Approximately half of people of Asian descent are considered to be sensitive to alcohol due to this condition. [3] Flushing, after consuming one or two alcoholic beverages, includes a range of symptoms: nausea, headaches, light-headedness, an increased pulse, occasional extreme drowsiness, and occasional skin swelling and itchiness. These unpleasant side effects often prevent further drinking that may lead to further inebriation, but the symptoms can lead to mistaken assumption that the people affected are more easily inebriated than others. One possible theory that may explain the effects of famotidine (and similar classed drugs) on the skin erythema or redness secondary to alcohol consumption is because the drugs are H2-antagonists or H2 antihistamines, which are used to treat peptic/gastric ulcers. In essence, if the "Asian flush" is an allergic reaction to the alcohol, then the mechanism of action of H2-antagonists can explain its effects on curtailing or decreasing the redness. However, H2-antagonists do not actually reduce blood concentrations of histamine, but rather works by reversing the effect of histamine on the H2 receptor, and so this theory is disputed. Another theory, is that acetaldehyde causes the redness and vasodialation, and because the H2-antagonist class of medicine inhibits the ADH enzyme(the conversion from ethanol to acetaldehyde) both in the GI tract and in the liver[5], the conversion happens at a much slower pace, reducing the effects acetaldehyde has on the drinker. The idea that acetaldehyde is the cause of the flush is also shown by the clinical use of Antabuse, which blocks the removal of acetaldehyde from the body via ALDH inhibition. The high acetaldehyde concentrations described share similarity to symptoms of the flush(flushing of the skin, accelerated heart rate, shortness of breath, throbbing headache, mental confusion). Although many people with this condition view it as a lifetime inconvenience, some people have suggested that they can condition their body to be more tolerant of alcohol with repeated, moderate drinking, perhaps increasing the concentration of ALDH2 to metabolize acetaldehyde. Unfortunately, acetaldehyde is a known carcinogen; recent research suggests that alcohol flush-afflicted individuals consuming alcohol continually may be at a higher risk for alcohol-related diseases, such as liver and esophageal cancers and digestive tract cancer.[3] Studies in rats have also shown that consumption of carbohydrates significantly increase the metabolism of ethanol through a yet unknown pathway, and without affecting alcohol dehydrogenase activity Individuals who experience the alcohol flushing reaction may be less prone to alcoholism. Antabuse, a drug sometimes given as treatment alcoholism, works by inhibiting acetaldehyde dehydrogenase, causing a five to tenfold increase in the concentration of acetaldehyde in the body. The resulting irritating flushing reaction is intended to discourage alcoholics from drinking
