Tazarotene is a prodrug and a member of the acetylenic class of retinoids. Following topical application, tazarotene undergoes esterase hydrolysis to form its active metabolite, tazarotenic acid. When treating acne tazarotene may be taken in conjunction with an oral antibiotic. Tazarotene has been shown in peer-reviewed double blinded studies to reduce: mottling and hyperpigmentation, sallowness, fine wrinkling and coarse wrinkling in sun damaged skin. Histological studies have shown that long term (greater than 1 year) use of Tazarotene is associated with a significant reduction in atypical melanocytes and keratocytes - cells considered to be precursors of skin cancer. Some studies have shown long term use of Tazarotene to be associated with increased collagen production and better organization of skin collagen bundles ...

Measurement of cerebral blood flow by the nitrous oxide method before and during intravenous administration of nicotinic acid indicates that cerebral vessels do not respond to this drug. Evidence that contamination of cerebral by extracerebral blood occurs in about 20 per cent of subjects is adduced from the effects of nicotinic acid on the measured cerebral blood flows; studies making use of the intravascular catheter technic to sample internal jugular blood tend to confirm this hypothesis.. ...

The effects of long term treatment with nicotinic acid on lipids, lipoproteins, and the plasma distribution of very low density lipoproteins (VLDL) apoprotein C (ApoC) subspecies were studied in 33 patients with types IIa (n = 9), IIb (n = 11), and IV (n = 13) hyperlipidemias. After 6 months of trea …

Tazarotene (marketed as Tazorac, Avage, Zorac, and Fabior) is a third-generation prescription topical retinoid sold as a cream, gel, or foam. Tazarotene is a member of the acetylenic class of retinoids. This medication is approved for treatment of psoriasis, acne, and sun damaged skin (photodamage). It is commonly sold in two concentrations: 0.05% and 0.1%. Tazarotene is a retinoid prodrug which is converted to its active form, the cognate carboxylic acid of tazarotene, by rapid deesterification in animals and humans. Tazarotenic acid binds to all three members of the retinoic acid receptor (RAR) family: RARα, RARβ, and RARγ but shows relative selectivity for RARβ, and RARγ and may modify gene expression. The clinical significance of these findings is unknown. Common side effects include worsening of acne, increased sensitivity to sunlight, dry skin, itchiness, redness and in some cases extreme drying and cracking of skin. For most patients these side effects are uncomfortable but mild and ...

Obese children and adults display lower spontaneous and stimulated growth hormone (GH) secretion. It is presumed that dysregulation of some of the factors normally involved in controlling GH secretion underlies the hyposomatotropinemia of obesity, given that GH production usually normalizes after weight loss. Free fatty acids (FFA) are one factor thought to be involved in regulation of GH secretion. Niacin is a nicotinic acid derivative that inhibits lipolysis and lowers circulating FFA concentrations. Nicotinic acid derivatives have been used in several adult studies examining GH secretion. Specifically in obese adults, inhibition of lipolysis has been found to increase spontaneous and stimulated GH production, presumably due to direct effects of FFA on hypothalamic GH-regulating neurons. Thus far no pediatric studies have examined the effects of niacin on GH secretion, and there is only one small pediatric study of normal weight prepubertal children growing at the 5th-10th percentile in height ...

Objectives: Nicotinic acid (NA) treatment is associated with benefits in atherosclerosis that are attributed to effects on plasma lipoproteins. The nicotinic acid receptor GPR109A is expressed in monocytes and macrophages, suggesting a possible role for NA in modulating function of these immune cells. This study sought to test the effects of nicotinic acid on human monocytes and explore its mechanisms of action on a range functions that are relevant to atherogenesis.. Methods and Results: Human monocytes were isolated from blood taken from healthy volunteers according to local ethics protocols and informed consent was obtained. NA reduced secretion of pro-inflammatory mediators in human monocytes. In the cells treated with NA, release of TNF-α was attenuated by 49.2 ± 4.5%; IL-6 by 56.2 ± 2.8% and MCP-1 by 43.2 ± 3.1% (n=7, P , 0.01). Quantitative RT-PCR showed that mRNA for each of these inflammatory mediators was similarly reduced. In contrast, mRNA for PPAR-γ was increased by 80.5 ± ...

Nicotinic acid is a unique cholesterol modifying agent that exerts favorable effects on all cholesterol parameters. It holds promise as one of the main pharmacological agents to treat mixed dyslipidemia in metabolic syndrome and diabetic patients. The use of nicotinic acid has always been haunted with concerns that it might worsen insulin resistance and complicate diabetes management. We will discuss the interaction between phosphorous metabolism and carbohydrate metabolism and the possibility that worsening of insulin resistance could be related to adrug induced alteration in phosphorous metabolism, and the implications of that in medical management of diabetes and metabolic syndrome patients with mixed dyslipidemia.

