Systematic review of topical treatments for fungal infections of the skin and nails of the feet. (1/66)

OBJECTIVE: To identify and synthesise the evidence for efficacy and cost effectiveness of topical treatments for superficial fungal infections of the skin and nails of the feet. DESIGN: Systematic review. INTERVENTIONS: Topical treatments for superficial fungal infections. MAIN OUTCOME MEASURES: Cure confirmed by culture and microscopy for skin and by culture for nails in patients with clinically diagnosed fungal infections. RESULTS: Of 126 trials identified in 121 papers, 72 (57.1%) met the inclusion criteria. Placebo controlled trials yielded pooled relative risks of failure to cure skin infections: allylamines (0.30, 95% confidence interval 0.24 to 0.38); azoles (0.54, 0.42 to 0.68); undecenoic acid (0.28, 0. 11 to 0.74); and tolnaftate (0.46, 0.17 to 1.22). Although meta-analysis of 11 trials comparing allylamines and azoles showed a relative risk of failure to cure of 0.88 (0.78 to 0.99) in favour of allylamines, there was evidence of language bias. Seven reports in English favoured allylamines (0.79, 0.69 to 0.91), but four reports in foreign languages showed no difference between the two drugs (1. 01, 0.90 to 1.13). Neither trial of nail infections showed significant differences between alternative topical treatments. CONCLUSIONS: Allylamines, azoles, and undecenoic acid were efficacious in placebo controlled trials. There are sufficient comparative trials to judge relative efficacy only between allylamines and azoles. Allylamines cure slightly more infections than azoles but are much more expensive than azoles. The most cost effective strategy is first to treat with azoles or undecenoic acid and to use allylamines only if that fails.  (+info)

Opposite effects of GABA(A) and GABA(C) receptor antagonists on the b-wave of ERG recorded from the isolated rat retina. (2/66)

The largest component in the fully dark-adapted ERG is a corneal-positive response, known as the b-wave, and believed to originate from depolarizing (ON-type) bipolar cells. The two types of GABA receptors, GABA(A) and GABA(C) have been reported to exist on bipolar cells in rat retina. The goal of these experiments was to find whether these GABA receptors participate in the generation of the b-wave of electroretinogram (ERG). ERGs were recorded from the isolated rat retinas. The P(2)(t) component, obtained by subtracting the ERGs measured before the application of 50 micrograms APB from those measured after the application of 50 micrograms APB, was used as an indicator of depolarizing bipolar cell activity. Photovoltages, the fast P(3)(t) component of ERG, were registered between the two microelectrodes across the rod outer segments. Bicuculline and 3-aminopropylphosphonic acid (3-APA) were used as selective antagonists of GABA(A) and GABA(C) receptors, respectively. It was found that the GABA(A) and GABA(C) receptors antagonists have opposite effects on the b-wave: bicuculline increased the b-wave amplitude, while 3-APA reduced the amplitude of the b-wave. Neither bicuculline nor 3-APA affect photoreceptors.  (+info)

New therapies on the horizon. (3/66)

Statins have proved to be potent drugs for reducing low-density lipoprotein cholesterol (LDL-C) levels. However, because the response to current statin therapy regimens is not always sufficient to reach defined goal levels, additional drugs to lower LDL-C are needed. New drugs may soon be available to lower LDL-C levels by mechanisms that differ from those of the statins. Among these new agents are a bile acid binding resin, inhibitors of bile acid transport, inhibitors of cholesterol transport, inhibitors of cholesterol esterification, and triglyceride-lowering agents.  (+info)

The development of an in-vitro perfusion system for studies on cultured cells. (4/66)

