Neuromuscular blocking agents are a class of drugs that are used to induce muscle relaxation, typically during surgical procedures, mechanical ventilation, or endotracheal intubation. These agents work by interfering with the transmission of nerve impulses to the muscles, leading to paralysis. They do not have any sedative or analgesic effects, so they are usually administered…
Spasmolytics, also known as antispasmodics, are a class of drugs used to suppress muscle spasms or to decrease the tone of smooth muscle in the gastrointestinal tract, the biliary tract, or the urinary tract. These drugs are commonly used to treat conditions like irritable bowel syndrome (IBS), spastic colon, and other disorders involving smooth muscle…
Introduction Skeletal muscle relaxants are a class of medications commonly used to alleviate muscle spasms and spasticity. These drugs are often employed in the management of conditions like multiple sclerosis and cerebral palsy and after surgical procedures to facilitate intubation or mechanical ventilation. Understanding the pharmacology of skeletal muscle relaxants is crucial for healthcare professionals…
Introduction: The Importance of Preclinical Trials Preclinical trials are the cornerstone of medical research and development.
