Interactions between your drugs

Moderate

ketorolac PHYSostigmine

Applies to: RCK (clonidine / ketorolac / ropivacaine) and physostigmine

MONITOR: The concomitant use of acetylcholinesterase inhibitors (ACHEIs) (e.g., donepezil, galantamine, benzgalantamine physostigmine, rivastigmine, tacrine) with nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk of gastrointestinal (GI) bleeding. ACHEIs can increase gastric acid secretion due to their cholinergic effects and NSAIDS may increase the risk of GI bleeding and ulceration. In a Swedish retrospective case study of 70,060 patients aged 65 years and older with new prescriptions for both ACHEIs and NSAIDs, 1500 persons were diagnosed with incident peptic ulcer. The results suggested that the risk of peptic ulcer was significantly increased for the combination of ACHEIs and NSAIDs compared to NSAIDs alone. No increased risks were found for the use of ACHEIs alone.


MANAGEMENT: Caution and clinical monitoring are recommended if concomitant use of ACHEIs and NSAIDs is required, especially in patients with a prior history of peptic ulcer disease, the elderly, or debilitated patients. Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence gastrointestinal bleeding such as black or tarry stools, bright red blood in vomit, coffee ground like vomit, abdominal pain or cramping, diarrhea, dizziness or lightheadedness, weakness or fatigue and pale skin.

Drug and food interactions

Moderate

cloNIDine food

Applies to: RCK (clonidine / ketorolac / ropivacaine)

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. Patients should also avoid driving or operating hazardous machinery until they know how the medications affect them.

ketorolac food

Applies to: RCK (clonidine / ketorolac / ropivacaine)

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.

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.
