route of
ab spectrum administration uses notes
Streptococci, Strep. Pneumonia,
benzyl Spirochetes, Clostridia, Aerobic G+ve,
penicillin- cell wall inhibitor - beta lactam
penicillin ( G+ve IV or IM (acid labile) also effective against few strains of
natural
penicillin-G) staphylococci and gonococci (
Neisseria gonorrhea)
rapidly absorbed and
penicillin-V oral excreted thus used with
procaine and benzathine
ampicillin broad spectrum oral
amoxicillin broad spectrum oral
pseuodomonas is highly
resistant so usually broad
carbenicillin
broad spectrum IV pseuodomonas infections spectrum ab are not
semisynthetic
& ticarcillin
effictive against it unless
mentioned otherwise
penicillin resistant bacteria mainly
methicillin G+ve staphylococcus aureus (until MRSA penicillinase resistant
emerged)
oxacillin,
cloxacillin, G+ve antistaphylococcal penicillinase resistant
nafcillin
1- clavulanic acid and tazobactam are used in combination with penicillins to overcome (inhibit) penicillinases and they have
no other antimicrobial effect. 2- benzathine penicillin & procaine penicillin are long acting. 3- penicillin allergy is rare among
notes children and 1-5% of adults are allergic. 4- penicillins can be used prophylactically ( to prevent infections).
