Types of Capsules according to Materials

As mentioned above, a versatile auto capsule filling machine can fill types of capsules. Jednakże, how are capsules classified into different types? Here is an insight into this issue.

You may ask: What are medicine capsules made of? What is a gel capsule? Categorized according to material, types of capsules can be content as shown below:

1. Kapsułki żelatynowe

Produced from gelatin derived mainly from animals’ (such as cattle and fish) skins and bones, gelatin capsules are a traditional capsule form to enclose medications, supplements or other active ingredients. Na przykład, to encapsulate fish oil, fish gelatin capsules are ideal for their desirable resolvability with aliphatic acid.

Gelatin is biocompatible, biodegradable and non-toxic, and it has benefits including the ease of swallowing, staying tasteless and odorless, and rapid dissolution. What’s more, gelatin capsules have better performance in their long shelf life.

Ponadto, by controlling the dissolution rate and release degree of active ingredients in the gastrointestinal tract, gelatin capsules enable the drug to be released at specific parts in a human body, playing a role of targeted therapy.

2. Vegetarian Capsules

For vegetarian consumers who prefer plant-based diets, vegetarian capsules, inclusive of HPMC capsules and pullulan ones, are a good option. Vegetarian capsules do not contain animal-derived allergens, and ingredients are natural and healthy. Dlatego, for those allergic to animal proteins, this type of capsules obviously reduces the risk of allergic reactions.

There is an issue of gelatin vs vegetarian capsules. In comparison with gelatin capsules, vegetarian capsules enjoy wider consumer acceptance, enhanced chemical stability and pH compatibility, and friendliness to environmental sustainability. Jednakże, in the aspect of cost, vegetarian capsules are 3 times more expensive than gelatin ones.

2-1 HPMC Capsules

HPMC capsules are made from hydroxypropyl methylcellulose, a water-soluble polymer gained from cellulose. Herbal products, such as Comvita immune propolis and PSeti quercetin, are packaged in HPMC capsules due to their effectiveness in ensuring product quality.

What Are HPMC Capsules’ Advantages over Pullulan Capsules?

· With raw materials derived from wood pulp or cotton, HPMC capsules are generally of lower costs compared to pullulan capsules, and the large-scale production is more economical.

· Due to the cost-effectiveness and the well-established supply chain, HPMC capsules are more commonly used than pullulan capsules in pharmaceutical industry.

· Owning the chemical stability across a wide pH range (acidic to alkaline), HPMC are compatible with a broader range of formulations.

2-2 Pullulan Capsules

In terms of pullulan capsules made from fermented starch, they are used to encapsulate drugs and nutritional ingredients, especially those sensitive to moisture and oxygen, protecting the ingredient stability.

What Are Advantages of Pullulan Capsules over HPMC Capsules?

· Outwardly, pullulan capsules are exceptionally clear and glossy, staying more visually appealing compared to HPMC capsules.

· Because of the relatively simple production process, pullulan capsules have higher purity and a higher degree of naturalness.

· This type of capsules, highly resistant to cross-linking, can ensure more reliable dissolution and dissolve faster than HPMC capsules

3 Starch and PVA Capsules

Starch and PVA capsules have much shorter histories than those of gelatin and vegetarian capsules. Starch capsules are mainly made from starch, including that from corn, potatoes, tapioca and wheat. These starches are processed and refined to get highly purified starch for encapsulation.

PVA capsules are made from polyvinyl alcohol— a synthetic polymer material, possessing unique benefits such as good water solubility and film-forming properties.

These two capsule forms are widely used in pharmaceutical and health product industries to encapsulate medicines, vitamins, minerals and other active ingredients. Their shells are strong enough to contain kinds of formulation, especially suitable for containing products that require slow release in human bodies.

Types of Capsules according to Textures

Categorized according to functions, types of kapsułki include hard capsules and soft capsules.

1. Hard Capsules

Usually known as hard gelatin capsules, hard capsules are traditionally made from gelatin but can also be made from plant-based materials. Suitable for enclosing both medicines and vitamins, hard gel capsules generally encapsulate solid oral dosage forms or sometimes even liquid formulations, protecting medications encased in a gelatin shell.

2. Soft Capsules

Known as soft gel capsules, soft capsules are soft in the capsule shell and ideal for enclosing liquid dosage forms including fish oil or other supplements. With soft texture facilitating the ease of swallowing, the capsules are usually made from gelatin but can also be made from vegetarian alternatives like cellulose.

Not similar to hard capsules that have two parts (a body and a cap), a soft capsule is made from a single piece of gelatin or other material. Soft capsules are typically filled with liquid or semi-solid ingredients.

Types of Capsules according to Functions

Categorized according to functions, types of kapsułki can be shown in this table:

1. Enteric Capsules

Coated with a kind of pH-sensitive polymer, enteric capsules have special layers as their coatings resist dissolution in stomach acid, in order to reach the purpose that active ingredients enter small intestines, breaking down in the more alkaline environment of small intestines.

2. Sustained-release Capsules

Designed to release active ingredients slowly and continuously, sustained-release capsules can let the drug releasing extend over a period for about 10 hours or longer, leading to stable drug releasing levels and the consistency of drugs’ therapeutic concentration in the bloodstream.

3. Controlled-release Capsules

Controlled-release capsules target specific locations of intestinal tracts, providing more precise control on drug release compared to sustained-release one. What’s more, controlled-release capsules can maintain therapeutic drug levels for 24 hours or above, thereby reducing medicine doses and simplifying medication regimens.

Types of Capsules according to Uses

Categorized according to the application, types of capsules are shown in this table:

1. Pharmaceutical Capsules

Drug kapsułki serve the purpose of encapsulating active pharmaceutical ingredients (API) in shells, typically made of gelatin or plant-based materials. They are used to shield medicines from the surrounding and ensure the delivery of medications for therapeutic uses, improving dosage accuracy and the effectiveness of curing diseases.

2. Dietary Supplement Capsules

When it comes to shapes of capsules, dietary supplement capsules are more good-looking. They are generally more consumer-oriented and visually attractive. Different from pharmaceutical capsules that contain API, Dietary supplement capsules may contain vitamins, herbal ingredients, and fatty acids like Omega 3, which support human health but not treat diseases.

Comparing Capsules of Different Outward Features

1. Rozmiary kapsułek

Selecting medications with the capsule size suitable for your dosage demand would be better to manage personal health.

Ranging from size 000 na rozmiar 5, capsule sizes differ with larger numbers indicating smaller volumes. Different formulations and specific dosage requirements influence the choice of capsule sizes.
