Carbetapentane; Pseudoephedrine: The cardiovascular effects of pseudoephedrine may reduce the antihypertensive effects produced by alpha-blockers. Monitor blood pressure and heart rate. Mechanism of Action: Terazosin causes peripheral vasodilation by selective, competitive inhibition of vascular postsynaptic alpha1-adrenergic receptors, thereby reducing peripheral vascular resistance and blood pressure. Unlike phenoxybenzamine and phentolamine, which are nonselective alpha-adrenergic blockers, terazosin does not interfere with the feedback mechanism for neurotransmitter release. Because it does not block presynaptic alpha2-receptors, terazosin does not cause reflex activation of norepinephrine release to produce reflex tachycardia. Also, tolerance to its antihypertensive effects does not occur. Terazosin capsules were devoid of mutagenic potential when evaluated in vivo and in vitro the Ames test, in vivo cytogenetics, the dominant lethal test in mice, in vivo Chinese hamster chromosome aberration test and V79 forward mutation assay.

Norepinephrine: Sympathomimetics can antagonize the effects of antihypertensives such as alpha-blockers when administered concomitantly.

Lowe FC "Safety assessment of terazosin in the treatment of patients with symptomatic benign prostatic hyperplasia - a combined analysis.
The symptoms associated with BPH are related to bladder outlet obstruction, which is comprised of two underlying components: a static component and a dynamic component. The static component is a consequence of an increase in prostate size. Over time, the prostate will continue to enlarge. However, clinical studies have demonstrated that the size of the prostate does not correlate with the severity of BPH symptoms or the degree of urinary obstruction. The dynamic component is a function of an increase in smooth muscle tone in the prostate and bladder neck, leading to constriction of the bladder outlet. Smooth muscle tone is mediated by sympathetic nervous stimulation of alpha-1 adrenoceptors, which are abundant in the prostate, prostatic capsule and bladder neck. The reduction in symptoms and improvement in urine flow rates following administration of Terazosin is related to relaxation of smooth muscle produced by blockade of alpha-1 adrenoceptors in the bladder neck and prostate. Because there are relatively few alpha-1 adrenoceptors in the bladder body, Terazosin is able to reduce the bladder outlet obstruction without affecting bladder contractility. Using terazosin with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

If concurrent use of lurasidone and antihypertensive agents is necessary, patients should be counseled on measures to prevent orthostatic hypotension, such as sitting on the edge of the bed for several minutes prior to standing in the morning and rising slowly from a seated position.
