Using SEM to design a new generation of drug forms

Abstract

Detailed study and understanding of the processes that occur during the cooling and subsequent annealing of frozen solutions of drugs in two-component systems of low boiling point liquids and water with clathrate formation requires the active involvement of scanning electron microscopy (SEM) to select the optimum conditions for freeze drying and comparative analysis of samples, forms of dosage, and initial substances. A new way of creating ultrafine forms of drugs and pharmaceutical compositions by freeze drying that can easily be extended to almost all modern low-dosage drugs to improve their pharmacokinetic profile and technological properties is developed.
