Purpose:
To review knowledge on therapeutic uses of ethanol and the latter's effectiveness and safety profiles in a range of indications.
Methods:
MEDLINE and PubMed databases were searched for relevant peer-reviewed papers published in English between 1888 and 2018 using the following search terms: ethanol, therapeutic, alcohol withdrawal syndrome, antiseptic, antidote, methanol, ethylene glycol, neurolysis, embolization, cyst, sclerosing agent, sclerotherapy, arteriovenous malformations, ablating agent. Studies providing information about association between alcohol and therapeutic indications, or mechanic explanation for the association were included for review.
Results:
According to the World Health Organization, approximately three millions deaths worldwide are attributable to alcohol consumption each year. However, the low-to-moderate consumption of ethanol has a number of beneficial effects (mainly on cardiovascular mortality and diabetes). Hence, ethanol has an unusual spectrum of effects that seems interesting for therapeutic purposes. Ethanol's risk-benefit ratio appears to be positive in some therapeutic indications such as antidote to methanol or ethylene glycol poisoning, neurolysis, alcohol withdrawal syndrome, or antiseptic.
Conclusion:
With the development of interventional radio technologies, and thus extremely precise access to anatomical structures, alcohol has been given new indications - particularly as an embolization, sclerosing or ablation agent. Moreover, constant progress in our knowledge of ethanol's pharmacodynamics might highlight other therapeutic indications for this compound in the future. Ethanol's low cost and wide availability make it a valuable therapeutic agent, compared with other reference treatments. Furthermore, ethanol has a long track record of safety and effectiveness in the indications mentioned above.

Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...
02:17Physical Properties of Ethers
An ether molecule has a net dipole moment due to the polarity of C–O bonds. Subsequently, boiling points of ethers are lower than those of alcohols of comparable molecular weight and slightly higher than those of hydrocarbons of comparable molecular weight (Table 1).
Ethers can act as hydrogen bond acceptors, making them more water-soluble than hydrocarbons, but since ethers cannot act as hydrogen bond donors, they are much less soluble in water than alcohols. Ethers are considered...
01:20Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
