Evaluation of spherical crystallization as particle size enlargement technique for Aspirin. The strength of agglomerates is determined by interfacial tension between bridging liquid and continuous phase, contact angle and ratio of volume of bridging liquid and solid particles. Development of spherical crystals of acetyl salicylic acid for direct tablet making. Evaluation parameters for spherical agglomerates:- Flow Property :- Flow property of the material depends on the force developed between the particle, particle size, particle size distribution, particle shape, surface texture or roughness and surface area. PD Techno. Keywords Aceclofenac spherical agglomerate solubility dissolution micromeritic properties. E2 AND E3 could be calculated from the force displacement curve. This Technique involves simultaneous crystallization and agglomeration of two or more drugs from good solvent and bridging liquid by addition of non- solvent.
Pak J Pharm Sci. Jul;20(3) Improved bioavailability of aceclofenac from spherical agglomerates: development, in vitro and preclinical studies.
Aceclofenac agglomerates were prepared by spherical crystallization technique using a three solvent system comprising acetone: dichloromethane (DCM).
Spherical Agglomeration Techniques and their Evaluation Parameters Insight Medical Publishing
The spherical agglomerates contained an aceclofenac-paracetamol ratio in the range of to The result revealed that micromeritic.
The Theory and Practice of Industrial Pharmacy. This article gives a detailed and comprehensive review about different techniques, its advantages, mechanism and application of Spherical agglomeration Technique along with its Evaluation and Characterization methods.
The Extent of Mechanical agitation in conjugation with amount of bridging liquid determines the rate of formation of agglomerates and its final size. This technique has been successfully utilized for improvement of flowability and Compressibility of crystalline drugs.
Flowability of the agglomerates is much improved as the agglomerate exhibits lower angle of repose then that of single crystals.

|Shivakumar, Particle design of Enoxacin by spherical crystallization technique II, Characteristics of agglomerated crystals.
Temperature has significant role to play and has great influence on final shape, size and texture of agglomerates. Tablets containing sparingly soluble water soluble drugs, the start of dissolution is often delayed by poor wettability of the tablet surface and slow penetration into tablet matrix.
Mode and Intensity of Agitation:- The Extent of Mechanical agitation in conjugation with amount of bridging liquid determines the rate of formation of agglomerates and its final size. Spherical crystallization: direct spherical agglomeration of Salicylic acid crystals during crystallization.
The aim of present study was to improve dissolution rate and micromeritic properties of aceclofenac by spherical agglomeration techniques. The spherical. Spherical crystallization techniques are the promising techniques in which the drug crystals are modified . aceclofenac spherical agglomerates.