The design and use of a perfusion system, using a modified flow chamber for studies on cultured animal cells, is described. Rat thoracic aorta smooth muscle cells were isolated by an explant method and grown on Thermanox coverslips. These were introduced into the flow chamber. A flow rate of 25ml/min and a shear stress of 14.6 dynes/cm2 (12 dyne = 10 microN) (both within physiological limits) were maintained. Cells remained attached to the coverslips after 8h of perfusion with culture medium. The effect of exposing rat smooth muscle cells to the cardiovascular toxin, allylamine, is also described. The components of the system are routinely available, simple to clean, easy to assemble and sterilize. The incorporation of an in-line sensor that monitors pH, PO2, PCO2 and temperature ensures that the perfusion conditions remain within physiological limits. Automation means that minimal supervision is required. This system provides a potential mechanism in which cultured vascular cells may be perfused under controlled haemodynamic conditions, and their response to a cytotoxin may be evaluated.  (+info)

Overview of pharmacologic therapy for the treatment of dyslipidemia. (5/66)

Although the National Cholesterol Education Program Adult Treatment Panel III (ATP III) guidelines stress the importance of nonpharmacologic lipid modification interventions such as diet and exercise, the guidelines also recognize that many patients will require drug therapy to achieve low-density lipoprotein cholesterol (LDL-C) target goals. Currently available lipid-modifying drugs include bile acid sequestrants (or resins), fibrates, nicotinic acid, and statins, with each class exerting different effects on the lipid profile. In addition, nonprescription agents such as plant stanols and sterols have been shown to be effective in modifying plasma lipids. Of these agents, the statins are the most effective, most widely prescribed, and best-tolerated form of lipid-lowering drug therapy. New formulations of other drugs, such as niacin and bile acid sequestrants, can also improve treatment regimes and reduce side effects, thereby improving patient compliance with these therapies. In patients who have high levels of LDL-C and triglycerides together with low concentrations of high-density lipoprotein cholesterol (HDL-C), combination therapy may be required. Ezetimibe, a selective cholesterol absorption inhibitor, is the first of a new class of lipid-lowering agents and provides a new agent for the management of patients with dyslipidemia. Data from the ezetimibe clinical development program suggests that this agent can be used alone or in combination with statins to reduce LDL-C, improve compliance, and bring more patients to ATP III target goal.  (+info)

Regulation of alpha7-integrin expression in vascular smooth muscle by injury-induced atherosclerosis. (6/66)

Injury of vascular smooth muscle cells (VSMCs) by allylamine (AAM) leads to phenotypic changes associated with atherogenic progression including increased proliferation, migration, and alterations in cell adhesion. In the present study, the relationship between AAM-induced vascular injury and expression of the alpha(7)-integrin subunit was investigated. The alpha(7)-mRNA and protein expression were examined using real-time RT-PCR, fluorescence-activated cell sorting analysis (FACS), immunohistochemistry, and immunoblotting. In cultured VSMCs from aortas of AAM-treated rats (70 mg/kg for 20 days), alpha(7)-mRNA levels were increased more than twofold compared with control cells. No change was seen in beta(1)-integrin expression. FACS analysis revealed increased cell surface expression of alpha(7)-protein (25 +/- 9%; *P < 0.05). AAM treatment of naive VSMCs enhanced alpha(7)-mRNA expression (2.4 +/- 0.7-fold, mean +/- SE; *P < 0.05). The increased alpha(7)-mRNA expression was attenuated by the amine oxidase inhibitor semicarbazide and the antioxidant pyrrolidine dithiocarbamate, which confirms a role for oxidative stress in modulating alpha(7)-expression. In vivo alpha(7)-mRNA and protein expression were enhanced in the aortas of AAM-treated rats. In addition, increased alpha(7)-integrin expression facilitated AAM VSMC adhesion to laminin more efficiently compared with control (51 +/- 2%; *P < 0.05). Chemical injury induced by AAM significantly enhances alpha(7)-integrin expression in VSMCs. These findings implicate for the first time the expression of alpha(7)-integrin during the response of VSMCs to vascular injury.  (+info)

Ketogenic diet decreases circulating concentrations of neuroactive steroids of female rats. (7/66)

