Impact Of Defensive Covering Of Anti-Inflamatory Medicine Tablets With Acrylatemethacrylate Copolymers On Tablet Crumbling Times And Disintegration Rates
Tablets of headache medicine (a dampness degradable medication) have been film covered with two undifferentiated from Eudragit RL and RS copolymers assigned here as An and B which vary just in their cation content in the proportion 2:1 (A:B). An, is in this manner more hydrophilic than B. The tablets were film covered with ethanol arrangements of these two polymers. Film covering with either An or B fundamentally decreased the dampness take-up possibilities of the tablets however caused an expansion in the breaking down occasions of the tablets and hindered disintegration rates. The mean deterioration times were 0.5±0.1 min (uncoated tablets), 16±2.5 min (tablets covered with An) and 115±3.6 min (tablets covered with B). The relating disintegration rates % h - 1 were 28.3 for uncoated, 16.6, covered with An and 14.8, covered with B, separately. Subsequently, covering with polymer B impressively impeded the crumbling and disintegration properties of the tablets.
