Coke

Product Beschrijving

Coke Hydrochloride is a naturally occurring tropane alkaloid derived from the leaves of the Erythroxylum coca plant. Chemically designated as methyl $(1R,2R,3S,5S)\text{-3-(benzoyloxy)-8-methyl-8-azabicyclo[3.2.1]octane-2-carboxylate hydrochloride}$, it possesses a dual pharmacological mechanism, acting simultaneously as a local anesthetic and a potent triple monoamine reuptake inhibitor.

Chemical & Pharmacodynamic Profile

• Molecular Formula & Mass: $\text{C}_{17}\text{H}_{21}\text{NO}_4 \cdot \text{HCl}$ | 339.81 g/mol

• Peripheral Local Anesthesia: Reversibly binds to and blocks voltage-gated sodium ($\text{Na}^{+}$) channels along neuronal cell membranes. This inhibits transient sodium permeability, arresting the initiation and propagation of action potentials along sensory nerve fibers to produce localized analgesia.

• Intrinsic Vasoconstriction: Uniquely among local anesthetics, cocaine inhibits the presynaptic reuptake of norepinephrine via the norepinephrine transporter ($\text{NET}$), leading to localized $\alpha_1$-adrenergic receptor stimulation, rapid vasoconstriction, and hemostasis in highly vascularized mucosal tissue.

• Central Neurotransmission: In the central nervous system, it acts as a competitive antagonist at monoamine reuptake transporters, exhibiting highest relative affinity for the dopamine transporter ($\text{DAT}$), followed by the serotonin transporter ($\text{SERT}$) and norepinephrine transporter ($\text{NET}$). This produces an accumulation of extracellular dopamine within the mesolimbic pathway.

Clinical Indications & Analytical Applications

• Surgical Anesthesia (Rx Only): Indicated for the induction of local anesthesia of accessible mucous membranes prior to diagnostic, biopsy, or surgical interventions involving the oral cavity, larynx, and nasal cavities (e.g., rhinosurgery, sinus endoscopy).

• Analytical & Forensic Calibration: Utilized in forensic toxicological laboratories as an analytical reference material to optimize chromatographic retention times and mass spectral fragmentation patterns across gas chromatography-mass spectrometry ($\text{GC-MS}$) and high-performance liquid chromatography ($\text{HPLC}$).

• Presumptive Assay Verification: Serves as a reference control for verifying colorimetric transitions in cobalt thiocyanate (Scott test) presumptive screening protocols for tertiary amines.

Safety Disclosures & Boxed Warnings

• Abuse and Dependence: Classified as a Schedule II controlled substance under the United States Controlled Substances Act (Class A in the UK; Schedule II of the UN 1961 Single Convention) due to high liability for psychological and physiological dependence, severe misuse, and diversion.

• Cardiovascular & Systemic Toxicity: Systemic absorption carries dose-dependent risks of acute cardiovascular crisis, including severe tachycardia, malignant arterial hypertension, coronary vasospasm, fatal ventricular arrhythmias, and myocardial infarction.

• Central Nervous System Risks: Toxicity can manifest as severe agitation, acute delirium, tonic-clonic seizures, hyperthermia, and ischemic or hemorrhagic stroke.

• Institutional Governance: Procurement, custody, dispensing, and disposal require strict adherence to DEA registration mandates, secure vault storage, and perpetual inventory logging.
