MISSED DOSE: If you miss a dose, take it as soon as you remember. Crofelemer has the potential to inhibit CYP3A4 at concentrations expected in the gut; unlikely to inhibit systemically because minimally absorbed. The approximate onset and duration of action of various dosage forms of isosorbide dinitrate (ISDN) and isosorbide mononitrate (ISMN) are as follows: Onset and duration of action following intrabuccal administration are probably similar to those after sublingual administration of isosorbide dinitrate. This drug is available at a middle level co-pay. Use Caution/Monitor. Attempts to overcome nitrate tolerance by dose escalation, even to doses far in excess of those used acutely, have consistently failed. Warn all patients receiving organic nitrates or nitrites about the potential interaction between the drugs and selective PDE inhibitors, even if they currently are not receiving the drugs, since there is substantial potential for patients to receive the drugs from another clinician, from a friend, with little or no clinical intervention (e.g., via the Internet), or illicitly.
