Expectorants, Decongestants, and Medent-LD for Asthma

Andrew:
Let’s take one last question for our asthma segment with Peggy in Randalstown, Maryland. Peggy, welcome to “HealthTalk Live!” What’s your question?
Peggy:
Hello. My mother is 88 years old, and she was recently diagnosed with asthma. Her doctor prescribed two medications that I haven’t been able to find any information on. I’ll spell them for you: Medent-LD and Avelox [an antibiotic].
Dr. Corsello:
I’m not familiar with the second one, but the first one, Medent-LD, is a drug that’s similar to many drugs on the market. It contains a substance called guaifenesin, which is an expectorant. Expectorants are drugs designed to enable you to clear secretions more easily. The other ingredient of Medent is pseudoephedrine, which is known to most people as Sudafed, which is a decongestant. And the combination is designed, I would think, to allow for secretion clearage and to dry up some of the membranes producing those secretions. It’s not conventionally the medication that we use to treat asthma.

Also, at the age of 88, recently diagnosed with asthma, once again I would make the point that there are many medical conditions that can masquerade as asthma but not be asthma. These range from conditions such as a foreign body in the airway, the development of low-grade infection, and a number of other diseases that cause inflammation of the lung with associated wheezing.

So it’s most important that one be assured, as Royce said a few moments ago, that the diagnosis of asthma is correct, especially when some of the features of the condition that’s being called asthma don’t fit and especially when it occurs in a circumstance that is most unusual – the onset of asthma in the ninth decade.

Andrew:
So once again, don’t be shy. Ask questions. And as Royce said earlier in the program, the least expensive approach of all, as he said, is a second opinion.
Dr. Corsello:
I agree with that, and as I mentioned earlier, a number of things are important in your relationship with your physician, but one of them is that it’s a mutually respectful relationship where your physician is willing to listen and take seriously your questions and concerns. If that doesn’t exist in the relationship, then you have less than an ideal relationship and may have to take action to change that.
Andrew:
Good advice. I hope that helps you, Peggy. Best wishes with your mother. We’re going to move on, though, okay?
Peggy:
Okay. Thank you.
Andrew:
Dr. Corsello, the time has flown by. We thank you for your time, too, for joining us from National Jewish Research and Medical Center in Denver, the top center for asthma. We’ve all learned a lot. I bet some doctors have been listening and learning, and people will be quoting you as they go back to their doctors. Maybe you or one of your colleagues can join us again on “HealthTalk Live!” We really appreciate your time.
Dr. Corsello:
I would like that. Thank you very much, Andrew. It’s been a pleasure.
Andrew:
Thank you so much.
