An Overview of Pyridazinone Analogs: Chemical and Pharmacological Potential.

Pyridazinones are classical molecules that occupy an important place in heterocyclic chemistry, and since their discovery, they have been widely developed. The introduction of new functional groups into pyridazinone structures has enabled the synthesis of a large diversity of compounds. The pharmacological and agrochemical importance of pyridazinone derivatives has aroused the interest of chemists and directed their research toward the synthesis of new compounds with the aim of improving their biological effectiveness. In this review, we have compiled and discussed the different synthetic routes, reactivity, and pharmacological and agrochemical applications of the pyridazinone ring.

Anticancer drug waste minimization and cost-saving study by using a closed-system transfer device for chemotherapy compounding.

INTRODUCTION: There is a need for an economic evaluation of the use of closed system (CSTD) in chemotherapy compounding, especially in resource-constrained settings. OBJECTIVE: The objective of this study was to assess the cost saving of the management of cancer drug leftovers before and after introduction of CSTD associated with an extension of the beyond-use date (BUD) of cancer vials. A secondary objective was to estimate the level of minimization of drug wastage. MATERIALS AND METHODS: This was a prospective, single-center study with two periods of two months each. The cost of drugs saved by using conventional systems (syringe and needle) without a closed system in the first period was compared to the cost of drugs saved by using the CSTD Chemoclave® system in the second period. The drug waste minimization rate compared actual drug waste to potential waste in Period 2. RESULTS: In Period 1, the amount of drug saved accounted for an average of 10.3% of the amount used in milligrams and the amount of drug wasted accounted for an average of 18.7%. In period 2, these proportions were 15.2% and 6.4% respectively. The CSTD generated an extra cost of 11,962.5 USD compared to the conventional system. The drug saved cost related only to the CSTD and the acquisition cost of the CSTD was a deficit of -7,444.95 USD and the cost saved from the compounding (CSTD and syringes) was a gain of 1,722.01 USD. The waste minimization represented an average of 72.5% ± 24.4% of potential waste. CONCLUSION: The use of CSTD to extend the BUD allowed to reduce waste due to microbiological instability without adding an economic profit.

Patients' Perception of Morocco's Medicine Pricing Reform and Determinants of Their Access to Health Care and Medicine.

BACKGROUND: In 2014, the Ministry of Health of Morocco implemented a reform of medicine pricing that leads to lower prices. This reform has brought about a new method of pricing medicines and a reduction in the prices of more than 1,400 of the 5,000 medicines on the market. The objective of this study was to survey patients' perceptions of the impact of the reform on medicine prices and affordability of health care, including medicine. METHODS: Between September 2017 and September 2018, 360 patients that visited a community pharmacy in four selected areas of different socioeconomic levels were interviewed based on a questionnaire. Findings were studied through univariate and multivariate analyses. RESULTS: Three hundred patients (83%) were included given their completed questionnaire. The majority (89%) of respondents considered medicine prices as a potential barrier to access to health care. Lower medicine prices following the reform were not perceived to have actually impacted respondents' spending on health care. In some cases, care was delayed, in particular by lower-income respondents and people without insurance and health coverage. CONCLUSION: The majority of patients participating in the study did not perceive the decrease in medicine prices as sufficient. In addition, the study findings pointed to the relevance of further determinants of access to medicines, such as health insurance coverage. Patients think that the generalized third-party payment mode, which does not oblige patients to spend out of their pockets to have their treatment but rather their health insurance funds that will pay for them, provides optimal access to medicines.

Evaluation of anti-infectives prescriptions in a pediatric hemato-oncological center: A retrospective study.

INTRODUCTION: A few years after the discovery and development of anti-infectives, this therapeutic feat gave way to bacterial resistance because of the overconsumption of antibiotics, most often with unjustified prescriptions. The objective was to evaluate the compliance of the prescription of antibiotherapy in the pediatric onco-hematology unit of Rabat Children's Hospital and to determine the drug interactions. MATERIAL AND METHODS: This is a retrospective study of anti-infectives prescriptions in pediatric onco-hematology. All prescriptions containing an antibiotic or antimycotic were isolated at the end of each month for analysis according to the ANSM standard. The variables of compliance analyzed in the prescriptions were: form, indication, posology, duration of the treatment, drug interactions and number of antibiotics which were prescribed. RESULTS: The prescriptions containing at least one anti-infective were 195. All the prescriptions were in conformity with their indications; 111 (57%) of the cases were conform with respect to all criteria; 20 (12%) prescriptions were not conform in their form, 12 (6.6%) contained at least one over-dosed drug and 52 (26.7%) contained at least one under-dosed drug. A drug interaction was found in 15 (7.7%) of cases, of which 12 (6.2%) are precautions for use. A drug interaction is present in 1(6,7%) cases when a single antibiotic is prescribed against 3 (20%) cases when 4 antibiotics are prescribed. (p = 0.007). CONCLUSION: The number of non-compliances in our study was high. It would therefore be advisable to recommend the establishment of an information system to minimize the non-compliances and to ensure a training program for young doctors on international recommendations.
