About this subject

Pills are solid dosage forms obtained by compressing powders or granules containing one or more active ingredients. Their production involves processes such as granulation, compression, and coating, which ensure dose uniformity, stability, and controlled release of the drug. The variety of colors and shapes is not merely aesthetic: distinct colors help quick identification by patients and healthcare professionals, preventing medication errors. Additionally, coatings can protect the active ingredient from moisture or gastric juice, or mask unpleasant tastes.

The Brazilian pharmaceutical industry is one of the largest in the world, with emphasis on generic drug production, which accounts for about 30% of the national market. Regulation by Anvisa (National Health Surveillance Agency) requires that all pills sold in the country meet strict quality standards, including dissolution and content uniformity tests. Brazil is also a leader in producing medications for neglected tropical diseases such as Chagas disease and leishmaniasis.

Interestingly, the first modern pill was patented in 1843 by Englishman William Brockedon, who developed a machine for compressing powders. Since then, technology has evolved to include sustained-release, sublingual, and even chewable tablets. In Brazil, pill production moves billions of reais annually, employing thousands of professionals in pharmaceutical laboratories, many located in hubs such as São Paulo, Rio de Janeiro, and Minas Gerais.

Frequently Asked Questions

What do the different colors of pills mean?

Colors help identify the medication, preventing mix-ups and errors. Each manufacturer chooses colors for their products, but there is no universal standard; the color does not necessarily indicate the active ingredient.

How are pills regulated in Brazil?

Anvisa regulates all medications, requiring registration, good manufacturing practices, and quality control. Pills must undergo dissolution, dose uniformity, and stability tests before being marketed.

What is the difference between a pill and a dragee?

Dragees are pills coated with a layer of sugar or polymer, while regular pills may have no coating. The coating can protect the drug or make it easier to swallow.
