💊 Introduction to Tablet Manufacturing Process
The video introduces the tablet manufacturing process, explaining its various stages aimed at producing high-quality tablets. Tablets, solid dosage forms taken orally, are made by combining active ingredients with excipients. The manufacturing process includes blending, granulation, drying, compression, coating, polishing, branding, quality checks, and packaging. The video also emphasizes the importance of uniform mixing to ensure even distribution of active ingredients.
🌀 Blending and Granulation: Key Manufacturing Steps
Blending is crucial for creating a homogeneous mixture of active ingredients and excipients. Different blenders, such as V-cone, double cone, and octagonal, are used depending on batch size. Granulation, the most critical step, involves turning powders into granules to enhance flow and aid compression. Wet granulation uses liquid, while dry granulation does not. Equipment like rapid mixer granulators and binders are vital to controlling the size, shape, and drug release properties of the granules.
🌬 Drying Methods in Tablet Manufacturing
Granules are dried to remove excess moisture using methods like tray drying and fluid bed drying (FBD). FBD is preferred in pharmaceuticals, where hot air passes through a perforated bowl, drying the material. Special FBD bags increase surface area, helping dry material more effectively while minimizing loss. Moisture content is manually checked during the process to ensure the required level is achieved before proceeding to compression.
💪 Compression: Forming Tablets with Precision
The compression stage transforms granules into tablets using tablet press machines, which apply high pressure to form tablets of specific shapes and sizes. Proper compression affects the physical properties of the tablets, including hardness, thickness, and dissolution rates. Compression must be precise to ensure tablets release the active ingredients as intended, making this a critical step in the manufacturing process.
🎨 Coating and Polishing: Enhancing Tablet Appearance and Function
The coating stage adds a smooth outer layer to tablets, improving appearance, stability, and masking unpleasant tastes. Methods like dipping or spraying apply the coating, and the type of solution determines additional benefits like delayed dissolution in acidic environments (e.g., enteric coatings). After coating, tablets are polished to remove sharp edges and achieve a shiny finish. Branding with food-grade inks can also be added, though it's less common.
🔍 Quality Control and Packaging
Before packaging, each batch undergoes quality control tests such as physical tests, assay, dissolution, and content uniformity to ensure compliance with specifications. Only after passing these checks are tablets packed in blister packs, strips, or bottles. Proper packaging ensures the tablets remain protected and ready for market distribution. Strict adherence to quality standards is essential to safeguard patient safety and maintain product efficacy.
🛡 Importance of Quality and Process Control
The tablet manufacturing process is intricate and involves multiple stages, all of which must be carefully managed to ensure product quality. Failure to follow these steps could compromise tablet safety and efficacy, defeating the purpose of manufacturing.

the tablet manufacturing process is a series of steps that are followed step by step to produce
a quality product all steps have their unique processing and testing to proceed to the next step
tablets are solid dosage forms that are taken orally and are manufactured with a combination
of various ingredients active ingredients are mixed with excipients to manufacture the tablets
quantity and type of excipients are selected according to the type of tablets the process
of tablet manufacturing has several steps those include blending granulation drying compression
coating polishing branding quality checks and packaging after dispensing API and excipients are
added to the blender in a specified Manner and mix together to form a uniform mixture different types
of blenders are used to mix the materials V corn blenders and double cone blenders are commonly
used in Pharmaceuticals octagonal blenders are also used for large batches where the quantity
of material is greater blending helps to make a homogeneous mixture where active material
mixes well throughout the excipients blending plays an important role in tablet manufacturing
because it ensures the even distribution of active ingredients throughout the tablet
granulation is the most important step of tablet manufacturing it is the process of changing powder
into granules granulation improves the flow of the material which makes the compression process
easy there are two main types of granulations one is wet granulation and other is dry granulation
as the name shows where granulation involves the addition of a liquid to the powder and then the
powder is converted into granules while in dry granulation no liquid is used in granules are
formed without the use of liquids the selection of the granulation method depends upon the type
of raw material and the properties of the final product required rapid mixer granulator is the
main equipment used for granulation binders are added with powder in the granulator the
speed of the granulator is adjusted according to the required size and shape of the granules drug
release from the dosage forms depends upon the granulation binders play an important role in
the drug release process granules are dry to remove the excess moisture and solvents used
in the granulation process there are different methods used for drying but tray dryer and fluid
bed dryer is commonly used in pharmaceutical manufacturing fluid bed dryers are widely used
hot air is used in a fluid bed dryer to dry the material it has a perforated Bowl to place the
material and hot air is passed through the material this hot air removes the moisture
and solvents from the material fbd bags are used to dry the material in the fbd these
have finger-like structures to increase the surface area to dry the material easily and
prevent the loss of material by airflow moisture content is checked manually from time to time
until the required moisture level is achieved by the drying process before the compression
compression is the process of tablet making here granules are compressed into tablets of
desired shape and size tablet press machines are used to compress the granules into tablets very
high pressure is applied to the dyes by the punchers material is filled between punches
and dies a compression machine has multiple dies and punches compression is an important step of
tablet manufacturing and the physical properties of a tablet as size shape hardness thickness and
friability are affected by the compression the dissolution of the tablet and the release of
active ingredients are also affected by the compression of the tablet the coating is the
outermost smooth layer of a tablet it gives a lot of advantages to the tablets including improved
appearance and stability reduce dissolution rate and masks the unpleasant taste the coating of
tablets gives a unique identification to the tablets of a brand there are many methods used
for coating but spraying and dipping are common in the dipping method the tablets are dipped in
a coating solution and removed to dry it is required a coating pan to dip in an oven to
dry the tablets in the spray method of coating the coating solution is sprayed using the spray gun
tablets are placed in a perforated coating Pan and the coating solution is sprayed slowly air passes
through the holes of the perforated pan to dry the tablets during the coating process the coating of
the tablets depends upon the type of coating solution used the coating makes it possible to
prevent enteric coated tablets to dissolve in the stomach where conditions are acidic
when tablets are manufactured and coated it is required to polish the tablets to remove any
sharp edges it makes the tablet smooth and shiny any information printed on the tablets is known
as branding branding is not a common concept and it is used rarely by companies edible food grade
inks are used in branding sometimes the name of the tablet or the strength of the active material
is printed on it it is essential to check the quality of the product before its packaging it
ensures that the product is of desired quality and meets the specification quality control
analysts conduct a series of tests specified for the product physical tests a say dissolution
disintegration test and content uniformity are the most common tests done for every batch of
the product after approval from quality control the batch is transferred to the packaging area
tablets are packed according to the requirement of the customers and these are packed in blisters
strips or in bottles after proper packaging tables are shipped to the market for sale
the whole process of tablet manufacturing is a complex process and has different stages every
tablet passes through these steps and finally reaches the market for patients the quality of
the tablets must be maintained throughout the process all steps must be followed strictly
