Table 28­11 lists recommended drugs of choice for each lipoprotein phenotype and alternate agents virus vs cold order cheap bactrim online. Total daily fat intake should be no more than 10­25 g/d virus buster serge purchase 480mg bactrim overnight delivery, or approximately 15% of total calories antibiotic resistant bacteria evolution purchase 480 mg bactrim otc. Secondary causes of hypertriglyceridemia (see Table 28­5) should be excluded or, if present, the underlying disorder should be treated appropriately. Type V hyperlipoproteinemia also requires a stringent restriction of the fat component of dietary intake. In addition, drug therapy is indicated, as outlined in Table 28­11, if the response to diet alone is inadequate. Medium-chain triglycerides, which are absorbed without chylomicron formation, may be used as a dietary supplement for caloric intake if needed for types I and V. Omega-3 fatty acids may be useful in lipoprotein lipase deficiency in some patients. Currently available products include lovastatin, pravastatin, simvastatin, fluvastatin, atorvastatin, and pitvastatin. Combination therapy with a statin plus eztimibe is also rational, since eztimibe inhibits cholesterol absorption across the gut border and adds 12­20% further reduction when combined to a statin or other drugs. Pharmacokinetic parameters in this table are based on studies and reviews presented in the literature. However, in the age groups studied, these abnormalities are common and tend to wax and wane with time irrespective of drug therapy, and no statistical association is known to exist. This decreases the bile acid pool size and stimulates hepatic synthesis of bile acids from cholesterol. Gastrointestinal complaints of constipation, bloating, epigastric fullness, nausea, and flatulence are most commonly reported. The other major limiting complaint is the gritty texture and bulk; these problems may be minimized by mixing the powder with orange drink or juice. Tablet forms of bile acid sequestrants should help in improving compliance with this form of therapy, whereas resin does not improve compliance. Hyperchloremic metabolic acidosis, hypernatremia, and gastrointestinal obstruction have been reported almost exclusively in children, and malabsorption of fat-soluble vitamins is probably most common with high doses. Drug interactions may be avoided by alternating administration times with an interval of six hours or greater between the bile acid resin and other drugs. Colestipol and cholestyramine have comparable side effects; however, colestipol may have better palatability because it is odorless and tasteless. Niacin (nicotinic acid) may also be used in primary hypercholesterolemia in combination with bile acid sequestrants or as monotherapy for this disorder and others (Table 28­11). The principal use of niacin is for mixed hyperlipemia or as a second-line agent in combination therapy for hypercholesterolemia. It is also considered to be the first-line agent or an alternative for the treatment of hypertriglyceridemia and diabetic dyslipidemia. One meta-analysis showed that combination therapy was no more effective than high dose statin therapy. Niacin has many adverse drug reactions that occur commonly; fortunately, most of the symptoms and biochemical abnormalities seen do not require discontinuation of therapy. Cutaneous flushing and itching appear to be prostaglandin-mediated and can be reduced by aspirin 325 mg given shortly before niacin ingestion. Acanthosis nigricans, a darkening of the skin in skinfold areas and an external marker of insulin resistance, may be seen with high doses of niacin. Sustainedrelease products may minimize these complaints in some patients, but controlled trials with regular-release products do not demonstrate much of a difference between sustained- and regular-release products. The only legend form of niacin, Niaspan (Abbott), is an extended release form of niacin with pharmacokinetics intermediate between instant and sustained-release products which are sold as food supplements rather than legend products. In controlled trials, Niaspan is reported to have fewer dermatologic reactions and has a low risk for hepatoxicity. Recent experience with niacin in diabetes suggests that some diabetic patients do not have worsened glycemic control with dose-titration and sustained-release products.

Liver enzyme assays can help to antibiotics for uti pediatric generic 480 mg bactrim determine if a particular type of liver damage is present infection while pregnant buy bactrim 480 mg on line. Therefore it is important to antibiotics for acne does it work buy discount bactrim 480mg on-line know the patterns of drug-related pathology in order to assess adverse reactions when they occur. In many of the patterns of damage that this chapter will review, the first step is a net increase in reactivity that results from the normal processes of metabolism in the liver. This now bioactivated compound if left unconjugated or otherwise unbound is free to react in uncontrolled ways within the cell. Hepatocellular injury can lead to fulminant hepatitis with a corresponding 20% survival rate with supportive care. Centrolobular necrosis, steatohepatitis (steatonecrosis), phospholipidosis, and generalized hepatocellular necrosis are each identifiable by particular biopsy results and subtle differences in clinical presentation. The number of drugs associated with adverse reactions involving the liver is extensive. All other drugs together account for less than 10% of patients hospitalized for elevated liver enzymes. Also called direct or metabolite-related hepatotoxicity, centrolobular necrosis is usually the result of the production of a toxic metabolite. Metabolized by either cytochrome P450 superfamily or by one or more other enzyme families. The xenobiotic receptor is in turn upregulated by other drugs, changes in cholesterol catabolism, and bile acids. The immediate result of the action of these phase I enzymes is the production of a reactive metabolite. These proteins are subject to genetic polymorphism as well, again leading to some patients having an increased risk for toxicity. Mild drug reactions, involving only small amounts of parenchymal liver tissue, may be detected as asymptomatic elevations in the serum aminotransferases. If the reaction is diagnosed at this stage, most of these patients will recover with minimal cirrhosis and thus minimal chronic liver impairment. More severe forms of centrolobular necrosis are accompanied by nausea, vomiting, upper abdominal pain, and jaundice. The protein glutathione provides a ready source of available sulfhydryl groups within the hepatocyte. In addition, the depletion of glutathione changes the mitochondrial oxidized to reduced glutathione ratio resulting in catastrophic shifts in mitochondrial function, accelerating cell necrocytolysis. Early in the process of Reye syndrome, mitochondrial dysfunction leads to the depletion of acyl-coenzyme A and carnitine. Fatty acids accumulate and gluconeogenesis is impaired, resulting in hypoglycemia. A concurrent disruption of the urea cycle occurs, leading to a decrease in the removal of ammonia and a slowing of protein use. A threefold rise in the blood ammonia level and an increase in the prothrombin time are common findings. If not, then ever increasing rates of necrocytolysis will induce an innate immune response and result in hepatitis. The development of this reaction is related to the high concentrations achieved when tetracycline is given intravenously and in doses greater than 1. The mortality of tetracycline steatohepatitis is high (70%­80%), and those who do survive often develop cirrhosis. Sodium valproate also can produce steatonecrosis through the process of bioactivation. Cytochrome P450 converts valproate to delta-4-valproic acid, a potent inducer of microvesicular fat accumulation. Patients with more severe steatonecrosis will present with all the symptoms characteristic of alcoholic hepatitis such as nausea, vomiting, steatorrhea, abdominal pain, pruritus, and fatigue. Patients treated with amiodarone who develop overt hepatic disease tend to have received higher doses of the drug. These patients also have higher amiodarone-to-N-desethyl-amiodarone ratios, indicating a greater accumulation of the parent compound. Amiodarone and its major metabolite N-desethyl-amiodarone remain in the liver of all patients for several months after therapy is stopped.
