A nonselective beta-adrenergic blocking agent with intrinsic sympathomimetic activity that is indicated in the management of hypertension.
Hussar, D.A. (ed.). Modell's Drugs in Current Use and New Drugs. 38th ed. New York, NY: Springer Publishing Co., 1992., p. 131
In the management of hypertension or chronic stable angina pectoris, many clinicians prefer to use low dosages of a beta1-selective adrenergic blocking agent (eg; atenolol, metoprolol), rather than a nonselective agent like pindolol, in patients with chronic obstructive pulmonary disease or insulin-dependent diabetes mellitus. However, selectivity of these agents is relative and dose dependent.

Contraindicted in patients with bronchial asthma, overt cardiac failure, cardiogenic shock, second and third degree heart block, and severe bradycardia. Adverse reactions include dizziness, fatigue, insomnia, edema, nausea, and muscle and joint pain. Use is best avoided in patients with bronchospastic diseases and therapy in diabetic patients must be closely monitored. When therapy is to be discontinued, the dosage should be gradually reduced over a period of 1 to 2 weeks.
Hussar, D.A. (ed.). Modell's Drugs in Current Use and New Drugs. 38th ed. New York, NY: Springer Publishing Co., 1992., p. 131
Abrupt withdrawal of pindolol may exacerbate angina symptoms or precipitate myocardial infarction in patients with coronary artery disease, or precipitate thyroid crisis in patients with thyrotoxicosis. Therefore, patients receiving pindolol (especially those with ischemic heart disease) should be warned not to interrupt or discontinue therapy without consulting their physician. When discontinuance of long term pindolol therapy is planned, particularly in patients with ischemic heart disease, dosage of the drug should be gradually reduced over a period of 1-2 wk. When pindolol therapy is discontinued, patients should be carefully monitored. If exacerbation of angina occurs or acute coronary insufficiency develops after pindolol therapy is interrupted or discontinued, treatment with the drug should be reinstituted promptly, at least temporarily, and appropriate measures for the management of unstable angina pectoris should be initiated. Because coronary artery disease is common and may be unrecognized, the manufacturers caution that it may be prudent not to discontinue pindolol therapy abruptly, even in patients being treated only for hypertension.
McEvoy, G.K. (ed.). American Hospital Formulary Service - Drug Information 2003. Bethesda, MD: American Society of Health-System Pharmacists, Inc. 2003 (Plus Supplements)., p. 1777
Pindolol should be used with caution in patients undergoing major surgery involving general anesthesia. The necessity of withdrawing beta-adrenergic blocking therapy prior to major surgery is controversial, but the manufacturers state that, if possible, pindolol should be withdrawn well before surgery. Severe, protracted hypotension and difficulty in restarting or maintaining a heart beat have occurred during surgery in some patients who have received beta-adrenergic blocking agents. If patients continue to receive pindolol prior to surgery, the anesthesiologist should be advised that the patient is receiving the drug. The manufacturers recommend administration of beta-agonists (eg; dopamine, dobutamine, isoproterenol) to reverse pindolol's beta-adrenergic blockade if necessary during surgery.

Pindolol is indicated in the management of hypertension. In Canada, it is also indicated in the prophylaxis of angina.
Pindolol is a nonselective beta blocker indicated in the management of hypertension and prophylaxis of angina. It has a short duration of action as it is given twice daily, and a wide therapeutic window as doses can range from 10-60 mg/day. Patients should be counselled regarding the risk of cardiac failure, exacerbating ischemic heart disease with sudden withdrawal, nonallergic bronchospasm, masking hypoglycemia in diabetics, and masking hyperthyroidism.

