Cyclo?

  #5

its cyclosporine it causes nephrotoxicity & hypertension

why not the others :

penicillin would cause acute hypersensitivite interstitial nephritis
gentamicin causes toxic ATN but that would be acute too & it would involve the tubule mainly - gentamicin --> myeloid bodies in PCT cells-
naproxen may cause chronic analgesic nephropathy but that would first manifest as papillary necorsis
cyclophosphamide causes cyctitis (distractor)
