Welcome to Pharmaceutical Calculations!

This site has been developed by us to make available Pharmaceutical Calculations free to everyone through internet.

Kindly note this site was developed to work best with the then popular internet explorer 5 series. Due to changes in the recent versions of internet explorer, you may face difficulties in utilising this site. .

Some reported it works well with ie6, too. You can download internet explorer 5 series for free anywhere from the net. The following link takes you to one such. Please ascertain yourself about the safety of software and the sites from where you download.

Our search indicated that pharmaceutical calculations are neither available online nor for free.

This site has been developed to make pharmaceutical calculations to be worked out easily by pharmacists, students and by everyone whohave atleast a little idea about pharmaceutical calculations

Your comments and criticism about this site are highly appreciated.

It wouldn't be fair, if we skip to thank our Technical Guru Mr. SAMPATH KUMAR RAJU . It is to his full credit that the calculations transformed from our Visual Basic format to this website.

We also thank the following members for visiting our site and for the encouragement given by them through feedback.

Visitor: , A. N. DESHPANDE @ FEM CARE PHARMA LTD. feedback: Dear Sir, We are one of the leading manufacturers of Pharmaceutical & Cosmetics Products in India and currently working on a speciality cream. We observed that most of the known emulsifiers have failed to give a stable emulsion because the pH is low and the product also contains oxygenating compounds such as Hydrogen Peroxide, Sodium Peroxide, etc. Wonder if you can suggest a suitable emulsifier / an optimum HLB range where one should be working.

Visitor: Lakshmi Narayana K @ feedback: Nice site. I was looking for Lecture Notes and logic of calculations. You see many pharma graduates of Indian Origin appear for the FPGEC/NAPLEX exams in US. There is a heavy dose of Pharmaceutical Calculations in both these exams and later in the practice. A Good Effort. Lakshmi Narayana K.

Visitor: . Maria Glaucia Teixeira Maria Glaucia Teixeira, PhD Associate Professor of Pharmaceutics School of Pharmacy, Laramie, WY feedback: To whom it may concern: I am interested in your site but couldn't get much of what is available in I would like to see how the site handles specific types of calculation used in the pharmacy profession and if it could be of use for our students taking PharmCalc in our school. Thank you.

Visitor: Nate Rickles, Pharm.D., M.S. University of Wisconsin-Madison feedback: Dear Pharmacy Students: Nice work and congratulations for your efforts. I am sure there will be many students who will benefit from this effort. Just a few quick suggestions that might help users of your site. First, please consider adding a table of contents or some guide as to what topics are available on the site. This especially useful for the student or professional not clear as to what topics might be covered by the term "pharmaceutical calculations". Second, in your introduction, you might want to give a little history of how the site came about, how you expect the site to help others and who do you specifically expect to benefit. Third, it is not clear what these med411 awards means. Might you explain the organization, their expertise in critiquing pharm calc information and what the criteria of the award is. I am sure there are many members of the pharmacy community, such as myself, not familiar with this award. Fourth, it is not clear what is a reasonable search strategy using the site. You might want to give examples. For example, I wanted to review pharm calc on anticonvulsants and I typed in "anticonvulsants" and came up with nothing. I think this latter point ties in with the importance of the table of contents or some indicator of the specific content areas of the site. Fifth, what does "clear" and "fuzzy" mean? If you expect your users to use these terms as criteria, then you will need to define them. In sum, I suspect you folks have a little more front end work to do before you let others use your site. Try to make it as "user friendly" as possible. This is not mention to discourage you. The intent of my message is to celebrate your efforts and to help your work more usable for those you want to benefit. :) Good luck my friends.
