A binding agent for tablets is essential when it comes to producing pills. As most know, a binder is an ingredient used to manufacture solid dosage forms such as tablets and capsules. It’s purpose is to hold together the individual components of a pill, creating a cohesive product that can withstand handling and storage processes during production and distribution. With so many types of binders available today, choosing the right one for your application can be overwhelming. Here are some of the best binders to use when producing your pills:


One of the most commonly used binders in pharmaceutical manufacturing is povidone (also known as polyvinylpyrrolidone), which helps ensure proper tablet formation and hardness during processing. Povidone also offers superior adhesion properties compared to other binders, making it ideal for applications where uniformity and accuracy are important factors. Additionally, povidone has excellent compressibility qualities, allowing for easy compression when forming tablets or pellets.

Cellulose Derivatives

Cellulose derivatives such as microcrystalline cellulose (MCC) are another type of binder found in many pill formulations due to their ability to provide both strength and flexibility during compression processes. These cellulose-based materials offer good flowability characteristics, meaning they can easily disperse throughout a formulation without clumping or clogging equipment parts during manufacturing operations. They also help reduce dusting levels while promoting excellent tablet integrity over time.

Starch based compounds

Starch-based compounds are often chosen as suitable binders due to their low cost and availability on the market today. Starch offers good adhesion and strong disintegration properties – making it particularly suitable for capsule-filling machines – while providing exceptional resistance to moisture absorption over time. Starch derivatives such as pregelatinised starch are desirable choices as these additives have excellent thermal stability properties; they don’t change shape or form even under extreme temperatures or pressures during production cycles.

Polyethylene glycols (PEGs)

Polyethylene glycol (PEG) compounds are gaining traction among pharmaceutical manufacturers for their ability to produce hard yet flexible tablets with superior stability profiles over time – allowing them to remain intact until consumed by patients or consumers. PEG compounds also provide better drug delivery systems compared to other traditional excipients currently used throughout the industry due to their ability to form cohesive blends with active ingredients in wet granulation processes without compromising shelf life or efficacy rates over long periods of time.

Hydroxypropyl Methylcelluloses (HPMC)

Hydroxypropylmethylcelluloses (HPMCs) have recently become a popular alternative for tablet manufacturers because they offer a number of advantages not seen with other common binders today – such as improved dissolution profiles and greater compatibility with water-soluble drugs than MCCs alone can provide. These cellulosic materials offer enhanced mechanical strength when compressed into solid tablets, and HPMCs act as a protective coating against temperature fluctuations – protecting product contents from rapid degradation in hot climates. Finally, HPMC’s flexibility allows it to be extruded into various shapes without compromising quality.

Magnesium silicates

Magnesium silicates have recently come to the fore due to their unique combination of lubricating properties and high durability with improved tensile strength over time, making them the perfect choice for high-volume, high-speed production. Magnesium silicates offer good flow characteristics but lack good adhesion, so additional binder(s) should always be added to achieve the desired results in automatic filling machines.


The choice of an ideal binder for tablets depends largely on several factors, including the desired post-production outcome, compatibility rates between ingredients within formulations, budget constraints, etc. Therefore, in-depth research may be required before selecting a particular type, but if done correctly, you should ultimately be able to find an optimal solution that meets all your needs accordingly.
