To lay down a procedure for evaluating the growth promotion and inhibition Houses of media employed for Microbiological testing.

Antimicrobial preservatives really should not be employed in its place forever production practices or exclusively to lessen the feasible microbial inhabitants of the nonsterile merchandise or Handle the presterilization bioburden of multidose formulations all through production.
