Contact Angle Measurement studies
Cocrystals were found to show a lowered contact angle i.e. 42° as compared to plain Carbamazepine i.e. 51°. A lowered contact angle of the cocrystals indicates the increased wetting property of cocrystal as compared to drug due to decreased hydrophobicity of drug by presence of a water-soluble hydrophilic coformer in association with the drug.
