ClinCalc DrugStats 2021 Update – The Most Commonly Prescribed Drugs in the United States

ClinCalc has released this year’s update to the DrugStats database — “The Top 200 Drugs of 2019”. DrugStats provides free access to prescription drug utilization data estimates for the United States.  Using this data set, users can identify trends in prescribing practice and an official, reputable “top 200 drugs” list based on data provided by the U.S. Government.

Where does the DrugStats data come from?

All medication utilization data comes from the annual Medical Expenditure Panel Survey (MEPS), a survey conducted by the Agency for Healthcare Research and Quality (AHRQ) via the United States government. This data is publicly available on the MEPS website for free.  In order for the ClinCalc DrugStats database to implement the MEPS data, basic data sanitization and standardization measures are necessary to maintain an accurate and reliable data set.  Read more about the data set by clicking here.

Add Brand/Generic Drug Names to Microsoft Office Word with the ClinCalc DrugSpell Dictionary File

By default, Microsoft Word and other Office products do not contain brand and generic medication names within the spelling dictionary.  For healthcare providers who conduct medical writing, publications, or PowerPoint lectures, this can lead to embarrassing spelling errors that are not captured by the spell check.

Spell checking drug names like atorvastatin (Lipitor®) can be frustrating. Avoid spelling errors (and the dreaded red squiggly lines) with the ClinCalc DrugSpell dictionary file. It’s free!

Calculate a “Fragility Index” to see which clinical trials BARELY meet statistical significance

ClinCalc.com's Fragility Index Calculator

When evaluating a clinical trial, readers often jump to the P value of the primary endpoint to determine whether the results of a trial are “statistically significant” or not. Although the P value is truly a continuous variable, the scientific community has been conditioned to disregard all results with P values ≥ 0.05, but to fully endorse any trials with a “statistically significant” P value less than 0.05.

Putting the debate and controversy about P values aside for the moment, as a reader, would you be less impressed with a study that changed from being statistically significant to insignificant if one single patient changed from not having the primary endpoint to having the primary endpoint? Especially in an era with a blind reliance on P values, the knowledge of the “fragility” or “robustness” of a study’s P value is another useful data point for readers to critically understand and analyze the results of a clinical trial.

The Concept of the “Fragility Index” for Clinical Trials

New Colistin (colistimethate sodium) Calculator

Pseudomonas aeruginosa nutrient agar

Colistin (in the form of colistimethate sodium, or CMS, in the United States) is an older, last-line agent for multidrug-resistant gram-negative infections.  Because of colistin’s complex pharmacokinetics and for historical reasons, there is a paucity of data regarding its dosing in patients with severe gram negative infections, particularly for those with concurrent renal dysfunction.

In one of the largest pharmacokinetic analyses of colistin to date, Garonzik et al. published a detailed analysis of CMS dosing in critically ill patients.  This analysis included dosing recommendations for patients with normal renal function, acutely changing renal function, intermittent hemodialysis (IHD), and continuous renal replacement therapy (CRRT).

ClinCalc is excited to announce our new colistin dosing calculator, which is based on the Garonzik pharmacokinetic recommendations.  This calculator was developed in coordination with Julie Ann Justo, PharmD, MS, BCPS, AAHIVP — an Assistant Professor at the South Carolina College of Pharmacy who specializes in infectious diseases and HIV pharmacotherapy.
