Mucoadhesive buccal film is developed as a promising dosage form, which has prominent advantages because of drug delivery through buccal mucosa. New formulation of buccal films containing rizatriptan benzoate (RB) was prepared by solvent casting method using various concentrations of hydroxypropyl methylcellulose (HPMC K4M), polyvinyl alcohol (PVA), polyethylene oxide (PEO), glycerol, stevia, a...

The study was aimed to design and evaluate a new effervescent mucoadhesive vaginal drug delivery system for ciclopirox olamine (CPO), a broad-spectrum antifungal, antibacterial, and anti-inflammatory agent for effective treatment in vaginal candidiosis. Various polymers like Polyox 303, Carbopol 974P, HPMC K4M, Sodium CMC, HPC, Sodium Alginate, Xanthan Gum, Polycarbophil and Chitosan were used ...

The aim of this study was to develop a sustained release hydrophilic matrix tablet of Diltiazem HCl and evaluates the effect of formulation variables (e.g. lubricant, binder, polymer content and viscosity grades of HPMC) on drug release. Twelve different formulations (F1-F12) were prepared by direct compression. The results of the physical parameters and assay were found to be within the accept...

buccal mucoadhesive films have attracted great attention among mucoadhesive systems due to their ability to adhere and remain on the oral mucosa and to release their drug content gradually. the aim of the current study was to formulate the ziziphus jujuba aqueous extract as buccal bioadhesive film, which continiously releases the drug at sufficient concentration for reducing the frequency of th...

Object: The objective of the present study was to investigate the effect of various concentrations of natural and synthetic polymers on in vitro drug release from sustained release matrix tablets. Materials and method: HPMC K4M and acacia gum were used as synthetic (hydrophilic) and natural (hydrophobic) polymers respectively. Diclofenac sodium was used as a model drug to study the in vitro rel...

The overall aim of the present study was to widen our knowledge about the biopharmaceutical behaviour of novel hydroxypropyl methylcellulose (HPMC)-based two-piece capsules by comparing them with the classic hard gelatine capsules. Firstly, the tendency of the HPMC capsules to stick to isolated porcine oesophageal preparation was evaluated. The force needed to detach the HPMC capsules from the ...

Venlafaxine Hcl is an anti-depressant drug which is used in depression. The aim of present investigation was to prepare an ER tablet of Venlafaxine Hcl with similar dissolution profile matching to Effexor ER. An immediate release core tablet of 100mg was prepared and it was compression coated using HPMC matrix system. HPMC of three viscosity grades i.e., K4M, K15M, K100M and different concentra...

buccal mucoadhesive systems among novel drug delivery systems have attracted great attention in recent years due to their ability to adhere and remain on the oral mucosa and to release their drug content gradually. buccal mucoadhesive films can improve the drug therapeutic effect by enhancement of drug absorption through oral mucosa increasing the drug bioavailability via reducing the hepatic f...

Abstract Levetiracetam as an Anti-epileptic drug with exclusive mechanism of action is accepted by the USA Food and Drug Administration as an adjunctive therapy in treating epilepsy in young adults. The purpose of this project is the design and formulation of prolonged release of levetiracetam using two types of retarding agent such as Hydroxyl Propyl Methylcellulose (HPMC K4...

Polysaccharide mucilage derived from the seeds of Ocimum basilicum L. (family Lamiaceae) was investigated for use in matrix formulations containing propranolol hydrochloride. Basil mucilage was extracted and several tablets were formulated. The effect of mucilage on drug release rate was evaluated in comparison with tablets containing two kinds of hydroxypropyl methylcellulose (HPMC K4M and HPM...
