In the current work, a simple, economical, accurate, and precise HPLC method with UV detection was developed to quantify Favipiravir (FVIR) in spiked human plasma using acyclovir (ACVR) as an internal standard in the COVID-19 pandemic time. Both FVIR and ACVR were well separated and resolved on the C18 column using the mobile phase blend of methanol:acetonitrile:20 mM phosphate buffer (pH 3.1) in an isocratic mode flow rate of 1 mL/min with a proportion of 30:10:60 %, v/v/v. The detector wavelength was set at 242 nm. Maximum recovery of FVIR and ACVR from plasma was obtained with dichloromethane (DCM) as extracting solvent. The calibration curve was found to be linear in the range of 3.1–60.0 µg/mL with regression coefficient (r²) = 0.9976. However, with acceptable r², the calibration data’s heteroscedasticity was observed, which was further reduced using weighted linear regression with weighting factor 1/x. Finally, the method was validated concerning sensitivity, accuracy (Inter and Intraday’s % RE and RSD were 0.28, 0.65 and 1.00, 0.12 respectively), precision, recovery (89.99%, 89.09%, and 90.81% for LQC, MQC, and HQC, respectively), stability (% RSD for 30-day were 3.04 and 1.71 for LQC and HQC, respectively at −20 °C), and carry-over US-FDA guidance for Bioanalytical Method Validation for researchers in the COVID-19 pandemic crisis. Furthermore, there was no significant difference for selectivity when evaluated at LLOQ concentration of 3 µg/mL of FVIR and relative to the blank.

Vitamin D is necessary for maintaining and regulating calcium levels; thus, insufficiency of vitamin D increases the risk of many chronic diseases. This study aimed to examine vitamin D levels among Jordanian and Iraqi volunteers and find the relation between vitamin D level and lipid profile patients. Vitamin D levels were evaluated using enzyme-linked immunosorbent assay. For young healthy group subjects, vitamin D levels were 20.60 ± 5.94 ng/mL for Jordanian and 27.59 ± 7.74 ng/mL for Iraqi. Vitamin D concentrations for young males and females were 25.82 ± 8.33 ng/mL and 21.95 ± 6.39 ng/mL, respectively. Females wearing hijab were 20.87 ± 6.45 ng/mL, while uncovered females were 23.55 ± 6.04 ng/mL. For >40 years Iraqi subjects, vitamin D level for healthy was 29.78 ± 9.49 ng/mL and 23.88 ± 7.93 ng/mL for hyperlipidemic subjects. Vitamin D levels for overweight and obese healthy groups were significantly higher () than those for the hyperlipidemic patients groups. Vitamin D levels for males were significantly higher than females and were significantly higher for healthy than those hyperlipidemic Iraqi patients. These findings showed that vitamin D levels are affected by age, nationality, gender, and health statues and highlight the importance of vitamin D supplementation for groups with low levels particularly old, hijab wearing females, and hyperlipidemic groups.

Introduction: Antimicrobial resistance is a serious global health concern. It has considerable implications on societies' health and resources. In Jordan, there is a large Iraqi community due to the ongoing turmoil in Iraq. Unfortunately, health awareness and practices of this community are under-investigated due to scarcity of research. This paper assesses the awareness of antibiotic use and antimicrobial resistance in the Iraqi community residing in Amman, Jordan. Their level of interaction with health care professionals regarding antibiotics and differences in their antibiotic use between Iraq and Jordan are also discussed. Methodology: A cross-sectional questionnaire-based survey involving randomly selected Iraqis residing in Amman, Jordan was conducted. Results: The study involved 508 participants. Sixty-two percent of participants agreed with buying antibiotics without a prescription, 29% agreed with obtaining antibiotics from friends or relatives, and 46% agreed with keeping leftover antibiotics for future use. Furthermore, 60% disagreed with not completing an antibiotic course and almost 90% of the sample listed viral diseases as an indication for antibiotics. Forty-four percent of participants abided by physicians’ instructions on antibiotic use. Half of the participants believed that pharmacists provided instructions on antibiotics all the time, whereas physicians were perceived to do so by 29% of participants. Conclusions: Gaps exist in knowledge of antibiotic use and reasons for antimicrobial resistance among Iraqis residing in Jordan. These gaps should serve in planning educational campaigns to raise the community’s awareness of responsible antibiotic use. Law enforcement to restrict access to antibiotics is also pivotal to tackle their misuse.

Aim: The aim is to develop and validate a single quantitative method for all DPP-IV inhibitors (Alogliptin, Vildagliptin, Sitagliptin, Saxagliptin, and Linagliptin). Background: Metformin is the most used antihyperglycemic drug in diabetes, therefore it is preferred to be combined with other classes of antihyperglycemic drugs, specially gliptins. Formulating these two drug classes in one pharmaceutical dosage form would be more efficacious to control hyperglycemia than having either drug alone. Objective: This study was designed and performed to develop a new, simple, and reliable method of analysis for assaying simultaneously five types of gliptins (Alogliptin, Linagliptin, Saxagliptin, Sitagliptin, and Vildagliptin) and Metformin, which has not been documented before. Methods: The present method was carried out using a C18 column (250x4.6 mm), 5μm particle size, mobile phase consisting of water to acetonitrile ratio 85:15% (v/v) and the pH was set by orthophosphoric acid at 3, 10 μl injection volume, 0.5 ml flow rate, 25oC temperature, and the eluent was monitored at 232 nm. Results: The assay's selectivity showed no interference with inactive ingredients in the formulation, and the %recovery from each drug dosage forms at three different concentrations were within the acceptable limits of the ICH guidelines. Although the method showed robustness towards the flow rate, it showed significant change at 230 or 234 nm. Conclusion: The present analytical method is comprehensive and universal for measuring the five drugs and Metformin. Such an analytical method can be applied to the present available combined drug dosage forms of Metformin and one type of gliptins and the possible future of triple combinations of two gliptins and Metformin.
