The stability of cefuroxime axetil in BIORACEF tablets was studied by means of long term (298 K/60% RH), intermediate (303 K/65% RH), accelerated (313 K/75% RH) and stress stability tests. Changes in the concentration of cefuroxime axetil diastereoisomers A and B and their total was determined using the RP-HPLC method, as described in a monograph of Cefuroxime axetil tablets in the British Pharmacopoeia 2003. After 2 years of storage under long term, 1 year under intermediate and 6 months under accelerated storage conditions, the preparation of BIORACEF meets the quality requirements as regards both. the active substance content and chromatographic purity. Under stress conditions the decomposition of cefuroxime axetil diastereoisomers follows the first-order reversible autocatalytic reaction with delta3-isomers of cefuroxime axetil as the main product. The kinetic parameters of the decomposition reaction were calculated and compared with analogical parameters obtained for ZINNAT tablets stored in the same conditions.

Hannover Medical School, Institute of Pharmacology, D-30625, Hannover, Germany.
Article Synopsis
- This study forecasts the consumption of the top ten antibacterial drugs in Germany until 2040, using historical prescription data and ARIMA models.
- The best model for forecasting is a simple random walk with drift (ARIMA(0,1,0)), while short-term predictions show minimal variation among complex models.
- Predictions indicate rising prescriptions for some drugs like amoxicillin, but declines for others, emphasizing the need for proactive healthcare planning to address potential shortages.
Antibiotic resistance in community-acquired urinary tract infections. Did the COVID-19 pandemic cause a change?

Division of Allergy and Immunology, Department of Pediatrics; School of Medicine, University of Kyrenia, Kyrenia, Cyprus.
Article Synopsis
- The study evaluated antimicrobial resistance rates in urine cultures before and during the COVID-19 pandemic, analyzing data from 897 patients over six years.
- E. coli and K. pneumoniae were the primary bacteria identified, with increased resistance rates for antibiotics like cefixime and ceftriaxone during the pandemic.
- Factors such as male gender and ESBL positivity were linked to higher resistance rates, indicating a notable increase in antibiotic resistance among uropathogens during this period.

Low oral bioavailability is a common feature in most drugs, including antibiotics, due to low solubility in physiological media and inadequate cell permeability, which may limit their efficacy or restrict their administration in a clinical setting. Cefuroxime is usually administered in its prodrug form, cefuroxime axetil. However, its preparation requires further reaction steps and additional metabolic pathways to be converted into its active form.

Rising bacterial resistance is a global threat, causing rising financial burdens on healthcare systems and endangering effective treatment of bacterial infections. To ensure the efficacy of antibacterial drugs, it is essential to identify the most dangerous pathogens and vulnerable antibacterial drugs. Previous research by our group suggested irrational outpatient prescribing practices in Germany, supporting a growing bacterial resistance.
