The glomerular filtration rate (GFR), according to which the drug dose for patients with chronic kidney disease (CKD) is adjusted, is computed with estimators (eGFR) that are developed specifically for CKD. These particular types of estimators are also used in population pharmacokinetic (pop PK) modelling in drug development. Similar approaches without scientific validation have been proposed for patients with acute kidney injury (AKI), yet it is uncertain which specific eGFR should be used for drug dosing or in pop PK models in patients with AKI.

Article Synopsis
  • - Dabigatran etexilate is an anticoagulant used to prevent strokes and thromboembolic events, but its interactions with other drugs are still unclear.
  • - A 72-year-old male patient with heart and kidney issues experienced an overdose of dabigatran while taking it alongside ranolazine, leading to dangerously high INR levels.
  • - After stopping dabigatran, the patient's INR and kidney function improved, highlighting the need for careful monitoring and dosage adjustments for patients with renal failure using these medications.

Irrational use of nonsteroidal anti-inflammatory drugs (NSAIDs) is the main cause of adverse effects-associated hospitalizations among all medication groups leading to extremely increased costs for health care. Pharmacoepidemiological studies can partly reveal such issues and encourage further decisions. Therefore, the aim of our study was to evaluate the utilization of non-opioid analgesics (ATC classification N02B and M01A) in Lithuania, and to compare it with that of other Baltic and Scandinavian countries in terms of compliance to the WHO pain treatment guidelines and the EMA safety recommendations on NSAID use.

Background And Objective: The aim of this randomized, single dose, two-period crossover study with two weeks wash-out period was the demonstration of bioequivalence of two recombinant human granulocyte colony-stimulating factor (rG-CSF) formulations after subcutaneous administration of 300μg comparing their pharmacokinetic (primary endpoints AUC0-24, AUC0-∞ and Cmax) and pharmacodynamic (primary endpoints ANC AUC0-72, ANC AUC0-∞ and ANCmax) profiles in healthy male subjects.

Materials And Methods: A total of 36 (23.0±6.

The safety profile of paracetamol and simvastatin is sufficiently well known, although no interactions between these two medicinal products have been described in the scientific literature so far. A 66-year-old female patient who experienced myocardial infarction and underwent coronary artery bypass grafting 9 years ago was taking simvastatin at a daily dose of 10 mg. Liver enzyme tests were carried out regularly, and their results were always normal.

Mirtazapine is an established antidepressant with well-documented efficacy demonstrated in controlled clinical trials. However, the gap between the results obtained in controlled clinical trials and everyday clinical practice exists. Therefore, the importance of naturalistic studies in psychiatry is becoming recognized.

A 70-year-old patient treated with oxcarbazepine experienced severe hyponatremia. The patient used oxcarbazepine (600 mg twice a day) concomitantly with diuretics (torasemide 10 mg and indapamide 1.25 mg once per day), perindopril, an angiotensin-converting enzyme inhibitor, and amlodipine, a Ca(2+) channel blocker.

Nonsteroidal anti-inflammatory agents are used more than 100 years. Most of them can cause undesirable effects on gastrointestinal tract: ulceration, bleeding and perforation of stomach and duodenum. Gastrointestinal toxicity is diminished when selective cyclooxygenase-2 inhibitors are used.

Doctors prescribing some medications together are often using unreasonable drug combinations. The rationality of prescribing the medications by means of case-records and computerized data base of the state sicknes fund was investigated. The article addresses the most common cases of unreasonable use of medications, which could be divided into five subgroups: 1) Prescribing drug combinations, that increase the possibility of side-effects; 2) Prescribing some medications, that may suppress the effects of each other together; 3) Using medications, that belong to the same group together; 4) Prescribing the medications either without indication or out of indication; 5) Other cases of the unreasonable medication use.
