Drug interactions

Moderate drug interactions

Moderate:

quiNIDine pretomanid

Applies to: Quin-G (quinidine) and pretomanid

Pretomanid may increase the blood levels of quiNIDine, which may cause you to have more side effects from the medication that you are taking to treat your condition. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

quiNIDine Food/Lifestyle

Applies to: Quin-G (quinidine)

Do not consume grapefruit or grapefruit juice during treatment with quiNIDine unless specifically directed otherwise by your doctor. Grapefruit and grapefruit juice can interact with quiNIDine and increase the levels of quiNIDine in your body. If you are already consuming grapefruit products, do not increase or decrease the amount of these products in your diet without first talking to your doctor.

Moderate:

pretomanid Food/Lifestyle

Applies to: pretomanid

Food can enhance the levels of pretomanid in your body. Pretomanid should be taken just after eating food. Do not take it on an empty stomach. This will make it easier for your body to absorb the medication. Swallow tablets whole. Do not crush, chew, or break the tablets.

Disease interactions

14 potential interactions Applies to: 12 conditions, including Heart Failure, Hypokalemia, Hypotension, Myasthenia Gravis, and Urinary Retention.

Alcoholism

Moderate:

pretomanid

Pretomanid has a moderate potential interaction with Alcoholism.

The effect of liver dysfunction on the safety, effectiveness, and pharmacokinetics of pretomanid has not been established. The combination regimen of pretomanid, bedaquiline, and linezolid has been associated with hepatic adverse reactions; alcohol and hepatotoxic agents should be avoided during pretomanid treatment, especially in patients with liver dysfunction. It is recommended to monitor signs and symptoms of hepatotoxicity and laboratory tests (ALT, AST, alkaline phosphatase, and bilirubin) at least at baseline, at 2 weeks, and then monthly while on treatment and as needed. If evidence of new or worsening liver dysfunction occurs, it is recommended to test for viral hepatitides and discontinue other hepatotoxic medications.

Glaucoma/Intraocular Hypertension

Major:

Quin-G

The quiNIDine in Quin-G has a major potential interaction with Glaucoma/Intraocular Hypertension.

The use of quinidine is contraindicated in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as myasthenia gravis, glaucoma, and urinary retention or obstruction.

Heart Block

Major:

Quin-G

The quiNIDine in Quin-G has a major potential interaction with Heart Block.

The use of quinidine is contraindicated for use in patients without a functioning artificial pacemaker whose cardiac rhythm is dependent upon a junctional or idioventricular pacemaker, including patients with complete AV block. Therapy with quinidine should be administered with caution in patients with severe sinus-node dysfunction such as sick sinus syndrome, bradycardia-tachycardia syndrome, or second- or third-degree heart block.

Heart Failure

Major:

Quin-G

The quiNIDine in Quin-G has a major potential interaction with Heart Failure.

Antiarrhythmic agents can induce severe hypotension (particularly with IV administration) or induce or worsen congestive heart failure (CHF). Patients with primary cardiomyopathy or inadequately compensated CHF are at increased risk. Antiarrhythmic agents should be administered cautiously and dosage and/or frequency of administration modified in patients with hypotension or adequately compensated CHF. Alternative therapy should be considered unless these conditions are secondary to cardiac arrhythmia.

Hyperkalemia

Moderate:

Quin-G

The quiNIDine in Quin-G has a moderate potential interaction with Hyperkalemia.

Electrolyte imbalance can alter the therapeutic effectiveness of antiarrhythmic agents. Hypokalemia and hypomagnesemia can reduce the effectiveness of antiarrhythmic agents. In some cases, these disorders can exaggerate the degree of QTc prolongation and increase the potential for torsade de pointes. Hyperkalemia can potentiate the toxic effects of antiarrhythmic agents. Electrolyte imbalance should be corrected prior to initiating antiarrhythmic therapy. Clinical monitoring of cardiac function and electrolyte concentrations is recommended.

Hypokalemia

Moderate:

Quin-G

The quiNIDine in Quin-G has a moderate potential interaction with Hypokalemia.

