Despite many benefits including simple point-of-care sample collection, reduced costs, and simplified shipping and storage, dried blood spot (DBS) techniques have faced adoption resistance such as the hematocrit (Hct) effects and the established preference for bioanalysis of plasma rather than whole blood. One way to potentially circumvent these challenges is to adopt the concept of a dried plasma spot (DPS) technique. One approach to accomplishing this is through an on-card red blood cell (RBC) filtration to generate plasma from whole blood without the need for centrifugation...

Phentermine is the most widely prescribed obesity medication in adults, yet studies of its use in the pediatric population are limited. We conducted a retrospective chart review of adolescents with obesity treated in a pediatric weight management clinic to examine the weight loss effectiveness of phentermine added to standard of care lifestyle modification therapy (SOC) versus SOC alone. All patients receiving phentermine plus SOC (n=25) were matched with a comparison group receiving only SOC (n=274). Differences at 1, 3, and 6 months were evaluated using generalized estimated equations adjusting for age, sex, and baseline body mass index (BMI) and robust variance standard error estimates for confidence intervals and P-values...

Obesity is a global epidemic that contributes to a number of health complications including cardiovascular disease, type 2 diabetes, cancer and neuropsychiatric disorders. Pharmacotherapeutic strategies to treat obesity are urgently needed. Research over the past two decades has increased substantially our knowledge of central and peripheral mechanisms underlying homeostatic energy balance. Homeostatic mechanisms involve multiple components including neuronal circuits, some originating in hypothalamus and brain stem, as well as peripherally-derived satiety, hunger and adiposity signals that modulate neural activity and regulate eating behavior...

Few studies on combination therapies for the treatment of obesity had been conducted until recently, when two fixed-dose combinations, bupropion-naltrexone ER fixed-dose combination and phentermine-topiramate ER titrated-dose combinations were evaluated in clinical studies that ultimately led to FDA approval. Areas covered: In this review, we discuss safety concerns about both combinations, the rationale and history of combination therapies for obesity (including phentermine plus fenfluramine), and possible future new combinations...

The homeostatic controls over eating are inextricably linked to the reward aspects of eating. The result is an integrated response that coordinates the internal milieu with the prevailing environment. Thus, appetite, which reflects a complex interaction among the external environment, behavioral profile, and subjective states as well as the storage and metabolism of energy, has an important role in the regulation of energy balance. In the prevailing food environment which offers an abundance of food choices it is likely that the motivation to consume from a wide range of delectable foods plays a greater role in contributing to overeating than in the past when the motivation to eat was largely governed by metabolic need...

Obesity is a common condition that is associated with numerous medical problems such as cardiovascular disease, pulmonary disease, and diabetes mellitus. Primary care physicians have an important role in helping patients develop a successful weight loss plan to improve their overall health. Dietary strategies emphasizing reduced caloric intake, regardless of the nutrient composition, are important for weight loss. Behavioral interventions such as motivational interviewing and encouraging physical activity lead to additional weight loss when combined with dietary changes...

The recent approval of liraglutide, lorcaserin, naltrexone/bupropion extended-release, and phentermine/topiramate extended-release, brings the number of medications for long-term weight loss to 5 (including orlistat). Indicated for the treatment of patients with overweight (body mass index [BMI] ≥27 kg/m2 with ≥1 weight-related comorbidity) or obesity (BMI ≥30 kg/m2), these medications provide new opportunities to address this burgeoning health problem.

The global obesity epidemic and its impact on cardiovascular outcomes is a topic of ongoing debate and investigation in the cardiology community. It is well known that obesity is associated with multiple cardiovascular risk factors. Although life-style changes are the first line of therapy, they are often insufficient in achieving weight loss goals. Liraglutide, naltrexone/bupropion, and phentermine/topiramate are new agents that have been recently approved to treat obesity, but their effects on cardiovascular risk factors and outcomes are not well described...

Nonmedical use of prescription stimulants such as phentermine (PT) has been regulated by law enforcement authorities due to its euphorigenic and relaxing effects. Due to high potential for its abuse, reliable analytical methods were required to detect and identify PT and its metabolite in biological samples. Thus a dilute and shoot liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was developed and validated for simultaneous determination of PT, N-hydroxyphentermine (NHOPT) and mephentermine (MPT) in urine...

Obesity is growing at an alarming rate with huge consequences on health and economy. The worldwide prevalence of obesity has nearly doubled in 30 years. Obesity causes many physiological dysfunctions that affect nearly every organ producing multiple morbidities. Despite these facts, there is still no clear, well-defined solution. Notwithstanding the devastating prevalence and consequences of obesity, today only five medicines, orlistat, lorcaserin, phentermine-toprimate, bupropion-naltrexone and liraglutide, are approved by the FDA for long-term treatment of obesity...

The presented analysis was performed to characterize the relationship between treatment-related early (week 4) and longer-term (3-6 months) weight loss to understand the potential utility of 4-week proof-of-mechanism studies in the early decision-making process during clinical development of new anti-obesity compounds. A regression-based meta-analysis was performed leveraging publically available clinical outcomes data to (i) characterize the within-trial relationship between treatment-related early and longer-term body weight loss, (ii) identify and quantify key covariate effects on this relationship...

A workflow overcoming microsample collection issues and hematocrit (HCT)-related bias would facilitate more widespread use of dried blood spots (DBS). This report describes comparative results between the use of a pipet and a microfluidic-based sampling device for the creation of volumetric DBS. Both approaches were successfully coupled to HCT-independent, fully automated sample preparation and online liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) analysis allowing detection of five stimulants in finger prick blood...

Weight-loss medications have been associated with many conditions, including valvular heart disease, ischemic colitis, and pulmonary hypertension. There is a constant increase in the use of these drugs, especially new medications with better efficacy. Phentermine is one such drug, approved for short-term use to lose weight. We report a case of ischemic colitis in a female patient linked to inappropriate phentermine intake. The patient presented with symptoms of severe abdominal pain and repeated bowel movement associated with rectal bleeding for two weeks...

Five pharmaceutical strategies are currently approved by the US FDA for the treatment of obesity: orlistat, lorcaserin, liraglutide, phentermine/topiramate, and bupropion/naltrexone. The most effective treatment seems to be the combined administration of phentermine/topiramate followed by lorcaserin and bupropion/naltrexone. In relation to the management of excessive weight, other aspects also need to be considered, including comorbidities accompanying obesity, drug interactions, and the risk of negative collateral effects, as well as individualized treatments based on the genetic make-up...

The focus of this paper is treatment of obesity in relation to the management of hedonic appetite. Obesity is a complex condition which may be potentiated by excessive reward seeking in combination with executive functioning deficits that impair cognitive control of behavior. Stimulant medications address both reward deficiency and enhance motivation, as well as suppressing appetite. They have long been recognized to be effective for treating obesity. However, stimulants can be abused for their euphoric effect...
