Full Prescribing Info
Pharmacotherapeutic Group: Humulin 70/30. ATC Code: A10A D01.
Humulin 70/30 is an intermediate acting insulin preparation. It is a premixed suspension of rapid and long acting insulin. Its action is prolonged by the inclusion of protamine sulphate in the suspension.
Pharmacology: Pharmacodynamics: The prime activity of insulin is the regulation of glucose metabolism.
In addition insulin has several anabolic and anti-catabolic actions on a variety of different tissues. Within muscle tissue this includes increasing glycogen, fatty acid, glycerol and protein synthesis and amino acid uptake, while decreasing glycogenolysis, gluconeogenesis, ketogenesis, lipolysis, protein catabolism and amino acid output.
The typical activity profile (glucose utilisation curve) following subcutaneous injection is illustrated below by the heavy line. Variations that a patient may experience in timing and/or intensity of insulin activity are illustrated by the shaded area. Individual variability will depend on factors such as size of dose, site of injection temperature and physical activity of the patient. (See figure.)

Pharmacokinetics: The pharmacokinetics of insulin do not reflect the metabolic action of that hormone. Therefore, it is more appropriate to examine glucose utilisation curves (as discussed previously) when considering the activity of insulin.
Toxicology: Preclinical Safety Data: Humulin is human insulin produced by recombinant technology. No serious events have been reported in subchronic toxicology studies. Human insulin was not mutagenic in a series of in vitro and in vivo genetic toxicity assays.
