Man, that's creepy. Especially if you think about Captain Cephalosporin Kirk that goes after every bug princess in the galaxy. "Hey bacteria babe, how you doing?"
Contrary to popular belief, I'm not a huge Star Trek fan. If a pointy eared guy comes up to me, with a psycho split-fingered sign, saying, "Live long and prosper," I'd mace him and run screaming. Then I'd feel bad and give him the card of a plastic surgeon friend of mine. Because somebody has to do something about those ears.
Anyway, back to the message at hand: Second-generation Cephalosporins.
Cefuroxime: Also called Ceftin and Zinacef, Cefuroxime has more coverage of H. influenzae, Enterobacter and Proteus than Cefazolin.
Cefuroxime is administered largely via IV and has a stable shelf-life. It is approved for H. influenzae meningitis which is unresponsive to other medications. It is preferred in ampicillin-resitant strains of H. infleunzae. In addition to that it is highly active against Moraxella catarrhalis, which is a common cause of otitis media, sinusitis, cholecystitis, gonorrhea, lyme disease, tonsilitis, bronchitis, and pneumonia in patients with underlying chronic lung conditions.
Normal Adult Dosage: 500 to 750 mg by IV per every 8 hours. Treatment is usually finished up with oral dosing of 250 to 500 mg every 12 hours.
Child Dosage: It can be used in children older than 3 months. Orally 30 mg per kg per day with a maximum of 1 gram per day. IV dosing is 75 to 150 mg per kg per day with a max dose of 6 grams per day.
Cefoxitin and Cefotetan: The Cephamycin twins. These Cephalosporin twins are known for their activity against Bacteroides, E. coli, P. mirabilis, and Klebsiella. The twins are emotionally stable and take on seriously mutated beasts together.
Yet, Cefotetan lives longer than it's twin. Cefotetan has a longer half-life than Cefoxitin, making its dosing less frequent. It is also more active than Cefoxitin, because the foxy one is spending too much time at clubs.
These two drugs treat infections of the womb (amnionitis and endomyometritis), aspiration pneumonia (pneumonia caused by vomit entering the trachea), human bites (now this is a good one when the Zombies come ;) ), eye cellulitis, community-acquired pneumonia, liver abscess, pelvic inflammatory disease, and surgery prophylaxis.
Normal Adult Dosage:
Both drugs are only administered by IV or IM. 1 to 2 grams every 6 hours. If given by IM, a Cefoxitin injection is painful, but the dosing is the same as IV. Can be given up to 12 grams per day.
The twins can be given to children older than 3 months of age. 80 to 100 mg per kg per day divided into 8 doses to be given every 4 hours. Cefotetan has a maximum of 6 gram per day.
Cefaclor: Brand name Raniclor, this antibiotic is great for otitis media and pharyngitis. There isn't a lot to say about this drug. It likes to keep to itself.
Normal Adult Dosage: 250 to 500 mg by mouth per every 8 hours. If renal impairment then give 50% of the usual dosage, unless the kidney problems are severe in which case you would administer approximately 25% of the usual dose.
Child Dosage: 20 to 40 mg per kg weight of child per day divided into 3 doses, to be given every eight hours. For a maximum of 2 grams per day.
WARNING: This drug can cause a severe condition called Sick Serum Syndrome which can lead to death. Another reason why it likes to keep to itself: it's trapped in self-loathing.
Well, that's it for the second generation.
