Drug interactions

Moderate drug interactions

Moderate:

alteplase diclofenac topical

Applies to: alteplase and Trixylitral (diclofenac / lidocaine topical)
Monitor

Systemically and topically administered nonsteroidal anti-inflammatory drugs (NSAIDs) may potentiate the risk of bleeding in patients treated with anticoagulants and other drugs that affect hemostasis such as platelet inhibitors, thrombin inhibitors, thrombolytic agents, or agents that commonly cause thrombocytopenia. The pharmacologic effects of NSAIDs that contribute to this interaction include prolongation of prothrombin time and inhibition of platelet adhesion and aggregation.

Management

Caution is advised if NSAIDs are used in combination with other drugs that affect hemostasis. Close clinical and laboratory observation for hematologic complications is recommended. Patients should be advised to promptly report any signs of bleeding to their doctor, including pain, swelling, headache, dizziness, weakness, prolonged bleeding from cuts, increased menstrual flow, vaginal bleeding, nosebleeds, bleeding of gums from brushing, unusual bleeding or bruising, red or brown urine, or red or black stools.

Food/lifestyle interactions

Minor food/lifestyle interactions

Minor:

lidocaine topical Food/Lifestyle

Applies to: Trixylitral (diclofenac / lidocaine topical)

Theoretically, grapefruit, grapefruit juice, grapefruit hybrids, starfruit, and Seville oranges may increase the plasma concentrations of topical lidocaine. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Inhibition of hepatic CYP450 3A4 may also contribute. In a drug study when a single dose of intravenous lidocaine was coadministered with potent CYP450 3A4 inhibitors, erythromycin and itraconazole, lidocaine plasma clearance was reduced by 9 to 18% in healthy subjects. The degree of systemic absorption of topical lidocaine is dependent on the duration of application, the applied surface area, and the integrity of the application site. The risk of systemic lidocaine absorption may be greater when topical lidocaine is applied to areas of high systemic absorption (e.g., mucous membranes) with repeated doses over a long period of time. However, the clinical significance of this potential interaction is unknown.

Disease interactions

19 potential interactions Applies to: 17 conditions, including High Blood Pressure, Heart Failure, Asthma, Seizures, and Fluid Retention.

Asthma

Major:

Trixylitral

The diclofenac topical in Trixylitral has a major potential interaction with Asthma.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are contraindicated in patients with history of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs; severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients. A subpopulation of patients with asthma may have aspirin-sensitive asthma which may include chronic rhinosinusitis complicated by nasal polyps, severe potentially fatal bronchospasm, and/or intolerance to aspirin and other NSAIDs. Since cross-reactivity between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, therapy with any NSAID should be avoided in patients with this form of aspirin sensitivity. NSAIDs should be used with caution in patients with preexisting asthma (without known aspirin sensitivity), and these patients should be monitored for changes in the signs and symptoms of asthma.

Cerebral Vascular Disorder

Major:

alteplase

Alteplase has a major potential interaction with Cerebral Vascular Disorder.

The use of thrombolytics is contraindicated in patients with an active bleed (internal), trauma/surgery (recent CPR/intracranial/intraspinal surgery within 2 months), bleeding diathesis, history of cerebrovascular (CV) accident, intracranial defect (aneurysm, arteriovenous malformation, neoplasm), or severe uncontrolled arterial hypertension (SBP>180/DBP>110). Risk versus benefit should be carefully considered in the following conditions and thrombolytic therapy administered with caution in patients with recent (10 days) serious GI bleed or recent (10 days) surgical procedure (coronary bypass graft, obstetrical delivery, organ biopsy, puncture of noncompressible vessel), left heart thrombus, subacute bacterial endocarditis, hemostatic defect, CV disease, diabetic hemorrhagic retinopathy, or pregnancy. Clinical monitoring of hematopoietic, bleeding and coagulation functions is recommended prior to initiation of thrombolytic therapy. Measures of fibrinolytic activity and/or coagulation functions during infusion do not correlate with efficacy or risk of bleeding.

Coagulation Defects and Disorders

Moderate:

Trixylitral

The diclofenac topical in Trixylitral has a moderate potential interaction with Coagulation Defects and Disorders.

Nonsteroidal anti-inflammatory drugs (NSAIDs) reversibly inhibit platelet adhesion and aggregation and may prolong bleeding time in some patients. With the exception of aspirin, the platelet effects seen with most NSAIDs at usual recommended dosages are generally slight and of relatively short duration but may be more pronounced in patients with underlying hemostatic abnormalities. Thrombocytopenia has also been reported rarely during NSAID use. Therapy with NSAIDs should be administered cautiously in patients with significant active bleeding or a hemorrhagic diathesis, including hemostatic and/or coagulation defects associated with hemophilia, vitamin K deficiency, hypoprothrombinemia, thrombocytopenia, thrombocytopathy, or severe hepatic impairment. NSAIDs that selectively inhibit cyclooxygenase-2 (i.e., COX-2 inhibitors) do not appear to affect platelet function or bleeding time at indicated dosages and may be preferable if risk of bleeding is a concern.

