Interaction between Diflunisal and Insulin aspart (aspart protamine)
Moderate
Synergy
| ID | DDInter551 and DDInter928 |
| Interaction | The hypoglycemic effect of insulin may be potentiated by certain drugs, including ACE inhibitors, angiotensin receptor blockers (ARBs), 4-aminoquinolines, amylin analogs, anabolic steroids, fibrates, monoamine oxidase inhibitors (MAOIs, including linezolid), salicylates, selective serotonin reuptake inhibitors (SSRIs), sulfonamides, disopyramide, propoxyphene, quinidine, quinine, and ginseng. These drugs may increase the risk of hypoglycemia by enhancing insulin sensitivity (ACE inhibitors, ARBs, fibrates, ginseng); stimulating insulin secretion (salicylates, disopyramide, pentoxifylline, propoxyphene, quinidine, quinine, MAOIs, ginseng); decreasing insulin clearance and resistance (4-aminoquinolines); increasing peripheral glucose utilization (SSRIs, insulin-like growth factor); inhibiting gluconeogenesis (SSRIs, MAOIs, insulin-like growth factor); slowing the rate of gastric emptying (amylin analogs); and/or suppressing postprandial glucagon secretion (amylin analogs). Clinical hypoglycemia has been reported during use of some of these agents alone or with insulin and/or insulin secretagogues. |
| Management | Close monitoring for the development of hypoglycemia is recommended if these drugs are coadministered with insulin, particularly in patients with advanced age and/or renal impairment. The insulin dosage may require adjustment if an interaction is suspected. Patients should be apprised of the signs and symptoms of hypoglycemia (e.g., headache, dizziness, drowsiness, nausea, hunger, tremor, weakness, sweating, palpitations). |

Potential Metabolism Interactions
Substrate-Substrate Interaction：If more than one drug is metabolized by the same CYP, it is possible that its metabolism is inhibited because of the competition between the drugs. That means, it can be useful to lower the dosage of the drugs in the drug-cocktail because they remain longer in the organism than in monotherapy.
Inhibitor-Inhibitor Interaction：Combining two or more inhibitors of one CYP, should be compensated by lowering the dosage of these drugs because the metabolism is reduced and the drugs remain longer in the organism than in monotherapy. Not adapting the dosage bears the risk of even more side effects.
Inhibitor-Substrate Interaction：Combining drugs that have inhibitory effect and are substrates of one particular CYP, should be compensated by lowering the dosage. They rest longer in the organism than in monotherapy. Not adapting the dosage bears the risk of even more side effects.
