PURPOSE: To compare various characteristics of Xalatan(®) and five generic latanoprost ophthalmic solutions. METHODS: Drop size, volume, pH values, buffer capacity, viscosity, hardness of bottles and costs were determined. Drop sizes were measured in triplicates by micropipettes, and the number of drops counted in three separate bottles of each generic product was determined. pH values were measured in triplicates by a calibrated pH meter. Buffer capacity was exploited by titrating known quantities of strong base into 2...

BACKGROUND: Prescription drug spending is a significant component of Medicaid total expenditures. The Affordable Care Act (ACA) includes a provision that increases the Medicaid rebate for both brand-name and generic drugs. This study examines the extent to which oncology drug prices changed after the increase in the Medicaid rebate in 2010. METHODS: A pre-post study design was used to evaluate the correlation between the Medicaid rebate increase and oncology drug prices after 2010 using 2006-2013 State Drug Utilization Data...

A case-control study was conducted in 2013 to investigate the use of pituitary-derived hormones from sheep as a potential risk factor for the presence of atypical scrapie in Great Britain sheep holdings. One hundred and sixty-five holdings were identified as cases. Two equal sets of controls were selected: no case of scrapie and cases of classical scrapie. A total of 495 holdings were selected for the questionnaire survey, 201 responses were received and 190 (38.3 per cent) were suitable for analysis. The variables 'use-of-heat-synchronisation/superovulation' and 'flock size' were significantly associated with the occurrence of atypical scrapie...

BACKGROUND: Governments in both developed and developing countries have adopted generic drug substitution policies to decrease pharmaceutical expenditures and improve access to medicine. In August 2015, the Ministry of Public Health (MOPH) in Lebanon introduced generic drug substitution and a unified medical prescription form as policy instruments to promote generic drug use. The objective of this exploratory study was to examine the attitudes of community pharmacists and the reported practices in relation to the implementation of the new generic drug substitution policy...

BACKGROUND: Potentially inappropriate medication (PIM) is defined as medication with uncertain therapeutic effects and/or potential adverse drug reactions outweighing the clinical benefits. The prescription rate of PIM for oldest-old patients is high despite the existence of lists of PIM (e.g. the PRISCUS list) and efforts to raise awareness. This study aims at identifying general practitioners' views on PIM and aspects affecting the (long-term) use of PIM. METHODS: As part of the CIM-TRIAD study, we conducted semi-structured, qualitative interviews with 47 general practitioners, discussing 25 patients with and 22 without PIM (according to the PRISCUS list)...

The introduction of generic antiretroviral medications in developing countries has resulted in significant CD4 cell restoration, HIV viral decline, and a noteworthy reduction in the time to initiation of therapy. Projection models have also predicted significant cost saving associated with the extensive diffusion of generic antiretrovirals in developed countries. However, some uncertainties on generics have recently been raised. These concerns mainly relate to the adequacy of the study design for bioequivalence testing, the potential for uncontrolled switching from one generic to another, and the loss of adherence if patients switched from fixed-dose coformulations to single components in order to incorporate the new generic drugs...

Paternal environmental conditions can influence phenotypes in future generations, but it is unclear whether offspring phenotypes represent specific responses to particular aspects of the paternal exposure history, or a generic response to paternal 'quality of life'. Here, we establish a paternal effect model based on nicotine exposure in mice, enabling pharmacological interrogation of the specificity of the offspring response. Paternal exposure to nicotine prior to reproduction induced a broad protective response to multiple xenobiotics in male offspring...

In the past decade, the standards of clinical trials in China have moved closer to international standards, thus encouraging the development of innovative drugs. However, a large backlog of pending applications for both drug approval and clinical trial registration has arisen owing to the complexity of the approval process, the volume of applications and a lack of staff available to process these applications, among other reasons. To improve the drug approval process, a 'four-colour-light' strategy was introduced...

To contain pharmaceutical spending, drug budgets have been introduced across health systems. Apart from analyzing whether drug budgets fulfill their overall goal of reducing spending, changes in the cost and quality of prescribing and the enforcement mechanisms put in place need evaluation to assess the effectiveness of drug budgets at the physician level. In this study, we aim to analyze the cost and quality of prescribing conditional on the level of utilization of the drug budget and in view of varying levels of enforcement in cases of overspending...

Modification of cellular macromolecules by reactive drug metabolites is considered to play an important role in the initiation of tissue injury by many drugs. Detection and identification of reactive intermediates is often performed by analyzing the conjugates formed after trapping by glutathione (GSH). Although sensitivity of modern mass spectrometrical methods is extremely high, absolute quantification of GSH-conjugates is critically dependent on the availability of authentic references. Although (1)H NMR is currently the method of choice for quantification of metabolites formed biosynthetically, its intrinsically low sensitivity can be a limiting factor in quantification of GSH-conjugates which generally are formed at low levels...

Recent breakthrough in stroma-reprogrammed combinatorial therapy (SRCT) for pancreatic tumor opens a new route for improving conventional chemotherapeutic efficacy, which utilizes VDR ligand to reprogram activated stromal cells in stiffened microenvironment, leading to reduced 'barrier effects' and increased tissue-infiltration of the chemotherapy drug. As a novel therapeutic strategy and mechanism of action, the progress of SRCT relies on tailored in vitro drug assessment platforms to further optimize its efficacy and extend to applications in other tumor types...

The phenomenon of recovering the permanent shape from a severely deformed temporary shape, but only in the presence of the right stimulus, is known as the shape memory effect (SME). Materials with such an interesting effect are known as shape memory materials (SMMs). Typical stimuli to trigger shape recovery include temperature (heating or cooling), chemical (including water/moisture and pH value), and light. As a SMM is able not only to maintain the temporary shape but also to respond to the right stimulus when it is applied, via shape-shifting, a seamless integration of sensing and actuation functions is achieved within one single piece of material...

The new drugs delamanid and bedaquiline are increasingly being used to treat multidrug-resistant (MDR-) and extensively drug-resistant tuberculosis (XDR-TB). The World Health Organization, based on lack of evidence, recommends their use under specific conditions and not in combination. No systematic review has yet evaluated the efficacy, safety, and tolerability of delamanid and bedaquiline used in combination. A search of peer-reviewed, scientific evidence was carried out, aimed at evaluating the efficacy/effectiveness, safety, and tolerability of delamanid and bedaquiline-containing regimens in individuals with pulmonary/extrapulmonary disease, which were bacteriologically confirmed as M/XDR-TB...

We test the effect of the introduction of Medicare Part D on physician prescribing behavior by using data on physician visits from the National Ambulatory Medical Care Survey (NAMCS) 2002-2004 and 2006-2009 for patients aged 60-69. We use regression discontinuity designs to estimate the effect of part D around the age of 65 before and after 2006 and then compare the discrete jump in outcomes at age 65 before and after Part D. We find a 32% increase in the number of prescription drugs prescribed or continued per visit and a 46% increase in the number of generic drugs prescribed or continued for the elderly after the introduction of Medicare Part D...

REVIEW
Shannon Chang, Stephen Hanauer
Infliximab and adalimumab biosimilars have been approved by the FDA and European Medicines Agency and have already been introduced to the international market. Availability into the US market is imminent. Biosimilars are highly similar to the reference biologic product but should not be referred to as, nor equated with, generic medications as no two biosimilars can ever be identical. Regulatory pathways for biosimilar approval consider the totality of evidence for biosimilar approvals, but the preponderance of development relies on analytic and functional testing and allows extrapolation between indications to reduce the financial burden of completing comparative clinical trials for each indication...
