)We have an ampicillin product for reconstitution. It contains 2.5 g of ampicillin to be made up to 100 mL. To what volume should it be made to give 100 mg per 5 mL dose?
Thank you so much for creating these videos . Please could you kindly link reconstitution solutions(if available ) where the powder volume does not contribute to the final volume .
Thank you for the comment. In situations when the powder volume does not contribute to the final volume, then the final volume will be the same as the volume of diluent added and all pertinent calculations will be based on the volume of the diluent. Hope this helps.
Hello Dr. Danquah. Great Job! Can you help with this problem? A female patient weighs 79 kg, and Amoxicillin 4 mg/Kg IV administered over 30 mins is ordered once every 24 hrs for 10 days. Amoxicillin powder for injection is available in 250 mg vials. The 250 mg vial is diluted with 5 ml 0.9% NaCl. If the patient's dose is diluted in 50 ml of 0.9% NaCl, what is the administration rate in ml/hr? Thanks, v m.

Hi can you help with this question? (board exam on tuesday) The label of a dry powder for oral suspension states that when 111 mL of water are added to the powder, 150 mL of a suspension containing 250mg/5mL ampicillin are prepared. How many ml of water should be used to prepare a suspension which would contain a dose of 8 mg/kg per 5 mL. to be given to a child weighing 60 lbs using same total amount of drug as of 150 ml of 250mg/5ml suspension. I have an answer but id like to know if i did it right

@@PharmaceuticalCalculationsEasy do you have time for one more question ? You've 20 ml ampoule of a conc. 0.75 %, if you need to prepare 250 ml solution have conc. of 0.125 % so what is the volume of diluent needed to dilute soln.? I tried the fv=dv+pv method but my answer is completely different from what is on my document. can you help me with this one ?
Thank you so much Dr! May I ask this question regarding reconstitution of oral preparations: 'The label of a dry powder for constitution into pediatric drops states that when 12 mL o f purifed water is added to the powder, 15 mL of a pediatric suspension containing 50 mg of amoxicillin per milliliter results. How many milliliters of water should be added to prepare the dose of amoxicillin in each 10 drops if the dropper delivers 20 drops/mL, the child has a body surface area (BSA) of 0.4 m2, and the dose of the drug is based on 50 mg/m2 of BSA?'

@@henrysourial3328 Here are the step-by-step solutions: jo.my/ourpwf (algebraic method) and jo.my/xwbrrm (alligation method). Regarding the ampoule(s), the amount of api needed to make the 250 mL will require more than one ampoule. Hope this helps.
a bottle of PCN powder contains 20,000 units of penicillin.when reconstituted with 25.3 ml sterile water for injection, it produces 500,000 units/ml. How many milliliters of sterile water for injection should be added to the bottle to provide 1,000,000 units per ml? Thanks.

Thank you for watching and for the comment. Below is the solution.
(225mg/1 mL) = (250mg/X mL)
X = ((1 mL x 250 mg)/225 mg) = 1.11 mL
Thank you. Got the same answer too
