Substances: insulin aspart, insulin aspart protamine
Controlled studies on differences between men and women are lacking. One meta-analysis has shown a possible higher risk of hypoglycemia in women.
No studies with a clinically relevant sex analysis regarding the pharmacokinetics of insulin aspart have been found.
No studies with a clinically relevant sex analysis regarding the effects of insulin aspart have been found.
No study on sex differences regarding safety of insulin aspart has been found. Analyses of other insulins have however shown a higher risk for women to have hypoglycemic events.One study retrospectively analysed four large trials including 713 patients (378 men, 335 women) with type 2 diabetes. Insulin glulisine was added to a basal treatment with oral antidiabetic drugs (OAD) and insulin glargine. Female sex was identified as a predictor of nocturnal and symptomatic hypoglycemia (OR 1.82; 95 % CI 1.07-3.11 and OR 1.89; 95% CI 1.31-2.78) . Furthermore, several meta analyses have shown similar data [2-4].
Concurrent administration of insulin aspart and oral contraceptives may decrease the effect of insulin aspart . Regarding drug-drug interactions aspects, please consult Janusmed Interactions (in Swedish, Janusmed interaktioner).
Insulin aspart can be used in pregnant women. Insulin requirements may change during pregnancy, and quickly return to normal after delivery . Regarding teratogenic aspects, please consult Janusmed Drugs and Birth Defects (in Swedish, Janusmed fosterpåverkan).
Two observational studies from the 1990’s with a total of 418 patients (43 men, 374 women) reported intentional insulin omission among 1/3 of women to control their weight [6,7].
In a retrospective study in 124 women, perimenstrual changes in selfreported glucose concentrations were found in 61%. Use of oral contraceptives did not diminish variability in blood glucosis . In another study based on questionnaires (406 women) 67% of the participants reported changes in blood glucose levels or glycosuria premenstrually and 70% during the menstrual phase. Those with more cravings had larger elevations in blood glucosis levels suggesting that giving in to cravings might cause the changes .
