Hard Capsules Health Products Development

Hard capsules are solid dosage forms in which one or more inert substances are encapsulated in a small shell. They are a proven dosage form that can provide a solution to many of today's nutraceutical formulation challenges. Hard gelatin capsule shells consist of two prefabricated cylindrical sections, each with a rounded closed end and an open end. The main body is slightly smaller in diameter than the lid and is mounted inside the lid. CD Formulation provides professional hard capsule health products development for our clients, and we offer a full range of integrated services to effectively help our clients complete an accelerated product commercialization process.

Hard Capsules Health Products Development


The hard-sealed gelatin of the capsule acts as an oxygen barrier and maintains the quality of the capsule and its components. The gelatin capsule shell also helps to extend the shelf life of the capsule. The size of the selected hard gelatin capsule is determined by the prescription requirements, including the dose of the active ingredient and the density and compaction characteristics of the other components. The first step in estimating the optimal capsule size for a given product is to determine the density of the formulation using the vibrancy density of the powder and the bulk density of the pills, small tablets and granules. The measured formulation density, target fill weight and capsule volume can then be used to calculate the appropriate capsule size.
