About this subject

Tablets are the most common and practical pharmaceutical form for drug administration. They can be classified according to their composition, release mechanism and therapeutic purpose. Among the most frequent types are immediate-release tablets, which dissolve quickly in the stomach, and extended-release tablets, which gradually release the active ingredient throughout the day. There are also effervescent tablets, which dissolve in water before consumption, and sublingual tablets, which are absorbed through the oral mucosa.

In Brazil, tablet production strictly follows the standards of the National Health Surveillance Agency (ANVISA), which requires dissolution tests, dose uniformity and stability. The colors and shapes of tablets are not just aesthetic: each color can indicate a different active ingredient or a specific laboratory, helping patients identify them. For example, light blue tablets may be associated with anxiolytics, while dark red is common in anti-inflammatory drugs.

The diversity of tablets reflects the complexity of disease treatment. Medications for hypertension, diabetes, high cholesterol and depression are often found in this form. The oral route is preferred because it is painless, practical and allows self-administration. However, it is essential to follow the medical prescription regarding time and dose, as treatment efficacy depends on correct adherence.

A curiosity: the first modern tablet was patented in 1843 by British inventor William Brockedon. He created a machine to compress powders into a disc shape, revolutionizing the pharmaceutical industry. Today, compression technology allows millions of tablets to be produced per hour, with precision and quality.
