Hello, Atorvastatin Calcium is known as highly variable drug but when we conducted a BE study on it, the results gave low intra-subject Variability (18%) and that's inconsistent with the usual results. What could be the reason/s for this? Thank you. Edit: Category changed; see also this post #1. [Helmut] |

Hi Amira, Chance? Better assay? Design differences? Lesser within-batch variability (-ies) than in the studies you compare to? — Pass or fail! ElMaestro |
