Basaglar vs Lantus – Differences Between Them?

Diabetes patients also need insulin to regulate their blood sugar levels. However, considering there are several insulins that are similar in nature, choosing which insulin can be difficult. So, we’ll talk about Lantus vs. Basaglar in this article to help you better understand the differences and similarities.

Before we dig deep into all the details; Insulin glargine is used for the treatment of patients with type 1 and type 2 diabetes, and Lantus and Basaglar are types of this Insulin glargine. They are very similar to long-acting insulins but are not interchangeable.


What is Insulin Glargine?

Insulin glargine is a long-acting, man-made insulin. Type 1 diabetes patients can use insulin glargine together with quick-acting insulin. Type 2 diabetes patients may use insulin glargine on their own or together with any other insulin to treat their condition.

Insulin glargine is injected under the skin, every day at the same time. It should not be injected if you are showing symptoms of low blood sugar. This drug will either come in insulin pens or vials.

You should not combine insulin glargine with another insulin or substitute this form of insulin with some other type of insulin without talking to your doctor. Also, this form of insulin should never be used in the insulin pump.

Basaglar Insulin

Basaglar is a prescription drug used to boost blood sugar levels in adults and children (6 years and older) with type 1 diabetes and adults with type 2 diabetes. Basaglar contains insulin glargine and is a long-acting insulin type. Basaglar comes in a liquid form and is given as an injection under your skin.

The medication comes in two forms; the Basaglar KwikPen, which holds 3 milliliters (ml of solution), and the Basaglar Tempo Pen, which is a pen that can be connected to a mobile app to record your insulin dose. Tempo Pens also holds 3 ml of solution. Each ml of Basaglar solution consists of 100 units of insulin glargine.


Lantus Insulin

Lantus is also a prescription drug used to improve blood sugar levels in adults and children (6 years and older) with type 1 diabetes and adults with type 2 diabetes. Lantus contains insulin glargine and is a long-acting form of insulin. Lantus is also given as an injection under your skin.  The medication comes as a solution inside a 10 milliliter (ml) vial containing 100 units of insulin glargine per ml. Needles are used with the vial which is not part of the vial.

Lantus comes as a pre-filled SoloStar pen, too.  Each pen consists of 3 ml of drug solution with 100 units of insulin per ml of solution.

Similarities and Differences Between Lantus and Basaglar

Similarities and differences

Basaglar and Lantus are remarkably similar because they contain insulin glargine; they also have the same amino acid chain sequence. They are not only adopted in the same way but are also equal in terms of protection and efficacy.

Basaglar is referred to as a follow-up drug to Lantus. This indicates that it is very similar to Lantus, which is a biological drug. Biologic medications are made from living cells in a laboratory. Follow-up medications are somewhat similar to the original biologic drug. Even though Basaglar is a follow-up to Lantus, it’s not a generic medication. Generic medications contain correct copies of the active ingredient of the brand name drug.

The differences between these two medications are relatively small. First of all, various companies develop these medications and distribute them in different ways. Although they are relatively similar in price, Basaglar is currently a slightly cheaper choice in the United States. These price adjustments can, however, be on the basis of insurance. Lastly, Basaglar is only available as a pre-filled 3 ml pen (100 units/mL (U-100) injection) while Lantus is available as both a 10 ml multi-dose vial and a 3 ml single-patient pen (both 100 units/mL (U-100) injection).

There is no clear response when it comes to deciding which one is better between Lantus and Basaglar. Since Basaglar is a biosimilar, it provides individuals with the same effect as Lantus. More precisely, the best choice for you can depend on which one your insurance cover more.

The Food and Drug Administration (FDA) finds that follow-on insulin is as safe and successful as the initial drug. This means that Basaglar increases blood sugar levels just as Lantus does. It also means that Basaglar and Lantus have similar side effects.
