Many insulin analogs and GLP-1 agonists for diabetes treatment are available as injector pens. [2] As with insulin vials, some insulin pens are made with higher concentrations including U-200, U-300, and U-500. Different concentration insulin products may not have the same pharmacokinetic properties as other strengths. [10]
Lente insulin (derived from the Italian word lento, meaning "slow"), also known as insulin zinc suspension, was an intermediate-acting insulin that is no longer used in humans. [113] Its effects begin one to two hours after administration, with peak activity occurring approximately 8 to 12 hours post-injection, and some residual effects lasting ...
In many people, both a rapid- or short-acting insulin product as well as an intermediate- or long-acting product are used to decrease the amount of injections per day. In some, insulin injections may be combined with other injection therapy such as GLP-1 receptor agonists. Cleansing of the injection site and injection technique are required to ...
"Tuberculin" syringes and types of syringes used to inject insulin are commonly used. Commonly used syringes usually have a built-in 28 gauge (or thereabouts) needle typically 1/2 or 5/8 inches long. The preferred injection site is the crook of the elbow (i.e., the Median cubital vein), on the user's non-writing hand
An injection (often and usually referred to as a "shot" in US English, a "jab" in UK English, or a "jag" in Scottish English and Scots) is the act of administering a liquid, especially a drug, into a person's body using a needle (usually a hypodermic needle) and a syringe. [1] An injection is considered a form of parenteral drug administration ...
Subcutaneous administration is the insertion of medications beneath the skin either by injection or infusion. A subcutaneous injection is administered as a bolus into the subcutis, the layer of skin directly below the dermis and epidermis, collectively referred to as the cutis. The instruments are usually a hypodermic needle and a syringe.
There are several types of insulin that are commonly used in medical practice, with varying times of onset and duration of action. [32] - Rapid acting (i.e. insulin lispro) with onset in 15 minutes and duration of about 4 hrs. - Short acting (i.e. regular insulin) with onset in 30 minutes and duration of about 6 hrs.
Basal insulin is provided as a once or twice daily injection of dose of a long-acting insulin. In an MDI regimen, long-acting insulins are preferred for basal use. An older insulin used for this purpose is ultralente, and beef ultralente in particular was considered for decades to be the gold standard of basal insulin.
