papaverine sodium sulfate

Applies to: papaverine and magnesium sulfate / potassium chloride / sodium sulfate

MONITOR: The use of bowel cleansing preparations may increase the risk of ventricular arrhythmia, particularly torsade de pointes, in patients treated with drugs that prolong the QT interval. Severe and potentially fatal cases of electrolyte disorders and arrhythmias have been reported in elderly patients using bowel cleansing products. Electrolyte disturbances including hypokalemia and hypomagnesemia are known risk factors for torsade de pointes associated with QT interval prolongation.

MANAGEMENT: Caution is advised when bowel cleansing preparations are prescribed in patients treated with drugs that prolong the QT interval. Monitoring of baseline and posttreatment serum electrolyte levels is recommended, particularly in the elderly. Patients should be instructed to drink plenty of clear liquids before, during, and after the bowel preparation process. Consideration should be given to consumption of 36 to 48 fluid ounces of a carbohydrate-electrolyte solution in the six hours before the first dose. Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.

Drug and food interactions

Moderate

sodium sulfate food

Applies to: magnesium sulfate / potassium chloride / sodium sulfate

ADJUST DOSING INTERVAL: Bowel cleansing products can increase the gastrointestinal transit rate. Oral medications administered within one hour of the start of administration of the bowel cleansing solution may be flushed from the gastrointestinal tract and not properly absorbed.

MANAGEMENT: Patients should be advised that absorption of oral medications may be impaired during bowel cleansing treatment. Oral medications (e.g., anticonvulsants, oral contraceptives, antidiabetic agents, antibiotics) should not be administered during and within one hour of starting bowel cleansing treatment whenever possible. However, if concomitant use cannot be avoided, monitoring for reduced therapeutic effects may be advisable.

MONITOR: Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.

MANAGEMENT: Caution and close monitoring for development of hypotension is advised during coadministration of these agents. Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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 interaction information available.
