Disease interactions
13 potential interactions Applies to: 11 conditions, including Seizures, Arrhythmia, Hypokalemia, Myasthenia Gravis, and Tinnitus.
Arrhythmia
Major:
quinine
quiNINE has a major potential interaction with Arrhythmia.
The use of certain antimalarial agents is contraindicated in patients with known prolongation of QT interval as these patients can develop fatal arrhythmias. These drugs should also be avoided in patients with clinical conditions known to prolong the QT interval, such as uncorrected hypokalemia or hypomagnesemia, bradycardia, and certain other cardiac conditions. Caution is advised in patients taking other medications that can prolong the QT interval.
G-6-PD Deficiency
Major:
quinine
quiNINE has a major potential interaction with G-6-PD Deficiency.
The use of quinine is contraindicated in patients with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency. Red blood cells are more easily destroyed in patients with G-6-PD deficiency and may lead to hemolysis and anemia.
Hypokalemia
Major:
quinine
quiNINE has a major potential interaction with Hypokalemia.
The use of certain antimalarial agents is contraindicated in patients with known prolongation of QT interval as these patients can develop fatal arrhythmias. These drugs should also be avoided in patients with clinical conditions known to prolong the QT interval, such as uncorrected hypokalemia or hypomagnesemia, bradycardia, and certain other cardiac conditions. Caution is advised in patients taking other medications that can prolong the QT interval.
Liver Disease
Moderate:
quinine
quiNINE has a moderate potential interaction with Liver Disease.
In patients with severe hepatic impairment (Child-Pugh C), quinine oral clearance is decreased, volume of distribution is increased, and half-life is prolonged, relative to subjects with normal liver function. Therefore, quinine is not indicated in patients with severe hepatic impairment and alternate therapy should be administered. Adjustment of the recommended dose is not required in mild (Child-Pugh A) or moderate (Child-Pugh B) hepatic impairment, but patients should be monitored closely for adverse effects of quinine.
Moderate:
treosulfan
Treosulfan has a moderate potential interaction with Liver Disease.
Treosulfan has not been studied in patients with moderate or severe liver and renal dysfunction.
Magnesium Imbalance
Major:
quinine
quiNINE has a major potential interaction with Magnesium Imbalance.
The use of certain antimalarial agents is contraindicated in patients with known prolongation of QT interval as these patients can develop fatal arrhythmias. These drugs should also be avoided in patients with clinical conditions known to prolong the QT interval, such as uncorrected hypokalemia or hypomagnesemia, bradycardia, and certain other cardiac conditions. Caution is advised in patients taking other medications that can prolong the QT interval.
Myasthenia Gravis
Major:
quinine
quiNINE has a major potential interaction with Myasthenia Gravis.
The use of quinine is contraindicated in patients with myasthenia gravis, as quinine has neuromuscular blocking activity, and may exacerbate muscle weakness.
Renal Dysfunction
Moderate:
quinine
quiNINE has a moderate potential interaction with Renal Dysfunction.
Clearance of quinine is decreased in patients with severe chronic renal failure. The dosage and dosing frequency should be reduced. The effects of mild and moderate renal impairment on the safety and pharmacokinetics of quinine sulfate are not known. Monitoring is advised.
Moderate:
treosulfan
Treosulfan has a moderate potential interaction with Renal Dysfunction.
Treosulfan has not been studied in patients with moderate or severe liver and renal dysfunction.
Seizures
Moderate:
treosulfan
Treosulfan has a moderate potential interaction with Seizures.
There have been reports of seizures in patients following treatment with treosulfan. Patients should be monitored for signs of neurological adverse reactions, and clonazepam prophylaxis may be considered for patients at higher risk for seizures, including infants.
Thrombocytopenia
Major:
quinine
quiNINE has a major potential interaction with Thrombocytopenia.
Quinine is contraindicated in patients with thrombocytopenia. Quinine can produce an immune-mediated thrombocytopenia. Severe cases of thrombocytopenia that are fatal or life threatening have been reported. Chronic renal impairment associated with the development of TTP has also been reported. Thrombocytopenia usually resolves within a week upon discontinuation of quinine. If quinine is not stopped, patients can be at risk for fatal hemorrhage. Upon re- exposure to quinine from any source, a patient with quinine- dependent antibodies could develop thrombocytopenia that is more rapid in onset and more severe than the original episode.
Tinnitus
Major:
quinine
quiNINE has a major potential interaction with Tinnitus.
The use of quinine is contraindicated in patients with tinnitus. Quinine has been associated with reversible and irreversible ototoxicity. Reversible hearing loss, tinnitus, and dizziness has been reported in 20% of patients receiving therapeutic doses of quinine. Cystic degeneration of stria vascularis, degeneration of the cochlear neurons, and loss of hair cells occur. Injury may be produced by spasm of cochlear blood vessels, resulting in anoxia and subsequent cellular damage.
Visual Defect/Disturbance
Major:
quinine
quiNINE has a major potential interaction with Visual Defect/Disturbance.
The use of quinine is contraindicated in patients with optic neuritis, and cautious use, if at all, is advised for patients with retinopathy or other visual defects. Quinine may affect the retina and optic nerve, producing visual disturbances that include blurred vision with scotomata, photophobia, diplopia, constricted visual fields, night blindness, and abnormal color perception. Although ocular toxicity is usually reversible following drug withdrawal, retinopathy and optic atrophy can occur in severe cases. All patients should be advised to immediately discontinue the drug and contact a physician if visual disturbances occur or are exacerbated during quinine therapy.
