People with diabetes should use what kind of dosage form of insulin?
The impression of many diabetic patients, if short-acting insulin effect is not good, we must switch to the medium or long-acting insulin, in fact, this argument is wrong. Different formulations of insulin treatment onset time, duration of efficacy, and usage can not be replaced.
Slow, long-acting insulin onset but relatively long duration of efficacy, it simply is able to control blood sugar for a long time, short-acting insulin from the onset time is faster, but very short duration of efficacy, it can only a short period of time blood glucose control, duration of onset and efficacy of insulin in between. Therefore, every person with diabetes should be selected according to the condition of different formulations of insulin.
From the clinical point of view, never used insulin in patients with diabetes early, you must first choice for short-acting insulin, postprandial hyperglycemia and diabetic patients in the acute phase of infection should be used short-acting insulin, and good results. Short-acting insulin (also known as regular insulin) should be 30 minutes before a meal subcutaneous injection of the past two years, listed acting insulin effect quickly, before a meal within 15 minutes of injection can be, if these two insulin injection prematurely will cause low glycemic response.
In general, if during the day have been taking hypoglycemic agents, for further control of blood glucose, bedtime injectable insulin. Meanwhile, in order to reduce the number of insulin in insulin and short-acting insulin used in conjunction. The long-acting insulin alone the effect of poor, often used in combination with short-acting insulin in order to reduce the number of injections.
