Its non-clinical use has only found recent attention as a [[research chemical]] study aid.

[[Subjective effects]] include [[stimulation]], [[focus enhancement]], [[stamina enhancement]], [[increased blood pressure]], and mild [[euphoria]].

Cyclazodone is | Cyclazodone is an approximately 3x - 5x more potent N-cyclopropyl derivative of [[pemoline]]. Pemoline is considered to be [[dopamine|dopaminergic]], but its precise method of action has not been fully determined.<ref>"Cylert (Pemoline)" (PDF). FDA. December 2002.</ref> Pemoline has minimal affinity for [[noradrenaline]] receptors and thus has minimal sympathomimetic side effects compared with typical dopaminergic central nervous system stimulants such as methylphenidate and [[Isomer|dextro]]-amphetamine. | ||
According to patents filed by the inventors, cyclazodone exhibited central nervous system stimulating properties and anorexigenic properties more potent than that of pemoline and various other N-lower-alkyl-substituted pemoline derivatives. At the time cyclazodone also offered a much more favorable therapeutic index and margin of safety than pemoline and other N-lower-alkyl-substituted pemoline derivatives.<ref name="GuidicelliPatent">{{Citation | vauthors=((Guidicelli, D.

In rodents and primates, sufficiently high doses of monoamine [[releasing agent|releasing agents]] cause dopaminergic neurotoxicity, or damage to dopamine neurons, which is characterized by reduced transporter and receptor function. There is no evidence that [[releasing agent]]s are directly neurotoxic in humans. However, large doses of [[releasing agent]]s may cause indirect neurotoxicity as a result of increased oxidative stress from reactive oxygen species and autoxidation of dopamine.{{citation needed}} | In rodents and primates, sufficiently high doses of monoamine [[releasing agent|releasing agents]] cause dopaminergic neurotoxicity, or damage to dopamine neurons, which is characterized by reduced transporter and receptor function.

Addiction is a serious risk with heavy recreational stimulant use but is unlikely to arise from typical long-term medical use at therapeutic doses. Notably, the structurally related compound pemoline fails to demonstrate a potential for self-administration in primates and is considered to have reduced risk of dependence relative to those more typical dopaminergic stimulants. Caution is nonetheless advised, as with other monoamine [[releasing agent]]s. | Addiction is a serious risk with heavy recreational stimulant use but is unlikely to arise from typical long-term medical use at therapeutic doses.

Tolerance to many of the effects of cyclazodone [[Time to full tolerance | Tolerance to many of the effects of cyclazodone [[Time to full tolerance::develops with prolonged and repeated use]]. This results in users having to administer increasingly large doses to achieve the same effects. After that, it takes about [[Time to half tolerance::3 - 7 days]] for the tolerance to be reduced to half and [[Time to zero tolerance::1 - 2 weeks]] to be back at baseline (in the absence of further consumption). Cyclazodone presents cross-tolerance with [[Cross-tolerance::all [[dopamine]]rgic [[stimulant]]s]], meaning that after the consumption of cyclazodone all [[stimulant]]s will have a reduced effect. | ||