Ketogenic diet (KD) is used to manage intractable epilepsy; however, the mechanisms underlying its therapeutic effects are not known. Steroid hormones, such as progesterone and testosterone, are derived from cholesterol, and are readily 5alpha-reduced to dihydroprogesterone and dihydrotestosterone, which are subsequently converted to 5alpha-pregnan-3alpha-ol-20-one (3alpha,5alpha-THP) and 3alpha-androstanediol, neuroactive steroids that can influence seizures. The present study examined the effects of the KD on circulating concentrations of these neuroactive steroids, and their precursors, in intact female rats. Thirty-six, 22-day-old female Sprague-Dawley rats (weaned at 21 days) were fasted for 8 hours prior to placement on one of three dietary regimens for 6 weeks: ad libitum chow, calorie-restricted chow, or KD. After 6 weeks of the diet, when six rats in each dietary condition were in diestrus and six were in behavioral estrus, all rats were administered pentylenetetrazole (PTZ, 70 mg/kg, i.p.). The latency and incidence of seizures were recorded by an observer who was uninformed of the estrous cycle and dietary treatment conditions of the rats. Immediately after each test, trunk blood was obtained for later measurement of pregnane (progesterone, dihydroprogesterone, 3alpha,5alpha-THP) and androstane (testosterone, dihydrotestosterone, 3alpha-androstanediol) neuroactive steroid concentrations in plasma by radioimmunoassay. KD tended to lengthen the latency to, and significantly reduced the number of, PTZ-induced barrel roll seizures. KD also significantly reduced plasma levels of the pregnane (dihydroprogesterone, 3alpha,5alpha-THP) and androstane (dihydrotestosterone, 3alpha-androstanediol) 5alpha-reduced metabolites. These data suggest that levels of pregnane and androstane neuroactive steroids, or their precursors, may underlie some of the antiseizure effects of KD.  (+info)

Asymmetric synthesis of 4,5,6- and 3,4,5,6-substituted azepanes by a highly diastereoselective and enantioselective lithiation-conjugate addition sequence. (8/66)

Asymmetric syntheses of 4,5,6- and 3,4,5,6-substituted azepanes have been achieved by highly diastereoselective and enantioselective (-)-sparteine-mediated asymmetric lithiation-conjugate additions of N-Boc-N-(p-methoxyphenyl)-2,3-substituted allylamines to a beta-aryl alpha,beta-unsaturated ester followed by hydrolysis, cyclization, and reduction. Access to the enantiomeric adduct is provided by an invertive lithiation-stannylation-lithiation sequence.  (+info)

The bile acid sequestrants are a group of resins used to bind certain components of bile in the gastrointestinal tract. They disrupt the enterohepatic circulation of bile acids by combining with bile constituents and preventing their reabsorption from the gut. In general, they are classified as hypolipidemic agents, although they may be used for purposes other than lowering cholesterol. They are used in the treatment of chronic diarrhea due to bile acid malabsorption. Bile acid sequestrants are polymeric compounds that serve as ion-exchange resins. Bile acid sequestrants exchange anions such as chloride ions for bile acids. By doing so, they bind bile acids and sequester them from the enterohepatic circulation. The liver then produces more bile acids to replace those that have been lost. Because the body uses cholesterol to make bile acids, this reduces the amount of LDL cholesterol circulating in the blood. Bile acid sequestrants are large polymeric structures, and they are not significantly ...
Long-term (52â 78 weeks) treatment with colesevelam HCl added to metformin therapy in type 2 diabetes mellitus patients Harold E BaysLouisville Metabolic and Atherosclerosis Research Center, Louisville, Kentucky, USAObjective: To evaluate the long-term safety, tolerability, and efficacy of colesevelam HCl (colesevelam) in type 2 diabetes mellitus patients receiving metformin monotherapy or metformin combination therapy.Methods: This post-hoc subgroup analysis examined data from type 2 diabetes mellitus patients aged 18 to 75 years with a hemoglobin A1c of 7.5% to 9.5%, who received metformin as part of their treatment via their participation in one of three randomized, double-blind base studies wherein colesevelam (3.75 g/day) or a placebo was added to existing metformin-, insulin-, or sulfonylurea-based treatment.

