Brand-Name Medications vs Available Generic Alternatives
In December 1996, 8 days before Christmas, the US Food and Drug Administration (FDA) approved Lipitor (atorvastatin; Pfizer) for the treatment of hyperlipidemia. Lipitor would become one of the most profitable prescription drugs in history, bringing in $130 billion in sales during its lifetime as a brand-name product and peaking at nearly $13 billion in sales in 2006 alone. Lipitor was far from the first statin in its class (simvastatin, pravastatin, and fluvastatin were already on the market), but 1996 was also the year that the FDA began allowing direct-to-consumer broadcast advertising. Lipitor was aggressively marketed...

A New Level A Type IVIVC for the Rational Design of Clinical Trials Toward Regulatory Approval of Generic Polymeric Long-Acting Injectables
Abstract Chronic neuropsychiatric disorders and diabetes mellitus affect millions of patients and require long-term supervision and expensive medical care. Although repeated drug administration can help manage these diseases, relapses and re-hospitalization owing to patient non-adherence and reduced therapeutic efficacy remain challenging. In response, long-acting injectables, which provide sustained drug release over longer periods at concentrations close to therapeutic ranges, have been proposed. Recent advancements include polymeric long-acting injectables (pLAIs), in which the active pharmaceutical ingredient ...

Review: Stent Fracture in the Drug-Eluting Stent Era
Stent fracture has been recognized as one cause of stent failure and has been associated with in-stent restenosis and stent thrombosis, even in 2nd-generation drug-eluting stents. Given the wide use of drug-eluting stents and paucity of contemporary data available concerning stent fracture, we reviewed clinical studies and the Food and Drug Administration's Manufacturer and User Device Experience (MAUDE) database to analyze the current trends, mechanisms, predictors, outcomes and treatment for stent fracture.

Challenges in Measuring Cost and Value in Oncology: Making It Personal
Oncology patients often find themselves facing an incurable disease with limited treatment options and increasing patient fragility. The importance of patient preferences and values increases in shared decision making especially when the cost of cancer care is continuing its steep rise. As our understanding of cancer systems biology increases, we are justifiably optimistic about therapeutic improvements but recognize that this has complicated the traditional Food and Drug Administration approval of drug indications based on organ-specific cancer for a particular drug.

Cantharidin in Dermatology.
Abstract Cantharidin is natural toxin produced by the blistering beetle. It has both vesicant and keratolytic features by inducing acanthloysis through targeting the desmosomal dense plaque, leading to detachment of the desmosomes from the tonofilaments. There are two available liquid preparations for dermatologic use, Canthacur (0.7% cantharidin) and Canthacur PS (1% cantharidin 30%/salicylic acid/2% podophylotoxin). The former preparation is indicated for the treatment of common warts, periungual warts, and molluscum contagiosum, while the more potent latter preparation is indicated only for plantar warts.

More and more evidence indicates that mefloquine potentially causes long-term mental health problems.1 And the U.S. Food and Drug Administration has recently added a boxed warning to mefloquine, advising of the possibility of neurologic and psychiatric adverse events even after drug withdrawal. We are quite sympathetic to Dr. Nevin’s proposals of considerations in the repositioning of mefloquine for an anesthetic. However, we have our own opinion about considering mefloquine, or its ameliorated form, as a potential analgesic candidate in the future. (Source: Anesthesiology)

Prescribing Medications for Pain Relief: Doctors, Patients, and Federal Regulators
In a recent New York Times editorial titled “The Opioid Epidemic We Failed to Foresee,” David A. Kessler, MD, former commissioner of the U.S. Food and Drug Administration from 1990 to 1997, argued that one of the biggest mistakes of modern medicine was its failure to appreciate the addictive nature of opioid analgesics (1). Dr. Kessler referred to a campaign by the pharmaceutical industry in the 1990s to push the idea that patients would not develop an addiction to opiate use no matter how long they took them.

[Editorial] Self-medicating in the opioid crisis
On June 7, the US Food and Drug Administration released a drug safety notice about loperamide, an anti-diarrhoea medicine sold over the counter and under prescription. The drug is being used as a cheap and legally-available high, and to reduce the symptoms of opioid withdrawal. A standard dose for the medicine is 8 mg per day in divided doses, but opioid users have been taking massive doses of the drug, as much as 300 mg or more daily for weeks at a time. Taken in such high quantities, overdoses of loperamide can cause severe heart problems like ventricular arrhythmias, cardiac arrest, and death. (Source: LANCET)

Biosimilars: Extrapolation for oncology
Biologics are essential and widely used in cancer treatment as therapeutic agents (e.g., monoclonal antibodies [mAbs]) and as supportive care agents (e.g., growth factors). Because biologics are inherently variable complex molecules that are produced through manufacturing processes in living cells, they cannot be duplicated identically to a level typically possible for small molecule drugs. Hence, the term “biosimilar” is used to describe a biologic that is highly similar to a licensed biologic product (the reference product) (European Medicines Agency, 2014; US Food and Drug Administration, 2015; World Health Organiza...
