Active advisories Current and resolved drug shortages lists Coverage for spironolactone shortage drugs Coverage for compounded drugs If no alternatives are available What is a drug shortage? Current Drug Shortages List.

September 19, There is currently a shortage of spironolactone Aldactone in Canada. I have spoken with representatives from Pfizer Canada and USA this morning again and the following are updates. There is a shortage of both 25 mg and mg supplies Canada due to a backorder. The pills are not being discontinued according to the company. These are currently being preferentially released to hospitals as the drugs are used at low doses in heart failure and other medical issues.

Federal government websites often end in. The site is secure. Drug shortages are a global and complex issue having negative impacts on patients, pharmacists, and the broader health care system. Using sales data from 22 Canadian pharmacies and historical drug shortage data, we built machine learning models predicting shortages for the majority of the drugs in the most-dispensed interchangeable groups in Canada. The models consider many variables, including the average days of a drug supply per patient, the total days of a drug supply, previous shortages, and the hierarchy of drugs within different drug groups and therapeutic classes. Once in production, the models will allow pharmacists to optimize their orders and inventories, and ultimately reduce the impact of drug shortages on their patients and operations. Drug shortages are a complex, global problem [ 1 , 2 ] with negative impacts on patients, pharmacists, and the entire health care system. Drug shortages can arise for many reasons, from delays in drug approval to issues with manufacturing, raw material supply, drug distribution, or front-line delivery by pharmacies [ 3 , 4 ]. Unexpected high demands or demand fluctuations can also lead to drug shortages [ 1 ]. For patients, drug shortages can have major implications, for instance when drugs against severe allergies [ 5 ], severe pain [ 6 , 7 ], mental illnesses [ 8 ], childhood diseases [ 9 ], or COVID [ 10 ] become unavailable.

Gastroenterology Gastroenterology Gastroenterology Gastroenterology Gastroenterology Gastroenterology Gastroenterology. Drug manufacturers and suppliers face a similar prediction problem.

We evaluated how well patients taking spironolactone were monitored for hyperkalemia, as well as the association between spironolactone and hyperkalemia. Only two thirds of patients received testing for serum potassium and creatinine levels, and higher baseline serum creatinine levels predicted a high risk of hyperkalemia. These results indicate that appropriate patient selection and close monitoring are essential, especially for patients with renal impairment. Unfortunately, morbidity and mortality rates associated with hyperkalemia have risen to levels higher than those seen prior to RALES. Therefore, we studied criteria for the selection of patients for spironolactone therapy and how well patients taking spironolactone are monitored for hyperkalemia. We examined the outpatient and inpatient electronic files of CHF patients who were prescribed spironolactone between September 2, , and April 1, Information on baseline serum potassium and creatinine concentrations, concurrent medications, demographic information, and ejection fractions was obtained.

When spironolactone was originally developed, scientific studies were investigating epithelial ion transport; understanding ion transport was in its formative stages. The path to the eventual arrival of spironolactone on the US market was a complicated one, with its release finally occurring at a time when Donald Rumsfeld, the current Secretary of Defense, was chief executive officer of G. Spironolactone use in the s and s was fairly widespread for the treatment of hypertension, primary aldosteronism, and edematous conditions; i. What had we learned from the initial treatment experience with spironolactone? The onset of action for spironolactone was found to be characteristically slow, with a peak response at times of 48 hours or more after the first dose.

There is a shortage of both 25 mg and mg supplies Canada due to a backorder. The pills are not being discontinued according to the company. These are currently being preferentially released to hospitals as the drugs are used at low doses in heart failure and other medical issues. By the end of October , the 25 mg pills should be available for shipment to pharmacies in Canada. By early November, the mg pills should again be available as well.

Using sales data from 22 Canadian pharmacies and historical drug shortage data reported to Health Canada, we showed that machine learning models can help pharmacies to predict shortages for a majority of the drugs in the most dispensed IGs. Note that the forecasts overlap the actuals in many instances, but differ at times see IG in the top row for example. Pain Pain Pain Pain Pain. Note also that the shortage impact score is an aggregated outcome variable applying to the entire set of pharmacies, for a specific IG over time. Note that the shortage impact score in blue increases slightly in early denoting a shortage in some pack sizes , rises to a complete shortage in , before dropping again to a partial shortage that is resolved in early For example, Fig. Conclusion Mineralocorticoid receptor antagonists reduce cardiac remodeling and thereby aid cardiac function and decrease mortality. Based on decision trees, XGBoost can also handle both numerical and categorical data and is robust against co-linearity [ 38 , 39 ]. The blue points are the forecasted shortage impact scores for the holdout set. They do have access to a broader set of supply-side data e. Transcatheter occlusion of the left atrial appendage to prevent stroke in atrial fibrillation. Obesity and cardiovascular risk in hypertensive patients with left ventricular hypertrophy.

Multiple pharmacists making the same interpretation could, hypothetically, place several orders and increase demand enough to create a drug shortage that would not have occurred otherwise. In Canada, such protocols were initially released in and updated in by Health Canada [ 16 ] to coincide with the launch of Drug Shortages Canada [ 17 ], a publicly accessible and centralized database for reporting drug shortages and discontinuations. For the purpose of this work, only actual and resolved shortages are relevant anticipated and avoided shortages were removed from the dataset prior to modelling. Conclusion Drug shortages and related supply chain issues can have significant negative impacts on patients, pharmacists, and the broader health care system. Hepatology Hepatology Hepatology. When follow-up laboratory tests within 3 months of starting spironolactone treatment were missing, the records were examined for an explanation. Several measures of interest for IG Angiotensin II Receptor Telmisartan — days of supply, days of supply per patient, and the computed shortage impact score for the IG. Pain Med. Table 1 lists the main predictor variables, as well as any new features engineered from the data. The outcome variable is the shortage impact score described in Section 4. Assessing the predictive capability of ensemble tree methods for landslide susceptibility mapping using XGBoost, gradient boosting machine, and random forest. When a shortage ends, the information is removed from the Current Drug Shortage List and the alternative product s returns to its former benefit status. Peak serum creatinine and potassium levels within 3 months of initiating spironolactone treatment were identified. We summarize the MAE over the entire holdout period to get an average accuracy metric.