Fluid Retention

Major:

Trixylitral

The diclofenac topical in Trixylitral has a major potential interaction with Fluid Retention.

Fluid retention and edema have been reported in association with the use of nonsteroidal anti-inflammatory drugs (NSAIDs), including some topical formulations. NSAIDs (including topicals) can lead to new onset of hypertension or worsening of preexisting hypertension, either of which can contribute to the increased incidence of cardiovascular events. NSAIDs should be used with caution in patients with preexisting fluid retention, hypertension, or history of heart failure. NSAIDs should be avoided in patients with severe heart failure unless the benefits are expected to outweigh the risk of worsening heart failure; if an NSAID is used in such patients, they should be monitored for signs of worsening heart failure. Blood pressure and cardiovascular status should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy.

Gastrointestinal Hemorrhage

Major:

alteplase

Alteplase has a major potential interaction with Gastrointestinal Hemorrhage.

The use of thrombolytics is contraindicated in patients with an active bleed (internal), trauma/surgery (recent CPR/intracranial/intraspinal surgery within 2 months), bleeding diathesis, history of cerebrovascular (CV) accident, intracranial defect (aneurysm, arteriovenous malformation, neoplasm), or severe uncontrolled arterial hypertension (SBP>180/DBP>110). Risk versus benefit should be carefully considered in the following conditions and thrombolytic therapy administered with caution in patients with recent (10 days) serious GI bleed or recent (10 days) surgical procedure (coronary bypass graft, obstetrical delivery, organ biopsy, puncture of noncompressible vessel), left heart thrombus, subacute bacterial endocarditis, hemostatic defect, CV disease, diabetic hemorrhagic retinopathy, or pregnancy. Clinical monitoring of hematopoietic, bleeding and coagulation functions is recommended prior to initiation of thrombolytic therapy. Measures of fibrinolytic activity and/or coagulation functions during infusion do not correlate with efficacy or risk of bleeding.

Heart Block

Major:

Trixylitral

The lidocaine topical in Trixylitral has a major potential interaction with Heart Block.

Lidocaine is absorbed through intact skin and mucosal membranes following topical administration. Prolonged exposure, large doses, frequent applications and/or use on compromised skin or mucosa can produce systemic effects. At high plasma levels, lidocaine can cause hypotension, bradycardia, and cardiovascular collapse. Therapy with lidocaine topical should be administered cautiously in patients with shock, sinus bradyarrhythmia, or severe heart block. The recommended dosage should not be exceeded. Children and debilitated, elderly, or acutely ill patients should be given reduced dosages commensurate with their age, weight, and physical condition.

Heart Failure

Major:

Trixylitral

The diclofenac topical in Trixylitral has a major potential interaction with Heart Failure.

Fluid retention and edema have been reported in association with the use of nonsteroidal anti-inflammatory drugs (NSAIDs), including some topical formulations. NSAIDs (including topicals) can lead to new onset of hypertension or worsening of preexisting hypertension, either of which can contribute to the increased incidence of cardiovascular events. NSAIDs should be used with caution in patients with preexisting fluid retention, hypertension, or history of heart failure. NSAIDs should be avoided in patients with severe heart failure unless the benefits are expected to outweigh the risk of worsening heart failure; if an NSAID is used in such patients, they should be monitored for signs of worsening heart failure. Blood pressure and cardiovascular status should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy.

High Blood Pressure

Major:

The use of thrombolytics is contraindicated in patients with an active bleed (internal), trauma/surgery (recent CPR/intracranial/intraspinal surgery within 2 months), bleeding diathesis, history of cerebrovascular (CV) accident, intracranial defect (aneurysm, arteriovenous malformation, neoplasm), or severe uncontrolled arterial hypertension (SBP>180/DBP>110). Risk versus benefit should be carefully considered in the following conditions and thrombolytic therapy administered with caution in patients with recent (10 days) serious GI bleed or recent (10 days) surgical procedure (coronary bypass graft, obstetrical delivery, organ biopsy, puncture of noncompressible vessel), left heart thrombus, subacute bacterial endocarditis, hemostatic defect, CV disease, diabetic hemorrhagic retinopathy, or pregnancy. Clinical monitoring of hematopoietic, bleeding and coagulation functions is recommended prior to initiation of thrombolytic therapy. Measures of fibrinolytic activity and/or coagulation functions during infusion do not correlate with efficacy or risk of bleeding.

