This method was high-yield, consistent, and reduced waste. His innovation used a rotary die to produce the capsules. All modern soft-gel encapsulation uses variations of a process developed by R. Although some companies still use this method, the equipment is no longer produced commercially. Later on, methods were developed that used sets of plates with pockets to form the capsules. They used individual iron molds for their process, filling the capsules individually with a medicine dropper.

In 1833, Mothes and Dublanc were granted a patent for a method to produce a single-piece gelatin capsule that was sealed with a drop of gelatin solution. Single-piece gel encapsulation ('soft capsules') Soft gel capsules. For this reason, producers of drugs such as OTC analgesics wanting to emphasize the strength of their product developed the 'caplet', a portmanteau of 'capsule-shaped tablet', to tie this positive association to more efficiently-produced tablet pills, as well as being an easier-to-swallow shape than the usual disk-shaped tablet medication. Since their inception, capsules have been viewed by consumers as the most efficient method of taking medication. Other ingredients can be added to the gelling agent solution including plasticizers such as glycerin or sorbitol to decrease the capsule's hardness, coloring agents, preservatives, disintegrants, lubricants and surface treatment.

Soft-shelled capsules, primarily used for oils and for active ingredients that are dissolved or suspended in oil.īoth of these classes of capsules are made from aqueous solutions of gelling agents, such as animal protein (mainly gelatin) or plant polysaccharides or their derivatives (such as carrageenans and modified forms of starch and cellulose).

These are made in two-halves: a smaller-diameter “body” that is filled and then sealed using a larger-diameter “cap”. processes of extrusion or spheronization.

Hard-shelled capsules, which contain dry, powdered ingredients or miniature pellets made by e.g.

In the manufacture of pharmaceuticals, encapsulation refers to a range of dosage forms-techniques used to enclose medicines-in a relatively stable shell known as a capsule, allowing them to, for example, be taken orally or be used as suppositories. Relatively stable shell containing medicine
