The present invention relates to generally to the cytoprotective activity of mixed muscarinic inhibition/PARP modulation and in particular to the use of dual inhibitors of M1 muscarinic receptor and poly(ADP-ribose) polymerase (PARP) as neuroprotective medicaments, particularly as medicaments for the prevention and/or treatment of neurological diseases. Particularly preferred compounds are condensed diazepinones, e.g. condensed benzodiazepinones such as pirenzepine or compounds which are metabolized to condensed benzodiazepinones such as olanzapine.
