Apresoline (hydralazine) Disease Interactions

There are 5 disease interactions with Apresoline (hydralazine):


Hydralazine (Includes Apresoline) ↔ Bone Marrow Suppression

Severe Potential Hazard, Low plausibility

Applies to: Bone Marrow Depression/Low Blood Counts

Hydralazine may rarely cause blood dyscrasias at recommended dosages. Reduction in hemoglobin, red cell count, agranulocytosis, leukopenia, and purpura have been reported. Therapy with hydralazine should be administered cautiously in patients with these preexisting conditions and if such abnormalities develop during the course of therapy, treatment should be discontinued. Monitoring blood counts should be considered for those patients at higher risk.

Hydralazine (Includes Apresoline) ↔ Coronary Artery Disease

Severe Potential Hazard, High plausibility

Applies to: Ischemic Heart Disease

The use of hydralazine is contraindicated in patients with coronary artery disease. Reflex tachycardia may commonly occur. Palpitations and chest pain have also been reported. Myocardial infarction has been associated with the use of hydralazine.

Hydralazine (Includes Apresoline) ↔ Lupus Erythematosus

Severe Potential Hazard, High plausibility

Applies to: Lupus Erythematosus

The use of hydralazine has been associated with the development of lupus erythematosus and lupus-like syndromes, as well as exacerbation of the disease. Hydralazine therapy should be withdrawn in patients experiencing worsening of preexisting lupus. Monitoring complete blood counts, and antinuclear antibody titers before and during prolonged therapy is recommended.

Hydralazine (Includes Apresoline) ↔ Renal Dysfunction

Moderate Potential Hazard, Moderate plausibility

Applies to: Glomerulonephritis, Renal Dysfunction

The use of hydralazine has been associated with the development of glomerulonephritis. Hydralazine should be used with caution in patients with advanced renal damage and these patients may required a lower dose. Renal function should be monitored and supported as required.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.
