Acetaminophen is well known pain reliver (it is an active ingredient in brand such as Tylenol).

Active drug is processed to make a D.C. grade and a coated grade of materials. 525 mg of D.C. material has 500 mg Active (formulation I and II); and 566 mg of Coated material has 500 mg of active (formulation III and IV).  This relates to 700 mg total weight of tablet. These two materials are used to develop formulation.

The properties are compared to crystalline powder, see the following Data.

Ingredients	Mean particle sizeμ	Bulk density (g/ml)	Tapped Density g/ml		Angle of repose
Acetaminophen Crystal	>355	0.382		0.259	Not done
Acetaminophen D.C.	>45	0.679		0.530	41.63
Acetaminophen coated	>250	0.469		0.417	39.52

The following Formulations compositions, % W/W, are studied.  Brand names of some excipients are also listed. Please do own research about these ingredients and other info.

Question:  Please answer those questions from the data!!!

1. Write manufacturing procedure(s) in sufficient detail (not one liner) for 100 kg batch. Score 3
2. Provide equipment used in the process, explain equipment capacity, describe operating conditions, including size of tablet for 500 mg dose.  Score 3
3. Show (Draw) the Compaction profiles, i.e., Pressure vs Time for formulation during the pressing of powder for formulation of ONE formulation you concluded is the best. (If you give two or more formulations, then you will get 0) for entire test). 

Explain why did you the formulation is the best? Include several tables with analysis of data (tables and graphs) in your answers (Score 0 for only words).  Score 6
