Diphenylpropylamine

Dipipanone-containing Diconal tablets are indicated for moderate to severe pain in medical and surgical conditions where morphine may be indicated1 and prolonged use of Diconal may lead to drug dependence (addiction), even at therapeutic doses1. It is used for severe or acute pain when morphine is contraindicated, including allergy. Structurally, it closely resembles methadone but has a piperidine ring in place of methadone’s dimethylamino group.2 It is often combined with cyclizine, which potentiates its effects, and has morphine-equivalent potency.

Harm Potential

Addiction & Dependence

Psychological

High

When taken orally as indicated for pain, the abuse potential and euphoric potential is similar to that of morphine. The substance is classified as habit-forming and prescription is discouraged due to perceived risk of abuse.

Physical

High

As an opioid with addiction potential comparable to morphine, physical dependence is expected to develop with regular use, following typical opioid dependence patterns.

Toxicity

Lethal Dosage

In the UK from the late 1970s through the early 1980s, misuse of this preparation was linked to many deaths, especially when it was injected. Insoluble tablet binders can cause severe injury or death if injected.

Vascular

Injection of tablet preparations can cause serious vascular injury or death due to insoluble binders present in the tablets; this risk is specific to intravenous misuse and does not apply to oral administration as prescribed.

History & Culture

United Kingdom oral formulations and specialist clinics

During the 1970s and 1980s, dipipanone was also available in the United Kingdom as a 10 mg/5 mL oral mixture without cyclizine. This formulation was rare and was generally used in drug trials and specialist Diconal addiction clinics.
