The disintegrant potential of native starches of five new cassava ( Manihot esculenta  Crantz.) varieties developed by the Crops Research Institute of Ghana (CRIG) was studied in paracetamol tablet formulations. The yield of the starches ranged from 8.0 to 26.7%. The starches were basic (pH: 8.1–9.9), with satisfactory moisture content (≤15%), swelling capacity (≥20%), ash values (<1%), flow properties, and negligible toxic metal ion content, and compatible with the drug. The tensile strength ( T   s  ), crushing strength ( C   s  ), and friability ( F   t  ) of tablets containing 5–10% w/w of the cassava starches were similar ( p  > 0.05) to those containing maize starch BP. The disintegration times of the tablets decreased with increase in concentration of the cassava starches. The tablets passed the disintegration test ( D   T   ≤ 15 min) and exhibited faster disintegration times ( p  > 0.05) than those containing maize starch BP. The disintegration efficiency ratio (DER) and the disintegration parameter DER  c   of the tablets showed that cassava starches V20, V40, and V50 had better disintegrant activity than maize starch BP. The tablets passed the dissolution test for immediate release tablets (≥70% release in 45 min) with dissolution rates similar to those containing maize starch BP.
