example: calculate the first month on ozempic, then the second month, then all subsequent months
DRUG HALF-LIFE (days) = 7
DOSE EVERY (days) = 7
INITIAL CONCENTRATION (mg) = 0
DOSE (mg) = 0.25
NUMBER OF DOSES = 4
continue with the second month where we increase the dose to 0.5mg, but we also have a remaining concentration in the blood which is 0.234375 (the first number of the last line of the previous results)
DRUG HALF-LIFE (days) = 7
DOSE EVERY (days) = 7
INITIAL CONCENTRATION (mg) = 0.234375
DOSE (mg) = 0.5
NUMBER OF DOSES = 4
continue with the third and subsequent months where we stabilize the dose to 1mg, but we also have a remaining concentration in the blood which is 0.4833984375 (the first number of the last line of the previous results)
DRUG HALF-LIFE (days) = 7
DOSE EVERY (days) = 7
INITIAL CONCENTRATION (mg) = 0.4833984375
DOSE (mg) = 1
NUMBER OF DOSES = 100
NOTICE that after a number of dosages the plasma concentration starts to stabilize to a specific range: 4mg after the dose is injected and 2mg at the end of the week
NOTES
MAKE SURE TO USE THE SAME UNITS. FOR EXAMPLE IF THE TIME UNIT IS DAYS, THEN WE MUST USE DAYS AS THE TIME UNIT FOR BOTH THE DRUG HALF-LIFE AND DOSE EVERY FIELDS. THE SAME APPLIES TO VOLUME OR MASS UNIT.
