This study was conducted to evaluate the effect of ultrasound application on the surface microhardness (VHN) and diametral tensile strength (DTS) of three high viscous glass-ionomer restorative materials (HVGIRMs). For each test (VHN and DTS), a total of 180 specimens were prepared from three HVGIRMs (Ketac-Molar Aplicap, Fuji IX GP Fast, and ChemFil Rock). Specimens of each material (n = 60) were further subdivided into three subgroups (n = 20) according to the setting modality whether ultrasound (20 or 40 s) was applied during setting or not (control). Specimens within each subgroup were then equally divided (n = 10) and tested at 24 h or 28 days. For the VHN measurement, five indentations, with a 200 g load and a dwell time for 20 s, were made on the top surface of each specimen. The DTS test was done using Lloyd Testing machine at a cross-head speed of 0.5 mm/min. Ultrasound application had no significant effect on the VHN. Fuji IX GP Fast revealed the highest VHN value, followed by Ketac-Molar Aplicap, and the least was recorded for ChemFil Rock. Fuji IX GP Fast and Ketac-Molar Aplicap VHN values were significantly increased by time. ChemFil Rock recorded the highest DTS value at 24 h and was the only material that showed significant improvement with both US application times. However, this improvement did not sustain till 28 days. The ultrasound did not enhance the surface microhardness, but its positive effect on the diametral tensile strength values was material and time dependent.

PURPOSE: To evaluate the physicochemical characteristics of clindamycin HCl in a complex form (resinate) with ion exchange resin (IER) (Amberlite IRP69).

METHODS: Drug-resin complex was prepared by simple aqueous binding method. Drug binding study was carried out at different drug and resin concentrations. Several physicochemical characterization studies were conducted to evaluate the resinate complex. These studies included flow properties, in vitro drug release in SGF and SIF, DSC, TGA, mass spectroscopy and XPRD evaluations. In addition, stability study of resinate complex was conducted at 25 and 40 °C for up to 1 month.

RESULTS: Clindamycin and Amberlite IRP69 have formed a complex (resinate) and have shown good flow properties, good thermal properties and chemical stability (short term over 4 weeks) at 25 and 40 °C. Clindamycin release profiles from resinate in SGF and SIF have shown immediate release characteristics and release in simulated saliva has shown dependence on water volume.

CONCLUSION: The clindamycin stable complex with IER (Amberlite IRP69) has the potential for further development as a compatible pediatric liquid formulation (suspension) or a fast disintegrating tablet.