N2 - We have developed a model of aortic smooth muscle necrosis in adult Sprague Dawley rats by feeding them two vascular toxins (allylamine HCl, or AA, and β-aminopropionitrile, or βAPN) in concert for 10 days. Either toxin given alone does not cause aortic lesions. In order to shed light on the mechanism of the synergistic action of these two toxins we fed known modulators of AA or βAPN toxicity to rats concurrently with the two toxins. As modulators we used (a) semicarbazide (98 mg/kg/day, given 4 h prior to toxins), a known inhibitor of the vascular enzyme SSAO which metabolizes AA (b) L-cysteine (1.5% in rat chow, beginning 3 days prior to toxins), which has been shown to reduce the toxic effects of βAPN; and (c) phenelzine sulphate (3 mg/kg/day, given 4 h prior to toxins), an inhibitor of ...

Bile acids promote bile formation and facilitate dietary lipid absorption. Animal and human studies showing disturbed bile acid metabolism in diabetes mellitus suggest a link between bile acids and glucose control. Bile acids are activating ligands of the farnesoid X receptor (FXR), a nuclear receptor with an established role in bile acid and lipid metabolism. Evidence suggests a role for FXR also in maintenance of glucose homeostasis. Animal and human studies employing bile acid sequestrants (bile acid binding agents), which interrupt the enterohepatic circulation of bile acids and effectively reduce plasma cholesterol, support a link between bile acid and glucose metabolism. In lipid-lowering trials, bile acid sequestrants, such as colesevelam hydrochloride, colestyramine (cholestyramine) and colestilan (colestimide), have also been shown to lower plasma glucose and glycosylated haemoglobin levels, suggesting the utility of these agents as a potential therapy for type 2 diabetes. In this ...

Abstract : Non-viral gene carriers for safe and efficient gene transfection have become of particular interest among researchers of different disciplines ranging from physical chemistry to biotechnology. Recently polymeric vectors have been extensively studied as potentially new gene transfer agents. Until now most of the research efforts were made to optimize the gene-to-polymer weight ratio of polyplexes for safe and efficient gene transfection. In this work, we report on the development of novel poly(allylamine) derivatives with different balance of the primary, secondary, tertiary, and quaternary amino groups. All derivatives were able to complex pDNA into polyplexes at low gene-to-polymer weight ratios i.e., 1:1 or 1:2. Moreover, the examined polyplexes were less cytotoxic and showed better transfection efficiency when compared to linear poly(ethyleneimine). These results indicate that the presence of quaternary ammonium groups is important in the formation of stable polyplexes. Polymers ...

A bulk polymerization method was used to easily and efficiently prepare homo-veratric acid (3,4-dimethoxyphenylacetic acid)-imprinted polymers from eight basic monomers: 2-vinylpyridine, 4-vinylpyridine, 1-vinylimidazole, N-allylaniline, N-allylpiperazine, allylurea, allylthiourea, and allylamine, in the presence of homoveratric acid as a template in N,N-dimethylformamide as a porogen. The imprinted polymer prepared from allylamine had the highest affinity to the template, showing an imprinting factor of 3.43, and allylamine polymers MIP8/NIP8 were selected for further studies. Their binding properties were analyzed using the Scatchard method. The results showed that the imprinted polymers have two classes of heterogeneous binding sites characterized by two pairs of Kd, Bmax values: Kd(1) = 0.060 μmol/mL, Bmax(1) = 0.093 μmol/mg for the higher affinity binding sites, and Kd(2) = 0.455 μmol/mL, Bmax(2) = 0.248 μmol/mg for the lower affinity binding sites. Non-imprinted polymer has only one class of