Absorption
The mean oral bioavailability of pindolol is 87-92%. A 5 mg oral dose reaches a Cmax of 33.1 5.2 ng/mL, with a Tmax of 1-2 hours.
Route of Elimination
80% of an oral dose is eliminated in the urine, with 25-40% of the dose as the unchanged parent compound. 6-9% of an intravenous dose is eliminated in the feces. Overall, 60-65% of a dose is eliminated as glucuronide and sulfate metabolites.
Volume of Distribution
The volume of distribution of pindolol is approximately 2-3 L/kg.
Clearance
In otherwise healthy patients, the systemic clearance of pindolol is 400-500 mL/min. In patients with cirrhosis, the clearance of pindolol varies from 50-300 mL/min.
Pindolol is rapidly absorbed from the GI tract. Reported bioavailability ranges from 50-95%; bioavailability in uremic patients may be at the lower end of this range. Food does not reduce bioavailability but may increase the rate of GI absorption. Pindolol reportedly does not undergo substantial metabolism on first pass through the liver; ... only about 20% of an oral dose is metabolized on first pass. Peak plasma concentrations of 45-167 ng/ml are reached within 1-2 hr after administration of a single 20-mg dose. The extent of absorption may be decreased in patients with impaired renal function. The effect of pindolol on heart rate usually is seen within 3 hr and acute hemodynamic effects persist for 24 hr after administration of the drug.
McEvoy, G.K. (ed.). American Hospital Formulary Service - Drug Information 2003. Bethesda, MD: American Society of Health-System Pharmacists, Inc. 2003 (Plus Supplements)., p. 1778
Approximately 40-60% of pindolol is bound to plasma proteins. In healthy adults, the drug has an apparent volume of distribution of 1.2-2 l/kg; volume of distribution may be decreased by 50% in uremic patients. Pindolol is distributed into milk.
McEvoy, G.K. (ed.). American Hospital Formulary Service - Drug Information 2003. Bethesda, MD: American Society of Health-System Pharmacists, Inc. 2003 (Plus Supplements)., p. 1778
Elimination of pindolol appears to be a first-order process over a dose range of 5-20 mg. The drug has a plasma half-life of 3-4 hr in healthy adults. Plasma half-life increases to 3-11.5 hr in patients with renal failure, to 7-15 hr in geriatric patients, and varies from 2.5-30 hr in patients with hepatic cirrhosis. Approximately 60-65% of pindolol is metabolized in the liver to hydroxylated metabolites which are then excreted in urine as glucuronides and ethereal sulfates. In healthy adults, about 35-50% of the drug is excreted in urine unchanged; in patients with creatinine clearances less than 20 ml/min, less than 15% is excreted in urine unchanged.
McEvoy, G.K. (ed.). American Hospital Formulary Service - Drug Information 2003. Bethesda, MD: American Society of Health-System Pharmacists, Inc. 2003 (Plus Supplements)., p. 1778
Pindolol is rapidly and reproducibly absorbed (greater than 95%), achieving peak concentrations within 1 hr of drug administration ... The blood concentrations are proportional in a linear manner to the administered dose in the range of 5-20 mg ... Pindolol is only 40% bound to plasma proteins and is evenly distributed between plasma and red cells. The volume of distribution in healthy subjects is about 2 L/kg.
PDR; Physicians' Desk Reference Generics. 2nd Ed. Montvale, NJ: Medical Economics Co. p. 2489 (1996)
The polar metabolites are excreted with a half-life of approximately 8 hr and thus multiple dosing therapy ... results in a less than 50% accumulation in plasma. About 6%-9% of an administered intravenous dose is excreted by the bile into the feces.
PDR; Physicians' Desk Reference Generics. 2nd Ed. Montvale, NJ: Medical Economics Co. p. 2488 (1996)
30-40% of a dose of pindolol is not metabolized. The remainder is hydroxylated and subsequently undergoes glucuronidation or sulfate conjugation.
Pindolol reportedly does not undergo substantial metabolism on first pass through the liver; ... only about 20% of an oral dose is metabolized on first pass.

