For each style, it outlines whatever they are, how They're administered and customary examples. The doc is really an instructive reference for the different types of liquid dosage kinds used in pharmaceutical preparations.
This document discusses theories of dispersion and approaches for planning emulsions and suspensions. It handles 4 primary theories of emulsion dispersion: viscousity idea, film or adsorption idea, wedge idea, and interfacial rigidity concept.
4. Pharmaceutical application of emulsions O/W emulsion is handy for oral dosing To protect uncomfortable flavor To raise oral absorption I.
Stearic acid creams (often referred to as vanishing creams) are o/w emulsions and possess a semisolid consistency but are only 15% internal period quantity.
This doc gives an overview of biphasic liquid dosage sorts. It defines biphasic liquids as liquid dosage forms made up of two phases - an undissolved drug stage distributed through a solvent auto period. Suspensions Have got a stable drug dispersed inside of a liquid medium, even though emulsions Have got a liquid drug dispersed in the liquid medium.
Emulsions is often prepared employing numerous approaches based on the scale and elements, like the continental/dry gum process, English/damp gum process, or bottle strategy
Emulsifying agents can reduce coalescence or at the very least lessen its charge to negligible. website It'll type a movie around the dispersed globules. The toughness of the emulsifying agent lies in its ability to kind a organization film.
thirteen. Auxiliary emulsifying agents Auxiliary (secondary) emulsifying agents involve These compounds which can be normally incapable on their own of forming stable emulsion. Their key values lies of their potential to operate as thickening agents and thus assistance stabilize the emulsion.
The get more info difference between a Gel and Cream: A gel is transparent, and a cream isn't. Gels are generally colourless and vanish when utilized. In spite of possessing a colour base, creams are not visible at the time used, Even though gels are absorbed faster.
this ppt is very simple and it has immence importance in Bodily pharmacy. it's been prepared depending on the syllabus of WBUT & is made of informations of elimentary label...
An emulsion is a dispersion of 1 immiscible liquid in just An additional. Emulsions are thermodynamically unstable but can exist in the metastable point out. The stability of an emulsion is dependent upon components like interfacial rigidity, temperature, and entropy of mixing.
An emulsion is a combination of two or more liquids that are usually immiscible with each other. An emulsion is made of two primary factors: the dispersed stage and the continual phase.
The phrase “lotion” is not really an Formal phrase, but is most frequently utilised to explain fluid liquids meant for topical use. Lotions Have got a lubricating result. They are meant to be used in places where by the skin rubs from alone like between the fingers, thighs, and beneath the arms.
Fluorescence exam: Oils possess the property of fluorescence below UV gentle, though drinking water doesn’t. For that reason, O/W emulsion shows a spotty pattern whilst W/O emulsion fluoresces.
