Abstract

Medications come in a wide variety of colors and shapes, which are often overlooked as simply being for looks. The visual design of pharmaceuticals, particularly the use of different vibrant colors and shapes, is essential for ensuring that patients adhere to their medication regimen, distinguishing one brand from another, and influencing how effective people believe the medications to be. The main purpose of using bright colors and unique shapes is to give pharmaceutical dosage forms a distinct appearance. Various pharmaceutical preparations, such as tablets, tablet coatings, hard and soft gelatin capsules, liquid oral medications, dental pastes, ointments, and creams, among others, require specific coloring and shapes. The examination of colors' impact on patient adherence, psychological effects, and brand identity is accompanied by the importance of pill shape for ease of swallowing, dosage accuracy, and product recognition. Technological advancements, including 3D printing (3DP), are broadening the scope for innovative drug designs. Regulatory considerations by organizations such as the FDA (Food and Drug Administration) and EMA (European Medicines Agency) guarantee that these designs maintain safety and efficacy while addressing challenges and limitations. This review article initially highlighted on the comprehensive overview of the basic of fancy colour and shapes in pharmaceuticals, their emerging application including their importance and significance in the pharmaceutical drug design. Intermediately describes the technology advancements regarding the design of medicines. Lastly well explained the regulatory aspects related to the colours and shapes for the drug design with their several future prospects.
