Default Re: Hello! Rolo and I are new here.

What's available on the internet about Lantus use in dogs is not complimentary. It's a totally different story regarding its use with cats.

Evaluating the array of insulin products for companion animals
DVM 360 magazine September, 7, 2007

Dr. Anthony Abrams-Ogg, at the 2007 American College of Veterinary Internal Medicine Forum in Seattle, lectured on "Chemistry and Pharmacology of Therapeutic Insulin Preparations."

"The use of glargine is increasing in cats as a long-acting substitute for human Ultralente and alternative to beef and beef/pork PZI. Its use results in improved glycemic control when used once or twice daily, but, as with other long-acting insulins in cats, glycemic control is best with twice-daily administration. Pharmacokinetic studies in normal dogs demonstrate erratic absorption. "

COMPARISON OF THE PHARMACODYNAMICS AND PHARMACOKINETICS OF SUBCUTANEOUS GLARGINE, PROTAMINE ZINC, AND LENTE INSULIN PREPARATIONS IN HEALTHY DOGS

ACVIM 2004

VJ Stenner, LM Fleeman, and JS Rand. Centre for Companion Animal Health, School of Veterinary Science, The University of Queensland, Brisbane, Australia.

"The pharmacodynamic and pharmacokinetic effects of glargine, a recombinant human insulin analogue, protamine zinc beef-pork insulin (PZI), and a purified pork lente insulin preparation were evaluated in 9 healthy neutered dogs (4 male, 5 female).

"Serum glucose concentration was significantly decreased in all dogs following the administration of lente and PZI insulin, and in 7 of 9 dogs following glargine administration. Two dogs showed no significant change in serum glucose concentration after glargine administration and were excluded from the analysis of glargine pharmacodynamic data.

"Following glargine administration, there was a trend for peak insulin concentrations to occur between 0.5 and 6hr. The serum insulin concentrations did not exceed the critical difference in 3 dogs following glargine and in 2 of these dogs, there was no significant glucose-lowering effect.

"We conclude that in healthy dogs:

"3) Glargine administration results in an unpredictable serum insulin concentration response and, in some dogs, fails to produce a significant glucose-lowering effect."

Drs. Rand and Fleeman are well-known for their many studies involving Lantus and cats, so they can hardly be said to be biased against the insulin.

Selecting an Insulin for Treating Diabetes Mellitus in Dogs and Cats

"In my experience, insulin glargine has a duration of effect ranging from 10 to 16 hours in most diabetic dogs and cats."

"My experience with insulin glargine in diabetic dogs has been mixed and somewhat disappointing."

So we have four specialists here, saying Lantus is not reliable and even disappointing, whether the dog is diabetic or not. It doesn't seem possible that all four of them have an anti-Lantus bias, but that in their considerable experiences, it didn't live up to expectations for the most part.

No insulin, no matter what it is, is panacea in a vial; some will have success with it and others will not.
