Your patient has severe infection, and you want to get an antibiotic into his system as quickly as possible. you have two choices for your antibiotic, both of which must be injected into muscle and so must diffuse into his blood: penikill'em, which must be stored in the refrigerator and has a molecular weight of 450 g/mol, or azithrolyse'em which is stored at room temperature and has a molecular weight of 200 g/mol. which drug will you chose, and why?

AzithroLyse'Em which is stored at room temperature and has a molecular weight of 200 g/mol

Explanation:

The molecular weight of the antibiotics has a direct correlation with the quickness with which they go to the bloodstream and spread accross the body, so antibiotics with higher molecular weight will take longer to spread and to work in the body, they are slow spreading, this can work when the infection is not as agressive, but at this point the infection is already sever, so we need an antibiotic that is fast, so AzithroLyse´Em will be the best option for a quick effect and to stop the infection from spreading.