Reduction in total cholesterol (TC) and LDL-cholesterol (LDL-C) forms one of the principal objectives of most cardiovascular secondary prevention strategies. Many patients being treated with statins, however, have significant residual dyslipidaemia, with many having suboptimal HDL-cholesterol (HDL-C) levels. The addition of nicotinic acid to a statin has been shown to improve this profile, although clinical outcome evidence is currently lacking. This study set out to model the impact of nicotinic acid therapy on cardiovascular risk in these patients, based on Framingham risk assessments on a cohort of patients drawn from UK general practitioner records.. ...

An attractive option for those with dyslipidemia, nicotinic acid has been utilized therapeutically for more than 50 years. Dyslipidemia is characterized as an elevation of blood levels of cholesterol and/or triglycerides and frequently a low level of HDL cholesterol. Dyslipidemia can lead to increased risk of stroke, atherosclerosis and coronary artery disease, as well as peripheral artery disease, a narrowing of the arteries that can limit blood flow to the limbs, the legs in particular. Treatment involves dietary improvements, weight loss, increased physical activity and often, lipid-lowering pharmaceuticals. Niacin (nicotinic acid) has been shown to safely and effectively address lipid abnormalities by increasing HDL cholesterol and lowering LDL cholesterol and triglycerides.. Niacin has a proven safety record and an ability to be safely combined with statin medication. Nicotinic acid therapy can result in short-lived, but bothersome non-allergenic, dermal flushing, characterized by redness ...

When it comes to Vitamin B3, not all forms of Niacin are created equally. Aside from the risk of allergens and impurities, there are also separate forms with critical distinctions. The pure form is made solely of nicotinic acid which causes the flushing effect when it is taken by humans. The flushing effect is a redness that starts in the face and expands outwards through the rest of the body. It can make the skin feel warm, dry, and itchy for half an hour. The flushing effect is associated with vascular dilation that helps open up the tiny capillaries and blood vessels to clean out all the toxic junk they may have accumulated. Nicotinic Acid Lowers Cholesterol Nicotinic acid is also associated with increasing HDL levels in the body to prevent heart disease and plaques from accumulating on the interior walls of arteries. Nicotinic acid is also known to lower the LDL and VLDL bad cholesterols that clog up arteries and lead to heart attacks and strokes. Other Benefits of Vitamin B3 Vitamin B3 ...

BACKGROUND/AIMS: Nicotinic acid (NA), a lipid-lowering drug, serves as a source of NAD(+), the cofactor for Sirt1. Leucine (Leu) stimulates the AMPK/Sirt1 axis and amplifies the effects of other AMPK/Sirt1 activating compounds. Therefore, we tested the interactive effects of leucine and low dose NA on AMPK/Sirt1 signaling and downstream effects of lipid metabolism in cell culture, C. elegans and mice. METHODS: LDL-receptor knockout mice were fed an atherogenic Western diet supplemented with leucine (24 g/kg diet) and sub-therapeutic NA combinations (50 mg/kg diet and 250 mg/kg diet) or low therapeutic NA (1000 mg/kg diet) for 8 weeks to evaluate markers of hyperlipidemia and atherosclerosis ...

ABSTRACT OF THE DISCLOSURE The present invention relates to a process for pro-ducing coarse-crystalline high-purity nicotonic acid. In said process 3-cyano pyridine is saponified with aqueous alkali hydroxide. By adding mineral acid at temperatures of between 99 and 135°C to the alkali-nicotinate solution thus obtained the nicotinic acid is allowed to crystallize out. The pH value does not fall to 3.7 in any case.

Scientific, peer-reviewed Dermatology article, indexed with MEDLINE/PubMed: A Status Report on Topical Tazarotene in the Management of Acne Vulgaris : Tazarotene is a synthetic retinoid that, depending on the concentration and vehicle, is approved by the US Food and Drug Administration for the topical treatment of acne vulgaris (AV) and plaque psoriasis. Tazarotene is also used as adjunctive treatment for specified clinical manifestations of chronically photodamaged skin (facial fine wrinkling, mottled facial hypopigmentation and hyperpigmentation, and benign facial lentigines), along with comprehensive skin care and photoprotection from sunlight. The gel formulation was released in the United States in 1997, with the cream formulation made available in 2000. Multiple studies are available supporting the effective and safe use of topical tazarotene for each of its indications. This article provides an overview of the pharmacology of topically applied tazarotene, discussing in particular up-to-date

