Gabapentin-Induced Liver Toxicity. Chahal, Japjot MD 1; Arif, Muhammad Osman MD 2; Achufusi, Ted George MD 1. Author Information . 1 Internal Medicine, SUNY Upstate Rare individual case reports of liver injury from gabapentin have been published, although the causal relationship of gabapentin with the liver injury was not always clear. The latency to onset in these reports was 1 to 8 weeks and associated with cholestatic pattern of enzyme elevations. Gabapentin and Cirrhosis of the Liver - Fatty Liver Disease Gabapentin was held and patient’s liver function tests improved, with ALP 1058 IU/L, AST 158 IU/L, and ALT 149 IU/L, and remained stable. Patient discontinued gabapentin and was advised to follow up outpatient, unfortunately he was lost to follow-up. Herein, we report a gabapentin-induced hepatocellular injury in a patient without another identifiable cause for acute liver injury. Discontinuing gabapentin resulted in rapid reversal improvement in hepatocellular injury. Keywords: gabapentin, hepatotoxicity, drug-induced liver injury. In biological systems, Vitamin E is a major antioxidant that acts as a powerful chain-breaking agent through peroxyl radicals scavenging [58] with increasing the activities of antioxidant enzymes like catalase, SOD, and glutathione-S-transferase in rats [59,60,62,63]. Gabapentin caused elevated liver function enzymes AST, ALT, and ALP beside bilirubin. Gabapentin effects on lipid profile, Blood electrolytes, and functions of kidney and liver of laboratory A drug-induced liver injury is one of the most common causes of acute liver failure. While acetaminophen is the most common etiology, other offending medications include amoxicillin-clavulanic acid, amiodarone, isoniazid, and fluoroquinolones to name a few. Gabapentin, a gamma-aminobutyric acid (GAB Can administration of gabapentin for trigeminal neuralgia dramatically increase liver function tests? Liver enzymes are proteins your liver uses for normal liver functions. When your liver is damaged, these enzymes leak out into your blood and can be measured with blood testing called liver function testing. There are several liver enzymes, but the ones that show liver damage from medications are aspartate transaminase (AST) and alanine Gabapentin, a common over-the-counter pain reliever and fever reducer, has been linked to rare individual case reports of liver injury. The causal relationship between gabapentin and liver damage is unclear, with the latency to onset being 1 to 8 weeks. Gabapentin enacarbil and gabapentin are associated with a low rate of transient serum enzyme elevations during treatment and with rare instances of clinically apparent liver injury. Gabapentin enacarbil (gab" a pen' tin) enacarbil (en" a kar' bil) is a prodrug of and long acting form of gabapentin. Gabapentin affects nerves and chemicals in your body that are involved in some types of pain and in seizures. There is insufficient data to estimate incidence for these or establish whether gabapentin is the sole cause of elevated liver function tests, notes Pfizer. The activity of liver enzymes, with 20 mg/kg of GPN were not significantly different from the control group but, the serum levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, direct bilirubin and total bilirubin were enhanced significantly with 100 mg/kg of GPN. After gabapentin was discontinued, liver enzymes began to downtrend with discharge values of AST 16, ALT 35, ALP 413, Tbili 9.3 and INR 1.1. Vitamin E protects against gabapentin-induced chronic hepatic and renal damage associated with the inhibition of apoptosis and tissue injury in rats. One study found that up to 9% of people without symptoms have elevated liver enzymes on a standard liver screening test. Most often, you won’t have any signs of elevated liver enzymes unless these elevations become severe, and you develop liver damage. In most cases, gabapentin doesn’t hurt the liver or kidneys, though proper dosing is important to prevent side effects. Learn how gabapentin affects the liver and kidneys here.

The activity of liver enzymes, with 20 mg/kg of GPN were not significantly different from the control group but, the serum levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, direct bilirubin and total bilirubin were enhanced significantly with 100 mg/kg of GPN. Magnetic resonance cholangiopancreatography showed no biliary abnormalities. After gabapentin was discontinued, liver enzymes began to downtrend with discharge values of AST 16, ALT 35, ALP 413, Tbili 9.3 and INR 1.1 (Figure). Discussion: Gabapentin induced liver injury is rare with few reported cases, many of which did not exclude other
