Half life refers to the concentration of a drug reduced exactly half to the actual strength.
Here the drug has a half life of 12 hours ,it means at 12th hour the dose of the drug will be only 50% of the initial dose.
When the first dose is given at 8am (10mg) by 8 pm it will be reaching its half life ,so the concentration will be 5mg.Again when the 8pm(10mg) dose is administered ,the total drug will be 15mg by 8pm
So in the midnight (usually after 6 hours ) approximately by 2 am the amount of drug in patient body will be 7.5mg (15÷2)

An adult male (73 years old, 65 kg) with diabetes mellitus is placed on hemodialysis. His residual creatinine clearance is <5mL/min. The patient is given tobramycin, an aminoglycoside antibiotic, at a dose, at a dose of 1 mg/kg by IV bolus injection. Tobramycin is 90% excreted unchanged in the urine, is less than 10% to plasma protein, and has elimination half-life 2.2 hours in patient with normal renal function. In this patient, tobramycin has an elimination t1/2 of 50hours during...
