Abstract:
The purpose of this study was to evaluate the effect of changing dimensions on the hardness (H), disintegration time (DT), and wetting time (WT) of fast-disintegrating epinephrine tablets for sublingual administration as potential first aid treatment for anaphylaxis. Tablet formulations I and II, containing 0% and 10% epinephrine bitartrate, respectively, and weighing 150 mg were prepared by direct compression. Formulations were compressed at a range of forces using an 8/32'' die with concave punches (CP); a 10/32'' and an 11/32'' die with CP and flat punches (FP). Tablet weight variation, content uniformity, thickness, H, DT, and WT were measured. The 8/32'', 10/32'', and 11/32'' dies resulted in tablet thickness of ranges 0.25-0.19'', 0.17-0.1'', and 0.16-0.08'', respectively. The DT and WT using the 8/32'' die were
