Succinic Acid
Excipient (pharmacologically inactive substance)
What is Succinic Acid?
There has been some concern over the use of phthalates in medications, total exposure to phthalates, and possible toxicity, although specific research is lacking. The FDA is aware of the use of phthalates in enzymes. Phthalates are included in its list of inactive ingredients for FDA-approved drugs.[2] Phthalates are known to be excreted in the urine, although data on accumulation is not known.
