HernandezCano N, Herranz P, Lazaro TE, Mayor M, Casado M "Severe cutaneous reaction due to terazosin. 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. progesterone



About terazosin

Terazosin reduces blood pressure in both the supine and standing positions, with more dramatic effects on diastolic blood pressure. These effects are similar to those of prazosin.

Therefore, combined use of silodosin and other alpha-blockers is not recommended. Procainamide: Procainamide can decrease blood pressure and should be used cautiously in patients receiving antihypertensive agents. Intravenous administration of procainamide is more likely to cause hypotensive effects. In cases of overdose, cardiac monitoring should be initiated.

In measurements 24 hours after dosing, heart rate was unchanged. In the treatment of benign prostatic hypertrophy, terazosin blocks alpha1-adrenergic receptors present in the smooth muscle of the bladder neck and prostate, allowing the bladder neck and the prostate to relax.

In patients receiving HCTZ in combination with triamterene, dofetilide AUC increased by 30% and C max by 16%. However, the pharmacodynamic effect increased by 190% QTc increase over time and by 84% maximum QTc increase. The pharmacodynamic effects can be explained by a combination of the increase in dofetilide exposure and the reductions in serum potassium. In the DIAMOND trials, 1252 patients were treated with Tikosyn and diuretics concomitantly, of whom 493 died compared to 508 deaths among the 1248 patients receiving placebo and diuretics.

Blood pressure should be monitored at the end of the dosing interval to be sure control is maintained throughout the interval. It may also be helpful to measure blood pressure 2 to 3 hours after dosing to see if the maximum and minimum responses are similar, and to evaluate symptoms such as dizziness or palpitations which can result from excessive hypotensive response. If response is substantially diminished at 24 hours an increased dose or use of a twice daily regimen can be considered.

Because there is a linear relationship between dofetilide plasma concentration and QTc, concomitant drugs that interfere with the metabolism or renal elimination of dofetilide may increase the risk of arrhythmia Torsade de Pointes. Tikosyn is metabolized to a small degree by the CYP3A4 isoenzyme of the cytochrome P450 system and an inhibitor of this system could increase systemic dofetilide exposure. More important, dofetilide is eliminated by cationic renal secretion, and three inhibitors of this process have been shown to increase systemic dofetilide exposure. The magnitude of the effect on renal elimination by cimetidine, trimethoprim, and ketoconazole all contraindicated concomitant uses with dofetilide suggests that all renal cation transport inhibitors should be contraindicated.

Terazosin capsules, like other alpha-adrenergic blocking agents, can cause marked lowering of blood pressure, especially postural hypotension, and syncope in association with the first dose or first few days of therapy. A similar effect can be anticipated if therapy is interrupted for several days and then restarted. Syncope has also been reported with other alpha-adrenergic blocking agents in association with rapid dosage increases or the introduction of another antihypertensive drug. Syncope is believed to be due to an excessive postural hypotensive effect, although occasionally the syncopal episode has been preceded by a bout of severe supraventricular tachycardia with heart rates of 120 to 160 beats per minute. Additionally, the possibility of the contribution of hemodilution to the symptoms of postural hypotension should be considered.
