Final answer:
Premixed insulins like the 70/30 and 50/50 ratios contain combinations of intermediate-acting and short-acting insulins. They provide a convenient option for diabetic patients as they only need to inject once instead of separately injecting two types of insulins.
Step-by-step explanation:
Premixed insulins, such as the 70/30 and 50/50 ratios, are available for diabetic patients. The 70/30 insulin mix consists of 70% NPH (Neutral Protamine Hagedorn) insulin and 30% Regular insulin. NPH insulin is an intermediate-acting insulin that helps control blood sugar levels throughout the day, while Regular insulin is a short-acting insulin that helps control blood sugar levels after meals.
These premixed insulins provide a convenient option for patients who require both intermediate-acting and short-acting insulins. By combining them into a single insulin formulation, patients only need to inject once instead of separately injecting two types of insulins.
