Fig. (1) Performance frontier for sucrose and titratable acidty. Medicines 14 (Clavulin 125mg), 15 (Clavulin 250mg), 16 (Clavulin BD 200mg), 17 (Clavulin BD 400mg) and 18 (Clavulin ES 600mg) are close to the frontier because their low levels of sucrose and titratable acidity, while medicines 23 (Klaricid^® 25mg/5mL), 24 (Klaricid^® 50mg/5mL) and 27 (Zinnat^® 250mg/5mL) presented the worst performance because of their high levels of sucrose and titratable acidity.
