I’m a little bummed about my Minnesota Twins. Drug problems are everywhere and my team is not exempt. Apparently, hydrochlorothiazide is a drug of abuse in MLB’s drug testing policy. Mike Pineda, one of the Twins pitchers failed a drug test and was found to have hydrochlorothiazide in his system.
In clinical practice, for medical purposes, diuretics (loops, thiazides, and potassium-sparing) are used ALL THE TIME. Heart failure, hypertension, and edema are a few of the most common reasons that this general class of medication is used. But why was he taking hydrochlorothiazide? It was reported that he used it to help control his weight. I’m not sure if he had something in his contract about his weight or if he felt that it was affecting his performance. He apparently had enough evidence to convince the judge that he was using it for weight and not masking other performance-enhancing drugs.
I was well aware of hydrochlorothiazide and other diuretics as potential drugs of abuse in individuals looking to cut weight for their particular weight division. Wrestling was a sport in high school that I recall hearing about the potential for drug problems.
Diuretics have been used to help dilute the urine. This can help reduce concentrations of other performance-enhancing drugs (and their metabolites) in the urine. When an individual takes a urine drug screen the hope is that the urine will be diluted enough to not trigger a positive result for another drug. Here’s an article that does a nice job of providing a lot of detail on the illicit practices of diuretic use.
I’m left with a few questions that I can’t seem to find the answer to in this situation. Full disclosure, I am not a lab expert, which maybe you can tell.
- What is a little perplexing to me is why a blood test can’t be drawn for patients who test positive for a diuretic? I can’t imagine the diuretic having any performance benefit at all. The diuretic should not have an impact on blood concentrations of any other performance-enhancing drug. In this case, maybe that was his compelling evidence to get his suspension reduced from 80 to 60 games?
- For sports that do not require a weight cutoff to be met, why are they considered drugs of abuse if blood testing could identify use of performance-enhancing drugs?
- I’m guessing that the dilute urine/diuretic practice has some effect from anecdotal reports, but it would be nice to see someone study this as I can find no studies that report whether this is an effective practice or not to mask other drugs of abuse.
He made a bad decision, trusting his acquaintance. With so much at stake, it is hard to imagine a situation where you’d rely on someone who is not an expert. If anyone from the MN Twins or MLB wants some pharmacy help or education about drugs of abuse, you can contact me here 🙂
