But the truth will out eventually. . Three years later, i first saw niacin work on somebody else. He was a bona-fide, properly-diagnosed, utterly-incurable, state-hospitalized schizophrenic patient. . I did not see niacin work in the hospital, of course; the only vitamins given there are what you can filter out of your Jell-o and your Tang. . no, the patient was a fellow whose parents were desperate enough try anything, even nutrition. . Perhaps this was because their son was so unmanageably violent that he was kicked out of the asylum and sent to live with them. . On a good day, his Mom and Dad somehow got him to take 3,000 milligrams of niacin and 10,000 mg of vitamin. . Formally a hyperactive insomniac, he responded by sleeping for 18 hours the first night and becoming surprisingly normal within days. .

those clinical studies in the first place. . I personally should have first became aware of a food-brain connection during those all-night, cookie-fired mah-jongg marathons i all-too-regularly indulged in while attending AustralianNationalUniversity. . Though arguably somewhat less than psychotic, my mind was nevertheless pretty whacked out on sugar, junk food and adrenalin by. My mood was destroyed; my mind agitated; unable to sleep, sit still, or smile. Of course, i never entertained even the thought of a nutrition connection. For weve all been carefully taught that drugs cure illness, not diet. And certainly not vitamin supplements!

Whats more, he had proven, with the very first double-blind, placebo-controlled studies in the history of psychiatry, that vitamin B-3 could cure zinkmangel schizophrenia. . you would think that psychiatrists everywhere would have beaten down a path to saskatchewan to replicate the findings of this young Director of Psychiatric Research and his colleague, humphrey osmond,. In modern psychiatry, niacin and schizophrenia are both terms that have been closeted away out of sight. And patients, tranquilized into submission or Prozac-ed into la-laland, are often idly at home or wandering the streets, where either way it is highly doubtful that they will get much in the way of a daily vitamin intake. . Those in institutions fare little better nutritionally. . For everyone knows that vitamins do not cure real diseases. But Dr Hoffer dissents. . For half a century Dr Hoffer has dissented. . His central point has been this: Illness, including mental illness, is not caused by drug deficiency. . But much illness, especially mental illness, may be seen to be caused by a vitamin deficiency. .

Complete resolution of the clinical symptoms is expected within days of stopping niacin, whereas serum enzyme elevations may require several weeks or months to resolve. . Rechallenge with the same form leads to rapid recurrence and should be avoided. . If the injury occurred after switching to a sr formulation, the crystalline form of niacin may be restarted at a lower dose and with caution. Drug Class: Antilipemic Agents ; Vitamins. Top of page, case report, niacin, case. . Hepatocellular hepatitis with jaundice associated with high doses of niacin. Modified from:  Patterson dj, dew ew, gyorkey f, graham. South Med J 1983; 76: 239-241. A 41 year old man with a history of taking.5 grams of niacin daily for 6 months presented with nausea, anorexia, weakness and abdominal pain followed by jaundice. .

When the injury is the result of switching from the crystalline to the sustained release form, the injury may present acutely within days or a few weeks with a prodromal period of nausea, vomiting and abdominal pain, that is followed by jaundice and pruritus. . Early during the injury serum aminotransferase levels are very high and then usually fall rapidly with discontinuation or dose lowering. . The clinical phenotype resembles acute hepatic necrosis, suggesting a direct toxic effect. . Imaging studies of the liver may reveal areas of hypodensity starry sky liver interpreted as focal fatty infiltration that resolves after stopping the drug. . liver biopsy typically shows varying degrees of centrolobular necrosis with only mild inflammation.

Mechanism of Injury, the mechanism of hepatotoxicity is assumed to be an intrinsic toxic reaction related to high serum levels of niacin that overwhelm the high affinity, low concentration nicotinic acid receptors (that are responsible for the flushing response). . The finding that niacin can be restarted at lower doses after an episode of clinically apparent injury indicates that the hepatic damage is unlikely korte to be idiosyncratic or due to hypersensitivity. Outcome and Management, niacin hepatotoxicity appears to be dose dependent and more common with the sustained release form of the drug. . Hepatotoxicity is less common with regular, crystalline niacin or extended release niacin. . Most cases are mild and resolve rapidly upon stopping the medication, although in some instances, the injury is acute and severe and progresses to liver failure that is fatal or requires emergency liver transplantation. .

The elevations are rarely greater than 3 times the upper limit of the normal range and usually resolve spontaneously even with continuation of the drug. . The effect is partially dose related and is more common with doses above 3 g/day. . In some patients, there is an overall decrease in serum proteins synthesized by the liver and, in some instances, coagulopathy with an increase in prothrombin time and decline in serum albumin, coagulation factors and apolipoproteins. . These changes resolve rapidly upon stopping therapy and may not recur with lower doses. Niacin can also cause serious hepatotoxicity, but this is uncommon. . Significant hepatotoxicity is particularly common with high doses of sustained release niacin. . In many cases, the injury becomes apparent after a dose increase or after switching from the regular crystalline to a sustained release form. . The pattern is primarily hepatocellular, although cases with a cholestatic pattern have been described. . The patients present with jaundice, itching, nausea, vomiting and fatigue. .

sr niacin can be taken once daily and is less likely to cause flushing, but is not approved for use in hyperlipidemia and has been associated with a high rates of hepatotoxicity in some studies. . Extended release (ER) capsules and tablets of niacin are available in concentrations ranging from 125 to 1,000 mg, which are approved for use in hyperlipidemia and have not been associated with a higher rate of hepatotoxicity compared to regular niacin. . niacin er is available by prescription and over-the-counter in generic forms and under several brand names such as niaspan and niobid. . The recommended daily dosage of niacin er ranges from 500 to 2,000 mg generally given once daily at bedtime. . niacin is also available in combination with other lipid lowering drugs such as lovastatin (Advicor). . Common side effects of niacin include nausea, fatigue, pruritus and flushing; flushing being a major dose-limiting side effect. Hepatotoxicity, niacin in doses above 500 mg daily causes transient, asymptomatic elevations in serum aminotransferase levels in up to 20 of people. .

The mechanism of action of niacin in hyperlipidemia is not well understood, but is believed to be related to inhibition of camp signaling pathways in adipocytes, which results in decreased release of lipids from fat cells. . niacin was officially approved for use in the United States in 1957 and is still widely used, although its role in management of hyperlipidemia in patients taking statins and other cholesterol lowering agents remains uncertain and controversial. . Regular niacin is available in multiple generic forms, under several brand names (including niacor in many concentrations as either tablets or capsules from 50 to 1,000 mg each. . When used to treat hyperlipidemia, regular niacin is generally referred to as intermediate release ir niacin. . ir-niacin must be taken several times daily and is associated with a high rate of cutaneous flushing. . The recommended dosage for hyperlipidemia is 1 to 6 grams daily, starting at low blijft doses (100 mg three times daily) and increasing at weekly intervals based upon tolerance and effect. .
