Microencapsulation is one of the novel methods for retarding drug release from dosage forms and minimizing the adverse effects thereby increasing the patient compliance. Microspheres form homogeneous, monolithic particles which improve the treatment by providing localization of the drug at the site of action and by prolonging the drug release. The objective of the present study was to formulate...

The objective of this investigation was to develop the hollow microspheres as a new dosage form of floating drug delivery system with prolonged stomach retention time. Hollow microspheres containing ranitidine hydrochloride were prepared by solvent evaporation method using Eudragit RLPO dissolved in a mixture of dichloromethane and ethanol. The maximum yield and drug loading amount of hollow mi...

BACKGROUND Microencapsulation is a useful method to prolong a drug release from dosage forms and to reduce its adverse effect (1) among various available methods. The microencapsulation of hydrophilic active ingredients requires the use of a polar dispersing phase such as a mineral oil. Acetone/paraffin systems are conventionally used. OBJECTIVES The current study aimed to investigate two dif...

Inhalation Ciprofloxacin HCl microspheres were formulated with combination of alginate and kappa carrageenan a total 1% (F1), 1.5% (F2), 2% (F3). Aim this research is to examine effect polymer concentration on characteristics, release, lung deposition microspheres. Microspheres characterized including loading, efficiency, yield, size, moisture content, mucoadhesivity, release. Deposition was st...

Porous polydivinyl benzene (PDVB) microspheres of narrow size distribution were formed by a single-step swelling process of template uniform polystyrene microspheres with divinyl benzene (DVB), followed by polymerization of the DVB within the swollen template microspheres. The PDVB porous particles were then formed by dissolution of the template polystyrene polymer. Unique "cauliflower-like" Zn...