Terbinafine is an allylamine antifungal medication. The medication can be administered orally or topically as a cream. The topical treatment was officially approved by the FDA in 1993 and can be bought over the counter. The oral treatment was approved in 1996 and widely distributes in the central nervous system, hair and nail beds and may remain there for up to three months because of extended elimination from skin and adipose tissue. Terbinafine is metabolized in the liver and 70% is excreted in the urine.. Mechanism: Terbinafine has a fungicidal effect by inhibiting the enzyme squalene monooxygenase which is involved in the synthesis of sterol in fungi. This inhibits fungal sterol biosynthesis by decreasing ergosterol levels. Fungal membranes are not able to grow because ergosterol is one of the main components of the fungal cell membrane. Additionally, squalene accumulates which weakens the cell membrane. Orally, the drug is very effective due to its ability to concentrate within the ...

Introduction Bile acid sequestrants (BAS) were the first class of lipid-lowering drug to be developed for reducing blood cholesterol levels.1 Now, after their introduction 30 years ago, BAS still continue to command a position in the treatment of hyperlipidaemia.2 How do BAS work? BAS bind to negatively charged b ...
Monday - 13th March 2017 - off to see my GP to get a prescription for Colesevelam, a bile acid sequestrant. He greeted me with "bloody hell, you look well!" I didnt understand the reason for his comment until later. We agreed on the new drug and he also reviewed my existing medications. So far so good.. He had been reading my medical record, the last entry of which was a trip to A&E with jaundice. He had assumed that I was back to see him with a recurrence of the problem, hence his comment. He asked me what the plan was following discharge back at the beginning of February. As far as I was concerned I had undergone a follow-up ultrasound scan and it was now matter closed. Clearly he thought there should have been some follow-up. He was rather miffed that I had heard nothing and said that he would chase it up.. We then had a fairly lengthy discussion on gallstones and surgery to have my gallbladder removed. That was a bit of a shock. I had gone in to get a prescription and come away with a ...
TY - JOUR. T1 - Terbinafine inhibits endothelial cell migration through suppression of the Rho-mediated pathway. AU - Ho, Pei Yin. AU - Zhong, Wen-Bin. AU - Ho, Yan Soon. AU - Lee, Wen Sen. PY - 2006/12. Y1 - 2006/12. N2 - We showed previously that terbinafine, an allylamine with fungicidal activity, could inhibit angiogenesis by suppressing the endothelial cell proliferation. In the present study, we further showed that terbinafine (0-120 μmol/L) dose dependently inhibited the adhesion and migration of human umbilical vascular endothelial cells (HUVEC). Western blot analysis showed that terbinafine decreased the levels of Ras protein and membrane-bound RhoA protein. Moreover, the terbinafine-induced migration inhibition in HUVEC was prevented by pretreatment with farnesol or geranylgeraniol. Pretreatment of HUVEC with Ras inhibitor peptide or a ROCK (a kinase associated with RhoA for transducing RhoA signaling) inhibitor, Y27632, abolished the farnesol- or geranylgeraniol-induced prevention ...
Layer-by-layer structures (e.g. polyelectrolyte multilayers and protein-polyelectrolyte multilayers) play a very important role in surface modification processes. In the present study, electrokinetic measurements were applied for the investigation of poly(allylamine hydrochloride)/poly(sodium 4-styrenesulphonate) (PAH/PSS) multilayer formation, with PAH being a terminal layer, as a function of pH. Additionally, the effect of supporting electrolyte (KCl) concentration on multilayer formation was tested. Silica particles were used as the solid substrate. Furthermore, the adsorption of bovine serum albumin (BSA) on previously formed multilayer was examined as a function of pH and BSA concentration. It was confirmed that the electrokinetic measurements are suitable for monitoring the formation of various multilayers. In all investigated systems the process of multilayer formation was found to depend on conditions (ionic strength and pH) under which the multilayer was formed. Moreover, in the case of ...
