Every day, millions of individuals ingest pharmaceutical capsules all around the world. Have you ever thought about where they originate from? The gelatin capsule, which has been the traditional shell excipient for almost a century, is the subject of this article. We also take a look at the vegetarian-friendly alternative shell excipients that have been created.
Capsules assist in increasing patient compliance. This is due to the fact that capsules are smaller, making them simpler to swallow, and they completely mask the unpleasant flavours associated with liquid medicine or gritty tablets. Another advantage of capsules is that they can be customised, meaning that they can be made in a variety of forms, sizes, and colours for easy identification.
Gelatin Capsules are one of the quite popular capsules in the world. Plant-based alternatives, such as HPMC and modified starch, have recently entered the market to meet the needs of vegetarians.
Hard Shell Capsules are solid, cylindrical shells made up of two parts: the body and the cap, that are filled with dry or liquid substances and then sealed to prevent leakage. This is one of the most traditional types of medicinal capsule.
Soft Capsules are a type of capsule that can be used orally.
Soft capsules (also known as softgels) are one-piece capsules that are manufactured in a single step. Despite the fact that the manufacturing procedure for soft capsules is more complicated, this method allows producers to create capsules with liquid or semi-liquid contents in a variety of forms and sizes.
Consumers prefer gelatin capsules because they are natural.
Consumers have been increasingly aware of the origin, sustainability, and health elements of the products they purchase in recent years. This is spurred in part by the tightening of food labelling legislation and openness, such as the EU rule on consumer food information. Gelatin's use as a culinary ingredient can be dated back to the Middle Ages, when it was utilised to make jellied food preparations. It is becoming a commonplace element of our life and a preferred ingredient for many customers all around the world. Gelatin comes from natural sources and is made by partially hydrolyzing collagen found in animal skins and bones.
What is actually natural, one could wonder? When we ask for a sustainable product, what exactly are we searching for? Is it just the origin, or does it also include the process and the possibility of chemical modification? Capsules made from plant-based ingredients respond to the growing desire for vegetarian products, yet they appear to ignore the natural urge. Gelatin capsules, on the other hand, respond to the natural choice, but they can only ignore the vegetarian trend.Dissolution / Active Pharmaceutical Ingredient (API)
This is the rate at which the capsule dissolves in the stomach, allowing the body to absorb the active substance. For example, gelatin has one of the finest - if not the best - API dissolving rates, allowing the API to be readily absorbed by the body. It's one of the most crucial factors for pharmaceutical companies to consider. In most cases, the body's breakdown process is painless. However, capsule shells can cross-link if they are exposed to excessive heat or humidity, or if certain aldehydes are present. HPMC does not suffer from crosslinking issues because to its low humidity.
Some important differences between hard and soft gelatin capsules
The production of hard and soft capsules is a time-consuming operation that necessitates exact calculations. The performance of the capsules may vary after they have been created. Let's look at some of the most important technical aspects of hard and soft capsules.
The advantages of capsules
Capsules are dissolvable capsules that contain an active component (such as a medication). They're a safe alternative to tablets, and they have a lot of advantages over tablets. To begin with, capsules are less difficult to make than tablets. This reduces the time it takes to develop a product, resulting in a shorter time to market. Pharmaceutical companies can also encapsulate liquid and semi-liquid fillers with capsule technology, which is not possible with tablets.Capsules assist in increasing patient compliance.
