This document offers theories of dispersion and mechanisms of emulsion formation. It discusses four conventional theories of dispersion: viscosity concept, film principle, wedge idea, and interfacial stress principle.

Gastroretentive drug delivery systems are also summarized, like floating drug delivery systems dependant on effervescence or hydrophilic polymers, superior density systems, expandable systems, and bioadhesive systems. The mechanisms and examples of various gastroretentive systems are delivered in below three sentences.

LiverLips 29 Nov 2011 WOW!!! What an unbelievable, indepth response Rajive. Thanks at any time a great deal of for outlining the differences so incredibly informatively. I will be sure to mark this one to be a favorite so that you can return to it for long term viewings.

Liquid dosage kinds are pourable pharmaceutical formulations comprising of API and excipients either dissolved or dispersed in an acceptable solvent/s. These are typically meant to present you with a rapid therapeutic response in those with issues swallowing sound dosage sorts. Liquid dosage sorts can be obtained as ready-to-use liquids or dry powders for reconstitution.

This doc discusses sustained release and controlled release drug formulations. It starts with an introduction and overview of essential ideas. It then discusses the pros and cons of sustained release formulations.

Encapsulation tactics are utilized to preserve and shield components in foods. Microencapsulation coats droplets of liquids, solids or gases in slim movies that control release below diverse problems. This allows controlled release of flavors and safeguards elements. Encapsulation finds purposes in foods like dry beverage mixes and chewing gum exactly where it prolongs taste feeling and shelf lifetime.

This doc discusses oral sustained and controlled release dosage forms. It begins having an introduction and overview of rationality in creating sustained release drug formulations. It defines sustained release as formulations that repeatedly release medication above an extended time period just after just one dose to achieve prolonged therapeutic results.

In addition it describes delayed transit continual release systems built to prolong drug release while in the abdomen, and delayed release systems that focus on distinct web-sites from the GI tract. The key things which make drugs appropriate or unsuitable for sustained release formulations are summarized.

Sustained release is often a sluggish release of medication in excess of a length of time, While Management release releases medication after some time in correlation with focus.

A. Delayed release drugs are intended to release the active ingredient just after a selected hold off, usually to shield the abdomen or to ensure the drug reaches a specific place from the digestive tract.

Pulse Release (PR) systems produce the drug in discrete bursts rather than a ongoing manner. This method mimics the human body's purely natural rhythms and may be helpful for remedies that require "pulses" of medication, like hormone therapy or anti-inflammatory drugs.

This document summarizes a seminar on gastroretentive drug delivery systems (GRDDS). GRDDS are intended to retain drugs within the belly for prolonged periods of time to website permit for sustained drug release. The seminar outlines different GRDDS technologies together with floating, swelling, mucoadhesive, and significant density systems.

Elixir is monophasic clear liquids for oral use for administering potent or nauseous drugs by adding nice flavours. The more info car comprises a high amount of ethanol or sucrose together with antimicrobial preservatives to reinforce the stability of the formulation [twenty five].

Spreadability: Distribute 1g of cream involving two glass slides and measure the spread diameter less than a specified load.
