Handmade tablets

Tablets have become an integral part of our daily lives, whether they’re simple pain relievers or complex pharmaceutical formulations. These small, easy-to-swallow products that ensure precise dosing have revolutionized medicine, allowing for the simple and effective delivery of active ingredients into the body.

Preparation process

The production of tablets is a complex and sophisticated process that requires several steps and careful attention to ensure the final product is safe and effective.

  1. Preparation of Raw Materials: The first step is the selection and preparation of active ingredients and excipients. The active ingredient is the chemical compound that exerts the therapeutic effect, while excipients (such as binders, fillers, lubricants, and disintegrants) help with the tablet’s formulation, stability, and absorption in the body.
  2. Mixing: The raw materials must be thoroughly mixed to ensure even distribution of the active ingredient. This step is crucial for the quality and efficacy of the tablet.
  3. Wet or Dry Granulation (optional): Granulating the mixture creates uniformly sized particles that can be easily shaped into tablets. In wet granulation, liquid is added to the mixture, which is then dried, while dry granulation involves applying mechanical pressure.
  4. Tableting: The powder blend or granules prepared for tablets are compressed using tablet presses to achieve the final tablet form. This machine compresses the tablet ingredients under high pressure to create a stable and solid tablet.
  5. Coating (optional): Many tablets are coated with a thin film layer that protects the active ingredient from moisture, light, or stomach acid, and facilitates swallowing. These are known as film-coated tablets.
  6. Packaging and Storage: Finally, the finished tablets are appropriately packaged to preserve their quality until consumption.

Applicability

Tablets are among the most widespread forms of medication. They are easy to dose, stable, and have a long shelf life. For the pharmaceutical industry, tablets allow for precise dosing of active ingredients and the creation of various combinations. Several types of tablets are produced, such as immediate-release, extended-release, or enteric-coated versions, which cater to different therapeutic needs.

Did you know?

  • The first tablets were developed in the late 19th century, and since then, technology has continuously evolved. The first modern tablets were often pressed by hand, while today this process is carried out by automated machines.
  • In recent years, 3D printing technology has entered the pharmaceutical industry, enabling the creation of personalized tablets. With this new technology, the distribution of active ingredients and the shape of the tablets can now be precisely adjusted.
  • Researchers are continuously working on developing tablets that contain vaccines. This could revolutionize vaccinations by providing a more easily transportable and applicable format.
  • Although most tablets are tasteless, some manufacturers produce them with special flavors to make them more pleasant to consume. For example, vitamins made for children are often fruit flavored.

Thus, tablet manufacturing is a complex yet fascinating process, serving as a cornerstone of modern medicine. New technologies and innovations are continually shaping and improving this field, ensuring that we will receive effective and safe medications in the future.
