Carbamazepine Cyclosporine

Drugs in Class II have low aqueous solubility (but high membrane permeability), and any factor affecting dissolution rate would be expected to have an impact on the absorption of such compounds. Factors that are noted in Fig. 11, such as fluid pH, volume and viscosity, and bile secretion (especially in response to fatty foods), might be expected to play a role in dissolution rate and thereby affect absorption. Compounds that fall into this class include carbamazepine, cyclosporin, digoxin, griseofulvin, and spironolactone. Food would be expected to exert a potentially significant affect on... 

Drugs that maybe affected by danazol are carbamazepine, cyclosporine, and warfarin. 

Multiple drug interactions have been discribed (decreased serum concentrations of phenobarbital, phenytoin, sulfinpyrazone and rifampin, increased serum concentrations of quinidine, carbamazepine, cyclosporin). Important in this setting is that a marked interaction exists between digoxin and verapamil, increasing the serum concentrations of the former due to decreased renal excretion,...
