For the treatment of high blood pressure, it may take several weeks before you get the full benefit of this drug. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. Do not skip doses or stop taking labetalol without first talking to your doctor. Stopping suddenly may make your condition worse. Pharmacodynamics: The capacity of labetalol HCl to block alpha receptors in man has been demonstrated by attenuation of the pressor effect of phenylephrine and by a significant reduction of the pressor response caused by immersing the hand in ice-cold water “cold-pressor test”. Labetalol HCl's beta 1-receptor blockade in man was demonstrated by a small decrease in the resting heart rate, attenuation of tachycardia produced by isoproterenol or exercise, and by attenuation of the reflex tachycardia to the hypotension produced by amyl nitrite. Beta 2-receptor blockade was demonstrated by inhibition of the isoproterenol-induced fall in diastolic blood pressure. Both the alpha- and beta-blocking actions of orally administered labetalol HCl contribute to a decrease in blood pressure in hypertensive patients. Labetalol HCl consistently, in dose-related fashion, blunted increases in exercise-induced blood pressure and heart rate, and in their double product. The pulmonary circulation during exercise was not affected by labetalol HCl dosing.
The recommended initial dosage of Trandate is 100 mg twice daily. The usual maintenance dose range is 200 - 400 mg twice daily.

The peak effects of single oral doses of labetalol HCl occur within 2 to 4 hours. The duration of effect depends upon dose, lasting at least 8 hours following single oral doses of 100 mg and more than 12 hours following single oral doses of 300 mg. The maximum, steady-state blood pressure response upon oral, twice-a-day dosing occurs within 24 to 72 hours. Lab tests, including liver function, may be performed while you use Trandate. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.

Chronic Bronchitis and Emphysema: Patients with bronchospastic disease should, in general, not receive beta-blockers. Labetalol HCl tablets may be used with caution, however, in patients who do not respond to, or cannot tolerate, other antihypertensive agents. It is prudent, if labetalol HCl tablets are used, to use the smallest effective dose, so that inhibition of endogenous or exogenous beta-agonists is minimized. The metabolism of labetalol is mainly through conjugation to glucuronide metabolites. The metabolites are present in plasma and are excreted in the urine and, via the bile, into the feces. Approximately 55% to 60% of a dose appears in the urine as conjugates or unchanged labetalol within the first 24 hours of dosing.

Trandate should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed. It works by blocking the action of certain natural chemicals in your body such as on the and vessels. Subsequent oral dosing with the tablet formulation should begin when it has been established that the supine diastolic blood pressure has begun to rise. Beta 2-receptor blockade was demonstrated by inhibition of the isoproterenol-induced fall in diastolic blood pressure. Both the alpha-and beta-blocking actions of orally administered labetalol HCl contribute to a decrease in blood pressure in hypertensive patients. Labetalol HCl consistently, in dose-related fashion, blunted increases in exercise-induced blood pressure and heart rate, and in their double product. The pulmonary circulation during exercise was not affected by labetalol HCl dosing. Decreased sexual ability has been reported rarely. If any of these effects persist or worsen, tell your doctor or promptly. Zimmerman, 1985. In addition prazosin has no effect on the presynaptic α 2 receptors in sympathetic nerve endings that innervate the heart. As a result, any changes in sympathetic tone to the heart are minimized due to activation of negative feedback. In contrast, the blood pressure lowering effects of non-selective alpha blockers, such as phentolamine, are associated with a marked reflex tachycardia due to blunting of inhibitory presynaptic α 2 feedback that suppresses the release of norepinephrine when synaptic levels of the neurotransmitter rise. Do not share this medication with others. Use Trandate tablets with caution in the ELDERLY; they may be more sensitive to its effects, especially dizziness, lightheadedness, or fainting. atopica

As with all drugs with beta-blocking activity, certain advice to patients being treated with labetalol HCl is warranted. While no incident of the abrupt withdrawal phenomenon exacerbation of angina pectoris has been reported with labetalol HCl, dosing with TRANDATE Tablets should not be interrupted or discontinued without a physician's advice.

Exacerbation of Ischemic Heart Disease Following Abrupt Withdrawal: Angina pectoris has not been reported upon labetalol HCl discontinuation. However, hypersensitivity to catecholamines has been observed in patients withdrawn from beta-blocker therapy; exacerbation of angina and, in some cases, myocardial infarction have occurred after abrupt discontinuation of such therapy. When discontinuing chronically administered labetalol HCl tablets, particularly in patients with ischemic heart disease, the dosage should be gradually reduced over a period of 1 to 2 weeks and the patient should be carefully monitored. If angina markedly worsens or acute coronary insufficiency develops, therapy with labetalol HCl tablets should be reinstituted promptly, at least temporarily, and other measures appropriate for the management of unstable angina should be taken. IV administration, respectively. Beta 2-agonist activity has been demonstrated in animals with minimal beta 1-agonist ISA activity detected. In animals, at doses greater than those required for alpha- or beta-adrenergic blockade, a membrane stabilizing effect has been demonstrated. Carvedilol, specifically, is indicated for use with these agents in the treatment of mild to severe heart failure of ischemic or cardiomyopathic origin. There is also increasing evidence that the addition of a beta-blocker to standard therapy can improve morbidity and mortality in patients with advanced heart failure, although it is uncertain whether effectiveness varies significantly with the different agents. Data from one meta-analysis study suggest a greater reduction of mortality risk for nonselective beta-blockers than for beta-1 selective agents. paka.info reductil

AU second and third trimester UK, US: This drug should be used during pregnancy only if the benefit outweighs the risk. Although beta-adrenergic receptor blockade is useful in the treatment of angina and hypertension, there are also situations in which sympathetic stimulation is vital. For example, in patients with severely damaged hearts, adequate ventricular function may depend on sympathetic drive. Beta-adrenergic blockade may worsen A-V block by preventing the necessary facilitating effects of sympathetic activity on conduction. Beta2-adrenergic blockade results in passive bronchial constriction by interfering with endogenous adrenergic bronchodilator activity in patients subject to bronchospasm, and it may also interfere with exogenous bronchodilators in such patients.

Single oral doses of labetalol HCl administered to patients with coronary artery disease had no significant effect on sinus rate, intraventricular conduction, or QRS duration. The atrioventricular A-V conduction time was modestly prolonged in two of seven patients. In another study, IV labetalol HCl slightly prolonged A-V nodal conduction time and atrial effective refractory period with only small changes in heart rate. The effects on A-V nodal refractoriness were inconsistent. Store between 36-86 degrees F 2-30 degrees C away from light and moisture. not store in the bathroom.

The plasma half-life of labetalol following oral administration is about 6 to 8 hours. Steady-state plasma levels of labetalol during repetitive dosing are reached by about the third day of dosing.
