Suspensions
Sabahat Aziz, 1618112
Abstract
Background - brief, but should set
out the context
Methods – brief summary
Conclusions – relating back to the
aims
Suspensions are a heterogeneous mixture consisting of undissolved particles of one or more
medicinal agents which are mixed within a liquid vehicle. They are taken via the oral route
and… the suspension should be uniformly distributed in order to ensure that it is a uniform
dose.
This experiment was conducted to create 5 suspensions and check the sediment volume at
the times included in the table. These suspensions were prepared in duplicate to assess the
accuracy and mean values. The aim of this practical was to prepare a range of Calamine
suspensions and in doing so determine the effects of various additives on the stability of the
suspensions being prepared. This was done by determining the rate of sedimentation,
appearance and physical appearance of the suspension which was being studied by
observing the colour, height and volume of sedimentation.
Results- key findings! The higher the height of the sediment the greater the
volume of suspension
Introduction
Suspensions are a very common type of dosage form which can be used for different kinds
of enteral administration such as, oral, topical and inhalation and in some cases it can also
be used for parenteral administration. A good suspension is one which is in a homogenous
form upon shaking and easily poured from its container, pleasant taste and uniform particle
size. When a suspension is left upon storage sediments are formed, these sediments have
to be easily re-dispersed after shaking and so forming a homogenous suspension. In some
conditions, suspensions can be advantageous in comparison to a liquid dosage form. For
example, suspensions are much more chemically stable and are greater in taste compared
to solutions,
Suspensions can be classified as either coarse or colloidal depending on particle size.
There are different types of suspensions
