  • Publication number: 20250242033
    Abstract: Novel Stannic protoporfin compositions exhibiting high purity and other characteristics, including a novel solubility profile and visual indicators suggesting increase pharmacological activity, including enhanced antiviral activity. Also disclosed are novel processes for making Stannic protoporfin according to a process that requires fewer steps than known processes. Methods of treating patients before a scheduled insult such as surgy by administering a combination of stannic protoporfin and iron sucrose are provided. The present methods provide protection to photosensitive patients and those susceptible to post-operative complications.
