Cyclophosphamide (CP) is a widely used drug in cancer chemotherapy and immunosuppression, which could cause toxicity of the normal cells due to its toxic metabolites. Probucol, a cholesterol‐lowering drug, acts as potential inhibitor of DNA damage and shows to protect against doxorubicin‐induced cardiomyopathy by enhancing the endogenous antioxidant system including glutathione peroxidase, catalase and superoxide dismutase. This study examined the possible protective effects of probucol, a lipid‐lowering compound with strong antioxidant properties, against CPinduced cardiotoxicity. This objective could be achieved through studying the gene expression‐based on the possible protective effects of probucol against CP‐induced cardiac failure in rats. Adult male Wistar albino rats were assigned into four treatment groups: Animals in the first (control) and second (probucol) groups were injected intraperitoneally with corn oil and probucol (61 mg/kg/day), respectively, for two weeks. Animals in the third (CP) and fourth (probucol plus CP) groups were injected with the same doses of corn oil and probucol (61 mg/kg/day), respectively, for one week before and one week after a single dose of CP (200 mg/kg, I.P.). The p53, Bax, Bcl2 and oxidative genes signal expression were measured by real time PCR. CP‐induced cardiotoxicity was clearly observed by a significant increase in serum creatine phosphokinase isoenzyme (CK‐MB) (117%), lactate dehydrogenase (LDH) (64%), free (69%) and esterified cholesterol (42%) and triglyceride (69%) compared to control group. In cardiac tissues, CP significantly increases the mRNA expression levels of apoptotic genes, p53 with two‐fold and Bax with 1.6‐fold, and decreases the anti‐apoptotic gene Bcl2 with 0.5‐fold. Moreover, CP caused downregulation of antioxidant genes, glutathione peroxidase, catalase, and superoxide dismutase and increased the lipid peroxidation and decreased adenosine triphosphate (ATP) (40%) and ATP/ADP (44%) in cardiac tissues. Probucol pretreatment not only counteracted significantly the CP‐induced increase in cardiac enzymes and apoptosis but also induced a significant increase in mRNA expression of antioxidant enzymes and improved ATP, ATP/ADP, glutathione (GSH) in cardiac tissues. In conclusion, data from the present study suggest that probucol prevents the development of CP‐induced cardiotoxicity by a mechanism related, at least in part, to its ability to increase mRNA expression of antioxidant genes and to decrease apoptosis in cardiac tissues with the consequent improvement in mitochondrial oxidative phosphorylation and energy production.

This was a questionnaire-based cross-sectional study that explored the impact of the COVID-19 pandemic on the availability of essential medicine and personal protective equipment (PPE) in Saudi Arabia. Purposive sampling technique was used to recruit individuals working in the supply chain departments in different healthcare sectors in Saudi Arabia. One hundred and three pharmaceutical and medical supply chain employees participated in the study. Most of the participants (58.3%) were aged ≥35 years, male (65%), and pharmacists (92.2%). The majority of participants had at least two years of experience in supply chain (77.6%), worked in public hospitals (95.15%), and were mostly working at healthcare institutions located in Riyadh province (59.2%). Approximately 51% of the participants reported shortages of 10 or more essential drugs. Tocilizumab, hydroxychloroquine, lopinavir/ritonavir, ribavirin, dexamethasone, enoxaparin, interferon beta-1b, cisatracurium besylate, prednisolone, hydrocortisone, methimazole, and methylprednisolone were reported to be in shortage by at least 8% of the participants. Almost 70% of the participants reported that the pandemic did not significantly impact the prices of prescription drugs in shortage (e.g., ≥25%). Moreover, about 70% of the participants reported direct purchasing or procurement of drugs in shortage. Surgical masks, face shields, medical gowns, and N95 respirators were reported to be in short supply by 33% or more of the participants. Approximately 53% of the participants reported the prices of PPE in shortage had seen an increase by at least 25% during the pandemic. Although the COVID-19 pandemic has caused a significant disruption in the global pharmaceutical supply chain, its impact was largely manageable in Saudi healthcare institutions. This can be attributable to multiple reasons such as the effective exchange programs between hospitals and the drastic increase in public healthcare spending to ameliorate the negative impact of the pandemic on the healthcare sector.

The trends in the quality of biomedical education in pharmacy schools have witnessed significant changes in the 21st century. With the advent of continuous revision and standardization processes of medical curricula throughout the world, the focus has been on imparting quality education. This pedagogic paradigm has shifted to pharmacy schools. In Saudi Arabia, the concept of "medical and pharmacy education" is relatively new as mainstream pharmacy curriculum and universities were established only half a century ago. This period has seen major changes in the dimension of "pharmacy education" to keep pace with the education systems in the United States and Europe. As our knowledge and perceptions about pharmaceuticals change with time, this motivates educators to search for better teaching alternatives to the ever increasing number of enthusiastic and budding pharmacists. Recently, the academic system in Saudi Arabian Pharmacy has adopted a more clinically-oriented Pharm. D. curriculum. This paper deals with the major changes from the inception of a small pharmacy faculty in 1959, the College of Pharmacy at the King Saud University, Riyadh, to the model of progress and a prototype of pharmacy colleges in Saudi Arabia. The fifty year chronological array can be regarded as an epitome of progress in pharmacy education in Saudi Arabia from its traditional curriculum to the modern day Pharm. D. curriculum with a high population growth and expanding health care sector, the demand for qualified pharmacists is growing and is projected to grow considerably in the future. The number of pharmacy graduates is increasing each year by many folds and to meet the needs the system lays stress upon a constant revising and updating of the current curriculum from a global perspective.

