This work describes the stability of the selected in situ solutions for ophthalmic delivery of naphazoline hydrochloride ( FF17, FF18) and antazoline phosphate ( GG17 and GG18) based on the pH triggered concept using Carbopol 940 and HPMC K4M. The formulations were evaluated for their pH, isotonicity, gelling capacity, rheological characteristics, in vitro drug release , sterility and in vivo s...

In present study, mucoadhesive vaginal tablet of sertaconazole was designed using a combination of mucoadhesive polymers like Carbopol 934P, chitosan, carboxymethylcellulose sodium, sodium alginate, methyl cellulose, hydroxypropyl methylcellulose and hydroxypropyl cellulose. Effervescent was incorporated into formulations to enhance swellabilty of mucoadhesive tablet. For various drug-free form...

The purpose of present investigation was to develop and optimize bucco mucoadhesive bilayered tablets of Propranolol hydrochloride (PrHCL) using the bioadhesive polymers hydroxyl propyl methyl cellulose (HPMC K4M), xanthan gum (XG) and acrypol 934P (AL-P) individually and in combination along with ethyl cellulose (EC) as an impermeable backing layer. The 3 full factorial design was employed by ...

Floating matrix tablets of norfloxacin were developed to prolong gastric residence time, leading to an increase in drug bioavailability. Tablets were prepared by the wet granulation technique, using polymers such as hydroxypropyl methylcellulose (HPMC K4M, HPMC K100M) and xanthan gum. Tablets were evaluated for their physical characteristics, viz., hardness, thickness, friability, and mass vari...

Venlafaxine is a unique antidepressant that differs structurally from other currently available antidepressants. Short biological half life, low bioavailabilty and frequent administration of drug led rational for development of extended release formulation of Venlafaxine that releases the drug and maintian the plasma drug concentration for more than 12h.Polymers like Hydroxy propyl methyl cellu...

The aim of current study was to explore the influence of three commonly used polymers, that is, cellulosics and noncellulosics, for example, Methocel K4M, Kollidon VA/64, and Soluplus, on the phase disproportionation and drug release profile of carbamazepine-succinic acid (CBZ-SUC) cocrystal at varying drug to polymer ratios (1 : 1 to 1 : 0.25) in matrix tablets. The polymorphic phase dispropor...

The aim of the present study was to prepare and evaluate an osmotically controlled mucoadhesive cup-core (OCMC) containing aceclofenac. A special technique was used while preparing an OCMC. Stability of OCMC was determined in natural human saliva, and it was found that both pH and device are stable in human saliva. OCMC was evaluated by weight uniformity, thickness, hardness, friability, swelli...

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...

This study aimed to produce a gastroretentive floating tablet of Metoprolol succinate and examine the effects release retardant on in vitro drug release. is β1 selective antagonist used as an Anti-hypertensive, Antiarrhythmic, Anti Angina. has 48% oral bioavailability due limited absorption from lower gastrointestinal tract. The tablets were designed increase stomach retention, prolong release,...
