Abstract: The objective of the present study is the development of dispersible tablets (DTs) of an acyclovir (ACV) by quality by design (QbD) approach using maize starch (X₁), sodium starch glycolate (X₂) and magnesium stearate (X₃) as a critical quality attributes (CQA's). The design of experiment (DoE) comprising two levels, three factors (2³) is applied to optimise the combined effect of CQA's on the dependent variables such as disintegration time (Y₁), hardness (Y₂) and drug release (Y₃, Y₄ and Y₅). The centre point batch F5 has depicted the excellent properties comprising 1.20% of X₁, 4.89% of X₂ and 1% of X₃ with better Y₁ (48 ± 1.62 sec), Y₂ (138 ± 1.7 N) and Y₄ (101 ± 1.32%) as compared to the commercial formulation Zovirax©. The key effects of CQA's are observed on the Y₁ and Y₄ (p < 0.05) as compared to the Y₂ of DTs.
