Guaifenesin, a highly water-soluble active (50 mg/mL), classified as a BCS class I drug.Owing to its poor flowability and compressibility, formulating tablets especially high-dose one,may be a challenge. Direct compression may not be feasible. Bilayer tablet technology appliedto Mucinex®, endures challenges to deliver a robust formulation. To overcome challengesinvolved in bilayer-tablet manufa...

Bilayer tablets are novel drug delivery systems where combination of two drugs in a single unit having different release profiles can be delivered. improve patient compliance, prolong the drug(s) action and deliver incompatible formulation. have one layer active ingredient for immediate second delayed release, either as dose or an extended fashion. advancing helpful technologies to overcome dis...

The objective of the present investigation was to develop a bilayer-floating tablet (BFT) for captopril using direct compression technology. HPMC, K-grade and effervescent mixture of citric acid and sodium bicarbonate formed the floating layer. The release layer contained captopril and various polymers such as HPMC-K15M, PVP-K30 and Carbopol 934p, alone or in combination with the drug. The floa...

Hypertension, or high blood pressure, is a major public health concern around the world because of its large contribution to global burden and function as risk factor for variety disease processes. Bosentan SR Floating Bilayer Tablets were made with HPMC K4M, E-15, E-15 alone (80%) in combination varying percentages polymer (20&60 percent, 40&40 60&20 percent ). The hydrophilic used...

The present study is to establish bi-layer tablets of Glimepiride and Captopril, of which Glimepiride as immediate release and Captopril as sustained release layers. Immediate release layer was prepared by direct compression method by using cross povidone as disintegrant and sustained release layer was prepared by direct compression method by using HPMC K4 as polymer. Both powder blends of imme...
