Precise control<br />

ensures uniform coating<br />

Tablet coating is a process that can be summarized as<br />

<strong>the</strong> application of an “edible paint” <strong>to</strong> <strong>the</strong> surface of a<br />

pharmaceutical dosage form. In <strong>the</strong> past, sugar coating was<br />

a common solution for coating tablets, but this process has<br />

many disadvantages. Modern tablet coatings are typically<br />

film coatings, flexible formulations that are applicable <strong>to</strong><br />

a wide range of dosage forms (such as tablets, capsules,<br />

pellets, granules and drug crystals). The tablet coating<br />

process is complex, and involves parameters such as <strong>the</strong><br />

spray pattern, drop size, and nozzle spacing (in addition<br />

<strong>to</strong> multiple o<strong>the</strong>r non-spray related parameters) which<br />

must all be precisely controlled in order <strong>to</strong> ensure uniform<br />

distribution of <strong>the</strong> coating material.<br />
