1,3-dimethylamylamine or 4-methylhexane-2-amine (DMAA)

1,3-dimethylamylamine or 4-methylhexane-2-amine (DMAA) interim decision

Scheduling proposal

The medicines scheduling delegate initiated a proposal to include of 1,3-dimethylamylamine (DMAA) in Schedule 9 of the Standard for the Uniform Scheduling of Medicines and Poisons (SUSMP). This was in response to New Zealand's temporary Class Drug Notice of 8 March 2012 advising that DMAA would be classified as a temporary class drug (equivalent to Schedule 9). New Zealand's temporary prohibition of DMAA came into effect on 9 April 2012.

Scheduling status

DMAA is not specifically scheduled in Australia.

Pre-meeting submissions

Six pre-meeting submissions were received. One submission supported the proposed prohibition, noting that DMAA is addictive. The other five submissions did not support the prohibition, indicating that DMAA is safe, effective and has no negative health effects. One submission also suggested that DMAA be regulated rather prohibited.

The redacted public submissions are available at Public submissions on DMAA referred to ACMS#6 (July 2012).

Advisory Committee on Medicines Scheduling (ACMS) discussion

The Committee considered the referral from the medicines scheduling delegate to include 1,3-dimethylamine or 4-methylhexane-2-amine (DMAA) in Schedule 9 of the Standard for the Uniform Scheduling of Medicines and Poisons.

Members deliberated over the proposed scheduling of DMAA and whether it should be included in Schedule 4, Schedule 9 or Appendix C. Members noted that:

  • There is inadequate evidence to suggest DMAA's toxicological and pharmacological properties warrant a Schedule 9 listing.
  • DMAA is not listed in either Schedule IV to the United Nations Convention on Narcotic Drugs, 1961 or in Schedule 1 to the United Nations Convention on Psychotropic Substances, 1971.
  • There is a lack of supporting evidence to reach the conclusion that DMAA needs the same level of control as amphetamine.
  • DMAA's toxicological properties meet the Appendix C scheduling criteria.

Members agreed that DMAA should be included in Appendix C for the following reasons:

  • DMAA has no current accepted therapeutic use.
  • DMAA has a stimulant effect which can induce a psychoactive effect.
  • DMAA is being actively promoted and used as a party drug as well as a sports supplement.
  • There is no real evidence of dependence on DMAA.
  • There are a number of significant adverse events including cardiac, nervous and psychiatric disorders that have been reported with use of DMAA including cerebral haemorrhage and heart attacks.
  • The potential for misuse and abuse is high.

Delegate's consideration

The delegate considered the following in regards to this proposal:

  • New Zealand's temporary Class Notice;
  • International scheduling decisions, including the United States FDA, Canada and United Kingdom;
  • public submissions received;
  • ACMS advice;
  • section 52E of the Therapeutic Goods Act 1989;
  • scheduling factors1;
  • other relevant information.

1Scheduling Policy Framework for Medicines and Chemicals

Delegate's interim decision

The medicines scheduling delegate has made an interim decision to include 1,3-dimethylamylamine in Schedule 9 of the SUSMP. The delegate has also agreed to the inclusion of a cross reference to the index from DMAA to 1,3-dimethylamylamine and 4-methylhexane-2-amine.

The proposed implementation date for this decision is 1 August 2012.

The delegate decided that the relevant matters under section 52E(1) of the Therapeutic Goods Act 1989 include (a) risks and benefits of the use of a substance, (b) the purposes for which a substance is to be used and the extent of use of a substance, (c) the toxicity of a substance, and (e) the potential for abuse of a substance.

In response to safety concerns surrounding the abuse of DMAA and following advice from the ACMS and public consultation, the delegate has made an interim decision to include DMAA in Schedule 9 of the SUSMP. The decision to introduce broader controls on DMAA included the following reasons:

  • there are no current approved therapeutic uses for DMAA;
  • there are no benefits but there are significant risks;
  • there are risks due to DMAA's toxicity;
  • DMAA presents a high risk of abuse, misuse and illicit use;
  • reports of adverse events including high blood pressure, psychiatric disorders, cerebral haemorrhage and stroke;
  • an absence of studies demonstrating the long-term safety of DMAA; and
  • the wide variability in the potency of the different doses of DMAA.
