DL-Penicillamine is a potent chelating agent primarily used in the treatment of Wilson’s disease, rheumatoid arthritis, and cystinuria. As a derivative of penicillin, it exhibits remarkable efficacy in binding heavy metals, particularly copper, thus aiding in their excretion from the body. This pharmaceutical compound, available in various forms such as tablets and capsules, functions by disrupting the formation of copper-dependent enzymes, consequently reducing copper levels in tissues and preventing associated toxicities. DL-Penicillamine is known for its ability to alleviate symptoms and improve the quality of life for patients suffering from conditions characterized by copper accumulation or abnormal cystine metabolism.
