Table 2

Determination of terazosin in tablets by the proposed methodology and by a reported voltammetric method [8].

Claimed (mg/tablet)	Proposed methodology (mg)^a	Reported method (mg)^a	Error (%)^b	Error (%)^c
2	1.95 (±0.08)	2.07 (±0.10)	−2.5	−5.8
5	5.1 (±0.21)	5.27 (±0.37)	+2.0	−3.2

^aValues in parenthesis show the standard deviation based on three replicates.
^bError against the declared value.
^cError against the reported method.
