Table 3

Results obtained in the determination of paracetamol in pharmaceutical formulations using the DP-ASV and HPLC.

Sample	Tablet label; value (mg)	HPLC value; (mg)	DP-ASV value; (mg)	Rev.	Re
Panadol Extra	500	502.75	496.86	95.2	1.2
Tiffy Dey	500	494.50	505.63	103.8	–2.3
pms-Mexcold	500	501.20	509.37	107.0	–1.6

of 3 measurements. Re(%) = 100 × (DP-ASV value − HPLC value)/HPLC value.
