    State Liquid Absorption Rapidly absorbed.

    Description

    A clear, colorless liquid rapidly absorbed from the gastrointestinal tract and distributed throughout the body. It has bactericidal activity and is used often as a topical disinfectant. It is widely used as a solvent and preservative in pharmaceutical preparations as well as serving as the primary ingredient in alcoholic beverages.

    Mechanism of Action

    Ethanol affects the brain’s neurons in several ways. It alters their membranes as well as their ion channels, enzymes, and receptors. Alcohol also binds directly to the receptors for acetylcholine, serotonin, GABA, and the NMDA receptors for glutamate. The sedative effects of ethanol are mediated through binding to GABA receptors and glycine receptors (alpha 1 and alpha 2 subunits). It also inhibits NMDA receptor functioning. In its role as an anti-infective, ethanol acts as an osmolyte or dehydrating agent that disrupts the osmotic balance across cell membranes.

    Pharmacodynamics

    Alcohol produces injury to cells by dehydration and precipitation of the cytoplasm or protoplasm. This accounts for its bacteriocidal and antifungal action. When alcohol is injected in close proximity to nerve tissues, it produces neuritis and nerve degeneration (neurolysis). Ninety to 98% of ethanol that enters the body is completely oxidized. Ethanol is also used as a cosolvent to dissolve many insoluble drugs and to serve as a mild sedative in some medicinal formulations. Ethanol also binds to GABA, glycine, NMDA receptors and modulates their effects. Ethanol is also metabolised by the hepatic enzyme alcohol dehydrogenase.

    Metabolism

    Hepatic. Metabolized by cytochrome P450 enzyme CYP2E1.

    Indication

    For therapeutic neurolysis of nerves or ganglia for the relief of intractable chronic pain in such conditions as inoperable cancer and trigeminal neuralgia (tic douloureux), in patients for whom neurosurgical procedures are contraindicated.

    Measured Affinities

    Guide to PHARMACOLOGY

    Measured binding and functional data for ethanol, curated by the IUPHAR/BPS Guide to PHARMACOLOGY. Each row cites the paper it came from. Lower concentrations mean tighter binding — a value in the sub-nanomolar range indicates a very potent interaction.

    Target Action Measure Value Concentration Species Source
    TRPV6 TRPV6 Activation pEC50 0.82 151,356,127 nM Human PMID 35705057
    5-HT3A Htr3a Positive - — — Mouse —
    Glycine Receptor (All subtypes) Potentiation - — — Human PMID 8700149
    Kir3.1 Kcnj3 Agonist - — — Mouse —
    Kir3.2 Agonist - — — None —
    Kir3.4 Kcnj5 Activator - — — Mouse —

    Reading this. pKi, pEC50 and pIC50 are negative log molar values, so a higher number means a tighter interaction; the concentration column converts them for you. Values from non-human species are laboratory measurements and do not translate directly to human effect. Receptor affinity is not a dose — it describes what a molecule binds, not how much of it is safe to take.

    Toxicity

    PsychonautWiki PubChem DrugBank

    The sensible use of alcohol in the short term is extremely unlikely to have any positive or detrimental effects on one's physical health. However, despite the widespread use and alcohol's legality in most countries, many medical sources tend to describe any level of alcohol intoxication as a form of poisoning due to ethanol's damaging effects on the body in large doses. The long-term effects of alcohol consumption range from cardioprotective health benefits for low to moderate alcohol consumption in industrialized societies with higher rates of cardiovascular disease to severe detrimental effects in cases of chronic alcohol abuse. High levels of alcohol consumption are associated with an increased risk of alcoholism, malnutrition, chronic pancreatitis, alcoholic liver disease, and cancer.

    Carcinogenicity

    Group 1: Carcinogenic to humans

    Long-term effects

    The main active ingredient of wine, beer and distilled spirits is alcohol. Drinking small quantities of alcohol (less than one drink in women and two in men per day) is debated to decreased the risk of heart disease, stroke, diabetes mellitus, and early death. Drinking more than this amount, however, increases the risk of heart disease, high blood pressure, atrial fibrillation, and stroke.

    Tolerance & Pharmacokinetics

    drugs.wiki

    No tolerance chart. Our decay curves for these drugs were estimates, and a curve can make tolerance look longer-lasting than it is, which is the dangerous direction.

    How fast tolerance to these drugs fades after a break has not been measured well enough to draw, so don't count on a dose you used to take still being safe: after time off, start with a much smaller amount and don't use alone. Mixing sedatives with each other, with alcohol or with opioids sharply raises the risk of a fatal overdose. If you've been using regularly, don't stop suddenly: withdrawal from benzodiazepines, alcohol or GHB/GBL can cause seizures or delirium, so get medical help to cut down gradually.

    Also reported in combinations. In the 991 Alcohol reports where another drug was taken too, 134 (13.5%) mention hospital, emergency services or an overdose, 39 (3.9%) a seizure and 36 (3.6%) psychosis. In the 145 single-substance reports: 15.2%, 4.1% and 0.0%. These are not in the figures above: they cannot be put down to Alcohol alone, and a mention is not always something that happened to the writer.

    Dosage Distribution

    Dose distribution from experience reports, one dose per report (the first listed). Doses above Q3 + 3×IQR, far above what people typically take, are left out of the median and range and listed under each route: most are real heavy doses or overdoses, not mistakes.

    Median: 375.0 ml IQR: 300.0–750.0 ml n=40

    1 report gave a dose above the typical range (2,250 ml), so it is not in the figures above. Listing a dose here does not mean it is safe.
