Medical pills assortment on white background

Pills of different colors and shapes arranged on a white background represent the diversity of the modern pharmaceutical industry.

About this subject

Pills are the most common dosage form worldwide, accounting for about 70% of all prescribed medications. Their popularity stems from ease of administration, chemical stability, and dosage accuracy. The variety of colors and shapes is not merely aesthetic: each color may indicate a therapeutic class (such as yellow for diuretics or blue for sedatives), and shapes aid identification for polypharmacy patients. In Brazil, the National Health Surveillance Agency (ANVISA) regulates production and labeling, requiring each pill to have a unique marking. Production involves processes like direct compression or wet granulation, and coatings can control active ingredient release. The Brazilian pharmaceutical industry, one of the largest globally, produces billions of pills annually, supplying the public health system (SUS) and the private market. Despite their practicality, improper use of pills is a global challenge: it is estimated that 50% of patients do not take their medications correctly, leading to therapeutic failures and antimicrobial resistance. The image of an assortment of pills evokes the complexity of pharmacological care and the need for education on medication administration.
