I saw a new neurologist Monday, here in Marble Falls. Bottom line, I'm happy with him. Not only is he in town, so no more 2 hour drives each way to Temple, but he has dealt with this for a long time, was knowledgeable on recent developments, did more tests, and is considering more options than my previous neurologist.
By way of example, my previous neurologist didn't have MAO-B inhibitors on her "go to" medications. She said because she didn't feel the benefits to side-effect ratio was good. She pointed to diet restrictions as evidence of a difficulty using them.
MAO inhibitors essentially inhibit the production of an enzyme. MAO-A inhibitors are used in psychotic diseases and have significant diet restrictions to avoid the chemical tyrosine, which can cause hypertensive reactions among other issues when MAO-A is present at the same time. MAO-B inhibitors, however, don't have those restrictions on diet. But when they came out, the FDA automatically gave them the same restrictions as MAO-A inhibitors. Later, as evidence was accumulated that the B version didn't have the same risks as the A one, the FDA relaxed the dietary requirements on MAO-B inhibitors. By inhibiting the MAO-B enzyme, which breaks down dopamine in the body to get rid of older dopamine molecules, it allows the dopamine in your system to hang around longer. That makes any dopamine produced by your brain cells still alive to work longer, as well as any taken in the form of Sinemet--the main drug used in PD.
One MAO-B inhibitor has been around for a while. At one point it was thought to have neuro-protective action, but was not proven to be true in the end. However, 10 years ago a new form came out with the brand name Azilect. It has shown evidence of slowing down the progression of PD. The first med to do so. All others treat symptoms only.
There is your PD lesson for the day. All that to point out that my previous neurologist didn't appear to know about MAO-B inhibitors not having the same diet restrictions as the A version. It was obvious she wasn't going to prescribe any of those. I thought we should at least give them a try and see, but she didn't seem to be open to doing that.
Not so with the new neurologist. He first went through a list of meds and asked me whether I'd taken any of them. The list was longer than I expected, and I could say no to them all because the only ones I'd had was Sinemet and a dopamine agonist. Then he ended that by giving me a history of PD meds, like what I'd read and given above, and ended that he'd like to prescribe Azilect for me. I didn't even have to bring any of it up. And through his presentation he described the diet restriction issue that I've detailed above.
The result being he has been dealing with this since the 60s, knows his stuff, and is open to finding the best med mix among a wide array of options instead of the narrow range of the previous neurologist. And he is not only willing to prescribe a MAO-B inhibitor, he brought it up as the first option to try. So I'm feeling a lot more confident that he can help me.
The down side is that Azilect is still under patent, which expires in Feb. 2017. Until then, there is no generic equivalent. Which means the medication is expensive. Looking on line, a 30 day supply retails just over $600, and with discounts will go anywhere from the upper $400s to the lower $500s. IOW, a month's supply would be more than our car payment.
Upon telling him I didn't have insurance to cover that, he pointed me to the company who has patient assistance programs. After searching, I found the qualifications and form to submit, which based on their info I should qualify for, I can get it for free. So I've filled out the form and sent it to the neurologist, he's filled in his part. I'll pick it up today and fax it into the company with my proof of income. Not sure how fast they'll process it and I'll get it if approved, but I'm hoping I'll have it by the end of next week. We'll see.
Aside from that, he confirmed the previous neurologist's diagnosis that I have PD. He said something along the lines of me fitting the standard characteristics, so for him, there is no doubt that this is PD, and not some other disease that mimics PD symptoms.
So it appears I'll get to try out this med and see how much it helps. I'll keep you updated. I'm going back to see him again in February.
Until I have more info . . . bye.
