Answer #1

Weight of the patient is 90kg

Average steady state concentration(desired peak concentration of drug ) C​​​​​​p = 5mg/L

Bioavailability (F) of the drug is 86%

Clearance is 0.08 L/hr/kg

Calculate the maintenance dose :

Formula : MD = C​​​​​​p​​​​​C​L/ F

= 5mg/L × 0.08L/hr/kg ÷ 86

= 5 mg × 0.08 /hr /kg ÷ 86

= 0.0046 mg /hr/kg
