Abstract: The present invention provides novel solvated forms of darunavir and processes for their preparation. The present invention also provides novel processes for the preparation of darunavir amorphous form and pharmaceutical compositions comprising it. Thus, for example, darunavir 2-methyl-2-butanol solvate was dissolved in methylene dichloride, distilled under vacuum at 45° C. to obtain a residue, cyclohexane was added to the residue and stirred for 30 hours at 20 to 25° C., and the separated solid was filtered, washed with cyclohexane and dried under vacuum at 50° C. for 12 hours to yield darunavir amorphous form.
