Over-the-counter (OTC) drugs are medicines sold directly to a consumer without a requirement for a prescription from a healthcare professional, [1] as opposed to prescription drugs, which may be supplied only to consumers possessing a valid prescription.
Lente insulin (from Italian lento, "slow"; also called insulin zinc suspension) was an intermediate duration insulin that is no longer used in humans. [1] The onset of lente insulin is one to two hours after the dose is administered, and the peak effect is approximately 8 to 12 hours after administration, with some effects lasting over 24 hours.
Zinc combinations of insulin are used for slow release of basal insulin. Basal insulin support is required throughout the day representing about 50% of daily insulin requirement, [18] the insulin amount needed at mealtime makes up for the remaining 50%. Non hexameric insulins (monomeric insulins) were developed to be faster acting and to ...
Insulin glargine, for example, is designed to precipitate after injection so it can be slowly absorbed by the body over a longer period than regular insulin would be. [13] Depot injections of insulins have been studied to better replicate the body's natural basal rate of insulin production, and which can be activated by light to control the ...
Insulin was first used as a medication in Canada by Charles Best and Frederick Banting in 1922. [85] [86] This is a chronology of key milestones in the history of the medical use of insulin. For more details on the discovery, extraction, purification, clinical use, and synthesis of insulin, see Insulin
Insulin lispro, sold under the brand name Humalog among others, is a modified type of medical insulin used to treat type 1 and type 2 diabetes. [5] It is delivered subcutaneously either by injection or from an insulin pump. [5] [6] Onset of effects typically occurs within 30 minutes and lasts about 5 hours. [5]
Insulin glargine sold under the brand name Lantus among others is a long-acting modified form of medical insulin, used in the management of type 1 and type 2 diabetes. [7] It is injected just under the skin. [7] Effects generally begin an hour after use. [7]
The insulin aspart protamine portion is a crystalline form of insulin aspart, which delays the action of the insulin, giving it a prolonged absorption profile after injection. [14] The combination of the fast-acting form and the long-acting form allows the patient to receive fewer injections over the course of the day. [27]
