing an isotretinoin course pose major hurdles for treatment compliance and adherence. Method The authors conducted a cross-sectional study using a self-administered questionnaire. The prevalence and risk factors associated with the relapse of acne following isotretinoin use among Saudi patients were assessed. In addition, the reasons for discontinuing treatment, extent of awareness about isotretinoin use-associated teratogenicity, side effects such as liver enzymes impairments, dry mouth, skin, eyes, and the number of people using isotretinoin without a prescription were determined. Results Four hundred and twenty seven acne vulgaris patients (mean age 25.0 years, female 83%) were included in this study. Of the 57% subjects who used isotretinoin, 45.12% patients showed relapse. The daily dose of oral isotretinoin of 20 and 40 mg/day was taken by 80% in both group of patients, and the mean duration of isotretinoin use was 7.15(±4.5) months. Those patients who were taking higher doses of oral isotretinoin reported having more relapses.Although a majority of patients received the medication through prescription, unfortunately, they were not aware of relapse and side effects. Conclusion Almost half of the patients showed relapse of acne after using isotretinoin. A lack of understanding regarding relapse and side effects indicates a need to improve public and professional awareness of isotretinoin. © 2020 The Author(s).Objectives The aim of this study was to evaluate patients' self-reported adherence to dual antiplatelet therapy (DAPT) and determine the factors associated with premature discontinuation of DAPT. Methods The cross-sectional interview-based study was conducted among adult outpatients who visited the outpatient department of King Khalid University Hospital, Cardiac Center in Riyadh, Saudi Arabia, over a period of 3 months from May to July of 2016. Medication adherence was assessed using the Self-efficacy for Appropriate Medication Use Scale (SEAMS), which is composed of 13 items with a 3-point Likert scale. Results A total of 192 patients participated in the study. The majority of the participants were male (82.1%), and the mean age was 55.66 ± 10.80 years. More than 84% (84.4%) of the patients reported that they were "confident" in taking several medications each day. The minimum and maximum SEAMS scores were 22 and 39, respectively, with the mean score being 30.8 ± 3.5. Almost all patients had moderate scores and adherence; only one patient got a score of 39. Among sociodemographic characteristics, only health insurance and income were significantly associated with the medication adherence score (p  less then  0.05). Conclusions Study results concluded that patients had a moderate level of adherence towards DAPT in Saudi Arabia, however Patient education on DAPT is essential to improve adherence to medication treatment. More effective intentions and education methods should be developed to improve long-term DAPT adherence. © 2020 The Author(s).The antidiabetic drugs metformin, gliclazide and glipizide have been widely used and studied in terms of pharmacological and antidiabetic effects, and their individual stability has been studied in the literature. However, the drugs' combined stability profiling remains poorly understood, and hence the aim of this study was to investigate the collective stability profiling of different combinations at various controlled conditions. Degradation assessments were carried out on metformin, glipizide and gliclazide by applying a stability-indicating HPLC method that was developed and validated in accordance with ICH guidelines. Glipizide, gliclazide, metformin and the binary mixtures (metformin/glipizide and metformin/gliclazide) were subjected to different forced degradation conditions and were detected at 227 nm by an isocratic separation on an Alltima CN column (250 mm × 4.6 mm × 5µ) utilizing a mobile phase that consists of 20 mM ammonium formate buffer (pH 3.5) and acetonitrile at a ratio of (4555, v/v). The method is linear (R2 = 0.9999) at the concentration range 2.5-150 µg/ml for metformin and 1.25-150 µg/ml for sulfonylureas respectively and offers a specific and sensitive tool for their determination in less then 10 min chromatographic run. All drug peaks were sharp and well separated. Stress degradation revealed that metformin has a remarkable sensitivity to alkaline stress, glipizide was more sensitive to thermal degradation while gliclazide exhibited almost full degradation in acidic, alkaline and oxidative stress conditions. © 2020 The Author(s).The aim of this study was the development of griseofulvin (GRI) loaded β-cyclodextrin (β-CD) based nanosponges for bitter taste masking, improving dissolution rate and oral bioavailability. Plain NS (NS1 NS2 and NS3) were fabricated by reacting β-CD with the cross-linker diphenyl carbonate at different molar ratios (12, 14 and 16, respectively) using ultrasonication method. The NS2 provided both highest %yield and GRI solubilization enhancement. Thus, the drug was loaded in NS2 at different NS2 drug weight ratios in presence or absence of 0.25%w/w polyvinylpyrolidone (PVP k30). The GRI loaded NS (F1) that provided highest drug loading capacity and entrapment efficiency (47.20 ± 0.38%, 84.91 ± 0.30%, respectively) was morphologically examined using scanning electron microscopy (SEM). Also, Particle size, zeta potential, differential scanning calorimetry (DSC), Fourier transform infra-red (FT-IR), nuclear magnetic resonance (NMR) spectroscopy, in-vitro release, taste masking potential were evaluated. Moreover, in-vivo Pharmacokinetic studies were performed on rats. The F1 showed particle size 665.9 ± 13.8 nm and zeta potential -21.5 ± 0.7 mV. The DSC and FT-IR analysis confirmed the complexation of GRI with NS2. Nanosponges (F1) provided 3.19, folds increase in dissolution efficiency %, 2.13 and 3.78 folds increase in Cmax and AUC0-48 compared to plain GRI. Taste masking evaluation confirmed the potential of GRI nanosponges (F1) in masking the bitter taste of GRI completely. The study confirmed that complexation of GRI with NS would be a viable approach for masking the bitter taste of GRI and improving oral bioavailability, that Cmax, Tmax and AUC 0-48 were significantly higher for the developed formulation (F1). © 2020 Published by Elsevier B.V. on behalf of King Saud University.
