Hence, it is essential to develop an efficient analytical method which could be useful for the separation, identification and characterization of all possible degradation products of drug. Macitentan (MT) is an endothelin receptor antagonist (ERA) drug used to treat high blood pressure in the ...
Synthetic urine (SU), which was primarily utilized by drug testing laboratories as matrix for quality control preparations, are now commercially sold and can be used to "fool" a positive drug test. To determine if SU can pass as authentic urine, we challenged Army urine drug testing collection and testing procedures using eight different commercial SU products. Adulteration (Sciteck AdultaCheck® 6) and Onsite SU (Synthetic UrineCheck ) test strips were also evaluated. Five of the eight SU were identified b...
The US Food and Drug Administration approval of the first 3D printed tablet in 2015 has ignited growing interest in 3D printing, or additive manufacturing (AM), for drug delivery and testing systems. Beyond just a novel method for rapid prototyping, AM provides key advantages over traditional manufacturing of drug delivery and testing systems. These includes the ability to fabricate complex geometries to achieve variable drug release kinetics; ease of personalising pharmacotherapy for patient and lowering t...

In the USA, drugs are approved by the FDA by three main regulatory pathways: (i) 505(b)(1) new drug applications (NDAs); (ii) 505(b)(2) NDAs; and (iii) 505(j) abbreviated NDAs (ANDAs). The appropriate pathway depends on the active ingredient, already approved drug products, drug formulation, clinical indication, route of exposure, among other factors. The 505(b)(2) NDA pathway is a regulatory approval pathway that allows sponsors to use existing public data in lieu of conducting studies; thus, potentially o...
Praziquantel (PZQ) is an inexpensive, low toxicity BCS II class anthelmintic drug used for the treatment of neglected tropical diseases. In earlier papers a mechanochemical activation has been used to induce physical transformations on the drug which would ameliorate its solubility and hence its bioavailability and a systematic study of the effects of varying temperature, frequency and time of milling on drug melting enthalpy and drug recovery was given. In this communication, the focus is on the degradatio...
The USP Apparatus 3 is a compendial dissolution Apparatus that has been mainly used to assess the performance of modified-release drug products. However, this Apparatus can be applied to dissolution testing of immediate-release tablets as well, with several advantages such as lower consumption of dissolution media, reduced setup time in quality control routine, and minimized hydrodynamic issues. In this work, three immediate-release (IR) tablets containing antihypertensive drugs of different Biopharmaceutic...
The goal of this study was to establish and compare baseline data on the prevalence of gabapentin identified through postmortem toxicology testing among drug overdose decedents in several geographically diverse states/jurisdictions with differing levels of drug overdose fatality burdens in 2015.
Juvenile animal testing has become an established part of drug development to support safe clinical use in the human pediatric population and for eventual drug product label use.
The societal impact of drug use is well known. An example is when drug-intoxicated drivers increase the burden on policing and healthcare services.
Current practices for viability testing of cryopreserved cord blood products: an international survey by the cellular therapy team of the Biomedical Excellence for Safer Transfusion (BEST) Collaborative.
Viability testing is a common practice in laboratories. The goal of this study was to ascertain current laboratory practices internationally for performing viability testing for cryopreserved cord blood (CB) products and glean information about how to standardize the method to improve interlaboratory reproducibility.
To assess drug quality and pharmaceutical care in South Africa, "mystery" (i.e. anonymous) customers collected 316 samples from July to September 2016. Solid dosage forms containing amoxicillin alone or in combination with clavulanic acid as well as analgesics containing paracetamol alone or in combination were sampled in a randomized fashion from the formal market (pharmacies) and by convenient sampling from the informal market. Visual inspection, uniformity of dosage units and dissolution testing were per...
Tuberculosis (TB) caused by Mycobacterium tuberculosis (MTB) is the deadliest infectious disease and the associated global threat has worsened with the emergence of drug resistance, in particular multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB). Although the World Health Organization (WHO) End-TB Strategy advocates for universal access to antimicrobial susceptibility testing, this is not widely available and/or it is still underused. The majority of drug resistance in clinical MTB ...
Bioequivalence implementation in developing countries where a high proportion of similar drug products are being marketed has found several obstacles, impeding regulatory agencies to move forward with this policy. Biopharmaceutical quality of these products, several of which are massively prescribed, remains unknown. In this context, an in vitro-in silico-in vivo approach is proposed as a mean to screen product performance and target specific formulations for bioequivalence assessment. By coupling in vitro ...
Forced degradation studies on aliskiren were carried out according to ICH and WHO guidelines. Six degradation products were formed in total in the solution state. Their separation among themselves and from the drug was successfully achieved on a C-18 column utilizing acetonitrile and phosphate buffer (pH 3.0) in the mobile phase, which was run in a gradient mode. To characterize them, a complete mass fragmentation pathway of the drug was first established with the help of MS/TOF and MS data. This was foll...
Non-disclosure of drug use on surveys is common and many drug users unknowingly ingest adulterant or replacement drugs, which leads to underreporting of use of these drugs. Biological testing can complement survey research, and hair-testing is an appealing method as many drugs are detectable for months post-use. We examined willingness to donate a hair sample to be tested among those surveyed in a population at high risk for consuming adulterated drugs-electronic dance music (EDM) party attendees.
Large-scale studies of Drug Provocation Testing (DPT) or Rapid Drug Desensitization (RDD) for hypersensitivity to antineoplastics and biologicals are scarce and limited to a few institutions OBJECTIVE: Our aim was to review our experience with DPT and RDD in a large number of patients with a history of hypersensitivity to antineoplastics and biologicals and summarize the practical implications of that experience.
To address issues such as transportation and the time-consuming nature of tissue-engineered liver for use as an effective drug metabolism and toxicity testing model, "ready-to-use" cryogenic tissue-engineered liver needs to be studied. The research developed a cryogenic tissue-engineered liver slice (TELS), which comprised of HepG2 cells and calcium alginate gel. Cell viability and liver-specific functions were examined after different cryopreservation and recovery culture times. Then, cryogenic TELSs were ...
Culture-based assays are currently the gold standard for drug susceptibility testing (DST) for Mycobacterium tuberculosis. They provide good sensitivity and specificity, but are time-consuming. The objective of this study was to evaluate whether whole genome sequencing (WGS), combined with software tools for data analysis, can replace routine culture based assays for drug susceptibility testing of M. tuberculosis.
