Investigation of Plantago ovata Husk as Pharmaceutical Excipient for Solid Dosage Form (Orodispersible Tablets)

Table 2

Pharmaceutical characterization of PO husk.

Parameter (unit)	Result
Bulk density (g/mL)	()
Tapped density (g/mL)	()
Carr’s index	12.41
Hausner ratio	1.13
Angle of repose (°)	0.00
Flowability (sec)	0.00
Swelling index (unprocessed) (%)	()
Swelling index (powdered) (%)	()
Interparticle porosity	0.499
Loss on drying (%)	()
Compressibility	0.00

Note: results are presented as (); time taken by 100 g husk to flow through an orifice; parameter has no unit because it is the ratio between two parameters with same units; powder was unable to flow and hence the parameter was unable to be determined.