The layer-by-layer ionic self-assembly of silica nanoparticles (SiO2 NPs) and poly(allylamine hydrochloride) (PAH) can yield high-quality, tunable, and cost-effective anti-reflection coatings (ARCs). However, these purely ionic films lack the necessary scratch resistance for long-term stability. The addition of the
Stroke causes extensive cellular loss that leads to a disintegration of the afflicted brain tissue. Although transplanted neural stein cells can recover some of the function lost after stroke, recovery is incomplete and restoration of lost tissue is minimal. The challenge therefore is to provide transplanted cells with matrix support in order to optimise their ability to engraft the damaged tissue. We here demonstrate that plasma polymerised allylamine (ppAAm)-treated poly(D,L-lactic acid-co-glycolic acid) (PLGA) scaffold particles can act as a structural support for neural stem cells injected directly through a needle into the lesion cavity using magnetic resonance imaging-derived co-ordinates. Upon implantation, the neuro-scaffolds integrate efficiently within host tissue forming a primitive neural tissue. These neuro-scaffolds could therefore be a more advanced method to enhance brain repair. This study provides a substantial step in the technology development required for the translation of ...
Described and claimed are biologically useful crosslinked copolymers of vinyl pyrrolidone and allylamine suitable for various preventative and therapeutic applications to intact or injured skin. Coatings of these copolymers, either preformed or prepared in situ on the skin may deliver medicaments to the skin, may serve as an iontophoretic medium, may provide electrical contact with the body, may regulate or control moisture loss from injured integument. Monolithic devices for the delivery of pharmaceutically active agents within living tissue may be formulated from these copolymers.
TY - JOUR. T1 - Adult rat myocardial slices. T2 - A tool for studies of comparative cardiotoxicity. AU - Parrish, A. R.. AU - Dorr, Robert T. AU - Gandolfi, A Jay. AU - Brendel, K.. PY - 1994. Y1 - 1994. N2 - The applicability of myocardial slices in comparative cardiotoxicity studies was investigated using the known cardiotoxicants allylamine (AAM) and doxorubicin (DOX). Precision-cut adult rat myocardial slices are a recently developed in vitro system. Previously, it has been demonstrated that myocardial slices are viable for up to 24 hr in organ culture. Myocardial slices exhibited a concentration- and time-dependent loss of viability in response to exposure to AAM or DOX (10-7, 10-6 or 10-5 m) during 24 hr in culture, as assessed by biochemical parameters including protein synthesis, ATP content, lipid peroxidation and the loss of the cytosolic enzyme creatine kinase. Protein synthesis and ATP content were sensitive indicators of slice viability, while lipid peroxidation was affected only by ...
We present a detailed structural and surface-enhanced Raman scattering (SERS) study of poly(allylamine) modified with Os (byp)2 ClPyCHO (PAH-Os) and gold nanoparticles self-assembled multilayers [PAH-Os+ (Au-nanoparticlesPAH-Os)n, n=1 and 5]. Atomic force microscopy and variable-angle spectroscopic ellipsometry measurements indicate that the first nanoparticle layer grows homogenously by partially covering the substrate without clustering. Analyzing the sample thickness and roughness we infer that the growth process advances thereafter by filling with nanoparticles the interstitial spaces between the previously adsorbed nanoparticles. After five immersion steps the multilayers reach a more compact structure. The interaction between plasmons of near-gold nanoparticles provides a new optical absorption around 650 nm which, in addition, allows a more effective SERS process in that spectral region than at the single-plasmon resonance (∼530 nm). We compare the electronic resonance Raman and SERS ...

