INTRODUCTION
Biopharmaceutical Classification System (BCS)
BCS Permeabilit
y
Solubility Remarks
Class I High High Those compounds are well absorbed and their
absorption rate is usuallyhigher than excretion
Class II High Low Bioavailability of those products is limited by their
solvation rate
A correlation between the in vivo bioavailability and
the in vitro solvation can be found
Class III Low High Absorption is limitedby the permeation rate but
the drug is solvated very fast. If the formulation
does not change the permeability or gastro-intestinal
duration time,then class I criteria can be applied.
Class IV Low Low Those compounds have a poor bioavailability.
Usuallythey are not well absorbed over the
intestinal mucosa and a high variability is expected.
Introduction
India adores a very
significant position in the
global pharmaceuticals
market.
ADVANTAGE INDIA
With 1.3 billion people and
wide variety of diseases and
patient pool makes this
country very attractive to the
pharmaceutical companies
ADVANTAGE INDIA
Besides large and diverse
patient pool, we also have a
large pool of pharmacist,
scientists and engineers
ADVANTAGE INDIA
India is the largest provider
of generic drugs globally
with the Indian generics
accounting for 20% of global
exports in terms of volume
