Introduction and purpose: The pandemic of COVID-19 has induced patients to use different ways to struggle with SARS-CoV-2 infection. Amantadine has become more popular as a supportive drug in the treatment of COVID-19 symptoms. This report presents a case of a young, previously healthy woman hospitalized in the Toxicology and Cardiology Department because of acute psychosis induced by amantadine intoxication. Brief description of the state of knowledge: Several medications, including psychostimulants, antibiotics, antivirals, and antiparkinsonians can cause acute psychosis. Amantadine has primarily dopaminergic with some anticholinergic properties and is used predominantly as an adjuvant agent in the management of Parkinson's disease treatment. Psychomotor agitation, insomnia, excessive verbosity, delusions, and behavioral disturbances are typical toxic effects of amantadine primarily affecting the central nervous system presented by the patient described in this case report. Conclusions: Our case illustrates the adverse effects of amantadine on the central nervous system when given at the recommended dose to young, healthy women. Despite being rare, this induced psychosis may become more common, especially while becoming more popular as a supportive drug in COVID-19 treatment. While prescribing amantadine clinicians should be aware of the rapid onset of its psychotic complications.

Introduction and purpose: Cardiological drugs are widely used in the management of various cardiovascular diseases, such as hypertension, angina, heart failure, and arrhythmias. However, when these drugs are taken in excessive amounts or are not used as prescribed, they can become toxic and cause significant harm to the heart and other organs. Our study aims to illustrate the most frequent causes of poisoning with cardiological drugs in patients hospitalized in the toxicological and cardiological department from April 2013 to December 2021. Brief description of the state of knowledge: Poisoning with cardiological drugs is a growing concern for healthcare professionals. In 2019, cardiovascular toxins were one of the top 10 categories of poisons evaluated by medical toxicologists. Data collected from the analyzed toxicology and cardiology department include a group of 387 hospitalized patients. The largest proportion were cases intoxicated by beta-adrenoreceptor antagonists. The second most common group was poisonings by angiotensin-converting-enzyme inhibitors. A slightly lower proportion implicated poisonings caused by other, unidentified substances affecting the cardiovascular system - calcium channel blockers and other antihypertensive drugs. Conclusions: All of the data demonstrated in our study shows the importance of understanding the pharmacology, pathophysiology, and treatment strategies of poisonings caused by cardiological drugs which are one the most widely used medications worldwide.

Introduction and purpose: Drug poisoning is one of the more common reasons for patients being hospitalized in toxicology wards. The wide availability and ease of obtaining a wide variety of drugs and supplements are the cause of adverse reactions associated with their use. Increasing life expectancy and emerging chronic diseases also require the use of sometimes many drugs to control people's health. This can lead to poly-pragmasy, which is an undesirable condition and leads to poisoning. The purpose of our work is to demonstrate the most common causes of drug poisoning considering the criterion of division according to ICD-10.   Brief description of the state of knowledge: Any preparation, drug, supplement can cause negative effects on the organism. This depends on the dose, improper use, or cross-reactions of the relevant substances. The study compiled statistics on the cause of hospitalization of drug-poisoned patients based on ICD-10. 5433 patients were included in the study.   Conclusions: Our work shows that the most common causes of hospitalization due to drug poisoning are those caused by antiepileptic drugs, sedative-hypnotics and antiparkinsonism medications. The data compiled in this article agree with scientific reports from different countries compiling the most common reason for hospitalization related to drug poisoning.
