The aim of the present study was to prepare unidirectional buccal films of buspirone hydrochloride by solvent casting technique. Hydroxypropylmethylcellulose (HPMC K15M) and Eudragit RL-100 were used as polymers in different proportion. Polyethylene glycol 400 and sodium lauryl sulphate were used as plasticizer and permeation enhancer, respectively, in different concentration. In the formulatio...
The vaginal route of administration is an alternative for several treatments for either local or systemic pharmacological effects. However, the permanence of a drug in this route represents a challenge for formulation development that can be overcome by using nanoencapsulation and chitosan gel. Thus, this work aimed to evaluate the performance of chitosan hydrogels containing cationic and anion...
the objective of the present study was to prepare controlled release formulation of moxifloxacin hydrochloride ocular nanoparticles. the nanoparticles were prepared by solvent displacement method using eudragit rl 100 as a polymer. different formulations were prepared by varying the ratios of drug and polymer and varying the ratios of organic and aqueous phase. the formulations were evaluated i...
rivastigmine hydrogen tartrate (rht), one of the potential cholinesterase inhibitors, has received great attention as a new drug candidate for the treatment of alzheimer's disease. however, the bioavailability of rht from the conventional pharmaceutical forms is low because of the presence of the blood brain barrier. the main aim of the present study was to prepare positively charged eudragit r...
BACKGROUND Owing to its short half-life and lack of oral absorption, heparin has to be administered by the parenteral route. An oral heparin formulation, however, would avoid the disadvantages of parenteral injections and would consequently be highly desirable for patients. Polymeric nanoparticles (NPs) prepared with biodegradable poly-epsilon-caprolactone (PCL) and poly(lactic-co-glycolic acid...
A novel two-step release system for the traditional Chinese medicine compound Danshen was developed by combining an effervescent osmotic pump tablet (EOPT) and a pulsed-released tablet (PT) of compound Danshen into one hard capsule. The EOPT of Danshen was prepared with sodium chloride, mannitol, hydroxypropylmethylcellulose (HPMC), and sodium bicarbonate as osmotic agents. The osmotic pressure...
Evaluation of the Mechanical Properties and Drug Permeability of Chitosan/Eudragit RL Composite Film
the purpose of this study was to develop a new monolithic matrix tablet to completely deliver glipizide in a zero order manner over a sustained period. two approaches were examined using drug in a formulation that contain polymer like hydroxylpropyl methyl-cellulose k 100 (hpmck) and eudragit l 100. the granules were prepared by wet granulation method and thereby formulated as f-1, f-2. f-3 and...

Floating multi-layer coated tablets were designed based on gas formation. The system consists of a drug-containing core tablet coated with a protective layer (hydroxypropyl methylcellulose), a gas forming layer (sodium bicarbonate) and a gas-entrapped membrane, respectively. The mechanical properties of acrylic polymers (Eudragit RL 30D, RS 30D, NE 30D) and ethylcellulose were characterized by ...
