Factors to Consider When Selecting Tablet Shapes

A tablet is a small, mobile computing device that can perform a variety of tasks, including web browsing, email, music, video, e-books, and other applications. Its name comes from the Medieval Latin tabuleta and Old French tablete, both of which mean “little box.” The term has also been used in the context of a pill since at least 1580, and in the 1880s, it referred to a pad of paper.

Common ingredients

The composition of tablets depends on the active ingredient. Many medicines contain a combination of excipients, which act to increase the weight of the tablet. A significant amount of weight is better for handling and manufacturing. The quantity of these excipients depends on the active ingredient and other ingredients. Listed below are examples of common excipients used in the production of tablets. The following information explains how each ingredient contributes to the final product.

Binders – Tablets contain various types of binder. Some are dry powders, while others are solutions. The amount of these ingredients plays a critical role in determining the quality and properties of the compressed tablets. Too much binders will make the tablets tough and may cause unnecessary wear and tear on the dies and punches. These binders must be nontoxic and can be obtained from corn starch, acacia gum, hydroxypropyl methylcellulose, polyvinyl pyrrolidone, or a combination of any of these.

Excipients – Other substances used in the preparation of tablets include lubricants, starch, and talc. They protect the tablet from the environment, improve mechanical strength, and mask the taste of the drug substance. Excipients may also help to improve patient acceptance by masking the flavor or enhancing its appearance. Similarly, polymers are used to coat the tablet with a film to increase its mechanical strength and make it easier to swallow.

Excipients – Pharmaceutical companies often add excipients to their tablets to increase their shelf life and improve the patient’s compliance. These components are often referred to as excipients and make up over half of the total mass of the tablet. Though these additives are benign, they are still essential for the proper functioning of a drug product. However, few doctors actually read the label to know what’s inside.


The shape of tablets is an important consideration when developing a tablet manufacturing process. The shape of a tablet may affect the overall efficiency of a production process. While tablets of 8mm in diameter are common, they may not be the most comfortable for patients. Oval-shaped tablets are easier to swallow and have faster transit times. The USA Federal Drug Administration has developed guidelines for tablet shapes. This article will discuss some of the factors to consider when selecting a tablet shape.

First of all, shape matters. Choosing an inappropriate tablet design can lead to problems related to tooling and press wear. Incorrect shapes can also affect packaging and the number of tablets. Also, the wrong shape can lead to duplicated tablet production and packaging. This can be especially problematic if the tablet is a pharmaceutical product. However, a simple tablet shape can often be more cost-effective and result in the highest yield. Therefore, tablet shape and design are crucial factors to consider before making a final decision.

The FDA has suggested that the tablet size should be at least 22 mm to reduce the likelihood of esophageal irritation and decreased compliance. However, this may not be possible for all medications. To avoid this, drug manufacturers can encapsulate bitter-tasting compounds. Therefore, shape may play an important role in improving compliance. Researchers studied the effects of tablet shape on medication compliance by showing participants different photos of seven-colored tablets in various shapes, including a triangular, a hexagonal, and three-sided. A total of 21 tablets were examined.

Tablets also need to be designed for ease of swallowing. The Concave bevel edge, which is often used on round tablets, helps reduce the edge attrition during the coating process. Having a radius-shaped edge helps create a compound cup design, which can help the tablet hold its shape when being compressed. And, the radius-shaped edge also prevents bending at the tip. Lastly, a concave bevel edge has its advantages as well.


How do you measure the size of a tablet? There are a number of ways to measure the size of a tablet, including using a measuring tape, ruler, or other devices. In addition to using these tools, you can also use common household objects. For example, a standard credit card measures about two-and-a-half inches long by three-and-a-half inches wide, while a letter-size piece of paper is approximately eight-1/2 inches by 11-1/2 inch.

This study analyzed 709 reports in which patients and medical workers reported that the size of a medical tablet or capsule annoyed them. The most common complaints were related to the size of the capsule or tablet. A tablet of the appropriate size is one that fits within the patient’s hand. For example, a tablet that is too long or too wide would irritate a patient. The shortest length of a tablet should be around three-and-a-half inches.

Tablets vary in size depending on the shape of the tablet. A 12-inch tablet, for example, can be either a square, pentagon, diamond, or heart. Its biggest cross-sectional area will be the diameter of the smallest circle, oval, or ellipse. The dimensions of a tablet will be affected by the number of layers it has. The size of a tablet should also be weighed in terms of the number of tablets inside it.

Tablets with a length and width of eight inches are generally easier to hold in the hand than larger ones. This means they are better suited for low-quality content consumption and creation. If you want a tablet with more power, you should look for one with more storage space. However, tablets with larger dimensions are generally less powerful and cannot run high-end games or productivity software. If you aren’t sure what size tablet to choose, try a smaller model that’s seven or eight inches in size.


Pharmaceutical powders undergo compression during the tablet manufacturing process. During compression, the materials experience two types of deformation: plastic deformation and elastic deformation. The latter involves breaking up the particles into smaller parts. These two processes result in different tablet strengths and dissolution times. The exact mechanism of deformation depends on the material properties, speed, and compression force. This article will cover the different types of deformation and how they affect tablet quality.

The amount of water in a powder mass can affect the compaction behavior of the tablet. In addition, the amount of water absorbed at the surface of the particles determines the mechanical properties of the tablet. Hence, the amount of water absorbed on the surface of particles is minimal. However, these particles must undergo special conditions when compaction is done. In addition, the resulting tablet strength may be compromised. This article will address the various variables that affect the process.

During tablet manufacturing, the compression process may lead to lamination. This type of deformation results in a tablet being compressed too quickly. The reason for this is that the precompression step may not remove all entrapped air. Lamination is also associated with high turret speeds and can lead to false hardness tests. In the past, lamination occurred more often when the main compression force was smaller than the precompression force.

The force required to compress a tablet is a function of its mass. A tablet with a constant mass has a high compression force. The force will increase as the thickness increases. If the tablet is too thick, the force will be increased. Further, if the tablet is too thin, the compression force will be reduced, and the tablets will become more fragile. If the force produced is too large, they will break. The weight of the tablet also affects its performance.

The compression process of a tablet should be optimized to avoid air entrapment. The failure to compress air adequately increases the risk of capping and delamination. Some granules require a longer dwell time under peak compression than others. For this reason, the ejection force should be higher for granules with a small particle size. The key to a successful tableting process is to know about the various stages of compression.
