About this subject

Tablets are the most common pharmaceutical form worldwide, accounting for about 60% of prescribed medications. In Brazil, the production of solid oral medications strictly follows Anvisa (National Health Surveillance Agency) standards, which require dissolution tests, dose uniformity, and stability. The colors of pills are not merely aesthetic: they help identification by patients and professionals, especially in cases of polypharmacy. Each color may indicate the therapeutic class, such as blue for anxiolytics or red for antibiotics, but there is no global standardization. The shape and coating also have functions: coated tablets protect the active ingredient from moisture and gastric juice, while uncoated ones are cheaper and suitable for stable substances. The Brazilian pharmaceutical industry is one of the largest in the world, with highlights including public laboratories like Farmanguinhos (Fiocruz) and private ones like EMS and Hypera. Local production ensures access to essential medicines, such as antihypertensives and antidiabetics, which are among the most consumed in the country. The image of pills on a white background is often used in educational materials and public health campaigns, such as the Farmácia Popular program, which distributes free medications for chronic diseases. The diversity of colors and sizes also reflects the complexity of modern therapy, where each patient may require a unique combination of drugs.

Frequently Asked Questions

What do the colors of pills mean?

Colors help visual identification by patients and professionals, but there is no global standardization. In Brazil, Anvisa does not regulate colors, but laboratories often use specific shades for therapeutic classes, such as blue for tranquilizers and red for antibiotics.

Are coated tablets better than uncoated ones?

It depends on the need. Coated tablets protect the active ingredient from moisture and stomach acid, making them ideal for sensitive substances. Uncoated tablets are cheaper and suitable for stable drugs. The choice is based on formulation and desired release profile.

How are tablets regulated in Brazil?

Anvisa requires that every solid oral medication undergo dissolution, content uniformity, and stability tests before marketing. Additionally, packaging must include a leaflet with clear information on dosage and contraindications.
