Palliative care cancer patients are treated with many drugs especially at the end of life. Limiting of polypharmacy a decreases the risk of associated adverse effects, medical errors and harmful drug interactions The time lag to benefit of many medications used for cardiovascular diseases or risk factors like hypertension, hypercholesterolemia is frequently longer than palliative care cancer patient's life expectancy. It is ethically appropriate to modify, even to discontinue cardiovascular pharmacotherapy when there is no prospect of benefit...

PURPOSE OF REVIEW: Dyslipidaemias are a major risk factor for cardiovascular disease (CVD); in particular, high levels of low-density lipoprotein cholesterol (LDL-C) have been associated to a higher cardiovascular risk. Reducing LDL-C levels decreases the risk of coronary heart disease (CHD), and the greater the LDL-C reduction, the greater the decrease in cardiovascular risk. Although statins represent the first line lipid-lowering therapy, many patients do not reach the recommended goals or exhibit adverse side effects leading to therapy discontinuation; in addition, a significant percentage of statin-treated patients continue to experience cardiovascular events even in the presence of well controlled LDL-C levels, because of alterations in other lipid/lipoprotein classes, including triglycerides and high-density lipoprotein cholesterol...

BACKGROUND: The population of patients with established coronary artery disease (CAD) is growing because of an improvement in outcomes and survival from acute disease episodes. Nevertheless, these patients remain at high risk of cardiovascular events. Thus, CAD management is important in prevention of disease progression. The objective of this analysis was to describe disease management and clinical outcome of Austrian outpatients with stable CAD over 5 years by using data from the international CLARIFY registry...

Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease affecting the upper and lower motor neurons in the motor cortex and spinal cord. Abnormal accumulation of mutant superoxide dismutase I (SOD1) in motor neurons is a pathological hallmark of some forms of the disease. We have shown that the orderly progression of the disease may be explained by misfolded SOD1 cell-to-cell propagation, which is reliant upon its active endogenous synthesis. Reducing the levels of SOD1 is therefore a promising therapeutic approach...

PURPOSE OF REVIEW: Although lipid-lowering treatment with statins, ezetimibe, and PCSK9 inhibitors is a very successful strategy to prevent cardiovascular events, there is a need for further drug developments. Not all patients respond sufficiently to the available therapy (very high baseline values, intolerance). Furthermore, patients may be characterized by dyslipidemias not accessible to available drugs such as patients with homozygous familial hypercholesterolemia, chylomicronemia syndrome, or elevated lipoprotein(a)...

The goal of this study was to prepare sustained release microparticles for methyl blue and aspartame as sparingly and freely water-soluble model drugs by lipid film coating in a Mini-Glatt fluid bed, and to assess the effect of coating load of two of lipids, hard fat and glyceryl stearate, on the release rates. 30g drug-loaded mannitol carrier microparticles with average diameter of 500 or 300μm were coated with 5g, 10g, 20g and 30g lipids, respectively. The model drugs were completely released in vitro through pores which mainly resulted from dissolution of the polyol core beads...

INTRODUCTION: Atorvastatin is the most widely used statin world-over. Although atorvastatin is beneficial in reducing cardiovascular morbidity and mortality, they are associated with Adverse Drug Reactions (ADRs) which are under-recognized as well as under-reported. There is no data on safety of atorvastatin in ethnic populations like South Indian Tamils and hence the need for this study. AIM: To report the Adverse Events (AEs) associated with atorvastatin use, their causality and severity in dyslipidemic south Indian Tamils...

In this study, paclitaxel and etoposide-loaded lipid-polymer hybrid nanoparticles (PE-LPN) was successful prepared and evaluated for physicochemical and anticancer effect. Nanosized PE-LPN was obtained with a perfect spherical morphology. PE-LPN exhibited a controlled release of two drugs in a sequential manner. The nanoparticles exhibited a typical endocytosis-mediated cellular uptake in cancer cells. The ratiometric combination of paclitaxel (PTX) and etoposide (ETP) were significantly more cytotoxic than individual drugs...

Lipid-based particles are used worldwide in clinical trials as carriers of hydrophobic paclitaxel (PTXL) for cancer chemotherapy, albeit with little improvement over the standard-of-care. Improving efficacy requires an understanding of intramembrane interactions between PTXL and lipids to enhance PTXL solubilization and suppress PTXL phase separation into crystals. We studied the solubility of PTXL in cationic liposomes (CLs) composed of positively charged 2,3-dioleyloxypropyltrimethylammonium chloride (DOTAP) and neutral 1,2-dioleoyl-sn-glycero-3-phosphatidylcholine (DOPC) as a function of PTXL membrane content and its relation to efficacy...

St. John's wort (SJW) is a common medicinal herb used for the treatment of mild to moderate depression. Hyperforin, one of the chief components of SJW, plays an important role in the induction of cytochrome P450 enzymes (CYP) and P-glycoprotein transporter (P-gp), and therefore, affects the pharmacokinetics of various drugs. There are several clinical studies demonstrating the interaction of SJW with the metabolism of conventional drugs which may cause life-threatening events. Areas covered: This review focuses on human studies that have evaluated pharmacokinetic alterations of conventional drugs in concomitant use with different SJW preparations...

