Applications：

Two-Piece Hard Capsules
The manufacture of hard gelatin capsules consists of the dipping of stainless steel mold pins into a gelatin solution, drying, stripping from the pins into a collate, trimming of the caps and bodies, and joining together for shipment. The strength and flexibility, the clarity of the, , , , gelatin, and the movability of the gelatin provide unique characteristics that allow the manufacture of various sizes, colors and designs for assuring a snap closure afte, r filling.

Soft Elastic Gelatin Capsules
Softgels, as they are commonly known today, utilize a gelatin solution that is plasticized with propylene glycol, sorbitol, glycerin or various approved mixtures. Soft gelatin capsules are one-piece and hermetically sealed to enclose a liquid or semi-liquid fill. Soft gelatin capsules are manufacture-formed, filled and sealed in one continuous operation.

The soft gelatin encapsulation process begins with the formation of two sheets called ribbons from a molten gelatin mass, each of which is passed over a die of the desired capsule size and shape. At the point where the two rotating dies meet, the capsule is formed and filled with a liquid that contains the active ingredient in a vehicle. The capsule is then washed to remove the lubricants and dried.

In 1932, R. P. Scherer developed the first rotary die encapsulation system: since that time the technology has been refined into a completely automatic process. The rotary die method has the advantage of producing a capsule with highly accurate dosage levels, can prevent photochemical deterioration of the active ingredient and masks unpleasant tastes.

Tablets
Tablets are defined as solid pharmaceutical dosage forms containing drug substances, with or without diluents, and prepared by compression or molding methods. Tablets are generally prepared by the compression method for most applications. The tablet formulation consists of an active or therapeutic ingredient and several inert materials known as excipients, which are classified as to the role in the tablet process. All tablets contain diluents, binders, glidants and lubricants. Gelatin is used in the preparation of the active (granulation) and as a binder in the tablet. The tableting process consists of several phases of preparation which are necessary to produce the finished tablet.

The first step is typically the granulation of the active ingredient to a particle size close to that of the other ingredients. This is performed by various size enhancement techniques including granulation, extrusion and compression. In all three techniques gelatin is used for its adhesive properties. The natural tack of the gelatin assists in the agglomeration of the particles.

The second step is a granulation technique with all the excipients added. The granulation is controlled to produce a homogeneous and properly sized granulate. Gelatin solutions are used as the binder in this process to form larger agglomerates containing the active, binder, diluents and glidants. The use of gelatin in the granulation process provides an efficient means for reducing fines and maintaining physiological inertness.

Tablet granulates are then compressed into the proper shape, density and size by use of a tablet press. The compression exerted by the tablet press on the powder granulate is such that the agglomerates shatter and upon further compression lock together. The advantage of gelatin is that not only is the shattering of the agglomerates accomplished, but the adhesive properties of the gelatin act as an additional adhesive.

Tablet Coating
Tablets are generally coated to reduce dusting, mask unpleasant taste, and allow for printing and color coatings for product identification. The coating process is more and more becoming aqueous-based which allows for the use of gelatin. Typical formulations for coating include a sugar, pigment, and gelatin to act as a film former. The most popular coating method utilizes a roll coating pan and the addition of the coating solution as a fine spray.

Suppositories
Glycerinated gelatin is typically used as a vehicle for suppositories for insertion into the rectum, vagina or the urethra. The firmness of the finished product is adjusted by varying the gelatin concentration in the formula. The criteria for any suppository formulation are that the base (gelatin) be nontoxic and nonirritating to mucous membranes, compatible with a variety of drugs, the base melts or dissolves in body fluids, and the base should be stable on storage. Suppositories are generally molded by compression or by fusion molding. The gelatin base affords all the desired characteristics required by either method. The two types of gelatin each provide characteristics that are advantageous for formulation dependent upon the active and the area of application.

Type A gelatin is generally adjusted to an acidic pH which is below the isoelectric point, while a Type B gelatin is also adjusted to a pH that is acidic, but in this case the pH is above the isoelectric point. Thus the cationic, anionic, and the nonionic characteristics can be used to promote compatibility with the active, compatibility with the surrounding fluids and temperatures, and enhance or control the bioavailability.

The pH exists where the positive and negative charges are equivalent and the application of an electric charge has no effect. The principal chemical and physical characteristics of a gelatin solution are dependent upon the pH and the ionic strength of the media. The formulation and preparation of the gelatin can in fact modify the isoelectric point in such a way that various physical characteristics can be enhanced. The suppository dosage form is just one example of the use of varied isoelectric points that enhance the performance of the drug delivery system.

Gelatin Emulsions
Gelatin is recognized in many industries as a stabilizer, a texturizing agent, a film former and as a colloidal support media. The preparation of an oil emulsion with gelatin for use as a topical allows the oils to be stored and maintains droplet distribution and droplet size over extended periods. Depending upon the concentration and temperature, the emulsion can be free flowing, semi-solid or solid. These properties are further enhanced with the addition of gums that can provide the additional viscosity for the application, yet retain the colloidal support for the dispersed oil.

Microencapsulation
Gelatin is used to produce microencapsulated oils for various uses both in nutritional and pharmaceutical applications. The traditional method of encapsulation is known as coacervation in which the dispersed oil is encapsulated by gelatin at the interface between the aqueous phase and the non-aqueous phases. Common examples of this are vitamin supplements for various foods and for multi-vitamins. The size and formation of the spherical microcapsules can be controlled by various methods. Typical microcapsules range in size from 5 microns to 500 microns.

Absorbable Gelatin Sponge
Gelatin is used in the form of a sterile, water insoluble sponge (Gelfoam TM ) to control bleeding during surgery. It is later absorbed over a 4 to 6 week period.

Absorbable Gelatin Film
Another application is a sterile, non-antigenic, water-insoluble, absorbable gelatin film (Gelfilm TM obtained from a specially prepared gelatin/formaldehyde solution.

Pastilles and Troches
These products are commonly used as cough drops. Like gelled confections, these products are unique in that in the mouth they are surrounded by a fluid that prevents the active ingredient from being concentrated and creating irritations.

Bacterial Growth Media
As with any pharmaceutical excipient, the level and type of bacteria found is always of concern. Pharmaceutical gelatin is highly purified and sterilized to eliminate these concerns. However, as gelatin is derived from collagen, the ability to perform as a nutrient is itself an application. Special grades of gelatin are useful in bacterial culture media. The specificity of the media to detect and count various bacterial strains is a useful diagnostic and research tool. A variety of media are available that utilize the nutrient properties of gelatin.
