So, so, the shortage is with nitroglycerin pills. So the short acting pills and the short acting spray so, you know, in general folks with angina we'll use those skills or sprays I'll just use the word nitro which are changeably. But in general, most will use those to combat episodes of angina. So discomfort with exertion for example, everybody's joining us just a little bit. A common example of it would be getting chest discomfort with exertion. So say climbing a couple of stairs or something like that. Patients will use short activators to combat those episodes. And of course, tracking other situations it's used to the emergency department invasion investigations going on Gnostic casting and that sort of thing, but in my particular sort of thinking, Mr. Smith, who has cardiac disease, who sort of the approach want me to take sure we go, okay. So so the, the Nitro has a has a has a role in treating cardiac disease when patients have symptoms of angina, but really, the foundation the foundation of treating cardiac disease is good medical therapy. So good medical therapy includes like prevention, things like aspirin, cholesterol lowering drug, and in terms of set for symptom relief and for prevention. There's other drugs that are long acting, that helps prevent that from happening in the first place. Right. So you know, we all have lots of patients who are on medical therapy and because they have good medical therapy, so or very rarely, because they have good therapy or on top of medical therapy they've had, they've had stent put in or they've had bypass surgery. They've had they have a foundation of good medical therapy. They have additional therapies like statins for bypass surgery. as needed. And many of them have very good quality of life and have very few symptoms. On the occasions that folks have symptoms, that's when they sort of use that short acting. So the shortage, certainly caused by some concern, but it's also an opportunity to read it as an opportunity to revisit how we're treating our patients. Making sure that folks who are having have a lot of need for nitro are getting have that good foundation in place like is there room to move on some of their long acting drugs? Can we increase doses of other drugs to help prevent the emphasis on so that didn't get used as much as the other authors also, there's also options in the manual, because there are long and military preparations that are not short. So things like natural patches and there's prolonged backing pills that we can also use to help mitigate the challenges that are that you could potentially foresee with a shortage. Right.
