Abstract:
Pain is a leading reason for seeking medical care, necessitating accurate diagnosis and appropriate analgesic treatment. When oral administration is impractical due to nausea, vomiting, difficulty swallowing, or gastrointestinal issues, or when pain is localized, topical analgesics offer an effective alternative for managing both acute and chronic pain conditions, including osteoarthritis and neuropathic pain. These agents, such as nonsteroidal anti-inflammatory drugs, lidocaine, and capsaicin, can provide pain relief while minimizing systemic side effects. Technological advances, such as nanocarriers and microneedles, aim to improve efficacy but face challenges like cost and toxicity. Here, the authors explore the pharmacology and clinical efficacy of topical analgesics, providing recommendations for their use in pain management.

Local Anesthetics: Common Agents and Their Applications
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