Complementary and Alternative Medication (CAM) is commonly used among women with breast cancer to improve their quality of life (QoL). However, few studies examine the prevalence of CAM and its' relation to the patients' QoL among women with breast cancer. A cross-sectional study was conducted among 95 women with breast cancer at a tertiary hospital in Saudi Arabia. The outcome measure of interest was the QoL. The correlation was used to assess the association between CAM use and QoL. Bivariate and multivariate analyses were used to examine the factors that affect the use of CAM. The data was analysed using Statistical Package for the Social Sciences (SPSS) version 24.0. CAM use was reported by 81.1% of the study participants. The most commonly used CAM therapy was spiritual therapy 70.5%, followed by honey 36.8%, olive oil 24.2% and 23.2% herbal therapy. We found that those who were undergoing cancer treatment had a significantly higher percentage of CAM usage as compared to those not undergoing cancer therapy (72.6% vs. 8.4%, P=0.008). With regards to QoL, there was a statistically significant difference between CAM users and non-CAM users in global health status (73.2% vs. 64.8%, P = 0.049). CAM therapy was commonly used among women in our study sample which was correlated with higher overall global QoL. As CAM is widely used, health care providers may need to discuss the use of CAM with breast cancer women and be up to date on the benefits and risk of CAM use through well-equipped training programs and workshops.

Background: Medication non-adherence is a complex multifactorial phenomenon impacting patients with various health conditions worldwide. Therefore, its detection can improve patient outcomes and minimize the risk of adverse consequences. Even though multiple self-reported medication adherence assessment scales are available, very few of them exist in Arabic language. Therefore, the aim of this study was to validate a newly translated Arabic version of the Adherence to Refills and Medications Scale (ARMS) among patients with chronic health conditions. Methods: This is a single-center cross-sectional study that was conducted between October 10th 2018 and March 23rd 2021. ARMS was first translated to Arabic using the forward-backward translation method. The translated scale was then piloted among 21 patients with chronic health conditions (e.g., diabetes, hypertension, etc.…) to examine its reliability and comprehensibility using the test-retest method. Thereafter, the Arabic-translated ARMS was self-administered to adult patients aged ≥18 years with chronic health conditions visiting the primary care clinics of a university-affiliated tertiary care hospital in Riyadh, Saudi Arabia. Construct validity was examined using factor analysis with varimax rotation. Results: Of the 264 patients who were invited to participate, 202 (76.5%) consented and completed the questionnaire. Most of the participants were males (69.9%), married (75.2%), having a college degree or higher (50.9%), retired or unemployed (65.2%), aged ≥ 50 years (65.2%), and are diabetic (95.9%). The 12-item Arabic-translated ARMS mean score was 17.93 ± 4.90, and the scale yielded good internal consistency (Cronbach’s alpha = 0.802) and test-retest reliability (Intraclass correlation coefficient = 0.97). Two factors were extracted explaining 100% of the of the total variance (factor 1 = 52.94% and factor 2 = 47.06%). Conclusions: The 12-item Arabic version of ARMS demonstrated good validity and reliability. Therefore, it should help in the detection of medication non-adherence among Arabic-speaking patient population and minimize the risk of adverse consequences.

Objectives: The utilization rate of herbal and dietary supplements among the Saudi population is reported to be high. However, the utilization rate and types of herbal and dietary supplements during the COVID-19 pandemic are largely unknown. Methods: This was an online questionnaire-based cross-sectional study that used convenience sampling and social media platforms (Telegram®, Twitter®, and WhatsApp®) to disseminate a 12-item questionnaire across the Saudi general public aged 18 years and above. The questionnaire inquired about the sociodemographic characteristics (e.g., age, gender, education, geographical location), presence of chronic health conditions and the use of prescription medications, awareness of the viral nature of COVID-19 infection and its common symptoms, and the commonly utilized herbal and/or dietary supplements. Results: Sixty-four percent of the 1473 participants reported using herbal and/or dietary supplements for the purpose of boosting their immune system to prevent COVID-19 infection. In addition, 88.2% of the respondents were misinformed about the manifestation of COVID-19 symptoms. Most of the participants were Saudi (91.9%), aged 49 years and younger (83%), female (52%), and healthy (81%). Honey (46%), lemon (45%), ginger (36%), vitamin C (32%), black seed (26%), garlic (26%), and turmeric (19%) were the most commonly used herbal and/or dietary supplements by the participants. Saudi nationals (OR = 1.67, 95% CI: 1.08 to 2.6, p = 0.02), older adults (OR = 1.30, 95% CI:1.10 to 1.55, p = 0.002), and those taking prescription medications had higher odds of using dietary and/or herbal supplements (OR = 3.31, 95% CI: 2.61 to 4.18, p < 0.0001). Conclusion: The utilization rate of herbal and dietary supplements among the Saudi public during the COVID-19 pandemic is high. Future studies should examine the impact of different public awareness campaigns aimed at improving the public knowledge of the risk and benefits associated with the use of different commonly utilized herbal and dietary products identified in this study.
