Without reference FTIR of your drug's amorphous state, one possibly can't conclude accurately. Based on my experience, however, it looked like your sample contained crystalline drug substance, i.e. not achieved ASD.

Thank you for your answer, but how can I get the reference FTIR of my drug's amorphous state? The drug I use is valsartan and it is in crystalline state🙏

Try to melt and quench the sample to get the amorphous form.

You could also check your samples by xrpd and/or thermal studies like DSC. The best technique with the highest sensitivity would be Raman mapping, which can detect the residual crystalline drug substance in ASD below 0.01 to 0.001% (w/w).
