Prescription for schizophrenia. To this?

Hi My mother is diagnosed with schizophrenia and she is refusing medication. Previously she was on medication which includes neocalm plus. I consulted a new doctor recently and sizopin 25 mg and amisulpride 100mg was prescribed. however since amisulpride 100mg was unavailable today and I'll get it tomorrow I just gave her sizopin. But she went into a very deep sleep and won't wake up even if we shake her. If this continues she won't even eat the food anymore and would doubt us that we are trying to drug her or something. Is there any alternative to this? I don't want her to be sedated like this. I just want her to gain sanity as her condition is getting worse these past few months and she is not herself. She is complaining about petrol-like smell and thinking someone is trying to kill us. Please suggest something. Should I just give her neocalm plus as it is most effective and she doesn't go in a very deep sleep.
