Results: Crushing strength values of the drug samples ranged between 6 and 16 kp while
the disintegration times were between 7.43 and 10.40 min (for uncoated tablets) and
3.25–37.32 min (for coated tablets). Friability values were less than 1% and the melting
points of recrystallized ibuprofen from the samples ranged from 73.5 to 76.0 C. The
amount of ibuprofen released within 1 h ranged between 18% and 102% and two brands
failed the content of active ingredient in the UV method of assay while all the brands
passed the test using HPLC.
