Dear Hariemmadi, The maximum ISCV observed in literature is approximately 12 % for cmax. Based on that 12 subjects are sufficient to prove bioequivalence with 80 % power. However considering the dropouts better to enroll two extra subjects. — Thanks and regards Ashutosh Kumar Yadav M.Pharm (Pharmacology) Mob. No. +91-079-9904516032 |

Hi Hariemmadi, According to the Intrasubject CV twelve volunteers are ok. But you have to look after the ratio's (point estimate) also. Considering the ratios also, we have to decide the sample size. For suppose if the ratios you are getting around 90 or 110 then the sample size will be more. So be caution regarding this. Thank you. — Regards, MGR |
