Conversely, dmgs that indnce P450 enzymes increase theophylline clearance and lower blood concentrations. These inclnde the barbitnrates, phenjdoin, carbamaze-pine, and rifampicin. Increased clearance also occnrs with a high-protein diet, marijnana, and tobacco. With phenytoin the interaction is two-sided the plasma concentrations of both dmgs fall. This can resnlt in poor seiznre and respiratory control and in dmg toxicity. 

Urinary pH can be important in determining dmg toxicity more directly. A preparation containing methenamine mandelate and sul-famethizole caused turbidity in the urine of 9 out of 32 patients. The mrbidity was higher in acidic urine, and was caused by precipitation of an amorphous sulfonamide derivative containing 63% of sulfamethizole. In vitro, methenamine causes the precipitation of the sulfonamide at pH values from 5 to 6. The... 

Wliile die patient is receiving a cholinergic dmg it is important for the nurse to monitor for dmg toxicity or cholinergic crisis. 

The Mazzotti reaction is due to the killing action of ivermectin on microfilariae and its intensity correlates with skin microfilaria load. It occurs more frequently and with greater severity in nonindigenous persons than in the indigenous inhabitants of endemic areas. The reaction will occur with any dmg capable of killing microfilariae, and it is not a dmg toxicity. The answer is (C). 

Kidney disease decreases the glomerular filtration rate (GFR) and thereby reduces the quantity of dmgs that can be eliminated by the kidneys. This can result in dmg toxicity. A similar effect can be caused by a decrease in bloodflow to the kidneys.

A monse popnlation-based approach may also be employed to inform the mode of action for dmg toxicity. A recent demonstration of this apphcation is a stndy that ntilized a panel of inbred strains to investigate the molecnlar mechanisms of genetic sensitivity to isoniazid-induced steatosis (Church et al., 2014). The study was conducted as a consortia effort by manbers of the Health and Environmental Sciences Institute (HESl) s Apphcation of Genomics to Mechanism-based Risk Assessment Technical Committee. In that study, a combined transcriptontic, metabolomic, and pharmacoge-netic analysis was utilized to provide evidence for a novel hypothesis that isoniazid increases the capacity for formation of lipid droplets while concurrently reducing the capacity for exporting stored fat from the hepatocytes in sensitive strains. 

The presence of numerous foamy macrophages or foamy epithelial cells is sometimes seen in drug-associated acute lung injury (6). With either CVDs or dmg toxicity, clinical correlation is required for the diagnosis. 

Cyclophosphamide is an alkylating agent used in a variety of malignant, inflammatory, and autoimmune diseases. The prevalence of dmg toxicity is low, likely...
