I thought I would jot down some points for a future patient who is planning to use Afrezza. This is definitely a game changer. I’ll revisit this topic later to make some updates if necessary (for errors and corrections). Don't forget to read & understand the disclaimer in the end of this article.
1. Dosage & Titration:
For Type 2
This is a big deal for patients using insulin. If you think Afrezza requires training, then you wont believe how much training physicians give to patients to train them on dosage. The current users of prandial insulin have dosage and titration reduced to an art form. Any mistake in dosing results in either severe hypos or high blood sugar. The current RAA (like humalog, novolog etc) are also difficult in terms of calculating the correctional dosage. As current RAA stays in the body for long, you’ve correctional dosage stacked on top of earlier dosage. The risk of Hypos in correctional dosage is also of concern. It’s the Yo-Yo that bothers diabetics.
Here comes the best part. In Afrezza dosage and titration are not of great importance. Before you scream that this is a sales pitch, look at the chart below. You can not imagine Eli Lilly or Novo Nordisk attempting to pull this off (giving rapid acting insulin in patients who have not taken meal)
If you are picture challenged, here is what you need to understand about Afrezza. Even If you take Afrezza without a meal, there is a low chance of a hypo. The variations in PPG is very low even with no meal or 200% of normal meal. In a study 46% of patients using injections misinterpreted dosage in instructions. (From rethink insulin website). This issue should go away with Afrezza.
The reason for this low variations in PPG is due to the unique pharmacokinetics of Afrezza.
For Type 1:
Dosage and titration may be as important, but correctional dosages should be easier to compute. Since Afrezza comes in 2 or 3 standard blister packs,
2. Start insulin early:
The earlier you start, the better off you are.
A lot of articles have been written on this. Best place to go is rethinkinsulin.com, which is a website by Sanofi Aventis that wants Type 2’s to go on Basal. The fact is, Type 2’s need Prandial insulin, but it becomes a hard sell. How do you convince patients to take injections 3-5 times a day when they think that the disease hasn’t worsened? Afrezza is the answer.
We would a paradigm shift in the treatment in the next couple of years. The theme will be “Use Afrezza and halt beta cell decline”.
- Before insulin initiation, patients may have spent an average of about 5 years with an A1C >8% and nearly 10 years >7%
- At diagnosis, up to 50% of a patient's β-cell function may have been lost, and may continue to decline by about 5% annually
Feel free to read my old article to learn more about the decline.
3. Side effects
No more hypos, no more injection site reactions, and allergic reactions, including itching and rash. You will get non-productive cough that goes away in 99+% of patients in a few days. You may undergo periodic lung tests. The initial lung function decline (probably around one third of 1%) is non-progressive & reversible. It is possible that 1-5% may quit using Afrezza due to lung issues (like cough, bronchitis etc). As no permanent damage has been observed in trials to date, I believe one one will get discouraged from trying Afrezza.
I think for Type 2, this captures the risks well. What the PR/Posters/Journal articles show is “ANY CHANGES IN LUNG FUCTION ARE STATISTICALLY INSIGNIFICANT”. It is worthwhile to note that we are comparing the effects on lung function for a drug that uses lung for delivery (Afrezza) and other that is injected. Pic is from link
I’ve reviewed some of these in detail in this article.
Lung function is something that will be discussed ad nauseam now and later. It is totally strange that it took humans to decades to accept that Smoking causes cancer, decades to know that asbestos causes mesothelioma. I’ve seen old advertisements in Time magazine of DDT which is still used in developing countries. There are so many inhaled products used in the market. But when it comes to inhaled insulin, the prevailing sentiment of medical community and others can be summarized by this picture. Many of them don't want to hear, see or talk about the evidence that Mannkind is presenting. Why prejudge? The lung cancer in Exubera patients was less than the percentage in general population.

What is needed is a scientific approach and I hope FDA adheres to that.
4 . Tighter control of blood sugar, less bg testing
You should expect way less variations in bg level, so frequent testing of blood sugar level is not necessary. So way less finger pricks.
5 . When to start on Afrezza
We’ll see rewriting of old rules. Once Lifestyle change + Metformin doesn’t give desired results, you’ll start taking Metformin + Afrezza.
6. Other benefits
a) No more needle phobias
b) No pain and yes gain
c) Zero injection site variability
d) Make pancreas last longer
e) Normal A1C’s
f) Low glycemic variability; read Dr. Hirsch article
g) Little or no finger pricks for bg checks
h) Adhere to ADA guidelines

i) Show off your brand new inhaler toy; And ladies, pick the inhaler that matches with your bag. Rappers can personalize & add bling with some diamond studding's.
j) Take insulin discreetly where you want it & when you want it.
7. Other facts
a) Afrezza is only for meal time insulin
b) Afrezza doesn’t cure diabetes
c) Afrezza can cause light hypos; (read the experiences of some participants; link)

The product is not yet approved by FDA (PDUFA date is Dec 29 2010). FDA will come up with all the instructions once it is approved. Once approved, you should go to fda.gov and search for Afrezza to get the necessary information. For more details, go to official Mannkind website www.mannkindcorp.com
