| Abstract | ||
| Porosity and pore structure are important characteristics of pharmaceutical tablets, since they influence the physical properties, such as mechanical strength, density and disintegration time. This paper is an attempt to investigate the pore structure of four different paracetamol tablets based on mercury porosimetry. The intrusion volumes of mercury were used to calculate the pore diameter, pore volume and pore size distribution. The result obtained indicate that the variation of the pore volume in the tablets followed the sequence:- S.D.I. Iraq Pharmacare,Dubai-U.A.E. Bron and Burk(UK) LondonLark Laboratories(India), while the variation of surface area followed the sequence:- S.D.I. Iraq Lark Laboratories(India) Pharmacare,Dubai-U.A.E. Bron and Burk(UK) London | ||
