What should be added before using a suppository mold?

Using a lubricant before using a suppository mold is essential for several reasons. First, lubricants facilitate the smooth insertion of the suppository into the mold, which helps in achieving a well-formed product. This is especially important when the suppository base is firm or has a high melting point, as a lubricant minimizes friction and makes the process easier.

Additionally, using a lubricant can help prevent the suppository from sticking to the mold, which can lead to deformities or breakage of the suppository during removal. This is crucial for maintaining the integrity and intended shape of the dosage form.

While other options like preservatives, flavoring agents, and buffering agents are relevant in different contexts of pharmaceutical formulation, they are not directly associated with the immediate process of utilizing a suppository mold. Therefore, the application of a lubricant is specifically important in this scenario.
