megaloporous controlled release tablets of diclofenac sodium (ds) were prepared with two kinds of granules. one of them is the restraining-phase matrix granule (rmg) and it controls the release rate of the drug. the other one is the soluble housing-phase matrix granule (hmg) and controls liquid penetration into the system. carnauba wax and eudragit l 100 polymers were used to constitute the res...
This study was aimed at developing risperidone oral disintegrating mini-tablets (OD-mini-tablets) as age-appropriate formulations and to assess their suitability for infants and pediatric use. An experimental Box-Behnken design was applied to assure high quality of the OD-mini-tablets and reduce product variability. The design was employed to understand the influence of the critical excipient c...
This study investigated the effect of manufacturing process variables mini-tablets, in particular, concerning fluidized bed granulation on tablet weight variation. Test granules were produced with different conditions according to a definitive screening design (DSD). The five evaluated factors assigned DSD were: grinding speed sample mill at active pharmaceutical ingredient (X1), microcrystalli...
Owing to broad advantages like self-medication, unit dosage form, and patient compliance, cost effective, limited interaction with the excipients possibility of mask unpleasant taste, capsules are most extensively recognized conventional solid form after Tablet. In world Novel drug delivery system overcome disadvantages modifications made in capsule develop a product higher selectivity for medi...
The aim of this study was to evaluate whether the use of enamel matrix proteins with or without the use of deproteinized bovine bone influences bone formation when used as an adjunct to guided bone regeneration (GBR). Twenty rats, divided into four groups of five animals each, were used in this study. Group A1: A hemispherical PTFE capsule was placed empty on the lateral aspect of the mandibula...
Safe and effective paediatric pharmacotherapy requires careful evaluation of the type of drug substance, the necessary dose and the age-appropriateness of the formulation. Generally, the younger the child, the more the attention that is required. For decades, there has been a general lack of (authorised) formulations that children are able to and willing to take. Moreover, little was known on t...
Purpose: Venlafaxine hydrochloride sustained release formulation increases patient compliance by reducing frequency of administration and it also reduces side effects like nausea and vomiting. Hence the objective of present investigation was to develop triple layer sustained release tablets of venlafaxine HCl using xanthan gum or polyethylene oxide. Methods: The venlafaxine HCl 150 mg sustained...
Collagen is regarded as one of the most useful biomaterials. The excellent biocompatibility and safety due to its biological characteristics, such as biodegradability and weak antigenecity, made collagen the primary resource in medical applications. The main applications of collagen as drug delivery systems are collagen shields in ophthalmology, sponges for burns/wounds, mini-pellets and tablet...
The aim of this work was to develop a pulsatile release system with metoprolol for chronotherapeutical use by coating swellable mini-tablets with Eudragit RS. To study the influence of the formulation factors (amount of coating polymer, plasticizer percentage in film coating and swelling agent percentage in mini-tablets), a Box-Behnken design of experiment (DoE) was used. To evaluate the influe...
Purpose: Triple solid dispersion adsorbates (TSDads) and spherical agglomerates (SA) present new techniques that extensively enhance dissolution of poorly soluble drugs. The aim of the present study is to hasten the onset of hypoglycemic effect of glimepiride through enhancing its rate of release from tablet formulation prepared from either technique. Methods: Drug release from TSDads or SA tab...
