Pharmaceutical suspensions are dispersion of particulate drug(s) in a liquid medium (usually aqueous) in which the drug is not readily soluble. Doses formulated as suspensions…
Stability of a pharmaceutical product may be defined as the capability of a particular formulation in a specific container/closure system to remain within its physical,…
Suspensions are commonly referred to as dispersions in which the therapeutic agent is dispersed in the external phase (the vehicle). In an ideal suspension, particles…
Suspensions are an important class of pharmaceutical dosage forms. The advantages of suspension dosage forms include effective dispensing/ administration of insoluble or poorly soluble drugs;…
A suspension is a disperse system in which solid, vehicle-insoluble particles (internal phase) are uniformly suspended by mechanical agitation and formulation design throughout the liquid…
Rheologic consideration is of great importance in the study of the stability of pharmaceutical suspensions. This is because the viscosity of a suspension can modify…
Crystal growth, also known as Ostwald ripening is simply the change in the particle size distribution in pharmaceutical suspensions. It a process whereby small particles…
A pharmaceutical suspension is the dispersion of solid particles (usually a drug) in a liquid medium (usually aqueous) in which the drug is not readily…
Stokes’ law is a generalized equation that describes how certain factors affect the rate of settling in dispersed systems. The implication is that, as the…
Sweetening agents are excipients often added to pharmaceutical dosage forms to mask bitter taste of the partially dissolved drug and to improve palatability in general.…
An antimicrobial agent is a natural or synthetic substance that interferes with the growth and activities of microorganisms that may accidentally contaminate pharmaceutical dosage forms.…
Powders for oral suspension are preparations consisting of solid, loose, dry particles of varying degrees of fine particle size. They are developed as powder mixtures…
Pharmaceutical suspension is a liquid dosage form containing finely divided, undissolved drug particles dispersed throughout a liquid vehicle in which the drug exhibits a minimum…
Pharmaceutical suspensions are liquid dosage forms containing finely divided insoluble materials (the suspensoid) distributed somewhat uniformly throughout the suspending medium (suspending vehicle) in which the…
