The liver is an important organ of the body with many functions (detoxification, regulation of blood fats, blood sugar...) However, some drugs cause liver damage, making the liver unable to perform its duties. above service.
Drug-induced liver damage is a liver condition that is affected by modern drugs, drugs derived from plants or functional foods. Effects on the liver are determined through liver function tests or clinical signs of impaired liver function.
Drug-induced liver damage, although very rare, is potentially fatal. Based on the values of ALT and ALP tests, this condition can be classified into 3 different types, namely:
Hepatocellular damage; Bile injury; Mixed liver damage Mechanisms of drug-induced liver injury include:
Due to an idiosyncratic reaction: Due to an overreaction of the body to a drug, it may occur in one person but not in another. Mechanism of liver damage is not due to dose, time of drug use. Hepatitis due to this drug is not known in advance. Due to overdose: When used in high doses, for a long time or when used together with some other drugs, it will cause drug interactions because these drugs affect the liver's metabolic and detoxification functions, causing liver damage.
Most drugs after taking, injecting, sucking, applying on the skin, putting the anus can cause liver toxicity to different degrees. Depending on the drug, it can cause hepatitis and acute liver failure or chronic hepatitis, fatty liver, biliary tract disease, because the drug enters the bloodstream and passes through the liver before being excreted in the urine or biliary tract. down the intestines. Especially those who already have chronic liver and biliary diseases, the liver is more susceptible to drug poisoning.

Most patients with liver injury due to drugs have very poor clinical manifestations. Some cases have signs such as:
Unusual color of stools and urine: Urine color becomes darker than usual, dark yellow; Blood spots appear in stool. Bad breath: Due to impaired liver function, some toxins and waste products are excreted through the respiratory tract, causing bad breath. Bitter mouth: When the liver is acutely inflamed causing cholestasis, the patient has a bitter feeling in the mouth Headache, dizziness, constipation, red-yellow urine: These signs can warn of drug-induced liver toxicity . Urticaria, rash: When the liver is weak, the liver's ability to detoxify is poor, causing toxins that have been accumulated in the body for a long time to spread through the skin and cause symptoms of urticaria, itching, rash, Acne. Fatigue, anorexia: Decreased liver function reduces the ability to metabolize and secrete bile, causing digestive disorders, so it is easy to become constipated. However, there are also many patients who are completely normal, only discovered incidentally when doing blood tests and showing elevated liver enzymes.
3. Drugs that cause liver damage
Drug-induced liver damage is a fairly common problem today, accounting for up to 10% of drug-induced side effects. Most drugs are metabolised in the liver and excreted in the bile or urine. Therefore, if the liver is impaired, the function of metabolism, detoxification and excretion of drugs is also affected. Long-term accumulation of drugs that are not metabolized and detoxified causes drug toxicity and liver damage. Some drugs cause liver toxicity such as:
Pain relievers, antipyretic Acetaminophen; Omeprzole gastric ulcer treatment: Causes hepatitis. Drugs that promote muscle growth Anabolic steroids, sex hormones Estrogens and androgens, oral contraceptives: Causes liver tumors. Chlorpromozine (Thorazine): Pseudo-primary biliary cirrhosis. Cimetidine (Tagamet) for the treatment of stomach ulcers, blood diseases Coumadin: Causes acute hepatitis and biliary tract disease. Ciprofloxacin antibiotic: Biliary hepatitis. Antibiotics Clindamycin (Cleocin), Metronidazole (Flagyl); the psychotropic drug Cocaine; Ibuprofen pain relief; Phenytoin antispasmodic; Treatment of breast cancer Tamoxifen: Causes acute hepatitis. Anti-inflammatory drugs Corticosteroids (Prednisone), antibiotics Tetracycline: Causes fatty liver. Erythromycin estolate and the immunosuppressant Cyclosporine A: Causes biliary tract disease. Diazepam (Valium): Acute hepatitis and biliary tract disease. Halothan anesthetic, analgesic Salicylates (Aspirin): Acute and chronic hepatitis. High blood pressure drug Methyldopa (Aldomet): Causes autoimmune hepatitis. The diabetes drug Rosiglitazone (Avandia): Causes liver failure. Anti-tuberculosis drugs such as isoniazid, rifampicin, streptomycin, isoniazid (INH): Causes liver toxicity. Southern and Northern drugs: Poisoning with Southern and Northern drugs causes severe liver damage, even acute liver failure, which can lead to death. Dewormer: Causes hepatitis when used in high doses, for a long time.
