Buspirone was originally classified as an azaspirodecanedione, shortened to<unk>  or<unk>  due to the fact that its chemical structure contained this moiety, and other drugs with similar structures were labeled as such as well. However, despite all being called<unk> s, not all of them actually contain the<unk> canedione component, and most in fact do not or contain a variation of it. Additionally, many<unk> s are also pyrimidinylpiperazines, though again this does not apply to them all. Drugs classed as<unk> s can be identified by their -spirone or -pirone suffix.
