Tablets Dosage form is one of a most prefered dosage form all over the world

Almost all drug molecules can be formulated in a tablet and process of manufactiring of tablets too is very simple , and is very flexible.

One can administere 0.01 mg of a drug dose to 1 gm of a drug dose by oral route of administration , by formulating as a tablet.

We have decided to write about tablets manufacturing , formulations.

You will find our articles very intresting as , we are writng out of our experience of actual manufacturing of about 1000 different formulations and drugs , and not merily with therotical experience.

We will provide here on this blog case studies of tablets formulations , trouble shooting , development , tablets machineries tools and many intresting things about tablets formulations and tablets coating , our blog will guide for developing a cost effective and cheaper tablet coating materials .

Tablet Excipient:tablets dosage form advantages and disadvantages

Tablets dosage form Excipient
An excipient is an inactive substance used as a carrier for the active ingredients of a medication. In many cases, an "active" substance (such as aspirin) may not be easily administered and absorbed by the human body; in such cases the substance in question may be dissolved into or mixed with an excipient. Excipients are also sometimes used to bulk up formulations with very potent active ingredients, to allow for convenient and accurate dosage. In addition to their use in the single-dosage quantity, excipients can be used in the manufacturing process to aid in the handling of the active substance concerned.

Depending on the route of administration, and form of medication, various excipients may be used. For oral administration, see Tablet and Capsule. For rectal administration see suppository.
Pharmaceutical Validation
Often, once an active ingredient has been purified, it cannot stay in purified form for long. In many cases it will denature, fall out of solution, or stick to the sides of the container. To stabilize the active ingredient, excipients are added, ensuring that the active ingredient stays "active", and, just as importantly, stable for a sufficiently long period of time that the shelf-life of the product makes it competitive with other products. Thus, the formulation of excipients in many cases is considered a trade secret.
Pharmaceutical Process Validation
Pharmaceutical codes require that all ingredients in drugs, as well as their chemical decomposition products are identified and guaranteed to be safe. For this reason, excipients are only used when absolutely necessary and in the smallest amounts possible.
