Actually, Pharmaceuticals processing and production have similarities to cook something. Some examples of that are, processing similarities between wet granulation and Ruti or Chapati cooking. Another example of this kind similarities are emulsion production with curry cooking. Though pharmaceuticals processing is similar to cooking but pharmaceuticals processing is done in the more precise, more controlled and more systemic ways to provide stability for prolong period.
Here comes my blog regarding the gastro retentive drug delivery system.
About 40% of the drug compounds are poorly water soluble1. This poor water solubility results in decreased rate and extent of dissolution and hence bioavailability. The formulation of a dosage form for these compounds is a challenging aspect. A number of techniques like micronization, nanonization, salt formation, complexation, solid dispersions, and use of different polymorphic form of the drug are being tried to improve the water solubility of drug compound. Each technique has its own limitations.
PROBLEMS ASSOCIATED WITH TABLET MANUFACTURING
The delivery of the drug through the respiratory tract is called pulmonary drug delivery.
AN INTRODUCTION TO TABLETS
Syrups consists of sugar in water. These are highly concentrated, obviously viscous preparations. And they may or may not contain therapeutic agent.
In simple syrup sucrose at the concentration of 85% is dissolved in water. These are sometimes used as a coating on to the surface of the tablets.
If some therapeutic agent is present, then it is called as medicated syrup.
The word pharmaceutics in pharmacy reflect many subject areas which are all associated with the steps involved in producing of our final finished products  . The question is, are all pharmacists qualified to be involved in pharmaceutical industry and production?
Orally disintegrating tablets also called as fast dissolving or mouth dissolving tablets are such kind of dosage forms which when placed in mouth disintegrates rapidly in a matter of seconds(1). They are different from lozenges or buccal tablets which require more than a minute to get dissolved in mouth(1). Any dosage form or a novel drug delivery system which improves patient compliance is of great interest to scientists in which orally disintegrating tablets stands first among them.
