A | B |
Ceftriaxone, cefotaxime-3rd generation cephalosporins- | interfere with cell wall synthesis |
Chloramphenicol- | inhibits microbial protein synthesis |
Pen G | interferes with cell wall synthesis; good for gram negative |
Rifampin | -inhibits RNA synthesis |
N. Meningitidis | First choice: Penicillin |
L. Monocytogenes | First choice:Ampicillin |
H. Influenzae | First choice: Ceftriaxone, Cefotaxime |
S. Pneumoniae | First choice: Penicillin G, Vancomycin |
S. Pneumoniae | Second Choice: Chloramphenicol |
H. Influenzae | Second Choice: Chloramphenicol |
L. Monocytogenes | Second Choice: Trimethoprim sulfamethoxazole |
N. Meningitidis | Second Choice: Ceftriaxone, Cefotaxime |
used as prophylactic therapy for those in contact with cases of bacterial meningitis; kills carrier state | Rimfampin |
3rd generation cephalosporins (cefotaxime, ceftriaxone) are good alternative treatments due to their ability to penetrate the CNS | In cases of bacterial meningitis caused by N. Meningitidis |
Eflornithine | Treats early and late stage of T. brucei gambiense only |
Pentamidine | Early stage of T. brucei gambiense only |
Suramin | Early stage of T. brucei rhodesiense and T. brucei gambiense |
Melarsoprol | Usually given after administering suramin; Late stage of T. brucei rhodesiense and T. brucei gambiense |
Nifurtimox | First choice for use with T. Cruzi |
Benznidazole | Second choice for use with T. Cruzi |
Late stage= | CNS phase of the disease |
fewer side effects than melarsoprol | Eflornithine |
Antiprotozoals-drugs for tx of p. jiroveci | Atovaquone, Trimethoprim-sulfamethoxazole, Pentamidine |
Clindamycin plus pyrimethamine | second line regimin for p.jiroveci |
Good for pts that can’t tolerate trimethoprim-sulfamethoxazole | Pentamidine |
Primary antiprotozoal tx used to treat toxoplasmosis | Pyrimethamine-sulfadiazene |
Azithromycin, Clarithromycin, Atovaquone, Dapsone | Any one of these drugs may be given in combination with pyrimethamine-sulfadiazene or trimethoprimsulfamethoxazole |
Spiramycin | For acute toxo infection during pregnancy; concentrates in placenta |
inhibits DHFA reductase of protozoa | Pyrimethamine-sulfadiazene |
given with folinic acid to counteract toxicity | Pyrimethamine-sulfadiazene |
Alternative to pyrimethamine-sulfadiazene | Clindamycin |
Macrolides: clindamycin, azithromycin, clarithromycin | -inhibit bacterial protein synthesis by blocking 50S |
Atovaquone | interferes with mitochondrial function |
Dapsone | inhibits nucleic acid synthesis (inhibits dihydropteroate synthase and decreases use of p-aminobenzoic acid) |
Tri-sulf | inhibts DHFAR-bacteriocidal |
inhibits RNA synthesis by binding to bacterial RNA-pol- bacteriocidal | Rifampin |
Clarithromycin | has good activity against Leprosy |
Ethionamide | Given as an inactive pro-drug that ultimately inhibits cell wall synthesis-can sub for clofazimine-often used as a 2ndary agent |
Drugs used to treat leprosy | Dapsone,Rifampin,Clofazimine,Clarithromycin,Ethionamide |
Dapsone | bacteriostatic |
Viral encephalitis | acyclovir |
Rabies | prophylactic treatment postexposure |
Rabies | hyperimmune globulin, human diploid cell vaccine |
