AIN due to the sulfa component is far more common. Macrolides - Erythromycin, Clarithromycin, Azithromycin-50S … Adults: One double-strength or two regular-strength tablets P.O. The mechanism of nephrotoxicity involves direct cell membrane actions to increase permeability, as well as indirect effects secondary to activation of intrarenal mechanisms (tubuloglomerular feedback) and/or release of mediators (thromboxane A 2). Bactrim may inhibit the hepatic metabolism of phenytoin (a CYP2C9 substrate). The major classes of antibiotics include: aminoglycosides, penicillins and penicillinase-resistant drugs, sulfonamides, tetracyclines, and antimycobacterials (e.g. 160 mg trimethoprim/800 mg sulfamethoxazole PO once daily or 80 mg trimethoprim/400 mg sulfamethoxazole PO once daily. Nephrotoxicity is one of the key mechanisms by which pharmacodynamic drug interactions occur with AmB. Drug-induced nephrotoxicity is a renal dysfunction that occurs as a result of exposure to nephrotoxic drugs. Sulfamethoxazole is a known substrate and competitive inhibitor of CYP2C9, the enzyme most responsible for the metabolism of the most potent form of warfarin (i.e., S-warfarin). Pentamidine is an antimicrobial medication used to treat African trypanosomiasis, leishmaniasis, Balamuthia infections, babesiosis, and to prevent and treat pneumocystis pneumonia (PCP) in people with poor immune function.
