Introduced in the 1980s, isoflurane quickly gained popularity due to its favorable pharmacokinetic properties. Its low solubility in blood means that it can be delivered to the brain quickly, facilitating a faster onset of anesthesia. This characteristic is particularly beneficial in surgical settings where time is of the essence. Additionally, the agent’s moderate potency allows for precise control over anesthetic depth, which is crucial during complex surgical procedures.
Pentoxifylline is a methylxanthine derivative that has been widely used in the medical field since its introduction in the late 20th century. Its primary mechanism of action involves the improvement of blood flow by reducing the viscosity of blood, which enhances the flexibility of red blood cells. This unique property allows it to be effective in various clinical applications, particularly in the treatment of circulatory disorders.
