Description
Summary:A primary objective of this review is to summarize the evidence-based pharmacological applications of capsaicin, particularly its use to manage pain and treat various health conditions. A second goal of the review is to research how recent technological advances are improving the bioavailability and therapeutic index of capsaicin, as well as the development of novel capsaicin-mimetics that are able to enhance therapeutic responses in various human diseases. In the review, numerous human clinical trials and preclinical studies are examined to determine how effective, safe, and optimal dosages of capsaicin can be used in pain management and therapeutic applications. Furthermore, it discusses capsaicin's mechanisms of action, specifically its interactions with the transient receptor potential vanilloid 1 (TRPV1) channel. As a result of this review, the potential of nanotechnology systems for bypassing the limits of capsaicin's pungency is discussed. The review takes into account individual factors such as pain tolerance and skin sensitivity. For topical applications, capsaicin is typically used in concentrations ranging from 0.025% to 0.1%, with higher concentrations being used under medical supervision for neuropathic pain. The formulation can come in the form of creams, gels, or patches, which provide sustained release over the course of time. A condition such as arthritis or neuropathy can be relieved with capsaicin as it depletes substance P from nerves. Neuropathy and osteoarthritis as well as musculoskeletal disorders have been treated successfully with this herbal medicine. A major mechanism through which capsaicin relieves pain is through activating TRPV1 channels, which induce calcium influx and neurotransmitter release. Additionally, it affects the transcription of genes related to pain modulation and inflammation, particularly when disease conditions or stress are present. There have been recent developments in technology to reduce capsaicin's pungency and improve its bioavailability, including nanotechnology. It is proven that capsaicin is effective in pain management as well as a variety of therapeutic conditions because of its ability to deplete substance P and desensitize nerve endings. Although capsaicin is highly pungent and associated with discomfort, advancements in delivery technologies and the development of capsaicin-mimetics promise improved therapeutic outcomes. There is a great deal of complexity in the pharmacological action of capsa
