Kpharma Posted June 30, 2008 Share Posted June 30, 2008 A prescription for alomide reads as follows Alomide 0.1 % eye drops Sig: 2 gtts ou qid X 30 days How many milligrams of alomide are present in per day dose of the drug? I thought per day 16 drops. 1ml =20 drops ? 16 drops so it would be 0.8 ml drug is 0.1% 100-------------0.1 0.8-------------? So I got the answer as 0.8 mg But the answer given in the book is 1.6 mg. Please correct me If I am wrong? Thank you Kpharma Quote Link to comment Share on other sites More sharing options...
Nicli Posted July 3, 2008 Share Posted July 3, 2008 I tried that calculation, and I came up with 0.8mg/day as well. the only possible way I can think of getting 1.6 is if they thought there were 10 drops/mL, but that does not make any sense. Is it possible that the book is wrong? Quote Link to comment Share on other sites More sharing options...
bva Posted July 15, 2008 Share Posted July 15, 2008 Where is the 20 drops/ml coming from? I thought it is 25 drops/ml. Anyway, I did not have 1.6 mg. Quote Link to comment Share on other sites More sharing options...
fafy Posted July 31, 2008 Share Posted July 31, 2008 It is because you are giving drops in both eyes so 0.8x2. By the way, where are you studying the calculations from? I am trying to use APHA but it is such a mess, I'm lost! Particularly the beginning of the chapter about kinetics. Can you answer me please?

lol5561 Posted August 2, 2008 Share Posted August 2, 2008 Hi, I don't think you can again multiply it by 2, because 16 drops is for both the eyes. Please correct me if I am wrong. Quote Link to comment Share on other sites More sharing options...

I Agree with LOl. if you typed the problem correct it should be 0.8 and elieve me some times the answers are wrong, thats why they some up with new ed. to the book :P Quote Link to comment Share on other sites More sharing options...
