you need to calcukate a maintenance dose in mg for oatient (90kg) to target an average steady state concentration of 5mg/l. the dose will be administered orally every morning. the oral bioavailibty of this drug is 86% and clearance is 0.08 L/hr/kg

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

    Azithromycin is sometimes prescribed for community acquired pneumonia as 500 mg PO on day 1 then 250 mg PO on days 2-5. You are asked to evaluate the possible maximal lung concentration of azithromycin after the final dose according to these dosing instructions in a male patient who weighs 158 lb. A report in the literature stated that azithromycin lung concentrations are 1030% of azithromycin blood concentrations. Assume azithromycin has an elimination half-life of 53 hr, an absorption half-life of...

    A drug that fully saturates the intestinal transporters required for its absorption necessitates 2.5 hours to be completely absorbed after administering a 100mg dose orally to a volunteer. Once absorbed, the drug has rapid distribution in the body. A 50 mg dose of the drug administered by IV bolus to the same volunteer (in a separate research session) results in plasma concentrations of 1800 ug/L at time 0 hr and 1150 ug/L at time 3.0 hr. If a patient with...
