Knowledge, attitude and practice towards pharmacovigilance and reporting of adverse drug reactions among health care professionals in Albania: A cross-sectional study.

In both developed and developing nations, the rising prevalence of adverse drug reactions (ADRs) and underreporting of ADRs in pharmacovigilance centers have become major problems. The goal of this study was to access the overall knowledge, attitude and practices toward pharmacovigilance and ADRs reporting among Albanian healthcare professionals. A cross-sectional questionnaire-based study was conducted from December 2021 to February 2022 including physicians, community pharmacists and nurses in Tirana, Albania. There were distributed a total of 511 questionnaires to healthcare professionals, where 410 of them were returned, resulting in an 80.23 percent response rate. Physicians and pharmacists compare to nurses had better knowledge about pharmacovigilance and its main purpose. Pharmacists had better knowledge regarding the establishment of the pharmacovigilance law (67.62%) and how to report ADRs (51.43%), Of all, 85.42% of physicians, 74.29% of pharmacists and 40.38% of nurses resulted had a positive attitude towards ADR reporting as a professional obligation, as well as 57.29% of physicians, 58.57% of pharmacists and 22.12% (p < 0.05) of nurses, declared that they have reported ADRs. Only physicians have reported ADRs to the national pharmacovigilance center. The findings of this study show that most of the healthcare professionals in Tirana do not have a thorough understanding of pharmacovigilance techniques.

Emerging compounds and therapeutic strategies to treat infections from Trypanosoma brucei: an overhaul of the last 5-years patents.

INTRODUCTION: Human African Trypanosomiasis is a neglected disease caused by infection from parasites belonging to the Trypanosoma brucei species. Only six drugs are currently available and employed depending on the stage of the infection: pentamidine, suramin, melarsoprol, eflornithine, nifurtimox, and fexinidazole. Joint research projects were launched in an attempt to find new therapeutic options for this severe and often lethal disease. AREAS COVERED: After a brief description of the recent literature on the parasite and the disease, we searched for patents dealing with the proposal of new antitrypanosomiasis agents and, following the PRISMA guidelines, we filtered the results to those published from 2018 onwards returning suitable entries, which represent the contemporary landscape of compounds/strategies against Trypanosoma brucei. In addition, some relevant publications from the overall scientific literature were also discussed. EXPERT OPINION: This review comprehensively covers and analyzes the most recent advances not only in the discovery of new inhibitors and their structure-activity relationships but also in the assessment of innovative biological targets opening new scenarios in the MedChem field. Finally, also new vaccines and formulations recently patented were described. However, natural and synthetic compounds were analyzed in terms of inhibitory activity and selective toxicity against human cells.

Evaluation of In Vitro Capsaicin Release and Antimicrobial Properties of Topical Pharmaceutical Formulation.

(1) Background: Capsaicin is the main capsaicinoid of the Capsicum genus and it is responsible for the pungent taste. Medical uses of the fruits of chili peppers date from the ancient time until nowadays. Most of all, they are used topically as analgesic in anti-inflammatory diseases as rheumatism, arthritis and in diabetic neuropathy. Reports state that the Capsicum genus, among other plant genera, is a good source of antimicrobial and antifungal compounds. The aim of this study was the preparation of a pharmaceutical Carbopol-based formulation containing capsaicin and the evaluation of its in vitro release and antimicrobial and antifungal properties. (2) Methods: It was first stabilized with an extraction method from the Capsicum annuum fruits with 98% ethanol and then the identification and determination of Capsaicin in this extract was realized by HPLC. (3) Results and Conclusions: Rheological analyses revealed that the selected formulation exhibited a pseudo-plastic behavior. In vitro release studies of capsaicin from a Carbopol-based formulation reported that approximately 50% of capsaicin was release within 52 h. Additionally, the Carbopol-based formulation significantly increased the antimicrobial effects of capsaicin towards all tested bacteria and fungi strains.

Synthesis and Biological Evaluation of Carvacrol-Based Derivatives as Dual Inhibitors of H. pylori Strains and AGS Cell Proliferation.

This study reports on the synthesis, structural assessment, microbiological screening against several strains of H. pylori and antiproliferative activity against human gastric adenocarcinoma (AGS) cells of a large series of carvacrol-based compounds. Structural analyses consisted of elemental analysis, 1H/13C/19F NMR spectra and crystallographic studies. The structure-activity relationships evidenced that among ether derivatives the substitution with specific electron-withdrawing groups (CF3 and NO2) especially in the para position of the benzyl ring led to an improvement of the antimicrobial activity, whereas electron-donating groups on the benzyl ring and ethereal alkyl chains were not tolerated with respect to the parent compound (MIC/MBC = 64/64 µg/mL). Ester derivatives (coumarin-carvacrol hybrids) displayed a slight enhancement of the inhibitory activity up to MIC values of 8-16 µg/mL. The most interesting compounds exhibiting the lowest MIC/MBC activity against H. pylori (among others, compounds 16 and 39 endowed with MIC/MBC values ranging between 2/2 to 32/32 µg/mL against all the evaluated strains) were also assayed for their ability to reduce AGS cell growth with respect to 5-Fluorouracil. Some derivatives can be regarded as new lead compounds able to reduce H. pylori growth and to counteract the proliferation of AGS cells, both contributing to the occurrence of gastric cancer.
