Modified-release dosage is a mechanism that in contrast to immediate-release dosage delivers a drug with a delay after its administration delayed-release dosage or for a prolonged period of time extended-release [ER, XR, XL] dosage or to a specific target in the body targeted-release dosage. Sustained-release dosage forms are dosage forms designed to release liberate a drug at a predetermined rate in order to maintain a constant drug concentration for a specific period of time with minimum side effects.

This study is based on the QbD development of extended-release ER extruded-spheronized pellets of Meclizine HCl and its comparative pharmacokinetic evaluation with immediate-release IR pellets. HPLC-fluorescence method was developed and validated for plasma drug analysis. The C max of IR pellets

Conventional drug delivery system for treating the angina and hypertension are not much effective as the drug do not reach the site of action in appropriate amounts. Thus potent and guarded therapy of this angina and hypertension disorder using specific drug delivery system is a challenging task to the pharmaceutical professionals. Most oftenly used method of regulating the drug release is to include it in a matrix system because of their pliability, hydrophilic polymer matrices are widely used in oral controlled drug delivery to obtain a desirable drug release pattern, methodical, and broad regulatory compliance. Formulation of Nifedipine sustained release matrix tablet was prepared by the polymers blend with to get desirable drug release profile. Evaluation parameters of formulated tablets were hardness, friability, thickness, drug content uniformity weight variation, and the in vitro drug release rate pattern.

Modified-release dosage

Show all documents For first 2 h tablet was placed in 1. At specified intervals 5 ml samples were withdrawn from the dissolution medium and replaced with fresh medium to keep the volume constant. The absorbance of the sample solution was analyzed at nm for the presence of model drug, using a UV-visible spectrophotometer. Results are shown in Table 4.

The release characteristics of Diltiazem HCl from matrix tablets were determined according to the official method using a six station USP Apparatus-II at rpm .

The purpose of this study was to develop a bilayer floating drug delivery system of Diltiazem Hydrochloride DTZ. Floating drug delivery systems can remain in the gastric region for several hours and therefore prolong the astric residence time of drugs and improve drug bioavailability. In this study novel bilayer formulation of floating tablet comprising drug contained core and floated outer layer was prepared.
