Preservatives found in pharmaceutical products are a group of chemical substances added in multidose solutions to primarily reduce the risk of microbial contamination. Benzalkonium chloride, Polyquad, SofZia, and Purite are the common preservatives especially used in anti glaucoma agents. While SofZia and Purite are new preservatives that have been called vanishing preservatives, because they convert to nontoxic substances once in the eye, Benzalkonium chloride, on the other hand is the most common ophthalmic preservative.
