Medical pills assortment on white background

Assorted medical pills on white background: a variety of solid oral medications in pharmaceutical presentation.

About this subject

Tablets are the most common solid dosage form, representing about 60% of all medications produced globally. They consist of one or more active ingredients mixed with excipients that ensure cohesion, disintegration, and controlled release. The diversity of colors, sizes, and shapes is not merely aesthetic: each feature can indicate dosage, manufacturer, or even alert to risks of confusion between similar drugs.

In Brazil, the National Health Surveillance Agency (ANVISA) regulates the production and commercialization of tablets, requiring strict quality standards such as dissolution and content uniformity tests. The variety of tablets ranges from simple analgesics like paracetamol and ibuprofen to chronic-use medications for hypertension, diabetes, and psychiatric disorders. The choice between coated, effervescent, or extended-release tablets depends on the route of administration and therapeutic need.

An interesting aspect is that some tablets have score lines to facilitate dose splitting, but not all medications can be broken without compromising efficacy. It is estimated that 1 in 5 patients have difficulty swallowing tablets, leading to the development of alternative forms such as orally disintegrating tablets. The image of an assortment on a white background is common in educational materials and public health campaigns, as it highlights the available variety and the importance of correct treatment adherence.

Tablet production involves technologies such as direct compression, wet or dry granulation, and film coating. Each method influences the drug's bioavailability. Additionally, the pharmaceutical industry invests in smart packaging, such as blisters with barcodes, for traceability and combating counterfeiting, a problem affecting about 10% of medications in developing countries.

Frequently Asked Questions

Why do tablets have different colors?

Colors help identify the medication, preventing accidental swaps. Each manufacturer may use specific colors to distinguish dosages or active ingredients, following regulatory standards.

Can I split any tablet in half?

No. Only tablets with a score line are designed to be split. Splitting tablets without a score line can alter the dose or drug release, compromising treatment.

What does 'coated tablet' mean?

Coated tablets have an outer layer that protects the active ingredient from moisture, light, or gastric acid, and also facilitates swallowing and masks taste.