TY - JOUR. T1 - Effectiveness of low-dose crystalline nicotinic acid in men with low high-density lipoprotein cholesterol levels. AU - Martin-Jadraque, Raquel. AU - Tato, Federico. AU - Mostaza, Jose M.. AU - Vega, Gloria L. AU - Grundy, Scott M. PY - 1996/5/27. Y1 - 1996/5/27. N2 - Background: Hypoalphalipoproteinemia (low serum concentration of high-density lipoprotein cholesterol [HDL-C]) is a common pattern of dyslipidemia associated with coronary heart disease. High doses of nicotinic acid effectively raise HDL-C levels in this condition, but they are commonly accompanied by side effects. The efficacy of low doses of nicotinic acid that may produce fewer side effects has not been adequately studied. Objective: To determine the effects of low-dose nicotinic acid on HDL-C levels in patients with hypoalphalipoproteinemia. Methods: Forty-four men with low HDL-C levels (, 1.03 mmol/L [,40 mg/dL]) entered the study. Twenty-four patients otherwise had normal lipid levels, and 20 were moderately ...

Basal-cell nevus syndrome (BCNS) is an inherited condition marked by multiple basal cell carcinomas (BCCs) associated with several other abnormalities. Various treatment modalities have been used to eradicate these tumors. However, recurrences and scarring limit their use. A case of BCNS in which multiple BCCs were effectively treated with surgical excision and covering of the wounds with homologous glycerol-preseved skin grafts, is described. Moreover, in order to avoid recurrences, the patient was treated with topical tazarotene 0.1% cream. The patients was effectively treated with this combination therapy and minimal scarring was noted at follow-up. Homologous skin grafts and tazarotene can be used to effectively treat BCCs associated with BCNS, with minimal post-treatment scarring.. ...

Dyslipidaemia is characterized by low plasma levels of high-density lipoprotein cholesterol (HDL-c), elevated triglycerides and an increase in low density lipoprotein (LDL-c) particles, and has been unequivocally established as a most important cardiovascular risk factor. While statins are effective in reducing plasma levels of LDL-c, these drugs have only modest effects on raising HDL-c (typically by less than 10%), even with aggressive statin therapy. However, increasing evidence suggests that low HDL-c might be at least as relevant as high LDL-c in promoting the development and progression of atherosclerosis. The beneficial effect of raising HDL-c on clinical outcome has already been demonstrated by several studies.. Nicotinic acid is the most potent agent available for raising plasma levels of HDL-c by up to 29% at clinically recommended doses, and substantially lowers triglycerides and LDL-c. Furthermore, nicotinic acid is also the most potent lipid lowering agent available that reduces ...

Once the pheromone-receptors detects pheromones of another gender, the G-alpha subunit comes to action, dissociating from the GPCR complex. This protein starts a signal leading to growth arrest and to a mating response, of which the morphology is called a shmoo. To make the smelling device to detect tuberculosis, our yeast cells need a Methyl nicotinate- (the scent associated with tuberculosis) receptor. Unfortunately a methyl nicotinate receptor isnt characterized as such yet and we chose a very related ligand receptor: niacin. This receptor, due to its chimeric properties is transported to the same place as the pheromone receptor and will use the same pathway. In the end our goal is to see whether we can change this receptor through directed mutagenesis to let it smell methyl nicotinate.. To view the plasmids we have made and the accompanying experiments you can click the image below.. ...

OBJECTIVE: Nicotinic acid (NA) treatment has been associated with benefits in atherosclerosis that are usually attributed to effects on plasma lipoproteins. The NA receptor GPR109A is expressed in monocytes and macrophages, suggesting a possible additional role for NA in modulating function of these immune cells. We hypothesize that NA has the potential to act directly on monocytes to alter mediators of inflammation that may contribute to its antiatherogenic effects in vivo. METHODS AND RESULTS: In human monocytes activated by Toll-like receptor (TLR)-4 agonist lipopolysaccharide, NA reduced secretion of proinflammatory mediators: TNF-α (by 49.2±4.5%); interleukin-6 (by 56.2±2.8%), and monocyte chemoattractant protein-1 (by 43.2±3.1%) (P|0.01). In TLR2 agonist, heat-killed Listeria monocytogenes-activated human monocytes, NA reduced secretion of TNF-α (by 48.6±7.1%), interleukin-6 (by 60.9±1.6%), and monocyte chemoattractant protein-1 (by 59.3±5.3%) (P|0.01; n=7).

Dr. Ness has been taking good care of me since 1988. Last year I needed major shoulder surgery and he referred me to an orthopedic surgeon who had the same compassion and medical values as Dr. Ness. Major surgery is no picnic, but with the kind and caring support of Dr. Ness, my surgeon and the team at Woodwinds Health Campus, my recovery was faster than expected, I was able to start physical therapy sooner and get my life back to normal. I credit the success of my surgery and recovery to the relationship between Dr. Ness and I, and in him knowing not only my medical history, but knowing me as a person and providing the level of care based on that knowledge. By the way, the day after I returned home from the hospital, Dr. Ness called to see how things went and more importantly how I was doing. ...
