The present invention provides a novel cyclohexane solvate form of lopinavir, and a process for its preparation thereof. The present invention also provides a novel desolvated crystalline form of lopinavir, process for its preparation and to pharmaceutical composition containing it. Thus, for example, lopinavir cyclohexane solvate was heated at 100° C. for 10 hours to give lopinavir desolvated crystalline form H1.
