Toxicity Profile
| Route of Exposure | Oral, rapidly absorbed. Blood alcohol level and the time necessary to achieve it are controlled largely by the rapidity and extent of ethanol consumption. |
|---|---|
| Mechanism of Toxicity | Alcohol binds to the GABA receptors (delta subunit), NMDA receptors, Glycine receptors, Serotonin receptors, Acetylcholine receptors, L-channel calcium channels and GIRK channels. Ethanol acts in the central nervous system primarily by binding to the GABAA receptor, increasing the effects of the inhibitory neurotransmitter GABA. Ethanol within the human body is converted into acetaldehyde by alcohol dehydrogenase. Acetaldehyde is linked to most of the clinical effects of alcohol. It has been shown to increase the risk of developing cirrhosis of the liver and multiple forms of cancer. During the metabolism of alcohol via the respective dehydrogenases, NAD (Nicotinamide adenine dinucleotide) is converted into reduced NAD. Normally, NAD is used to metabolise fats in the liver, and as such alcohol competes with these fats for the use of NAD. Prolonged exposure to alcohol means that fats accumulate in the liver, leading to the term 'fatty liver'. Continued consumption (such as in alcoholism) then leads to cell death in the hepatocytes as the fat stores reduce the function of the cell to the point of death. These cells are then replaced with scar tissue, leading to the condition called cirrhosis. |
| Metabolism | Ethanol is metabolized to acetaldehyde by three enzymes: 1. Alcohol dehydrogenase metabolized methanol to acetaldehyde, which is oxidized by acetaldehyde dehydrogenase to acetate. 2. Catalase metabolizes ethanol by utilizing H2O2 supplied by the actionhs of NADPH oxidase and xanthine oxidase. This normally accounts for more than 10% of ethanol metabolism. 3. CYP2E1, is the principal component of the hepatic microsomal ethanol oxidizing system, MEOS) |
| Toxicity Values | LD50: 5628 mg/kg (Oral, rat) |
| Lethal Dose | The fatal dose of ethanol is 300-400 mL of pure ethanol (600-800 mL of 50% spirits), for the average adult if consumed in less than one hour. More specifically, the lethal dose of alcohol is 5-8g/kg (3g/kg for children). |
| Carcinogenicity (IARC Classification) | Ethanol in alcoholic beverages is carcinogenic to humans (Group 1). |
| Minimum Risk Level | |
| Health Effects | Acute: At 0.1% blood alcohol levels individuals experience CNS depression, nausea, possible vomiting, impaired cognition and impaired motor and sensory function. Accidents or injury can also occur due to the side effects of loss of coordination, slowed reaction time, sleepiness and impaired judgment. At >0.14% blood alcohol levels there is decreased blood flow to the brain. At greater than 0.3% blood alcohol there is a marked degree of stupefaction and possible unconsciousness. At levels greater than 0.4% there is a risk of death. Acute consumption leading to blood alcohol levels greater than 0.5% is almost universally fatal. Chronic: high levels of alcohol consumption are associated with an increased risk of alcoholism, malnutrition, chronic pancreatitis, alcoholic (fatty) liver disease, and cancer. Frequent drinking of alcoholic beverages has been shown to be a major contributing factor in cases of elevated blood levels of triglycerides. In addition, damage to the central nervous system and peripheral nervous system can occur from chronic alcohol abuse. The long-term use of alcohol is capable of damaging nearly every organ and system in the body. The developing adolescent brain is particularly vulnerable to the toxic effects of alcohol. In addition, the developing fetal brain is also vulnerable, and fetal alcohol syndrome (FAS) may result if pregnant mothers consume alcohol. The net effect of alcohol consumption on global human health is quite detrimental, with an estimated 3.8% of all global deaths and 4.6% of global disability-adjusted life-years attributable to alcohol. Ethanol is considered a teratogen (causing fetal alcohol syndrome) and a Group 1 carcinogen because of the carcinogenicity of acetaldehyde (a major metabolite of alcohol). |
| Treatment | If you suspect someone has alcohol poisoning, call for an ambulance to take them to a hospital. While you're waiting: try to keep them sitting up and awake, give them water if they can drink it. If they've passed out, lie them on their side in the recovery position and check they're breathing properly, keep them warm and stay with them and monitor their symptoms. Acute alcohol poisoning is a medical emergency due to the risk of death from respiratory depression and/or inhalation of vomit if emesis occurs while the patient is unconscious and unresponsive. Emergency treatment for acute alcohol poisoning strives to stabilize the patient and maintain a patent airway and respiration, while waiting for the alcohol to metabolize. Emergency treatment in a hospital can involve: 1) treating hypoglycaemia (low blood sugar) with 50 ml of 50% dextrose solution and saline flush, as ethanol induced hypoglycaemia is unresponsive to glucagon; 2) Administration of the vitamin thiamine to prevent Wernicke-Korsakoff syndrome, which can cause a seizure; 3) application of haemodialysis if the blood concentration is dangerously high (>400 mg%), and especially if there is metabolic acidosis and 4) Providing oxygen therapy as needed via nasal cannula or non-rebreather mask. |

- General Function:
- Voltage-gated calcium channel activity
- Specific Function:
- Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death. The isoform alpha-1C gives rise to L-type calcium currents. Long-lasting (L-type) calcium channels belong to the 'high-voltage activated' (HVA) group. They are blocked by dihydropyridines (DHP), phenylalkylamines, benzothiazepines, and by omega-agatoxin-IIIA (omega-Aga-IIIA). They are however insensitive to omega-conotoxin-GVIA (omega-CTx-GVIA) and omega-agatoxin-IVA (omega-Aga-IVA). Calcium channels containing the alpha-1C subunit play an important role in excitation-contraction coupling in the heart. The various isoforms display marked differences in the sensitivity to DHP compounds. Binding of calmodulin or CABP1 at the same regulatory sites results in an opposit effects on the channel function.

- General Function:
- G-protein activated inward rectifier potassium channel activity
- Specific Function:
- This potassium channel is controlled by G proteins. Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. This receptor plays a crucial role in regulating the heartbeat.

- General Function:
- Receptor binding
- Specific Function:
- Ionotropic receptor with a probable role in the modulation of auditory stimuli. Agonist binding may induce an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane. The channel is permeable to a range of divalent cations including calcium, the influx of which may activate a potassium current which hyperpolarizes the cell membrane. In the ear, this may lead to a reduction in basilar membrane motion, altering the activity of auditory nerve fibers and reducing the range of dynamic hearing. This may protect against acoustic trauma.

- General Function:
- Pdz domain binding
- Specific Function:
- Ionotropic glutamate receptor. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. Binding of the excitatory neurotransmitter L-glutamate induces a conformation change, leading to the opening of the cation channel, and thereby converts the chemical signal to an electrical impulse. The receptor then desensitizes rapidly and enters a transient inactive state, characterized by the presence of bound agonist. In the presence of CACNG4 or CACNG7 or CACNG8, shows resensitization which is characterized by a delayed accumulation of current flux upon continued application of glutamate.
