Interestingly, by the addition of 50 wt% IND to the A-PentOx-A sample, the viscosity dropped by two orders of magnitude (Figure ). Additionally, the viscosity of the sample could now be monitored down to a temperature of 120 °C. By the addition of triethyl citrate (5 wt%) to the polymer-drug blends, an additional, but minor decrease in viscosity was observed. A similar trend was observed for the sample containing A-PentOzi-A as polymer excipient (Figure ).