Electrolyte imbalance can alter the therapeutic effectiveness of antiarrhythmic agents. Hypokalemia and hypomagnesemia can reduce the effectiveness of antiarrhythmic agents. In some cases, these disorders can exaggerate the degree of QTc prolongation and increase the potential for torsade de pointes. Hyperkalemia can potentiate the toxic effects of antiarrhythmic agents. Electrolyte imbalance should be corrected prior to initiating antiarrhythmic therapy. Clinical monitoring of cardiac function and electrolyte concentrations is recommended.

Hypotension

Major:

Quin-G

The quiNIDine in Quin-G has a major potential interaction with Hypotension.

Antiarrhythmic agents can induce severe hypotension (particularly with IV administration) or induce or worsen congestive heart failure (CHF). Patients with primary cardiomyopathy or inadequately compensated CHF are at increased risk. Antiarrhythmic agents should be administered cautiously and dosage and/or frequency of administration modified in patients with hypotension or adequately compensated CHF. Alternative therapy should be considered unless these conditions are secondary to cardiac arrhythmia.

Liver Disease

Moderate:

pretomanid

Pretomanid has a moderate potential interaction with Liver Disease.

The effect of liver dysfunction on the safety, effectiveness, and pharmacokinetics of pretomanid has not been established. The combination regimen of pretomanid, bedaquiline, and linezolid has been associated with hepatic adverse reactions; alcohol and hepatotoxic agents should be avoided during pretomanid treatment, especially in patients with liver dysfunction. It is recommended to monitor signs and symptoms of hepatotoxicity and laboratory tests (ALT, AST, alkaline phosphatase, and bilirubin) at least at baseline, at 2 weeks, and then monthly while on treatment and as needed. If evidence of new or worsening liver dysfunction occurs, it is recommended to test for viral hepatitides and discontinue other hepatotoxic medications.

Moderate:

Quin-G

The quiNIDine in Quin-G has a moderate potential interaction with Liver Disease.

Quinidine is primarily metabolized by the liver to active and inactive forms. Hepatic dysfunction causes a slowed metabolism and elimination of the drug which can lead to quinidine toxicity if dosage is not appropriately reduced. Clinical monitoring of hepatic function is recommended.

Magnesium Imbalance

Moderate:

Quin-G

The quiNIDine in Quin-G has a moderate potential interaction with Magnesium Imbalance.

Electrolyte imbalance can alter the therapeutic effectiveness of antiarrhythmic agents. Hypokalemia and hypomagnesemia can reduce the effectiveness of antiarrhythmic agents. In some cases, these disorders can exaggerate the degree of QTc prolongation and increase the potential for torsade de pointes. Hyperkalemia can potentiate the toxic effects of antiarrhythmic agents. Electrolyte imbalance should be corrected prior to initiating antiarrhythmic therapy. Clinical monitoring of cardiac function and electrolyte concentrations is recommended.

Myasthenia Gravis

Major:

Quin-G

The quiNIDine in Quin-G has a major potential interaction with Myasthenia Gravis.

The use of quinidine is contraindicated in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as myasthenia gravis, glaucoma, and urinary retention or obstruction.

Renal Dysfunction

Moderate:

pretomanid

Pretomanid has a moderate potential interaction with Renal Dysfunction.

The effect of renal dysfunction on the safety, effectiveness, and pharmacokinetics of pretomanid has not been established.

Moderate:

Quin-G

The quiNIDine in Quin-G has a moderate potential interaction with Renal Dysfunction.

Renal dysfunction causes a slowed elimination of quinidine which can lead to quinidine toxicity if dosage is not appropriately reduced. Therapy with quinidine should be administered cautiously and dosages reduced in patients with compromised renal function. Quinidine is not appreciably removed by hemodialysis.

Urinary Retention

Major:

Quin-G

The quiNIDine in Quin-G has a major potential interaction with Urinary Retention.

The use of quinidine is contraindicated in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as myasthenia gravis, glaucoma, and urinary retention or obstruction.
