Abstract:
Xylazine, an alpha-2 adrenergic agonist used as a veterinary sedative, has been detected in the illicit drug supply with increasing frequency and is thought to contribute to opioid-related overdose and fatality. Several mass spectrometry-based methods for the detection of xylazine have been described but very few clinical laboratories routinely perform testing and point of care assays for acute xylazine toxicity are not currently available. The development of new methods for timely, cost-effective detection of xylazine is a priority to reduce harms associated with this drug.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

Analysis Methods of Pharmacokinetic Data: Model and Model-Independent Approaches
The model approach uses mathematical models to describe changes in drug concentration over time. Pharmacokinetic models help characterize drug behavior in patients, predict drug concentration in the body fluids, calculate optimum dosage regimens, and evaluate the risk of toxicity. However, ensuring that the model fits the experimental data accurately...
