Prolixin is a antipsychotic drug. Dr. is prescribing the drug in liquid form so we will need to figure out how many ml's is 6mg from the sig provided. 4mg = 5ml
{So 7.5ml equals 6mg of the drug} Per dose: 7.5ml
Entire treatment: 22.5ml x 90 days= 2025ml (that is alot of liqiuid medication) Crystal Zamudio, CPhT

The doctor writes a prescription for an insufflation for 500 mg of Amoxicillin for an adult. The active ingredient Amoxicillin is combined with a medium of Calcium Carbonate. There is a 1:3 ratio of Amoxicillin to Calcium Carbonate. The same insufflation needs to be created for an infant; the total weight of the new insuffulation is 300 mg. What is weight of Calcium Carbonate for the new insuffulation and what is the weight of Amoxicillin for the new insuffulation? What is the simple wayto convert 222mcg into ml???

What is weight of Calcium Carbonate for the new insuffulation and what is the weight of Amoxicillin for the new insuffulation? One way is , Let the aamount of amoxicillin be x, then Calcium carbonate is 3x therefore x + 3x = 300 mg 4x = 300 mg
Let me know if this answer is correct. If not i will try with another method.
