NSAID

Specially affected active substances and pharmaceuticals

Name of active substance Trade name Affected micronutrients
Acetylsalicylic acid Aspirin®, Thrombo ASS® Vitamin C
Acetaminophen Mexalen®, ben-u-ron® Nicotinamide
N-acetylcysteine

 

Mechanism of interaction

Mechanism of interaction
Vitamin C The sodium-dependent transport of vitamin C through the intestinal wall is inhibited by salicylates. This results in an increased excretion of vitamin C in urine and feces. This results in a decrease of vitamin C levels in tissue, gastric juice and plasma. At the same time a concomitant administration of vitamin C and ASA shows a protective effect on the gastric mucosa.
Folic acid/
Vitamin B12
Gastrointestinal damage interferes with bioavailability and absorption. Acetylsalicylic acid increases the excretion of folic acid.
Iron Impairment of iron absorption with long-term use. The reason for this is occult gastrointestinal bleeding when taken chronically.
Nicotinamide Nicotinamide is present in the body as NAD. Damage to liver cells caused by paracetamol increases NAD consumption.
N-acetylcysteine N-acetylcysteine stimulates glutathione biosynthesis. This results in hepatocellular detoxification of paracetamol.
Vitamin E Vitamin E regulates the arachidonate metabolism. Taking NSAID at the same time has an additive effect.
Potassium The impairment of renal function when taking NSAID may cause an increase in serum potassium levels. This can lead to hyperkalemia.
Chondroprotective drugs D-Glucosamine is the basic building material of cartilage. Anabolic processes in the cartilage are stimulated and catabolic processes are reduced. They have a synergistic effect with NSAID.
Glutamine L-glutamine is the main energy substrate of the cells of the gastrointestinal tract. It is used to maintain normal intestinal function. L-glutamine protects the gastrointestinal mucosa.
Omega-3 fatty acids Act synergistically. EPA inhibits the formation of proinflammatory enzymes.

 

Consequences and possible symptoms of the interaction

Negative consequences of the interaction Possible symptoms
