Drug to Polymer Ratios of Formulations Investigated in This Study^{*, **}

S. No	Formulation code	ZD (g)	Polymer content (g)		Eudragit S 100 (g)
			PVP	HPMC
1	SDZDPS	1.0	7.2	-	1.8
2	SDZDHS	1.0	-	7.2	1.8
3	SDZDHS-M	1.0	-	7.1	1.9
4	SDZDHS-Z	1.0	-	7.0	2.0

^*The formulated solid dispersions codes were constructed in a manner to better elucidate their constituents. For example, in ‘SDZDPS’ or ‘SDZDHS’, SD represents solid dispersions, while (ZDPS or ZDHS) represents solid dispersion constituents of gefitinib (ZD), PVP, Eudragit S 100 for ZDPS; and gefitinib (ZD), HPMC, Eudragit S 100 for ZDHS

^**M or Z indicates the polymer content for HPMC and Eudragit S 100 in the dispersions (as shown in the above table)
