Polacrillin Potassium is derived from acrylate base
polymer as per USP/NF. It is an effective super disintegrant as well as
dissolution improver in solid dosage forms like tablets, Capsules , Pellets
etc.
Polacrillin Potassium is available in white free flowing powder hence it is
more suitable in direct compression system.
Polacrillin Potassium is a very high purity polymer
finding use in Pharmaceutical formulation as a superb TABLET DISINTEGRANT
for oral dosage formulations.
Required quantity is form 0.4% to 2% of avg. Weight
of tablet on lubrication stage.
Disintegrant Agent : Polacrillin Potassium
has a very high swelling tendency on hydration either in contact with water
or G.I. Fluids causing fast disintegration without the formation of lumps
and thus acts as an effective TABLET DISINTEGRANT.
ADVANTAGES
- Rapid Disintegrant.
- Elimination of lump formation.
- Compatibility with other theraupatic agents and excipients.
- Imparts excellent strength to the tablet and also eliminates the
sticking to the dies and punches.
- Improves bioavailability of the drug.
- Tablet breaks uniformly with each particle as separate identity.
For direct compression system, prepare drug granules
with P.V.P. Or HPMC and avoiding use of starch or gelling binder.In these
granules ,mix polacrillin potassium first and then mix lubricants. Prepare
the tablet and put it in water or G.I. Fluid. Polacrillin Potassium absorbs
water and break the tablet. A Ranitidine Hydrochloride tablet direct
compression system was carried out to evalute the disintegration effect of
Polacrillin Potassium in Comparison with cross P.V.P. And Cross Carmellose
Sodium Using 1% the results are shown in figure
Polacrillin Potassium is high molecular weight
polymer, so doesn't get absorbed by body tissues & is safe for human
cosumption. It has no physiological action at recommended dosage & it is
non-toxic.
Store in tightly closed container. Keep away from
moisture. If moisture is absorbed dry at 90*C to 100*C remove moisture
content below 10%