BACKGROUND: Type II diabetes mellitus (T2DM) is complicated by multiple cardio-metabolic risk factors. Controlling these factors requires lifestyle modifications alongside utilisation of anti-diabetic medications. Different glucose lowering [(biguanides (BIGs), sulfonylureas (SUAs), thiazolidinediones (TNZ)], lipid lowering (statins), and anti-hypertensive medicines [angiotensin converting enzyme inhibitors (ACEIs), calcium channel blockers (CCBs), angiotensin II receptor blockers (ARBs) and central acting drugs (CADs)] have been approved for controlling hyperglycaemia, dyslipidaemia and hypertension respectively...

The radix of Scutellaria baicalensis (SB) is a herb widely used in traditional Chinese medicine to treat metabolic diseases. Several main components, including baicalin and wogonoside, possess anti-dyslipidemia, anti-obesity and anti-diabetic effects. We hypothesized that co-administration of SB extract and metformin exerts a better effect on obesity-induced insulin resistance and lipid metabolism than treatment with metformin alone. We compared the effect of metformin (100 mg/10 mL/kg/day) alone with co-administration of metformin (100 mg/5 mL/kg/day) and SB extract (200 mg/5 mL/kg/day) on Otsuka Long Evans Tokushima Fatty rats, a useful model of type II diabetes with obesity, and used Long-Evans Tokushima Otsuka rats as a control...

BACKGROUND: Lipid emulsion treatment appears to have application in the treatment of local anesthetic-induced cardiac arrest. To examine whether the efficacy of lipid resuscitation in the treatment of local anesthetic-induced cardiac arrest is affected by lipophilicity, the effects of lipid infusions were compared between levobupivacaine-induced (high lipophilicity) and ropivacaine-induced (lower lipophilicity) rat cardiac arrest model. METHODS: A total of 28 female Sprague-Dawley rats were anesthetized using sevoflurane, which subsequently underwent tracheostomy, followed by femoral artery and vein cannulation...

A class of pseudopeptides based on poly(lysine iso-phthalamide) backbone have emerged as promising drug delivery candidates due to their pH activated membrane disruption ability. In order to gain molecular understanding on these novel polymeric species, we have constructed force field parameters and simulated the behaviours of polymers with and without phenylalanine grafted as side chains at conditions compatible with different pH. The free energy changes upon polymer permeation through membrane were calculated using the umbrella sampling technique...

A randomized clinical trial showed the beneficial effects of the selective peroxisome proliferator-activated receptor (PPAR)-α agonist, fenofibrate, in reducing the progression of diabetic retinopathy independent of serum lipid levels. All subtypes of PPAR (PPAR-α, PPAR-γ, and PPAR-β/δ) have been reported to play a key role in microvascular inflammation and angiogenesis. Therefore, the agonistic function of fenofibrate against the PPAR-α has been suggested to contribute to its medicinal effect. Furthermore, bezafibrate is a fibrate drug commonly used as a lipid-lowering agent to treat hyperlipidemia and acts as a pan-agonist of all PPARs subtypes...

BACKGROUND: Hypertension is one of the primary modifiable risk factors for cardiovascular disease. Adequate vitamin D (vit D) levels have been shown to reduce vascular smooth muscle contraction and to increase arterial compliance, which may be beneficial in hypertension. Further, coenzyme Q10 (COQ10) through its action to lower oxidative stress has been reported to have beneficial effects on hypertension and heart failure. This study examined the possible cardiac and renal protective effects of vit D and COQ10 both separately and in combination with an angiotensin II receptor blocker, valsartan (vals) in l-NAME hypertensive rats...

Coronary Artery Disease (CAD) is a major killer disease throughout the world. Dyslipidemia is a major contributor to the risk of CAD. Several dietary articles traditionally used in India and other South Asian countries reduced dyslipidemia. The present study was undertaken to evaluate the combined effect of Mung bean (Vigna radiata) and Elephant foot yam (Amorphophallus paeoniifolius) on serum lipids and atherogenic indices in albino rats and to compare it with a standard drug Cholestyramine. Thirty healthy albino rats of both sexes (150-200 g) were randomized to 5 groups of 6 animals each...

PPARα and PPARγ have been the most widely studied Peroxisome Proliferator-Activated Receptor (PPAR) subtypes due to their important roles in regulating glucose, lipids and cholesterol metabolism. By combining the lowering serum triglyceride levels benefit of PPARα agonists (such as fibrates) with the glycemic advantages of the PPARγ agonists (such as TZD), the dual PPAR agonists approach can both improve the metabolic effects and minimize the side effects caused by either agent alone, and hence has become a promising strategy for designing effective drugs against type-2 diabetes...
