However, tablet binder is one of the most essential excipients for tablet manufacturing. We know that the tablet is one of the most used and preferred dosage forms. Hypromellose/ hydroxypropyl methylcellulose (HPMC), Methocelĭepending on MW (molecular weight) of PEG, it is also known as polyethylene oxide (PEO) or polyoxyethylene (POE).ģ–20% w/w (usually 5–10%, depending on the starch type) as a binder for wet granulationĥ–20 as dry binder in tablet formulations List of Tablet Binder used in Pharmaceutical Preparations Name of Tablet BinderĬalcium carboxymethylcellulose calcium cellulose glycolate carmellosum calcium Ĭarboxymethylcellulose Sodium, Carmellose SodiumĮthylcellulose being blended dry or wet granulated with a solvent such as ethanol (95%). In addition, the binder ensures the tablet shape remains unbroken after compression. Thus, a binder is added either dry or in liquid form during wet granulation to form granules or to promote cohesive compacts for directly compressed tablets. Certainly, during compression particles need to compact and this is possible when one or more binders used in a formulation. Compressibility is required for the proper compress of tablets.Ī binder can accumulate fine particles to large particles (granules) and these large particles have adequate flow properties and compressibility. Secondly, Proper Compressibility: Particles of powder or granules of the tablet should have proper compressibility. Why Tablet Binder is necessary for Granulation?ĭuring compression fine particles of power (both active and inactive ingredient) or granules must have two properties:įirstly, Proper Flow property: Fine particles have fewer flow properties and thus, they make problems such as weight variation, segregation of powder particles during manufacturing. ![]() ![]() ![]() Examples of Solution tablet binders include cellulose, gelatin, cellulose derivatives, polyvinyl pyrrolidone, starch, sucrose, mannitol, polyethylene glycol, and liquid glucose, etc. These are dissolved in a different solvent such as water or isopropyl alcohol. Solution tablet binders: These are used in wet granulation processes. Examples of Dry tablet binders include cellulose, Polyvinyl Pyrrolidone (PVP), Hydroxy Propyl Methyl Cellulose (HPMC), Sodium CarboxyMethyl Cellulose, Polyethylene Glycol (PEG), and Methyl Cellulose. Image of Carboxymethyl Cellulose Based on their application in the manufacturing process:ĭry tablet binders : These are added to the powder blend, either after a wet granulation step or as part of a direct compression (DC) formula. Saccharides and their derivatives: Disaccharides such as lactose and sucrose Polysaccharides and their derivatives such as starches, cellulose or modified cellulose such as MCC and cellulose ethers such as hydroxypropyl cellulose (HPC) Sugar derivatives such as sorbitol, xylitol, and mannitol, etc.Examples include Polyvinyl Pyrrolidone (PVP), Methylcellulose, Hydroxy Propyl Methyl Cellulose (HPMC), Polymethacrylates, Sodium Carboxy Methyl Cellulose, Polyethylene Glycol (PEG) and Methylcellulose, etc. Synthetic/ Semisynthetic: These are the most widely used and required a low amount in a formulation.Examples include starch, pregelatinized starch, Sodium alginate, and gelatin, etc. Natural: These are less toxicity, biodegradable, availability at low cost.List of Tablet Binder used in Pharmaceutical Preparations Ĭlassification of Tablet Binder Based on their source:.Why Tablet Binder is necessary for Granulation?.Based on their application in the manufacturing process:.
