Methods The fiber-optic real-time dissolution detector was used and conditions adopted for dissolution were in accordance with detecting conditions of phenporbamate tablets dissolution, and similar factor method (f2) was also used to evaluate differences of dissolution values of different manufacturer's phenporbamate tablets. Results Phenporbamate tablets was monitored at light path 0.5 mm and wave length 260 nm, and its absorbability was better with concentration at range of 20-130 μg/mL, r=0.999 9. Phenporbamate tablets from 11 different batches and 5 different manufacturers (A-E) conformed to the national drug standards (except D), but differences were found in the dissolution curves of those drugs. C1 was used as the reference preparation, only samples A, C2, C3 and E had similar dissolution process with C1's dissolution process (50 ≤ f2 ≤ 100). However, both samples B and D had clear differences in their dissolution when compared to the dissolution process of C1 (f2 < 50). Conclusion Fiber optic dissolution test system can objectively reflect the whole dissolving process of phenporbamate tablets."/> 2;QC;real time"/>
