Hi, Can any body comment on using of same formula ( without affecting the proportion of each excipient) for an oral solution solutions of same product but different strengths. For instance; extrapolating the formulation of piperazine citrate 700mg/5ml from the formula of piperazine citrate 500mg/5ml. And what is the regulatory requirements for such products. Thank you
