Interactions between your drugs

Moderate

chlorpheniramine berotralstat

Applies to: chlorpheniramine / ibuprofen / pseudoephedrine and berotralstat

MONITOR: Coadministration with berotralstat may increase the plasma concentrations and effects of drugs that are substrates of CYP450 3A4 and/or 2D6. The mechanism is decreased clearance due to inhibition of CYP450 3A4 and 2D6 activity by berotralstat. Berotralstat is considered a moderate inhibitor of CYP450 3A4 and 2D6. In drug interaction studies, berotralstat reportedly increased the peak plasma concentration (Cmax) and systemic exposure (AUC) of the sensitive CYP450 3A4 substrate midazolam by approximately 1.5-fold and 2.25-fold, respectively, and the CYP450 3A4 substrate amlodipine by approximately 1.5-fold and 1.75-fold, respectively. It increased the Cmax and AUC of the sensitive CYP450 2D6 substrate dextromethorphan by approximately 2.9-fold and 2.7-fold, respectively, and the CYP450 2D6 substrate desipramine by 1.7-fold and 1.9-fold, respectively. Clinical data are not available.

MANAGEMENT: Caution is advised when berotralstat is coadministered with drugs that are substrates of CYP450 3A4 and/or 2D6, particularly those with a narrow therapeutic index. Clinical and laboratory monitoring are recommended following the initiation of berotralstat, and the individual dosages of the concomitant agents adjusted as needed.

Drug and food interactions

Moderate

chlorpheniramine food

Applies to: chlorpheniramine / ibuprofen / pseudoephedrine

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Moderate

ibuprofen food

Applies to: chlorpheniramine / ibuprofen / pseudoephedrine

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

pseudoephedrine food

Applies to: chlorpheniramine / ibuprofen / pseudoephedrine

MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.

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.
