I was wondering when exactly is an SOP needed for a USP method.
Specifically, there is a method I will use now for lidocaine assay, but it is a titration (Lidocaine HCl 2% Jelly). I have never used an in house method to run the exact USP test for a titration (not an autotitrator).
I thought we skip writing our own protocol for titration because there is no electronic instrument or software or anything like that. Is there a more specific reason? I'm asking because a director is trying to get me to write protocols for this and another titration and I know I dont have to.
I did write a protocol for an HPLClidocaine assay, but there we have the HPLC instrument.
