Abstract
CONTEXT Glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter-2 inhibitors reduce weight and improve insulin sensitivity via different mechanisms. OBJECTIVE The efficacy of once-weekly exenatide (EQW) and dapagliflozin (DAPA) alone and coadministered (EQW/DAPA), DAPA/extended-release (ER) metformin (DAPA/MET), and phentermine topiramate extended release (PHEN/TPM) on metabolic parameters, body composition, and sex hormones were examined in obese women with PCOS. METHODS Nondiabetic women (n = 119; aged 18-45 years) with a body mass index (BMI) greater than 30 and less than 45 and polycystic ovary syndrome (National Institutes of Health criteria) were randomly assigned in a single-blinded fashion to EQW (2 mg weekly); DAPA (10 mg daily), EQW/DAPA (2 mg weekly/10 mg daily), DAPA (10 mg)/MET (2000 mg XR daily), or PHEN (7.5 mg)/TPM (46 mg ER daily) treatment for 24 weeks. Study visits at baseline and 24 weeks included weight, blood pressure (BP), waist (WC) measures, and body composition evaluated by dual-energy x-ray absorptiometry (DXA). Oral glucose tolerance tests were conducted to assess glycemia and mean blood glucose (MBG), and compute insulin sensitivity (SI) and secretion (IS) measures. Sex steroids, free androgen index (FAI), and lipid profiles were measured in the fasting sample. RESULTS EQW/DAPA and PHEN/TPM resulted in the most loss of weight and total body fat by DXA, and WC. Despite equivalent reductions in BMI and WC with PHEN/TPM, only EQW/DAPA and EQW resulted in significant improvements in MBG, SI, and IS. Reductions in fasting glucose, testosterone, FAI, and BP were seen with all drugs. CONCLUSION Dual therapy with EQW/DAPA was superior to either alone, DAPA/MET and PHEN/TPM in terms of clinical and metabolic benefits in this patient population.

Abstract
AIMS: Coronavirus disease 2019 (COVID-19) is caused by a novel severe acute respiratory syndrome coronavirus 2. It can lead to multiorgan failure, including respiratory and cardiovascular decompensation, and kidney injury, with significant associated morbidity and mortality, particularly in patients with underlying metabolic, cardiovascular, respiratory or kidney disease. Dapagliflozin, a sodium-glucose cotransporter-2 inhibitor, has shown significant cardio- and renoprotective benefits in patients with type 2 diabetes (with and without atherosclerotic cardiovascular disease), heart failure and chronic kidney disease, and may provide similar organ protection in high-risk patients with COVID-19. MATERIALS AND METHODS DARE-19 (NCT04350593) is an investigator-initiated, collaborative, international, multicentre, randomized, double-blind, placebo-controlled study testing the dual hypotheses that dapagliflozin can reduce the incidence of cardiovascular, kidney and/or respiratory complications or all-cause mortality, or improve clinical recovery, in adult patients hospitalized with COVID-19 but not critically ill on admission. Eligible patients will have ≥1 cardiometabolic risk factor for COVID-19 complications. Patients will be randomized 1:1 to dapagliflozin 10 mg or placebo. Primary efficacy endpoints are time to development of new or worsened organ dysfunction during index hospitalization, or all-cause mortality, and the hierarchical composite endpoint of change in clinical status through day 30 of treatment. Safety of dapagliflozin in individuals with COVID-19 will be assessed. CONCLUSIONS DARE-19 will evaluate whether dapagliflozin can prevent COVID-19-related complications and all-cause mortality, or improve clinical recovery, and assess the safety profile of dapagliflozin in this patient population. Currently, DARE-19 is the first large randomized controlled trial investigating use of sodium-glucose cotransporter 2 inhibitors in patients with COVID-19.

United States Pharmacopeia Safety Review of Willow Bark.
Oketch-Rabah, HA, Marles, RJ, Jordan, SA, Low Dog, T
Planta medica. 2019;(16):1192-1202
Abstract
Willow bark (Salix spp.) is an ingredient in some dietary supplements. No serious adverse effects were reported from trials of willow bark extracts delivering 120 - 240 mg salicin (the purported active constituent) daily for up to 8 weeks. All studies involved adults only; none involved special subpopulations such as pregnant or breastfeeding women, or children. The most common adverse effects associated with willow bark are gastrointestinal; a few allergic reactions were also reported. Some publications advise caution when taking willow bark. There is a risk of increased bleeding in vulnerable individuals, salicylates cross the placenta and are eliminated slowly in newborns, some persons are sensitive or allergic to aspirin, and children are at risk of Reye syndrome. Concurrent use with other salicylate-containing medicines increases these risks. Metabolism of 240 mg salicin from willow bark could yield 113 mg of salicylic acid, yet dietary supplement products are not required to be labeled with warnings. In contrast, over-the-counter low-dose aspirin (81 mg strength), which delivers 62 mg salicylic acid, is required by law to include cautions, warnings, and contraindications related to its use in pregnant and nursing women, children, and other vulnerable subpopulations, e.g., those using anticoagulants. In the interest of protecting public health, the United States Pharmacopeia has included a cautionary labeling statement in the United States Pharmacopeia Salix Species monograph as follows: "Dosage forms prepared with this article should bear the following statement: 'Not for use in children, women who are pregnant or nursing, or by persons with known sensitivity to aspirin.'".

