To improve the compliance of patients with type 2 diabetes there is a need to develop metformin oral dissolving tablets, which disintegrate and dissolve rapidly in the saliva. The aim of this study was to optimize the composition of metformin orodispersible tablets. The central composite design was used to establish the relation between independent variables, such as, quantity of MCC Burst, quantity of Neusillin US2, and dependent variables, such as, flowability, bulk density, tapped density, uniformity of weight, friability, tablet hardness, disintegration time, wetting time in order to obtain the optimal formulation using Response Surface Methodology. After generating the polynomial equations that relate the dependent and independent variables, the process was optimized for five responses. From the dissolution studies, it is confirmed that all formulations released more than 82% of the metformin within 3 min. It was found that the tablet containing 3% MCC Burst and 5% Neusillin US2 was a better formulation in terms of hardness (72 N), uniformity of weight (1.09%), friability (0.75%), rapid disintegration (33 sec) and drug release (95.0%) when compared with all other formulations. RezumatPentru a îmbunătăți complianța pacienților cu diabet zaharat de tip 2, este nevoie de a dezvolta comprimate cu metformin cu dizolvare orală, care se dezintegrează și se dizolvă rapid în salivă. Scopul acestui studiu a fost de a optimiza compoziția comprimatelor orodispersabile cu metformin. Am stabilit relația dintre variabile independente, cum ar fi, cantitatea de MCC Burst, cantitatea de Neusillin US2 și variabilele dependente, cum ar fi curgerea, densitatea în vrac, densitatea la tasare, uniformitatea masei, friabilitatea, rezistența la rupere a comprimatelor, timpul de dezintegrare, timpul de umectare pentru a obține formularea optimă folosind metodologia suprafeței de răspuns. După generarea ecuațiilor polinomiale care leagă variabilele dependente și independente, procesul a fost optimizat pentru cinci răspunsuri. Studiile de dizolvare confirmă că toate formulările au eliberat mai mult de 82% din metformin în 3 minute. S-a constatat că tabletele care conțin 3% MCC Burst și 5% Neusillin US2 au prezentat o formulare mai bună în ceea ce privește duritatea (72 N), uniformitatea masei (1,09%), friabilitatea (0,75%), dezintegrarea rapidă (33 sec) și eliberarea substanței active (95,0%) în comparație cu toate celelalte formulări evaluate.
