-
Site of action
means drug should be delivered it target site, or specific part of the body.
-
Mechanism of action
How the drug works.
-
Drug action
- Drug move through the body to its target site.
- Alteration of the existing biological and philological part of the body.
-
ROA
Route of Administration
-
Pharmaceuticals and Pharmacologically active.
If the drug does what it intended to do, Its called Pharmacological active, it is the process of biological and chemical interactions.
-
Drug action
Drug action is the result of of an interaction between a molecule and a functionally important structure in human body, which alters biochemical or philological function.
-
Pharmacodynamics
It means the molecular interaction of the drug with body's receptors which leads to desired response.
-
pharmacokinatics
the study of what body does it to drugs, Process of ADME.
-
Medication and drug
Drug is a substance or chemical capable of altering biological or chemical and philological process in the body. These responses can be either desirable or undesirable.
-
Mediation
A medication in contrast, is drug that is used for purpose of restoring a dysfunctional or pathological process in the body it its desired process.
-
Pharmalogic activity
the theraputic response is called pharmalogic activity
-
Magic bullet
Drug travels through the body though blood stream, it might produce other responses. When drug . The drug only effect site of action , not other things is called magic bullet.
-
Side Effects
Drugs side effects are usually related to when drug effect tissue where the response is not needed or not intended .
-
Biopharmaceutics
- Is the study of design and development of drug dosage form that will
- 1- deliver the chemically active form of drug in sufficient amount
- 2- withstand phsiological condition inside the patient body and
- 3- release all the active drug at a tolerable rate.
-
Drug + Receptor = [Drug-Receptor] =>Pharmalogical effect]
- [D] + [R] => [DR] ____ > Effect
- <=
-
Affinity
- The strength of the drug-receoptor is measure in affinity.
- Such a drug should be close enough "imitator" of the 5-HT neurotransmeter to fit into the receptor
-
Agonist
Agonist is the drug that produce stimulation type response.Agnoist is the drug that interacts with the receptor site and blocks or depress the normal response from receptors