Abstract
BACKGROUND Empagliflozin is a sodium-glucose-cotransporter-2 inhibitor that improves cardiovascular risk and promotes weight loss in patients with type-2 diabetes. Polycystic ovary syndrome (PCOS) is associated with obesity and increased cardiovascular risk; therefore, empagliflozin may be of benefit for these women. The aim of this study was to compare the effects of empagliflozin vs metformin on anthropometric and body composition, hormonal and metabolic parameters in women with PCOS. MATERIALS AND METHODS A randomized open-label study was conducted in women with PCOS who were randomized to either empagliflozin 25 mg (n = 19) or metformin 1500 mg (n = 20) daily for 12 weeks. The main outcomes assessed were changes in anthropometric and body composition, hormonal and metabolic parameters. RESULTS Univariate analysis showed significant differences in weight (empagliflozin: -1.4 ± 3.2% vs metformin: 1.2 ± 2.3%; P = 0.006), body mass index (empagliflozin: -1.4 ± 3.2% vs metformin: 1.1 ± 2.2%; P = 0.006), waist circumference (empagliflozin: -1.6 ± 2.8% vs metformin: 0.2 ± 2.1%; P = 0.029) and hip circumference (empagliflozin: -2.0 ± 3.0% vs metformin: 1.1 ± 1.9%; P = 0.001), basal metabolic rate (empagliflozin: -1.8 ± 2.9% vs metformin: 0.1 ± 1.9%, P = 0.024) and fat mass (empagliflozin: -0.7 ± 4.9% vs metformin, 3.2 ± 5.0%; P = 0.023) between the empagliflozin and the metformin groups. These differences were confirmed in linear regression analysis after adjustment for relevant covariates. There were no significant changes in hormonal or metabolic parameters between both groups. CONCLUSION There was a significant improvement in anthropometric parameters and body composition, in overweight and obese women with PCOS after 12 weeks of treatment with empagliflozin compared to metformin, although no changes were seen in hormonal or metabolic parameters.

Diabetes & metabolic syndrome. 2019;(1):284-288
Abstract
INTRODUCTION Dapagliflozin is an antidiabetic drug that has been used as a member of the new antidiabetic drug group that acts by inhibiting SGLT-2 and increasing urinary glucose excretion. With numerous controlled experimental studies of dapagliflozin, evaluation of real-life data after entry into clinical practice is an important condition. In our study, the effects of dapagliflozin on glycemic control and anthropometric measurements were investigated retrospectively. METHODS A-total of thirty-one type 2 diabetics were enrolled in the study. Data of before dapagliflozin and three and six months of treatment were recorded. RESULTS Dapagliflozin reduced HbA1c levels by 0,9% at 3 months and 0,79% at 6 months. Fasting plasma glucose decreased 41,1 mg/dl in the 3rd and 42 mg/dl in the 6th, postprandiyal glucose decreased 86,3 mg/dl in the 3rd and 74,2 mg/dl in the 6th. In the 3rd and 6th, body weights decreased by 3,3 kg and 4,2 kg, BMI decreased by 1,3 kg/m2 and 1,6 kg/m2 respectively. Similarly, it was observed that the waist circumference decreased by 1,3 cm at the end of 6th. CONCLUSION Our data show that SGLT-2 inhibitors provide glycemic control with reduce HbA1c levels by 0.8-0.9%, and reduce fasting and postprandial plasma glucose levels without increasing the risk of hypoglycemia and causing weight lose around 5% at the six mounths. SGLT-2 inhibitors were found to be more effective in reduce postprandiyal plasma glucose in patients who did not use insulin and fasting plasma glucose in patients with diabetes mellitus less than 10 years.

Abstract
INTRODUCTION Dapagliflozin is a sodium-glucose cotransporter 2 inhibitor that improves glycemic control in patients with type II diabetes mellitus which increasing urinary glucose excretion. With numerous controlled experimental studies of dapagliflozin, evaluation of real-life data after entry into clinical practice is an important condition. In our study, the effects of dapagliflozin (10 mg) on lipid profile were investigated retrospectively. METHODS A total of thirty-one type 2 diabetic patients with HbA1c level between 6,5% and 13%, aged 45-80 years and whose body mass index higher than 20 kg/m2 were enrolled to the study. Data before dapagliflozin treatment and three and six months results were recorded. RESULTS Dapagliflozin reduced HbA1c levels by 0,9% at 3 months and 0,79% at 6 months. Total cholesterol level decreased 17,6 mg/dl, LDL cholesterol level decreased 13,4 mg/dl and triglyceride level by 25.9 mg/dl at the 6th months and it is observed that there is no serious side effect on the usage for 6 months. CONCLUSION There are conflicting results about the effect of SGLT2 inhibitors on the lipid profile in the literature. According to our data, dapagliflozin has positive effects on lipid profile as weight and glycemic control and it is well tolerated. Therefore, dapagliflozin therapy is beneficial because of the positive change in lipid profile and weight loss in diabetic patients with overweight and hyperlipidemia.

A complete review of empagliflozin: Most specific and potent SGLT2 inhibitor used for the treatment of type 2 diabetes mellitus.
Chawla, G, Chaudhary, KK
Diabetes & metabolic syndrome. 2019;(3):2001-2008
Abstract
Sodium-glucose co-transporter 2 (SGLT2) inhibitors are the latest class of drugs to be introduced for the treatment of type 2 diabetes mellitus (T2DM). They reduce hyperglycemia by increasing urinary glucose excretion and exert favorable effects beyond glucose control with consistent body weight, blood pressure, and serum uric acid reductions. Empagliflozin is a potent SGLT2 inhibitor used to improve glycemic control in adults with T2DM. It has the highest SGLT2 specificity among all the clinically used or currently tested SGLT2 inhibitors. Low risk of hypoglycemia, absence of weight gain and demonstrated cardiovascular risk reduction support its consideration as a first line medication in addition to metformin for patients with T2DM and cardiovascular disease. Mostly reported adverse events are genital mycotic infections, while urinary tract infections and events linked to volume depletion are rather rare. This review covers the complete information on empagliflozin including the history of its development, synthesis, pharmacology and different methods which have been reported for its analysis.
