| Hepatotoxicity | Serum aminotransferase elevations during hydralazine therapy are considered uncommon. However, hydralazine has been clearly linked to cases of acute liver injury with jaundice as well as a delayed lupus-like syndrome. Two clinical patterns of hepatic injury have been described, associated with either a short (2 to 6 weeks) or long (2 months to more than a year) latency period. The clinically apparent liver injury is usually hepatocellular, although cholestatic forms have also been reported (Case 1). In cases with a short latency period, rash, fever and eosinophilia are common and the onset is typically abrupt and severe, and recovery is rapid. In cases with a longer latency (Case 2), the onset is more typically insidious, liver biopsy may resemble chronic hepatitis and demonstrate fibrosis, and autoantibodies are often present. The late form of hepatitis may also accompany the lupus-like syndrome that occurs with hydralazine, particularly in high doses when given for 6 months or more. Recovery can be prolonged. Autoantibodies to isoforms of the P450 system (CYP 1A2) have been identified in patients with hepatotoxicity due to the structurally related antihypertensive agent dihydralazine (available in Europe, but not the United States) and which is associated with a higher rate of hepatotoxicity than hydralazine. |
| 유해 작용 | Skin Sensitizer - An agent that can induce an allergic reaction in the skin.Hydralazine has been reported to cause headaches, nausea, flushing, hypotension, palpitations, tachycardia, dizziness, and angina. |
| 독성 요약 | Published reports of toxicity with acute use of hydralazine are uncommon. Signs of toxicity include hypotension, tachycardia, headaches, and generalized flushing. Chronic toxicity could lead to DILE. There is no specific treatment for an overdose other than supportive therapy. Fluids should be given initially, followed by vasopressors if hypotension persists despite fluid resuscitation. Tachycardia or ischemia can be treated with beta-blockers with attention to blood pressure prior to administration. |
