Octodrine, also known as dimethylhexylamine (DMHA) and sold under the brand name Vaporpac among others, is a sympathomimetic and stimulant medication that was formerly used in the treatment of hypotension (low blood pressure).[4][5]

It has been studied in a dozen animal studies from the 1940s through the 1970s. These studies found that octodrine can increase blood pressure and cardiac output in animals. The drug was previously approved for use by the Food and Drug Administration (FDA) as an inhalant (i.e., Vaporpac and Tickle Tackle Inhaler) and in Germany as an oral medication as part of a multi-component medication (i.e., Ambredin and Ordinal), but is no longer available.[6]

DMHA has also been found as an adulterant in sports supplements and is sold online as a designer drug.[6][7] The presence of a reductive amination byproduct confirms its synthetic origin.[8]

In the United States, the FDA considers DMHA to be an unsafe ingredient in dietary supplements.[9] In 2019, the FDA issued nine warning letters to US manufacturers of dietary supplements containing DMHA as an unsafe food additive, deeming such products to be adulterated and illegal for marketing.[10]

Side effects

[edit]

Reported side effects of octodrine include hypertension, dyspnea, and hyperthermia.[5]

Pharmacology

[edit]

It is described as a sympathomimetic, vasoconstrictor, and local anesthetic.[5][11]

Pharmacokinetics

[edit]

Heptaminol is an active metabolite of octodrine.[3]

Names

[edit]

Octodrine is the generic name of the drug and its INNTooltip International Nonproprietary Name and USANTooltip United States Adopted Name.[11][4] It is also known by its former developmental code name SKF-51.[11]

As an unsafe dietary ingredient

[edit]

In the United States, DMHA is not eligible for use as a dietary ingredient, is not approved for use in manufactured foods or dietary supplements, and is not considered to be safe for human consumption (is not GRAS); in regarding DMHA as an unsafe food additive, the FDA has warned manufacturers that dietary supplements containing DMHA are adulterated and illegal for marketing.[9][10]
