Interactions between your drugs

Moderate

pegvisomant pramlintide

Applies to: pegvisomant and pramlintide

MONITOR: Treatment with pegvisomant may increase glucose tolerance in some diabetic patients, potentially reducing their requirements for insulin and other antidiabetic agents. The mechanism is pegvisomant antagonism of endogenous growth hormone, the latter of which normally decreases insulin sensitivity and opposes the effects of insulin on carbohydrate metabolism. However, clinically relevant hypoglycemia was not observed in diabetic patients who were treated with pegvisomant in premarketing trials.

MANAGEMENT: Close clinical monitoring of glycemic control is recommended when pegvisomant is used in patients receiving insulin or other antidiabetic agents, and the dosages of these agents adjusted as necessary. Likewise, patients may be at risk for hyperglycemia when pegvisomant is withdrawn from their therapeutic regimen.

Drug and food interactions

Moderate

pramlintide food

Applies to: pramlintide

ADJUST DOSING INTERVAL: Pramlintide slows gastric emptying and may delay the absorption of concomitantly administered oral medications. In a pharmacokinetic study of 24 patients with type 2 diabetes, coadministration with pramlintide (120 mcg) decreased the peak plasma concentration (Cmax) of acetaminophen (1000 mg) by 29% and increased its time to peak plasma concentration (Tmax) based on the time of acetaminophen administration relative to pramlintide injection. Pramlintide significantly increased acetaminophen Tmax (range 48 to 72 minutes) when acetaminophen was administered simultaneously with or up to 2 hours following pramlintide injection, but it had negligible effect when acetaminophen was administered 1 to 2 hours before pramlintide injection.

MANAGEMENT: When rapid onset of a concomitantly administered oral medication is critical to its effectiveness, the medication should be administered at least 1 hour before or 2 hours after pramlintide injection.

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.
