Dimethocaine (DMC, larocaine): A Synthetic Cocaine Derivative

Introduction

Enter the realm of Dimethocaine (DMC, larocaine) – a compound with a structure resembling procaine, known for its stimulating effects akin to cocaine. Often referred to as DMC or larocaine, this compound holds a unique position as a legal replacement for cocaine in certain countries, acknowledged by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA). Let’s explore further into what dimethocaine offers and how it’s used.

Experience the Potential: Dimethocaine, also known as DMC or Larocaine, mirrors cocaine’s actions as a local anesthetic. With a potency akin to cocaine, it completely halts dopamine uptake in rat striatal synaptosomes, closely mirroring cocaine’s impact. Demonstrating a dose-dependent substitution for cocaine in drug discrimination tests in rats and rhesus monkeys, this product is exclusively meant for forensic and research applications.

Understanding Dimethocaine

Dimethocaine (DMC, larocaine), an ester of 4-aminobenzoic acid, shares structural similarities with procaine. This compound presents itself as a powder at room temperature, eliciting a stimulation akin to cocaine. It influences the brain’s reward pathway, sparking tendencies toward addiction.

Legality and Purpose

Despite its resemblance to cocaine, Dimethocaine (DMC, larocaine) serves as a legal alternative and is categorized by EMCDDA as a “synthetic cocaine derivative.” Originally utilized as an anesthetic in dentistry, ophthalmology, and otolaryngology during the 1930s, it is now primarily intended for forensic and research applications due to its potential for abuse.

Exploring Resiniferatoxin’s Biological Activity

Shifting focus to resiniferatoxin, a compound with astounding heat units, ranking at 16 billion on the Scoville scale, surpassing the heat intensity of pure capsaicin by 500 to 1000 times. This compound triggers the transient vanilloid receptor 1 in particular sensory neurons that play a role in transmitting physical pain, known as nociception.

Mechanism of Action

Resiniferatoxin’s interaction with TRPV1, an ion channel on sensory neuron membranes, induces cation permeability, notably calcium influx. This rush of ions causes the neurons to depolarize, imitating signals similar to those of tissue damage or a burning sensation. Subsequently, desensitization and analgesia follow, partly due to nerve ending demise from calcium overload.

The Historical Context of Dimethocaine

Originally synthesized by Hoffmann-La Roche in 1930 and marketed as “larocaine,” dimethocaine gained traction in the US during the 1930s for its anesthetic properties, akin to cocaine and procaine. However, its psychoactive effects and addiction potential led to its removal from the market in the 1940s. Presently, it’s unlawfully employed for its psychoactive effects, sold as a surrogate for cocaine, bypassing legal restrictions.
