Biosimilars are biological drug products that are highly similar to reference products in analytic features, pharmacokinetics and pharmacodynamics, immunogenicity, safety and efficacy. Biosimilar epoetin received US Food and Drug Administration (FDA) approval in 2018 [1]. The manufacturer received an FDA non-approval letter in 2017, despite receiving a favourable review by the FDA’s Oncologic Drugs Advisory Committee (ODAC) and an FDA non-approval letter in 2015 for an earlier formulation.

Background: Convenient access to prescription drugs produced outside the US has been facilitated by the Internet. Of greatest concern to clinicians and policy-makers is product quality and patient safety. The Food and Drug Administration has issued warnings to potential buyers that the safety of drugs purchased through the Internet cannot be guaranteed and may present consumers with a health risk from substandard products. Objective: To determine whether generic simvastatin tablets and capsules obtained via the Internet from international markets are equivalent to the US innovator product regarding major aspects of pharmaceutical quality. Methods: Twenty simvastatin tablets and capsules were obtained for pharmaceutical analysis: 19 generic samples from international Internet pharmacy Web sites and the US innovator product. Tablet samples were tested according to US Pbarmacopeial (USP) guidelines where applicable, using high-performance liquid chromatography, disintegration, dissolution, weight variation, hardness, and assessment of physical characteristics. These tests are often used to detect formulation defects of drug products during the manufacturing process. Results: Several international samples analyzed were not comparable to the US product in one or more aspects of quality assurance testing, and significant variability was found among foreign-made tablets themselves. Five samples failed to meet USP standards for dissolution and 2 for content uniformity. Among all samples, variability was observed in hardness, weight, and physical characterization. Conclusions: Results suggest that manufacturing standards for the international generic drug products compared with the US innovator product are not equivalent with regard to quality attributes. These findings have implications for safety and effectiveness that should be considered by clinicians to potentially safeguard patients who choose to purchase foreign-manufactured drugs via the Internet.

Counterfeit and diverted drugs are a growing problem not only in the US drug distribution supply chain but also in similar drug distribution supply chains the world over. These systems are being infiltrated by a growing trend in the illegal trade of pharmaceuticals, the result of activities of unscrupulous drug wholesalers, rogue Internet sites, foreign pharmacies, and organized criminal elements, all of which are motivated by huge profits. Efforts must be taken and new paradigms implemented on many fronts that will ultimately lead to maintaining the integrity of drug products and their packaging, securing the movement and safety of drug products as they travel through the US drug distribution supply chain. In addition, enhancing regulatory oversight and enforcement, increasing penalties for counterfeiters and drug diverters, advocating and pursuing heightened vigilance and awareness of counterfeit and diverted drugs, and increasing international collaboration are avenues that will aid in combating drug diversion and counterfeiting. This article will address several topics pertaining to drug wholesale distribution practices and how avenues for counterfeit and diverted drugs can permeate this process, notably through the secondary or shadow or gray drug market. Discussion will also highlight the emergence of Florida's drug pedigree laws and what were the goals to be obtained through enhanced legislative and enforcement action since 2003, coupled with the current state of these pedigree laws today as a result of action emanating from the 2006 Florida legislature (notably House bills HB371 and HB1540). Trends and developments in these major areas will be reviewed, with some analysis rendered noting strengths and areas of remaining weakness that require additional attention in the ongoing battle to stem the tide of drug diversion and counterfeiting, both nationally and within the state of Florida.
