WT – N Enteric film coating is a Phthalate based delayed release coating system. This can be used with solvents (non- aqueous). WT – N can be formulated considering the property of the drug. These coatings are either clear transparent or Pigmented.
Benefits:
This enables the coated tablets to remain intact in the stomach i.e. in acidic environment and then dissolves in the small intestine i.e. more alkaline environment of the.
This coating helps in preventing gastric mucosal irritation.
Protect a drug which is unstable in gastric fluids.
WT – NAQ is delayed release system which can be used in aqueous medium with increased solid contents upto 18 % w/w. The suspension can be prepared in just 45 minutes. Though this is an aqueous coating, the temperature required is as low as 40 ° C – 50° C which enhances the stability of the product.
Benefits:
Enteric property achieved at 5- 7 % weight gain on the tablets.
