Colin who is 78 years old has been admitted to a ward where you are working, with acute bacterial meningitis. The duty doctor wants to treat with meropenem and she would like to know what dose to treat with. In Colin’s notes you see that he has a history of kidney injury, you have his weight which is 49kg and his serum creatinine is 157micromol/L.

What is Colin’s estimated creatinine clearance?

2. What is the maximum daily dose (in grams) of meropenem that Colin will receive?
