Class II and IV drug on the Biopharmaceutical Classification System are those with the commonest solubility issues. The objective of this work is to study the effect of the use of cyclodextrin combined with each PVP, and PEG 6000 individually, then combined, and the enhancement of solubility and dissolution rate on three BCS class II celecoxib and Valsartan, and Class IV Furosemide.
A serie of
Solubility levels of the three studied drugs was highly enhanced by the studied excipients. The highest solubility improvement was recorded for the combination of βCD with PEG 6000 (4,95ratio) IN THE CASE OF Celecoxib, and forβ-CD in combination with PEG 6000 and PVP (25,52 ratio) in the case of FSD, then in the combination of βCD with PEG 6000 (21, 41ratio) in the case of Valsartan. The highest enhancement of celecoxib dissolution rates was recorded for CCX-βCD (1:2) - PEG 6000 (2%) combination (10,03 ratio), for FSD- βCD (1:2)-PEG 6000 (2%)-PVP (2%) combination (22,61 ratio) in the case of furosemide and for VST-PVP (2%) combination (3,54ratio) in the case of Valsartan.
PEG 6000 is a suitable solubilizer alone and in combination with βCD and PVP to enhance the solubility and dissolution rate of the selected three BCS Class II and IV drugs.
