What’s the Critical Micelle Concentration of polymyxin B ?
I believe that this should have been in Homework Help and it stretches the concept of a single Question.
Yes, it is possible to form micelles or there would be no need to know the Critical Micelle Concentration (CMC).

My kitten is on Neomycin and Polymyxin B Sulfate ointment. How long before I should see improvement in eyes?
I started him on the ointment 6 days ago. 3-4 Times a day. His eyes were really green discharge the first day and swollen red, that is why we initially saw the vet. But it seems there is still discharge. ( Not as bad) The first notice of change was the following day. But very minimal change and no change since then. Will it take longer? He is only suppose to be on it 10days and already on it 6. I thought by now there would be more inprovement. The outlines of his eyes are sometimes red and his eyes are always running. I am always removing the discharge and keep his eyes clean with warm water. Should he have another vet visit? She said upper respitory. At the time it was only his eyes. No nasal discharge, or sneezing. Seems this morning he may have tried to cough up some phleme. But appread like it could have been a hair ball. He is 7 weeks old. Thanks for any help.

At this point, if there is no real improvement, I would call the vet and get oral antibiotics. There is usually improvement by the third days if there is going to be. It should be treated before it gets worse.

what is normal dosage and what is it used for?
Neomycin and Polymixin B sulfates are OTC topical antibiotics; hydrocortisone is an OTC antinflammatory. These medications are often found together in cream and/or unguent form. They are used to prevent infection in minor cuts, abrasions, superficial burns, insect bites, etc. They are to be applied to the affected area 2-to-3 times a day; if condition doesn't improve within 5 days or seems to get worse, you should discontinue use and consult a physician.

DEFINATLY NO, AS ERYTHROMYCINE AND NEOMYCIN ARE DRUGS OF SAME GROUP. IF PATIENT IS ALLERGIC TO ONE DRUG THERE ARE HIGH CHANCES THAT HE WILL BE ALLERGIC TO OTHER DRUGS OF SAME CLASS.

LPS-binding antibiotic polymyxin B?
Dear Sir/Madam,
I would be really grateful if you could explain me, what's LPS-binding antibiotic polymyxin B and how it is used while studying the bacterial cells.
Yours faithfully,
Kristina

I'm not exactly sure, but simply judging from the name, it's an antibiotic that binds to LPS (lipopolysaccharide), one of the components in the membrane of Gram-negative bacteria.
According to wikipedia, it is used to alter the chemical structure of the LPS membrane and makes it more permeable to water. The uptake in water kills the Gram-negative cells, but does not kill Gram-positive cells because Gram+ cells have no LPS in their plasma membrane.
I suppose it could be used to separate Gram+ and Gram- bacteria from each other (since it kills Gram- bacteria and not Gram+). It can also be used to lyse Gram- bacteria.

shelf life of neomycin and polymyxin b sulfates and hydrocortisone otic suspension usp?
The actual expiration date should be printed on the bottle. That expiration date is for an unopened bottle. Once the bottle seal has been opened, the contents are no longer sterile and have been exposed to the environment, which over time leads to deterioration and decreased effectiveness.
Each state's pharmacy board determines whether a discard date is required on the prescription label. Most states mandate 1 year (or less). This is an arbitary date although it is based on studies that have shown that regardless of storage conditions most drugs will still be potent after one year. However, this is for the most stable dosage forms, tablets and capsules. Sterile ear or eye drops are less stable once opened and some manufacturers suggest discarding 3 to 6 months after opening.
Hope this helps.

Which diseases are resistant to Cephalosporin, griseofulvin,Bacitracin, and Polymyxin B?
You are asking about antibiotics (cephalosporins, bacitracin, polymyxin B) and antimycotics (griseofulvin). Actually, any germ can develop resistance to any antibiotic treatment. Plus, cephalosporins is a group of antibiotics, with 4 generations and each generation differs in efficacy against bacteria.
can i used neomycin/polymyxin B ear drops in my dogs ears (its a human ear drop)?
my dog has sebborhea (a bacterial infection of the skin). I cant afford the shots anymore, but want to find some way to continue treating my dog at a cheaper price. He was given Cephalexin at the vet (an antiobotic for adults) and Otomax ear drops. I stil lhave cephalexin which works great and will continue using. But Im out of the otomax and was wondering in the neomycin antibotic ear drops could be used in place of the otomax...any help would be appreciated. Especially if anyone could tell me where I could order the cephalaxin and otomax without a prescription
