(regular insulin human) Injection, USP
(rDNA Origin) 100 Units per ML (U-100)
Humulin® R U-100 is a polypeptide hormone structurally identical to human insulin synthesized through rDNA technology in a special non-disease-producing laboratory strain of Escherichia coli bacteria. Humulin R (insulin human recombinant) U-100 has the empirical formula C257H383N65O77S6 and a molecular weight of 5808.
Humulin R (insulin human recombinant) U-100 is a sterile, clear, aqueous, and colorless solution that contains human insulin (rDNA origin) 100 units/mL, glycerin 16 mg/mL and metacresol 2.5 mg/mL, endogenous zinc (approximately 0.015 mg/100 units) and water for injection. The pH is 7.0 to 7.8. Sodiumhydroxide and/or hydrochloric acid may be added during manufacture to adjust the pH.
Adequate insulin dosage permits patients with diabetes to effectively utilize carbohydrates, proteins and fats. Regardless of dose strength, insulin enables carbohydrate metabolism to occur and thus to prevent the production of ketone bodies by the liver. Some patients develop severe insulin resistance such that daily doses of several hundred units of insulin or more are required.