RESULTS Fasting plasma glucose and HbA1c decreased with colesevelam (from 5.9 ± 0.1 to 5.7 ± 0.1 mmol/L, P , 0.05, and from 5.86 ± 0.06 to 5.76 ± 0.06%, P = 0.01, respectively), but fasting insulin did not change. Colesevelam had no effect on any FSIGT measures. In contrast, the MTT incremental area under the curve (iAUC) for both glucose (from 249.3 ± 28.5 to 198.8 ± 23.6 mmol/L ⋅ min, P , 0.01) and insulin (from 20,130 [13,542-35,292] to 13,086 [9,804-21,138] pmol/L ⋅ min, P , 0.05) decreased with colesevelam. However, the ratio of iAUC insulin to iAUC glucose was not changed. iAUC for cholecystokinin (CCK) increased (from 43.2 [0-130.1] to 127.1 [47.2-295.2] pmol/L ⋅ min, P , 0.01), while iAUC for fibroblast growth factor 19 decreased (from 11,185 [1,346-17,661] to 2,093 [673-6,707] pg/mL ⋅ min, P , 0.01) with colesevelam. However, iAUC for glucagon, glucose-dependent insulinotropic peptide, and glucagon-like peptide 1 did not change. ...
In a final effort to get the yellow out of my water, I tried a third brand of sequestrant/chelating agent, Sequa-Sol It worked. The water is the best looking it has been to date. The previous two were Metal Free and Sea Klear Metal Klear. The MSDS on this new one says the active ingredient is Sodium Citrate. It is listed as a chelating agent where the previous two used Acrylamide-Acrylic Acid Copolymer, listed as a sequestrant. I cant find much that explains the difference, at least as
Lodalis Tablet is used for high cholesterol levels, high cholesterol and other conditions. Lodalis Tablet contains the following active ingredients: Colesevelam Hydrochloride.
Cholesterol-lowering drugs are known as "antihyperlipidemic agents". There are five major groups: (1) Fibric acid derivatives - Atromid-S (clofibrate) and Lopid (gemdibrozil), which work by preventing the liver from making or releasing cholesterol into the bloodstream, (2) Bile acid sequestrants - Questran (cholestryamine) and Colestid (cholestipol), which bind to bile acids and prevent their absorption, (3) Nicotinic acid - Nicolar (nicotinic acid), which decreases the secretion of VLDL thus the formation of "bad" LDL cholesterol, (4) Probucol - Lorelco (probucol), which enhances the clearance of cholesterol including LDL and HDL cholesterol, and (5) HMG-CoA reductase inhibitors - Mevacor (lovastatin), Pravastatin, and Zocor (simvastatin), which work to help lower LDL cholesterol ...
Drugs to reduce cholesterol and other lipids in blood. Classes of drugs used for this purpose include statins, bile acid sequestrants, nicotinic acid, and fibrates.
The strategy underlying the addition of a second or third agent is to optimize improvements in the lipid profile achieved by initial (usually statin) therapy. This strategy is based on the empirical assumption that further improvement in the lipid profile beyond that initially achieved will yield additional CVD benefit. However, there are as yet no controlled clinical trials comparing statin monotherapy with combination treatment.. It has been clearly shown that the addition of ezetimibe to a statin will lower LDL cholesterol to goal more often than statin monotherapy will.28 Bile acid sequestrants may also help to lower LDL cholesterol but should be used with caution because they have a triglyceride-raising effect in hypertriglyceridemic patients.29. It is also clear that achievement of all three lipid goals is more likely with statin plus fibrate or statin plus niacin combinations.30-32 However, the added complexity and risks of combination therapy in the absence of persuasive clinical trial ...

Bile acid sequestrants and nicotinic acid have cholesterollowering properties. They may occasionally be useful alone or in combination with statin therapy. However, their side-effects limit wider application.. 8.8 Treatment directed at other components of the lipid profile. Whereas low levels of HDL-C and high levels of TG are undoubtedly associated with a higher cardiovascular disease risk, no currently available treatment directed at reversing these changes has been shown to significantly benefit cardiovascular outcome.. A high triglyceride level, particularly if ,10 mmol/l, can result in acute pancreatitis and should be treated without delay.. 9. Special circumstances. 9.1 Metabolic syndrome.
