Capsules - What Kind of Pill is a Capsule
The capsules are designed to contain a drug or medicaments which contain a formulation. There are two types of capsules available, which are hard gelatin and soft gelatin capsules.

Hard gelatin capsule - Discovered by "Murdock" in 1848. That was a two-piece hard gelatin capsule.

These two types of capsules differ in their design as well as their mechanical properties, like;
In soft gelatin capsules, non-aqueous liquids are usually filled, which contain medicinal agents or therapeutic agents that are either dissolved or dispersed within the carrier.
The major component through which a capsule shell is prepared is gelatin. Although many other polymers have already been searched out for the preparation of capsules.
For example, Hydroxypropylmethyl-cellulose and starch.
2) Just like tablets, medicaments present in the capsule contain several components, each of which is present to enhance the biological performance of the dosage forms as well as to facilitate the manufacturers.
The capsules are made from hydroxypropyl methylcellulose commercially available, and contain less residual moisture as compared to the gelatin capsules. Hence, used to fill in hydrolytic drugs. These capsules are a very good alternative for vegetarians.
Type B - It is obtained from animal skins and bones through an alkaline processing method.
The gelatin solutions are obtained by the use of blends, and the main characteristics for manufacturing the capsules are the bloom strength and viscosity.
2) To increase the oral bioavailability of poorly soluble therapeutic or curative agents, generally, soft gelatin capsules may be manufactured. This is used when the capsules are formulated either as a liquid-filled hard gelatin capsule or a soft gelatin capsule.
3) Capsules are one of the convenient formulations utilizing manufacturing substances of abuse or misuse. For example, diazepam, alprazolam, and temazepam.
4) In the capsule formulations, the stability of therapeutic agents may also be improved.
5) Capsule dosage forms are difficult to counterfeit means it is very difficult to make a spurious copy of capsule formulations.
6) Capsule dosage forms are a convenient method of drug administration through which liquid can be administered orally as a unit dosage form to the patients.
7) Due to their portability, ease of administration or use, and elegance, capsules have become the most popular dosage form.
8) Capsules also provide a smooth, slippery, easily swallowed, and tasteless shell for drug substances.
9) Capsules are also beneficial in cases when drugs have an unpleasant taste or odor.
10) In large quantities and in a wide range of colors, capsules can be manufactured very economically.
11) As there are fewer excipients and a minimum pressure required to compact the material. Hence, the capsule dosage form provides ready availability of the contained drug.
2) There is specialized manufacturing equipment required in capsule formulations.
3) The content uniformity, as well as the homogeneity of fill weight-like issues, may be associated with capsule formulations.
4) The capsules should not be used for fluidic or melted materials, as well as highly effervescent materials, because effervescent materials may soften the capsules, while melted powders may dry the gelatin capsule shell to very high brittleness.
These two types of capsules differ in their design as well as their mechanical properties, like;
- The hard gelatin capsules are constituted of two pieces, termed the capsule and the body.
- The hard gelatin capsules are less flexible.
- The soft gelatin capsules constitute a one-piece capsule shell.
- Soft gelatin capsules are more flexible.
In soft gelatin capsules, non-aqueous liquids are usually filled, which contain medicinal agents or therapeutic agents that are either dissolved or dispersed within the carrier.
The major component through which a capsule shell is prepared is gelatin. Although many other polymers have already been searched out for the preparation of capsules.
For example, Hydroxypropylmethyl-cellulose and starch.

What are the 2 Types of Gelatin?
Generally, gelatin is obtained from collagenous material through hydrolysis. Mainly, two types of gelatin are available.Type B - It is obtained from animal skins and bones through an alkaline processing method.
The gelatin solutions are obtained by the use of blends, and the main characteristics for manufacturing the capsules are the bloom strength and viscosity.

It is very well known that the encapsulation of medicinal agents is one of the most popular methods of administering drugs. Capsules are easily administered, tasteless, and very easily filled either unrehearsed, improvised, or commercially in large quantities.
If we consider the prescription of capsules, solid oral dosage forms, then the use of hard gelatin capsules is considered in prescribing either a single drug or a combination of drugs by considering the exact dosage level for an individual patient.
This flexibility shows a huge advantage over tablets. Many patients find taking or swallowing capsules easier than tablets. Hence, they preferred to take this whenever possible.
Due to these kinds of acceptance of patients, the manufacturers also preferred to formulate the capsule dosage forms, although the same product has already been formulated in tablet dosage forms.
Usually, for highly soluble materials like potassium bromide, potassium chloride, or ammonium chloride, capsules are not used for the administration of these materials, because the sudden release of these compounds into the stomach can irritate.

Advantages of Capsules
1) Capsules avoid many unit operations like compression, granulation, and drying that are needed during the manufacturing of tablet dosage forms.2) To increase the oral bioavailability of poorly soluble therapeutic or curative agents, generally, soft gelatin capsules may be manufactured. This is used when the capsules are formulated either as a liquid-filled hard gelatin capsule or a soft gelatin capsule.
3) Capsules are one of the convenient formulations utilizing manufacturing substances of abuse or misuse. For example, diazepam, alprazolam, and temazepam.

Disadvantages of Capsules
1) The capsules that contain liquid fills may have potential stability problems.2) There is specialized manufacturing equipment required in capsule formulations.
3) The content uniformity, as well as the homogeneity of fill weight-like issues, may be associated with capsule formulations.
4) The capsules should not be used for fluidic or melted materials, as well as highly effervescent materials, because effervescent materials may soften the capsules, while melted powders may dry the gelatin capsule shell to very high brittleness.
