desmopressin dihydrocodeine

Applies to: desmopressin and aspirin / caffeine / dihydrocodeine

MONITOR: Coadministration with opiates may increase the plasma concentrations and pharmacologic effects of oral desmopressin. The risk of water intoxication and/or hyponatremia may be increased. In 18 healthy subjects, loperamide 4 mg given at 24 hours, 12 hours, and 1 hour before a single 400 mcg oral dose of desmopressin increased the peak plasma concentration (Cmax) of desmopressin by 2.3-fold and its systemic exposure (AUC) by 3.1-fold. Pretreatment with loperamide also increased the median time to reach peak desmopressin concentration (Tmax) from 1.3 to 2 hours, but did not affect the terminal elimination half-life. Although not investigated, other opiates may interact similarly with desmopressin by slowing gastrointestinal motility. In addition, some opiate analgesics such as fentanyl, meperidine, morphine, oxycodone, and tramadol have been associated with reports of hyponatremia, sometimes secondary to the syndrome of inappropriate antidiuretic hormone secretion (SIADH). These effects may be additive with those of desmopressin and probably stem from agonist action on morphinic receptors, resulting in increased release of antidiuretic hormone.

MANAGEMENT: Caution is recommended if desmopressin is used in combination with opiates. Serum electrolytes, especially sodium, as well as BUN and creatinine should be monitored regularly. Patients should be advised to seek immediate medical attention if they develop early signs and symptoms of water intoxication or hyponatremia such as anorexia, nausea, vomiting, drowsiness, lethargy, weakness, listlessness, headache, confusion, difficulty concentrating, memory impairment, anuria, and weight gain. Early treatment may help prevent progression to seizure, coma, respiratory arrest, and death.

aspirin desmopressin

Applies to: aspirin / caffeine / dihydrocodeine and desmopressin

Limited data have shown that desmopressin (DDAVP) can significantly reduce aspirin-induced increases in bleeding times. The DDAVP effect on bleeding time correlates closely with increases in the plasma concentration of von Willebrand factor. The clinical consequences of this interaction are not known.

One study has reported that coadministration of caffeine and aspirin lead to a 25% increase in the rate of appearance and 17% increase in maximum concentration of salicylate in the plasma. A significantly higher area under the plasma concentration time curve of salicylate was also reported when both drugs were administered together. The exact mechanism of this interaction has not been specified. Physicians and patients should be aware that coadministration of aspirin and caffeine may lead to higher salicylate levels faster.

Drug and food interactions

Moderate

aspirin food

Applies to: aspirin / caffeine / dihydrocodeine

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.

desmopressin food

Applies to: desmopressin

Food may decrease the rate and extent of absorption of desmopressin following oral administration. In 16 healthy, nonsmoking volunteers, administration of a single 400 mcg oral dose of desmopressin concomitantly with a standardized meal (27% fat) resulted in a 52% decrease in the peak plasma concentration (Cmax) of desmopressin and a 43% decrease in systemic exposure (AUC) compared to administration in the fasting state. The Cmax and AUC were still reduced by 46% and 41%, respectively, when desmopressin was administered 1.5 hours after eating. Both feeding regimens prolonged the time to reach peak plasma concentration (Tmax) from 1 hour to 1.5 hours. However, the pharmacodynamic effects of desmopressin were not affected as assessed by urine volume and osmolality for at least 4 hours postdose. The degree of antidiuresis was similar in the absence of food and when the drug was taken with or 1.5 hours after eating. These findings would suggest a fairly minor clinical impact of the interaction in most patients, especially since oral desmopressin is intended for administration at bedtime. Nevertheless, the possibility of food effects should be considered before increasing the dose whenever a diminution of effect is noted. A significant interaction is not expected to occur with the sublingual formulation, since absorption occurs primarily in the oral mucosa, pharynx, and esophagus.

caffeine food

Applies to: aspirin / caffeine / dihydrocodeine

The effect of grapefruit juice on the pharmacologic activity of caffeine is controversial. One report suggests that grapefruit juice increases the effect of caffeine. The proposed mechanism is inhibition of cytochrome P-450 metabolism of caffeine. However, a well-conducted pharmacokinetic/pharmacodynamic study did not demonstrate this effect. The clinical significance of this potential interaction is unknown.

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.
