Clomipramine is a tricyclic antidepressant used in the therapy of obsessive-compulsive disorder. Clomipramine can cause mild and transient serum enzyme elevations and is rare cause of clinically apparent acute liver injury.
Clomipramine (kloe mip' ra meen) is a dibenzazepine derived tricyclic antidepressant which acts by inhibition of serotonin reuptake within synaptic clefts in the central nervous system, thus increasing brain serotonin levels. Clomipramine also has some blocking activity at postsynaptic dopamine receptors. Clomipramine ...
Liver test abnormalities have been reported to occur in up to 16% of patients being treated with tricyclic antidepressants, but elevations are uncommonly above 3 times the upper limit of normal. Serum aminotransferase elevations during clomipramine therapy are reported in 1% to 3% of patients and the abnormalities were...
The mechanism by which clomipramine causes serum aminotransferase elevation is not known. It undergoes extensive hepatic metabolism and a possible cause of liver injury is production of a toxic intermediate of metabolism that may be directly toxic or may induce a hypersensitivity reaction.
The serum aminotransferase elevations that occur on clomipramine therapy are usually self-limited and do not require dose modification or discontinuation of therapy. The acute liver injury caused by clomipramine is typically self-limited and benign. Results of rechallenge after acute liver injury from clomipramine has ...

Acute liver injury during foscarnet therapy might be a result of a hypersensitivity reaction to the drug or of a complication of the condition for which foscarnet was used.
The serum aminotransferase elevations during foscarnet therapy are usually self-limited and do not require dose adjustment. Foscarnet is usually given to severely immunocompromised patients who are frequently on multiple other medications, many of which may be hepatotoxic and attribution of hepatic injury in such indiv...

Nilutamide
2023-03-15
Nilutamide is a first generation, oral nonsteroidal antiandrogen similar in structure to flutamide that is used in the therapy of prostate cancer. Nilutamide is associated with a low rate of serum aminotransferase elevations during therapy and with rare instances of clinically apparent, acute liver injury.
Nilutamide (nye loo' ta mide) is an anilide nonsteroidal antiandrogen that blocks the binding of endogenous androgens to intracellular androgen receptors blocking their effects. Nilutamide has been shown to be effective in reducing pain and disease progression in metastatic prostate cancer when administered in conjunct...
In large registration clinical trials, ALT elevations occurred in 8% (range 2% to 33%) of patients during nilutamide therapy. The elevations were usually mild, asymptomatic and transient, requiring drug discontinuation in only 1% of treated patients. In rare instances, clinically apparent acute liver injury has occurre...
The mechanism of nilutamide hepatotoxicity is unknown, but toxic metabolites of the agent may induce oxidative stress or interfere with mitochondrial function.
The mild ALT elevations during nilutamide therapy are usually self-limiting even with continuation of the medication. The rare instances of clinically apparent liver injury are usually self-limiting, but several fatal instances have been reported. Monitoring of liver tests is recommended before starting treatment and a...

Tizanidine

Tizanidine is a commonly used muscle relaxant that has been linked to rare instances of acute liver injury, a few of which have been fatal.
Tizanidine (tye zan' i deen) is an imidazoline derivative and is a centrally acting muscle relaxant used for therapy of acute muscle spasms and chronic spasticity. The mechanism by which tizanidine causes skeletal muscle relaxation is not well known; it appears to act at the level of spinal cord pain reflexes, most lik...
Transient and asymptomatic elevations in serum ALT greater than 3 times the upper limit of normal occur in ~5% of patients taking tizanidine compared to 0.4% of subjects on placebo. Reports of severe hepatotoxicity, acute liver failure and death have been mentioned in review articles on tizanidine, but few case reports...
The cause of acute hepatic injury from tizanidine is unknown, but is probably idiosyncratic due to hypersensitivity.
The idiosyncratic liver injury due to tizanidine ranges from hepatitis with jaundice to acute liver failure leading to death. Chronic injury and vanishing bile duct syndrome have not been reported after tizanidine therapy. Recurrence on re-exposure has been reported and rechallenge should be avoided. No cross reactivit...

Folic Acid
2018-02-06
Folic acid is a water soluble vitamin found in many foods and particularly in leafy green vegetables that is essential for the critical biosynthetic pathways involving transfer of methyl groups to organic compounds. There is no evidence that folic acid, in physiologic or even super-physiologic, high doses, causes liver...
Folic acid (fo' lik a' cid) is the critical water soluble vitamin that plays an essential role in many biosynthetic pathways largely as a major donor of one-carbon molecules such as methyl groups. Folic acid is a pteroylglutamic acid, but it exists in several related congeners such as tetrahydrofolic acid (the activate...
Neither normal nor excessively high intakes of folate are associated with liver injury or liver test abnormalities. In long term clinical trials, serum enzyme and bilirubin elevations were no more frequent with folic acid therapy than with placebo. Use of high doses of folic acid (up to 15 mg daily) has not been associ...
It is not clear how folate might cause liver injury. Folate is stored in the liver, but it is metabolized in many tissues and has no effects on the hepatic microsomal enzyme systems.\n\nDrug Class: Vitamins\n\nOther Drugs in the Class: Vitamin A, Vitamin B, Vitamin C, Vitamin D, Vitamin E, Vitamin K, Niacin

Rofecoxib
2020-03-20
Rofecoxib is a nonsteroidal antiinflammatory drug (NSAID) that selectively inhibits cyclooxgenase-2 (Cox-2), which was used in the therapy of chronic arthritis and mild-to-moderate musculoskeletal pain. Rofecoxib was withdrawn in 2004 because of an association with an increase in cardiovascular events with its long ter...
Rofecoxib (roe" fe kox' ib) is a nonsteroidal antiinflammatory drug that acts through selective inhibition of cyclooxgenase-2 resulting in decreased prostaglandin synthesis and thereby decreasing inflammation, fever and pain. The specificity for Cox-2 is believed to make rofecoxib less likely to cause gastrointestinal ...
In clinical studies involving several thousand patients treated for at least 3 months, the rate of serum aminotransferase enzyme elevations above three times the upper limit of the normal range was 1.8% in rofecoxib treated compared to 0.3% in placebo treated patients and 0.1-0.4% in patients receiving other common NSA...
The cause of acute hepatic injury from rofecoxib is unknown. The clinical pattern of injury resembles that of other NSAID induced liver injury.
The idiosyncratic liver injury due to rofecoxib can lead to prolonged jaundice, but has not been associated with acute liver failure or vanishing bile duct syndrome. In the few cases that have been described, the time to recovery has varied greatly, but is usually 1 to 3 months. Rechallenge should be avoided, but there...
