What type of information is NOT included in The Merck Index?

The Merck Index is a comprehensive reference work that provides a wealth of information relevant to pharmaceuticals, chemicals, and biological substances. It includes detailed entries on chemical attributes, such as molecular structure, physical properties, and various chemical reactions, which are essential for understanding the characteristics of different compounds. It also covers medications, offering insights into their formulations, usage, and pharmacological profiles. Biological characteristics, which include information about biological activity and toxicology, are also detailed within its entries, providing a complete picture of substances.

However, the prescribing habits of practitioners are clinical practices and behaviors that vary widely and are typically not documented in The Merck Index. This type of information is more relevant to clinical studies, healthcare guidelines, or specific pharmacotherapy textbooks. Therefore, selecting this option highlights a clear distinction between the scientific focus of The Merck Index and the clinical practices that pertain to medication prescribers.
