  1. After two separate trials, it was clear that 10mg Lipitor
    (atorvastatin) was having an adverse effect on my glucose
    control, which is typically in the high normal/low impaired
    range since I lost weight. Pravachol (pravastatin) doesn't
    have such an effect on me, but it doesn't lower my
    cholesterol anywhere near as well either. (I haven't had any
    other significant side effects from either drug except some
    very mild and short-lived aching in one thigh.)

    I originally posted about this late last year, starting a
    thread called "Lipitor Clearly Worsening Glucose Control".
    (Web link via Google: groups.google.comgroups
    pitor+clearly+worsening+glucose+control+group:misc.health.-
    diabetes )

    Since starting that original thread, I found the following
    rodent study abstract on Medline. Granted, it was a small
    exploratory study on animals, but the results parallel mine
    so very closely, namely:
    (1) "Subjects" started with "borderline" glucose
    intolerance, (2) Lipitor increased post-meal glucose
    sometimes while Pravachol didn't,
    (2) This effect took a few weeks to emerge, and (4)
    (Presumably), neither statin affected fasting glucose.

    I wish someone would do a really GOOD, human study on this,
    but who would fund it? Maybe in pre-diabetic or (thus far)
    mildly diabetic people, even a minor deterioration in
    glucose tolerance from Lipitor could outweigh the drug's
    protective benefits.

    I've set off the key conclusions below with asterisks.

    Effects of atorvastatin [Lipitor] and pravastatin
    [Pravachol] on glucose tolerance in diabetic rats mildly
    induced by streptozotocin.

    Kanda M, Satoh K, Ichihara K.

    Department of Pharmacology, Hokkaido College of Pharmacy,
    Katsuraoka, Otaru, Japan.

    Effects of atorvastatin [Lipitor] and pravastatin
    [Pravachol] on glucose tolerance in mildly induced diabetic
    rats by streptozotocin at 24 mg/kg, i.v. were studied. Non-
    diabetic and diabetic rats were given orally 0.5%
    carboxymethylcellulose (control), 8 mg/kg atorvastatin or 8
    mg/kg pravastatin once a day for 6 weeks. An oral glucose
    tolerance test (OGTT) was carried out 1, 2, 3, and 6 weeks
    after the administration. The blood glucose and plasma
    insulin levels measured before OGTT in the diabetic rats
    were not different from those in the non-diabetic rats.
    However, the hyperglycemic response to OGTT in the diabetic
    rats significantly exceeded that in the non-diabetic rats.
    The plasma insulin increased by OGTT in the diabetic rats
    appeared to be lower than that in the non-diabetic rats.
    Statin treatments for 1 week did not modify the OGTT-induced
    hyperglycemia appreciably, although there were some
    significant differences. *******More than 2 weeks after
    administration, the blood glucose levels at several time
    points after a glucose intake in the atorvastatin-treated
    diabetic rats were significantly higher than the respective
    levels in the control diabetic rats. Neither atorvastatin
    nor pravastatin modified the OGTT-induced insulin secretion.
    Statins, especially atorvastatin, may influence the glucose
    tolerance in mildly induced diabetic rats without
    alterations of insulin secretion.******

    Way back when I was on D & E + Metformin + Rezulin, I
    started Lipitor and my sugars jumped. Thus, my
    metabolism agrees with your metabolism.

    However, one problem with your desire for studies and risk
    evaluations in this area is that adding insulin to your
    regime totally cancels any bG rise from Lipitor, e.g.. when
    I re-started Lipitor after going on insulin, there was no
    noticeable effect on bG at all, and my lipids improved
    dramatically..

    We have T2 on insulin posting about their 5.2 HbA1c. Thus,
    in the docs' eyes, the problem is "solved".

    Interesting feedback.

    I ordered a copy of the complete study, and the authors say
    that they had also done some prior work which showed *no*
    significant glucose increase from Lipitor, but theorized
    that this might be because the first sudy used rats that had
    a more progressed level of diabetes that "may (have been)
    too severe to detect influence of a drug on the diabetic
    state." Now, I *have* seen summaries of a few studies
    (including human studies) that cite Lipitor's lack of
    significant effect on glycemia in diabetics, but I doubt
    that -- unlike the current rat study -- these observations
    were based on subjects purposely chosen for having currently
    mild diabetes. Thus the effect may not have been apparent.

    As for your own case, given that you were taking three meds
    at the time Lipitor raised your sugars, this suggests that
    the a Lipitor sugar-raising effect might also appear in
    some cases of somewhat-more-progressed diabetes (but still
    not at the insulin stage). For you, did it also take about
    two weeks to start seeing Lipitor's effect on glucose? And
    did it show up mostly in post-meal readings rather than
    fasting? Was your statment about doctor reactions meant to
    imply that you told your doctor about the effect and he/she
    dismissed it?

    Thanks for the contribution.

  5. Sam I heard something of this on another website. It is easy
    to fix just change statins, I use Zocor with no problems.
