Final answer:
Insulin Lispro (Humalog) is classified as Pregnancy Category B by the FDA, indicating no known risk to the fetus. It is a fast-acting insulin engineered for effectiveness, and it is a combination of E. coli and human insulin.
Step-by-step explanation:
The pregnancy category of Insulin Lispro (Humalog) is not Category D or Category E, as the student has suggested, but it has been classified as Pregnancy Category B by the FDA. This means that Insulin Lispro does not show any risk to the fetus in animal reproduction studies and there are no adequate and well-controlled studies in pregnant women, or that animal reproduction studies have shown an adverse effect, but adequate and well-controlled studies in pregnant women have failed to demonstrate a risk to the fetus during the first trimester of pregnancy, and there is no evidence of risk in later trimesters.
Insulin Lispro is a fast-acting insulin that is a combination of E. coli and human insulin. It is engineered to be more effective than human insulin produced in the pancreas. It matches more closely the way insulin is naturally released in the body in response to blood sugar increases after meals, thereby helping to control blood sugar levels more efficiently. It is not identical to the human insulin produced in the pancreas, but it mimics its effects. Contrary to some misconceptions, it is not cheaper and less effective than pig insulin for treating diabetes.
