Tablet formulation is the process of creating solid dosage forms of medication, known as tablets. This involves combining active pharmaceutical ingredients (APIs) with excipients, which are inactive substances that help in the tablet's stability, absorption, and overall effectiveness. The formulation must ensure that the tablet can be easily manufactured, stored, and delivered to the patient. The key steps in tablet formulation include mixing the ingredients, granulation, compression, and coating. Granulation helps to improve the flow and compressibility of the powder mixture, while compression shapes the tablet. Finally, coating can enhance the tablet's appearance and protect it from environmental factors.
