STUDY ON THE EFFECTS OF VARIOUS DISINTEGRANTS ON AMOXICILLIN TRIHYDRATE DISPERSIBLE TABLETS
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2012, Vol 3, Issue 5
Abstract
The objective of this work was to develop a formulation of amoxicillin trihydrate dispersible tablets of 320mg in a low production value, using cheap amoxicillin trihydrate raw materials available in the market, with direct compression or wet granulation method. Amoxicillin trihydrate is a semisynthetic antibiotic, an analogue of ampicillin with a broad spectrum of bactericidal activity against gram +ve and gram –ve organism. Dispersible tablets are uncoated or film coated tablets intended to be dispersed in water before administration giving a homogeneous dispersion. The WHO prefers dispersible dosage form for the elderly and paediatric patients due to its ease in the administration. Amoxicillin trihydrate dispersible tablet was manufactured with the different disintegrants such as maize starch, crospovidone, croscarmellose, sodium starch glycolate, croscarmellose. The powder blend was evaluated for angle of repose, bulk density, tapped density, compressibility index and hausner’s ratio. After compression the tablets were subjected to weight variation, %drug content, buoyancy studies and in-vitro release studies. The wet granulation was excluded from the formulation due to its high cost if production, direct compression was selected due to its low cost and ease of production. The optimized formulation F10 had showed 99.11% of drug release in 40 min and disintegration of tablet was 25 seconds. The result of FTIR analysis of pure drug alone and drug with excipients there was not showed any physical and chemical interaction. F10 had undergone DTA, which shows the thermal stability of the formulation. The stability studies of optimized formulation F10 at 30◦C / 65%RH, 40◦C / 75%RH did not show any change in tested parameters and release.
