摘要: This invention provides a method of treating benign prostatic hyperplasia in a subject which comprises administering to the subject a therapeutically effective amount of an .alpha..sub.1C antagonist which (a) binds to a human .alpha..sub.1C adrenergic receptor with a binding affinity greater than 100-fold higher than the binding affinity with which the .alpha..sub.1C antagonist binds to a human .alpha..sub.1A adrenergic receptor, a human .alpha..sub.1B adrenergic receptor, and a human histamine H.sub.1 receptor; and (b) binds to a human .alpha..sub.2 adrenergic receptor with a binding affinity which is greater than 100-fold lower than the binding affinity with which the .alpha..sub.1C antagonist binds to such .alpha..sub.1C adrenergic receptor.The invention further provides a method of inhibiting contraction of a prostate tissue which comprises contacting the prostate tissue with an effective contraction-inhibiting amount of an .alpha..sub.1C antagonist which (a) binds to a human .alpha..sub.1C adrenergic receptor with a binding affinity greater than 100-fold higher than the binding affinity with which the .alpha..sub.1C antagonist binds to a human .alpha..sub.1A adrenergic receptor, a human .alpha..sub.1B adrenergic receptor, and a human histamine H.sub.1 receptor; and (b) binds to a human .alpha..sub.2 adrenergic receptor with a binding affinity which is greater than 100-fold lower than the binding affinity with which the .alpha..sub.1C antagonist binds to such .alpha..sub.1C adrenergic receptor.
