the pharmacological properties of the drug,which means that they
are augmented but qualitatively normal response to the drug
include side effects, toxic effects and consequences of drug
withdrawal.
• They are more common,dose related and mostly preventable and
reversible.

2. Unpredictable (Type B or Bizarre) reactions:- These are
based on peculiarities of the patient and not on drug’s
known action, include allergy and idiosyncrasy.
• They are less common,often non-dose related, generally
more serious and require withdrawal of the drug.

if their genetic basis is known and suitable test to
characterize the individual’s phenotype is performed.
