PHARMACOLOGY
1.
PHARMACOLOGICAL EFFECTS
(1)
EFFECTS IN HUMANS
In a receptor binding assay using human prostate preparations,
tamsulosin hydrochloride was 2.2 times
more potent than prazosin hydrochloride and 40 times more so than
phentolamine mesylate in

1
-receptor
blocking activity.
(2)
EFFECTS IN ANIMALS
1)
Blockade of

-adrenergic receptors
In a receptor binding assay using isolated rat cerebral membrane and
an _ in vitro _ experiment using
isolated rabbit aorta, tamsulosin hydrochloride inhibited

1
-receptors selectively and competitively.
Its action was 1/2.2 to 22 times more potent than prazosin
hydrochloride and 45 to 140 times more
potent than phentolamine mesylate.
_In vitro _ experiments using isolated rabbit aorta, isolated rat vas
deferens and isolated guinea pig
intestine, tamsulosin hydrochloride proved to be 5,400 to 24,000 times
more selective for

1
-
receptors
than for

2
-receptors.
2)
Effect on the lower urinary tract (urethra and urinary bladder) and
prostate
In a receptor binding assay using isolated smooth muscle from rabbit
urethra, prostate and urinary
bladder base, tamsulosin hydrochloride was 23 to 98 times more potent
than prazosin hydrochloride
in

1
-receptor blocking activity, and 87 to 320 times more potent than
phentolamine mesylate. In
anesthetized dogs, the drug inhibited the

1
-agonist (phenylephrine)-induced increase in intrauretheral
pressure with 13 times greater potency than the increase in diastolic
blood pressure.
