M15 (non-specific identifier)

M15 is a non-specific identifier that can refer to several distinct entities within the pharmaceutical and medical context. It is commonly found as a pill imprint, often indicating a 15 mg dosage, on various medications. Examples include combination drugs like Diphenoxylate and Atropine, used for diarrhea and Irritable Bowel Syndrome, or single-ingredient opioids such as Oxycodone Hydrochloride and Morphine Sulfate Extended-Release. Additionally, "M15" is used as a product name for certain formulations, such as "Regrowth Labs M15," a hair regrowth treatment containing Minoxidil and Trichogen. In a different context, "M15" also designates a guideline from the International Council for Harmonisation (ICH) on Model-Informed Drug Development (MIDD), which provides principles for the use of modeling and simulation in drug development. Furthermore, "M15" appears as a prefix in clinical trial identifiers, such as "M15-954" for a study involving Venetoclax and Azacitidine, or "M15-741" for studies related to foscarbidopa/foslevodopa. Due to these multiple, unrelated meanings, "M15" does not refer to a single, specific drug.
