Definitions
- This invention relates to a particular class of fused tricyclic heteroaromatic compounds based on a substituted isoxazole or pyrazole moiety.

- neuroleptic agents neuroleptic malignant syndrome, and disorders of hypothalamic-pituitary function such as hyperprolactinaemia and amenorrhoea.
- Dependence-inducing agents such as cocaine and amphetamine have been shown to interact with the dopamine system.
