Pharmaceutical
Applications
Tulsion® resins find a number of applications as Excipients in pharmaceutical
formulations.
APPLICATIONS: The use in pharmaceutical
formulations can be classified under one of the following four categories:
-
Drug
stabilization- Drugs for instance, Vitamin B-12 when stored, degenerate
after some time. The stabilization of such drugs can be brought about
using Tulsion® resins
-
Sustained
release- Sustained release formulations ensure that the drug is
released continuously into the body at a slower, but steady rate.
The release of drugs from ion exchange resins depends upon a aeries
of ionic reactions between various body fluids and the drug-resin
complex. The rate of release of drug can be controlled by varying
the particle size, degree of cross-linking and the chemistry of resin.
The release profile can almost be tailor made to suit a particular
application.
-
Taste
masking agent- Certain drugs that have a very bitter taste can
be made relatively tasteless by absorbing the drugs on Tulsion®
exchange resins. The pH in the mouth being on the basic side compared
to the pH in the stomach, the complex drug will not release in the
mouth but only in the stomach. Since while passing through the mouth
the drug remains in complex form, no or very little taste is imparted.
The resins are used in fine mesh form. The nature of the resin used
is also dependant upon the type of drug being masked.
- Tablet
disintegrant- In order to ensure that once a tablet is ingested,
the desired drug is delivered, it is desirable that the tablet disintegrates
uniformly and quickly. External agents are added to a tablet formulation
to ensure the disintegration. Tuslion reins can be used as a disintegrating
agent. This is due to the fact that the resin will swell significantly
once it imbibes moisture. Since the resin in Potassium form swells much
more than the resin in Hydrogen firm, Potassium form of the resin is
preferred in this application.
