AUTOCOIDS
DEFINITION
An organic substance, such as a hormone,
produced in one part of organism and
transported by the blood or lymph to another
part of the organism where it exerts a
physiologic effect on that part.
TYPES OF AUTACOIDS:
´ Amines : Histamine,5-Hydroxytryptamine.
´ Lipids : Prostaglandins, Leukotriens,
´ Platelet activating factor.
´ Peptide : Bradykinin , angiotensin.
HISTAMINE
´ SYNTHESIS AND DEGRADATION OF HISTAMINE
Histidine
decarboxylase
Histamine Imadazole acetic acid
N-methyl transferase
N-methyl histamine
oxidase
Methyl imidazole acetic acid
PHARMACOLOGY
H1 H2 H3
S.M - contraction Gastric gland-acid
secretions
Brain- inhibition of
histamine release- sedation
B.V – vaso dilation B.V-dilation B.V - vaso dilatation
Afferent nerve ending -
stimulation
Heart-postive inotropy Skin , gastric, mucosa-
decrease histamine release
Ganglionic cell- stimulation Uterus - relaxation Lungs , spleen – decrease

PHARMACOLOGY
´ CVS : Arteries are constricted as well as dilated
by direct action of 5-HT.
´ S.M : Stimualtor of GIT.
´ GLANDS : It inhibits gastric secretion. It ulcer
protective property.
´ RESPIRATION: Hyperventilation
´ PLATELETS : 5-HT cause change in shape of
platelets and is a weak aggregator.
THERAPEUTIC USES
´ 5-HT AGONISTS : Anxiolytics ( Buspirone),
Depression( Fluoxetine)
Migraine(Ergot alkaloids)
´ 5-HT ANTAGONISTS: Nausea, emesis,
antineoplastic therapy
(Ondansetron,
Granisetron, Dolasetron)
ADR: Abdominal pain, Muscle cramps, Chest
pain.
