Hospital pharmacists' awareness and perspective toward the management of COVID-19 pandemic in the Kingdom of Saudi Arabia.

Objectives: This study investigates the hospital pharmacists' awareness of important facts about the COVID-19 disease and their source of information, as well as their perception. Methods: This cross-sectional study using a self-administered questionnaire was conducted from November 2020 to March 2021 in the Kingdom of Saudi Arabia (KSA). The questionnaire was developed via electronic platform and invitations were sent to pharmacists working in private and government hospitals. A multivariate logistic regression was used to identify factors associated with awareness of COVID-19. Results: A total of 272 pharmacists submitted their responses via weblink. Many pharmacists (n=228, 84%) followed the latest COVID-19 updates on treatment and updated their information mainly through World Health Organization documents (n=151, 56%). Pharmacists working in secondary and tertiary hospitals were relatively five-times times (AOR = 4.59; 95% CI: 1.69-12.8; p-value = 0.003) and three-times (AOR = 2.93; 95% CI: 1.35-6.72; p-value = 0.008) more aware of COVID-19 than those working in primary hospitals. Pharmacists with prior adequate knowledge regarding epidemics and pandemics were two-times more likely to have a good awareness of COVID-19 compared to those who had received none (AOR = 2.15; 95% CI: 1.09-4.35; p-value = 0.030). Conclusions: Half of the pharmacists believed that they received required education in the past about epidemics and pandemics, and many follow the recent COVID-19 updates on medicines predominantly from the WHO followed by the government awareness campaigns. Many pharmacists believed they have a key role in the management of epidemics/pandemics via their hospital pharmacy. However, this study identified certain awareness gaps regarding COVID-19, highlighting areas of improvement.

Pharmacokinetic and pharmacodynamic interaction of Rosuvastatin calcium with guggulipid extract in rats.

BACKGROUND & OBJECTIVES: Rosuvastatin calcium (RC) is a potent and competitive synthetic inhibitor of HMG-CoA reductase used for the treatment of dyslipidemia. Guggulipid obtained from Commiphora mukul is used in the treatment of a wide variety of diseases such as atherosclerosis, hypercholesterolemia, rheumatism, and obesity. The present study evaluates the pharmacokinetic and pharmacodynamic interactions between RC and the standardized guggulipid extract in rats. MATERIALS AND METHODS: The guggulipid extract was standardized for the presence of guggulsterones. The pharmacokinetic interaction was determined after a single dose administration of RC alone or in combination with the guggulipid extract or after multiple-dose administration of RC alone or RC along with the guggulipid extract for 14 days. To determine the pharmacodynamic interaction, RC and guggulipid extract were administered to hyperlipidemic rats for 14 days. The level of significance was determined using unpaired student's t-test, one way ANOVA, the post-ANOVA Tukey test. RESULTS: Standardization of guggulipid extract showed it contains 7.5%w/w of guggulsterones. Guggulipid extract increased the bioavailability of RC in both single-dose and multiple-dose studies. Guggulipid extract reduced the rate of absorption (Ka) of RC but showed an increase in maximum serum concentration (Cmax). An in-vitro study using isolated rat intestine revealed that guggulipid extract decreased the rate of absorption of RC in the intestinal lumen. The hypolipidemic activity of RC was augmented by the guggulipid extract in hyperlipidemic rats. INTERPRETATION & CONCLUSION: Therefore it is concluded that guggulipid extract increases the bioavailability of RC by delaying its Ka and augments its hypolipidemic action. However, it is recommended that a combination of RC with guggulipid extract should be used only after an adverse effect(s) of this combination are determined.

Haematotoxic effects of methanolic extract of Boswellia sacra oleo gum resin (frankinccense) in rats.

In several parts of the world, Boswellia sacra Fluck. is one of the most commonly used herbs for the treatment of arthritis. Its usage should be validated in light of recent findings of haematotoxicity. This study was aimed to determine the effect of chronic administration of standardized methanolic extract of frankincense on blood cell count in experimental animals. Using high-performance liquid chromatography, the active constituents of B. sacra extract; boswellic acids were analyzed. The effect of three different doses of the extract (250, 500, and 1000 mg/kg) on different blood cells and associated parameters was investigated. The behavior, food, and water consumption of the rats were recorded. Boswellic acids were present in varying amounts with α-boswellic acid and ß-boswellic acid present in more amounts compared to other boswellic acids in the extract. All three doses tested had no effect on the animals' behavior, food consumption, or weight gain. The administration of a low (500 mg/kg) and high (1000 mg/kg) dose of the extract resulted in a non-dose dependent reduction in MCH (p < 0.01 and p < 0.05, respectively), but no other blood parameters were significantly affected. The B. sacra extract produces hypochromic normocytic anemia in rats at higher doses of 500 and 1000 mg/kg and this effect was not dose-dependent.

Salvadora persica protects libido by reducing corticosterone and elevating the testosterone levels in chronic cigarette smoke exposure rats.

BACKGROUND & OBJECTIVES: Cigarette smoke is associated with several diseased states including defects in reproductive behavior. Salvadora persica (S. persica) known as the toothbrush plant is reported to possess several pharmacological properties including antidepressants and anxiolytics. The present research was done to determine the libido-protective effect of S. persica in chronic cigarette smoke-exposed rats. MATERIALS AND METHODS: The decoction of freshly dried roots of S. persica (50, 100, and 200 mg/kg, oral) was administered to the chronic-cigarette smoke-exposed adult rats. The parameters related to libido were recorded using a close-camera circuit (CCTV). Serum corticosterone and testosterone levels were estimated. Further, the phytochemical constituents were identified in the decoction. The data obtained were analyzed using one-way analysis of variance and significance was considered at p < 0.05. RESULTS: The observation from the study revealed that cigarette smoke exposure reduces the sexual activity parameters significantly (p < 0.01), besides elevated the serum corticosterone and suppressed the testosterone levels in rats. Administration of S. persica at 200 mg/kg improved significantly (p < 0.05) the parameters related to libido. The decoction also reversed the changes in the levels of tested hormones in serum. INTERPRETATION AND CONCLUSION: The findings indicate that a 200 mg/kg S. persica decoction can protect libido in chronic cigarette smoke-exposed rats. The activity may be due to the presence of several phytoconstituents such as alkaloid, flavonoids and phytosterols that might produce vasodilatory effect in sex organs and enhance the synthesis of endogenous testosterone to improve libido characteristics weakened by chronic cigarette smoke exposure.