Liver Disease

Major:

Trixylitral

The lidocaine topical in Trixylitral has a major potential interaction with Liver Disease.

Lidocaine topical is absorbed through intact skin and mucosal membranes. Prolonged exposure, large doses, and/or application to compromised skin or mucosa can result in elevated plasma concentrations of lidocaine. Lidocaine is rapidly and extensively metabolized by the liver. Less than 10% is eliminated unchanged in the urine. Several inactive and two active forms (MEGX and GX) have been identified. MEGX and GX exhibit antiarrhythmic and convulsant properties. The pharmacokinetic disposition of lidocaine is altered by changes in hepatic function, including hepatic blood flow. Therapy with lidocaine topical should be administered cautiously and dosing modified for patients with compromised hepatic function.

Renal Dysfunction

Major:

Trixylitral

The lidocaine topical in Trixylitral has a major potential interaction with Renal Dysfunction.

Lidocaine topical is absorbed through intact skin and mucosal membranes. Prolonged exposure, large doses, and/or application to compromised skin or mucosa can result in elevated plasma concentrations of lidocaine. Lidocaine is primarily eliminated by the kidney. Less than 10% is eliminated unchanged in the urine. Two active metabolites (MEGX and GX) have been identified that exhibit antiarrhythmic and convulsant properties. Serum concentrations of lidocaine and the active metabolites are increased and the half-life prolonged in patients with renal impairment. Therapy with lidocaine topical should be administered cautiously and dosing modified for repeated doses in patients with compromised renal function.

Moderate:

Trixylitral

The diclofenac topical in Trixylitral has a moderate potential interaction with Renal Dysfunction.

No information is available from controlled clinical trials regarding the use of topical diclofenac in patients with advanced renal disease. Therefore, treatment with this drug is not recommended in patients with advanced renal disease. If therapy with topical diclofenac is initiated, close monitoring of the patient's renal function is advisable.

Retinal Hemorrhage

Major:

alteplase

Alteplase has a major potential interaction with Retinal Hemorrhage.

The use of thrombolytics is contraindicated in patients with an active bleed (internal), trauma/surgery (recent CPR/intracranial/intraspinal surgery within 2 months), bleeding diathesis, history of cerebrovascular (CV) accident, intracranial defect (aneurysm, arteriovenous malformation, neoplasm), or severe uncontrolled arterial hypertension (SBP>180/DBP>110). Risk versus benefit should be carefully considered in the following conditions and thrombolytic therapy administered with caution in patients with recent (10 days) serious GI bleed or recent (10 days) surgical procedure (coronary bypass graft, obstetrical delivery, organ biopsy, puncture of noncompressible vessel), left heart thrombus, subacute bacterial endocarditis, hemostatic defect, CV disease, diabetic hemorrhagic retinopathy, or pregnancy. Clinical monitoring of hematopoietic, bleeding and coagulation functions is recommended prior to initiation of thrombolytic therapy. Measures of fibrinolytic activity and/or coagulation functions during infusion do not correlate with efficacy or risk of bleeding.

Seizures

Major:

Trixylitral

The lidocaine topical in Trixylitral has a major potential interaction with Seizures.

Lidocaine topical is absorbed through intact skin and mucosal membranes. Prolonged exposure, large doses, and/or application to compromised skin or mucosa can result in elevated plasma concentrations of lidocaine. Seizures can occur as a result of accumulation of active metabolites. Therapy with lidocaine topical should be administered cautiously to patients with or predisposed to seizure disorders.

Shock

Major:

Trixylitral

The lidocaine topical in Trixylitral has a major potential interaction with Shock.

Lidocaine is absorbed through intact skin and mucosal membranes following topical administration. Prolonged exposure, large doses, frequent applications and/or use on compromised skin or mucosa can produce systemic effects. At high plasma levels, lidocaine can cause hypotension, bradycardia, and cardiovascular collapse. Therapy with lidocaine topical should be administered cautiously in patients with shock, sinus bradyarrhythmia, or severe heart block. The recommended dosage should not be exceeded. Children and debilitated, elderly, or acutely ill patients should be given reduced dosages commensurate with their age, weight, and physical condition.

Teething Syndrome

Major:

Trixylitral

The lidocaine topical in Trixylitral has a major potential interaction with Teething Syndrome.

Topical lidocaine is not recommended to be used in teething infants and young children, as its ingestion is dangerous and potentially fatal. Ingestion of the drug has shown to result in seizures, severe brain injury, and heart problems in children.

Thrombocytopenia

Moderate:

Trixylitral

The diclofenac topical in Trixylitral has a moderate potential interaction with Thrombocytopenia.

Nonsteroidal anti-inflammatory drugs (NSAIDs) reversibly inhibit platelet adhesion and aggregation and may prolong bleeding time in some patients.
