1. Introduction/Overview The modulation of skeletal muscle tone is a critical therapeutic objective in numerous clinical conditions, ranging from acute surgical paralysis to chronic management of spasticity. Skeletal muscle relaxants encompass a diverse group of pharmacological agents that reduce muscle tone and contractility through distinct mechanisms. The preclinical and clinical evaluation of these agents necessitates … Read more
Introduction/Overview The clinical application of local anesthetics represents a cornerstone of modern medical practice, enabling painless surgical, diagnostic, and therapeutic procedures. The evaluation of local anesthetic activity, specifically for surface (topical) and infiltration anesthesia, is a fundamental pharmacological discipline. This evaluation encompasses not only the assessment of a drug’s ability to produce a reversible blockade … Read more
1. Introduction/Overview The study of pharmacological agents that alter pupillary size—miotics (constrictors) and mydriatics (dilators)—constitutes a fundamental pillar of ophthalmic pharmacology. These drugs exert their effects primarily by modulating the autonomic innervation of the iris muscles: the sphincter pupillae (parasympathetically controlled) and the dilator pupillae (sympathetically controlled). Understanding their mechanisms, kinetics, and clinical applications is … Read more
Introduction/Overview The evaluation of renal function and the pharmacological modulation of urine output constitute a fundamental area of experimental and clinical pharmacology. Among the various in vivo assays developed, the method described by Lipschitz, Hadidian, and Kerpesar in 1943 remains a cornerstone for the preliminary screening of substances for diuretic or antidiuretic activity. This bioassay … Read more