The beta-1 adrenoceptor is a G-protein-coupled receptor. Agonism of the beta-1 adrenoceptor allows the Gs subunit to upregulate adenylyl cyclase, converting ATP to cyclic AMP (cAMP). Increased concentrations of cAMP activate cAMP-dependant kinase A, phosphorylating calcium channels, raising intracellular calcium, increasing calcium exchange through the sarcoplasmic reticulum, and increasing cardiac inotropy. cAMP-dependant kinase A also phosphorylates myosin light chains, increasing smooth muscle contractility. Increased smooth muscle contractility in the kidney releases renin. Pindolol is a non-selective beta blocker. Blocking beta-1 adrenergic receptors in the heart results in decreased heart rate and blood pressure. By blocking beta-1 receptors in the juxtaglomerular apparatus, pindolol inhibits the release of renin, which inhibits angiotensin II and aldosterone release. Reduced angiotensin II inhibits vasoconstriction and reduced aldosterone inhibits water retention. Beta-2 adrenoceptors located in the kidneys and peripheral blood vessels use a similar mechanism to activate cAMP-dependant kinase A to increase smooth muscle contractility. Blocking of the beta-2 adrenoceptor relaxes smooth muscle, leading to vasodilation.
Class II antiarrhythmic, beta-adrenoceptor-blocking agents are membrane- depressant drugs that decrease the influx of sodium and calcium ions by reducing membrane-bound adenylate cyclase and cAMP. The reduction in cation transport lengthens depolarization by decreasing the amplitude and slope of the transmembrane potential. Beta-adrenoceptor-blocking agents also reduce myocardial contractility by decreasing calcium release from the sarcoplasmic reticulum (the influx of calcium couples excitation and contraction by initiating the release of calcium from the sarcoplasmic reticulum). Membrane-stabilizing activity enhances the reduction in myocardial contractility in overdose with these drugs in addition to producing a quinidinelike effect of QRS widening. A direct myocardial effect also leads to myocardial depression independent of beta-adrenergic blockade and membrane stabilization. /Class II beta-Blockers/

The principal physiologic action of pindolol is to competitively block beta-adrenergic receptors within the myocardium (beta1-receptors) and within bronchial and vascular smooth muscle (beta2-receptors). In addition to inhibiting access of physiologic or synthetic catecholamines to the beta-adrenergic receptors, pindolol causes slight activation of the beta-receptors, making the drug a partial beta-agonist. This intrinsic sympathomimetic activity of pindolol differs from the beta-agonist activity of epinephrine and isoproterenol in that the maximum beta-adrenergic stimulation that can be obtained with pindolol is less. Other beta-adrenergic blocking agents can block pindolol's intrinsic sympathomimetic activity. Pindolol also has been shown to possess membrane-stabilizing activity or a quinidine-like effect, but this occurs only at plasma concentrations well above those obtained therapeutically. Unlike atenolol and metoprolol, pindolol is not a beta1-selective adrenergic blocking agent; pindolol is a nonselective beta-adrenergic blocking agent, inhibiting both beta1- and beta2-adrenergic receptors.

By inhibiting myocardial beta1-adrenergic receptors, pindolol produces negative chronotropic and inotropic activity. Both of these actions are reversed somewhat, but not entirely, by the drug's partial agonist activity. The negative chronotropic action of pindolol on the sinoatrial node results in a decrease in sinoatrial node discharge and recovery time, thereby decreasing stress- and exercise-stimulated heart rate. Pindolol has a lesser effect on resting heart rate than do beta-adrenergic blocking agents that do not possess intrinsic sympathomimetic activity, usually decreasing resting heart rate only by about 4-8 beats/min or not at all ... Pindolol has a lesser effect on resting cardiac output than on that stimulated by exercise. The decrease in myocardial contractility, blood pressure, and heart rate produced by pindolol during stress and exercise leads to a reduction in myocardial oxygen consumption which accounts for the effectiveness of the drug in chronic stable angina pectoris. Pindolol is probably not effective in patients who develop angina at rest or at low exercise levels.

Unlike other beta-adrenergic blocking agents, pindolol does not consistently suppress plasma renin activity. In some studies, the drug has increased plasma renin concentrations and reversed the suppression of plasma renin induced by other beta-adrenergic blocking agents. Pindolol has not been shown to cause sodium retention.
