Table 3.

Data on the assay of chloroquine, and hydroxychloroquine extemporaneous suspensions (25 mg/ml) after weak centrifugation (3000 rpm, 25 °C, 5 min). The extemporaneous suspensions were obtained dispersing the crushed tablets in different aqueous vehicles (i.e., purified water, CMC, FOSP). The data are expressed as a mean percentage and relative standard deviation (RSD%) of three batches of suspension.

Vehicle	Drug assay (%)		RSD (%)
	Chloroquine	Hydroxychloroquine	Chloroquine	Hydroxychloroquine
Water	101.8	102.8	5.0	3.3
CMC	102.0	98.6	3.2	5.3
FOSP	103.6	98.7	3.9	3.8
