Abstract
AbstractAcetaminophen tablets containing minimum amount of excipients and varying amounts of cross linked polyvinyl pyrrolidone were prepared under accurately controlled conditions of compression speed and pressure. The disintegration time, dissolution rate, crushing force, friability as well as effect of temperature and humidity on these parameters during storage were determined. Increasing proportions of the cross linked polymer (1-10%) did not influence crushing force or friability but significantly decreased disintegration and dissolution time. Satishctory tablets with desired properties were obtained by incorporation of optimum quantity of crospovidone. Storage of acetaminophen tablets at room temperature and humidity for a period of 4 weeks did not alter any of the physical properties tested weekly. However the combined effect of elevated temperature and humidity on tablet properties, especially on the dissolution time was significant. The influence of incorporation of equal amounts of crospovidone ...
