Coca and Lixisenatide

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIDIABETES DRUGS

Why this applies to Lixisenatide

Lixisenatide falls under ANTIDIABETES DRUGS — the group Coca interacts with.

Theoretically, coca might reduce the effects of antidiabetes drugs.
Some clinical research suggests that coca and the coca constituent cocaine have hyperglycemic effects. Theoretically, concomitant use of coca with antidiabetes drugs might interfere with glucose control and decrease the effectiveness of antidiabetes drugs.
Severity Moderate Likelihood Possible Evidence B

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the concern with combining coca and lixisenatide (Adlyxin). Lixisenatide is an injectable you use along with diet and exercise to bring your blood sugar down in type 2 diabetes. It is not a prodrug, so this isn't about how your body activates it. The worry is more direct: coca and its main alkaloid, cocaine, can actually raise blood sugar. So in theory, using coca could push your sugar up and work against what lixisenatide is trying to do, making it less effective.

Keep in mind this is mostly theoretical, based on limited research, so it's not a sure thing. Still, if your sugars are running higher than usual, that's worth noticing. Please don't start, stop, or change anything on your own. Talk it over with your pharmacist or doctor first.

From our pharmacist’s overview on the Lixisenatide page

“Lixisenatide (Adlyxin) is injected to lower blood sugar in type 2 diabetes, and nearly everything on this page acts on blood sugar too, which is why I would treat the list with genuine care rather than a shrug. Most of the entries, from bitter melon and fenugreek to both types of ginseng, can push glucose lower still and raise the odds…”

About Coca

What is Coca?

Coca
  • Altitude sickness
  • Fatigue and low energy
  • Appetite and hunger suppression
  • Digestive upset
  • Flavoring agent in foods and drinks

Coca is a South American plant best known as the natural source of cocaine. While the leaves have a long history of traditional use for altitude sickness, fatigue, and hunger, the whole plant contains cocaine and other alkaloids that make it legally controlled and potentially dangerous in most countries. Only decocainized (cocaine-free) coca extract is used in foods, and there is little reliable evidence to recommend coca as a supplement.

About Lixisenatide Injection

What Is Lixisenatide Injection Used For?

Brand name: Adlyxin

  • Lixisenatide injection is used along with diet and exercise to treat type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood). Lixisenatide injection is not used to treat type 1 diabetes (condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood). Lixisenatide is not used instead of insulin to treat people with diabetes who need insulin. Lixisenatide injection is in a class of medications called incretin mimetics. It works by stimulating the pancreas to secrete insulin when blood sugar levels are high. Insulin helps move sugar from the blood into other body tissues where it is used for energy. Lixisenatide injection also slows the emptying of the stomach and causes a decrease in appetite.

  • Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Using medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.

  • Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with lixisenatide injection and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) to obtain the Medication Guide.
