Molecular interactions of Paracetamol in solution

DOI

Active Pharmaceutical Ingredients (APIs) are frequently delivered to the patient in the solid state as part of an approved dosage form (e.g. tablets, capsules, etc.) Drug compounds tend to crystallise into different crystal forms depending on their environment, one of these influences can be the type of solvent used. We are investigating the factors that lead to the crystallisation of different forms with special interest in comparing molecular interactions in the neet amorphous state (melt) with that in solution. Paracetamol exists in at least three polymorphs (forms I, II and III) with only form III formed from the melt. In a successful proposal we are scheduled to measure paracetamol in the neat melt. We now propose to measure total neutron scattering on SANDALS for paracetamol in DMSO solution to investigate the molecular interactions leading to the crystallisation of form I
