Pharmacy Practice Practical : Making Internal & External Solution

The first time ever making internal and external solution myself :O super excited and super panic too.
First, we have to check whether there is any error in the given prescription then correct it and let our lecturer to verify it. Later, we have to search for the formulation of the drug from BPC then calculate how much we needed to prepare our own solution. Then, we have to write out the procedure and write a proper label before starting to make the following solution. What to pay attention like : external solution has to write with red ink and states that "for external use only" while internal solution writes in black ink. Of course we have to weigh and measure our ingredients appropriately as well as calibrate the apparatus. We have to know the formulation to calculate before we can proceed to the next steps. It is really challenging and fun too :) Looking forward for the coming practical :) Super excited and panic still >< hahahaha. Fighting!!!
