We study 323,232 people who take Gabapentin (gabapentin) or have Elevated liver enzymes. No report of Elevated liver enzymes is found in people who take Gabapentin. The phase IV clinical study is created by eHealthMe based on reports from the FDA, and is updated regularly. Clinical findings showed that gabapentin led to significant elevation of liver enzymes (ALT, AST, and GGT) and bilirubin levels while other causes of viral hepatitis were excluded (7). At therapeutic dose GPN is a safer drug with regards to liver function and hepatocellular damage as compared with other antiepileptic drugs. Gabapentin (GPN) is a new antiepileptic agent currently in used as add-on therapy in adult patients suffering from partial seizures. Gabapentin is an uncommon cause of DILI reported to cause a hepatocellular, cholestatic, or mixed picture of liver injury. Given the limitations of prior cases, we feel our report most closely ties gabapentin use to the resultant transaminase elevation. 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. Different reports suggest that gabapentin has a low profile of interaction with other drugs, 68, 69 hepatic enzymes 68 and plasma proteins. 69 In addition, gabapentin is recommended for special groups such as elderly patients suffering from hepatic diseases, 68 patients with cancer, and others. 70 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 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 More recent research examining liver cells has shown that these liver enzyme elevations are due to cell leakage rather than injury. Experts have termed these liver “adaptations.” They estimate liver injury from statins is closer to 1%. 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 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. Other AEDs with rising and currently highest prescription rates were associated with few or no cases of liver injury including gabapentin (45.3 million), clonazepam (18.8 million), pregabalin (10.6 million), topiramate (9.3 million), and levetiracetam (7.7 million) and many of cases were judged as only “probable”. Elevated liver enzymes are found in 2–4% of the patients with chronic therapy 90 but no significant heptotoxicity has been reported. In the presence of underlying liver disease, considering the long half-life, clinical and biochemical monitoring is advisable. 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 (Neurontin) usually isn’t bad for your liver or kidneys. In most cases, it has little effect on these organs. In rare instances, gabapentin can cause DRESS (drug reaction with eosinophilia and systemic symptoms) syndrome. Gabapentin is not metabolized by the liver. Instead, it is excreted unchanged in your kidneys after circulating in your blood. Gabapentin affects nerves and chemicals in your body that are involved in some types of pain and in seizures. Gabapentin, a water-soluble amino acid, is eliminated unchanged by the kidneys and there is no appreciable metabolism by the liver. However, there are a few descriptions of gabapentin-related 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 is a long acting form of gabapentin that is used for restless leg syndrome and for painful postherpetic neuropathy. 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].
