Background And Objectives: Several mechanisms have been proposed for the sudden unexpected death in epilepsy patients, such as cardiac arrhythmias, a decrease in heart rate variability and the use of anti-epileptic drugs (AEDs). Although carbamazepine is commonly used as an AED, the exact working mechanism of this drug as well as its effect on the heart are not completely understood. The aim of this study was to determine whether chronic carbamazepine therapy in patients with focal seizures and impaired awareness has an effect on the electrocardiogram (ECG).
Subjects And Methods: This cross-sectional study included 36 patients with focal seizures and impaired awareness treated for 12-32 months with carbamazepine monotherapy and 38 healthy volunteers. A 5-min modified three-electrode chest lead ECG with lead II configuration was recorded using LabChart 7 ECG software module at 1000-Hz sampling frequency. All data analysis was performed using custom-made Matlab 2015b scripts. ECGs of patients and controls were compared with respect to heart rate, time intervals and measures of short- and long-term variation.
Results: There were no significant differences in heart rate and ECG time intervals between the patient and control groups. Measures on short- and long-term variability also did not show any significant group differences.
Conclusion: Our study shows that chronic use of carbamazepine as monotherapy does not have any significant effects on ECG time intervals or measures of short- and long-term variability.

Background: Hypertension, which affects 1.28 billion people globally aged 30 to 79, is characterized by continuously high blood pressure (140/90 or more) and raises the risk of premature death. Losartan, an angiotensin receptor blocker (ARB), is suggested for patients under the age of 55 who cannot take ACE inhibitors as a first treatment option.

Trigeminal neuralgia (TN) is chronic pain caused by damage to the somatosensorial system on the trigeminal nerve or its branches, which involves peripheral and central dysfunction pain pathways. Trigeminal pain triggers disruptive pain in regions of the face, including within and around the mouth. Besides clinical experiences, translating the language of suffering into scientific terminology presents substantial challenges.

The objective of this study is to evaluate the anticonvulsant efficacy of carbamazepine (CBZ) following acute and chronic administration across four treatment protocols in a murine model of maximal electroshock-induced seizures. A single dose of the drug was utilized as a control. The neurotoxic effects were evaluated in the chimney test and the passive avoidance task.

Topiramate (TPM) is a broad-spectrum antiepileptic drug (AED) commonly prescribed for approved and off-label uses. Routine monitoring is suggested for clinical usage of TPM in special population due to its broad side effect profile. Therefore, it is crucial to further explore its pharmacokinetic characteristics.

Experimental animal models are crucial for elucidating the pathophysiology of liver injuries and for assessing new hepatoprotective agents. Drugs and chemicals such as acetaminophen, isoniazid, valproic acid, ethanol, carbon tetrachloride (CCl), dimethylnitrosamine (DMN), and thioacetamide (TAA) are metabolized by the CYP2E1 enzyme, producing hepatotoxic metabolites that lead to both acute and chronic liver injuries. In experimental settings, acetaminophen (centrilobular necrosis), carbamazepine (centrilobular necrosis and inflammation), sodium valproate (necrosis, hydropic degeneration and mild inflammation), methotrexate (sinusoidal congestion and inflammation), and TAA (centrilobular necrosis and inflammation) are commonly used to induce various types of acute liver injuries.
