Inactive Ingredient Library

185 compounds

An inactive ingredient is any component of a drug product other than the active ingredient. Inactive ingredients are added during the manufacturing process of pharmaceutical products such as tablets, capsules, suppositories, and injections. In new drug development, once an inactive ingredient has appeared in an approved drug product for a particular route of administration, the inactive ingredient is not considered new and may require a less extensive review the next time it is included in a new drug product.

MCE offers a unique collection of 185 inactive ingredients, which only contain inactive ingredients of the final dosage forms of the drug. MCE Inactive Ingredient library is a powerful tool for aiding in the development of the drug and saving unnecessary time.

Rhodizonic acid disodium can also be used for real-time visualization of the dynamic process of lead sequestration in the plant rhizosphere and evaluation of the effects of environmental factors such as soil type on the stability of lead-sequestering structures .
