ln Vitro |
Bopindolol, a non-selective antagonist of beta 1- and beta 2-adrenoceptors (ARs), has been found by pharmacological, molecular biological techniques and molecular modeling to have several unique properties. Bopindolol produces sustained blockade of beta 1- and beta 2-ARs, has intrinsic sympathomimetic as well as membrane stabilizing actions, inhibits renin secretion, and interacts with 5-HT receptors. Also, our recent molecular modeling studies identified possible interaction sites between bopindolol and beta-AR subtypes. The reviewed studies support our findings that bopindolol is non-selective for beta 1- and beta 2-ARs, has low affinity for beta 3-AR subtype and has pharmacological properties that are likely to be beneficial in the treatment of cardiovascular diseases [4].

ln Vivo |
Bopindolol (intravenous injection; 8, 16, and 32 μg/kg) is four times more effective than propranolol in dogs under anesthesia, and it inhibits isoprenaline-induced tachycardia in a dose-dependent manner[1]. The effects of dipindolol (0.3, 1 and 3 mg/kg; IP; single dosage) on heart rate and diastolic blood pressure are dose dependent[2].
1. Effects of bopindolol, a beta adrenoceptor antagonist with partial agonist activity, on the diastolic blood pressure and heart rate of pithed rats were compared with those of pindolol. 2. Both bopindolol and pindolol reduced the diastolic blood pressure (DBP) in pithed rats. Bopindolol (3.0 mg/kg) and pindolol (1.0 mg/kg) produced similar decreases in DBP of about 8 mmHg; thus pindolol had a 3-fold higher hypotensive potency when compared with bopindolol. 3. Both drugs also produced a dose-dependent decrease in heart rate. 4. Propranolol (5 mg/kg) had no antagonistic effect on the decrease in DBP produced by either bopindolol or pindolol. 5. These results suggest that both bopindolol and pindolol reduce DBP and heart rate in pithed rats through some mechanism independent of beta-adrenoceptors [2]. |
Animal Protocol |
Animal/Disease Models: Male Wistar rats (260-300 g)[2]
Doses: 0.3, 1 and 3 mg/kg Route of Administration: IP; single dosage Experimental Results: Produced dose dependent decreases in diastolic blood pressure, and the decrease of about 8 mmHg at 3 mg/kg. diminished the heart rate in a dose-dependent manner. |
ADME/Pharmacokinetics |
Bopindolol is a nonselective beta-adrenoceptor antagonist [corrected] with partial agonist activity which is used in the treatment of hypertension. The drug is rapidly metabolised to an active hydrolysed form. The antihypertensive effects of bopindolol 0.5 to 4 mg are sustained for more than 24 hours after once daily dosing, and the drug appears similar in efficacy to propranolol, metoprolol, atenolol, pindolol and slow release nifedipine in the treatment of mild to moderate forms of this disease. In limited trials bopindolol has also successfully reduced symptoms in patients with angina pectoris, anxiety and essential tremor. Thus, bopindolol is an effective and well-tolerated beta-adrenoceptor antagonist. [1]

Additional Infomation |
1-(tert-butylamino)-3-[(2-methyl-1H-indol-4-yl)oxy]propan-2-yl benzoate is a methylindole that is 2-methyl-1H-indol-4-ol in which the hydrogen of the hydroxy group is replaced by a 2-(benzoyloxy)-3-(tert-butylamino)propyl group. It is a methylindole, a secondary amino compound, an aromatic ether and a benzoate ester.
Bopindolol (INN) is an ester prodrug for the beta blocker [pindolol]. Drug Indication For the management of hypertension, edema, ventricular tachycardias, and atrial fibrillation. Mechanism of Action Bopindolol (as pindolol) non-selectively blocks beta-1 adrenergic receptors mainly in the heart, inhibiting the effects of epinephrine and norepinephrine resulting in a decrease in heart rate and blood pressure. By binding beta-2 receptors in the juxtaglomerular apparatus, Pindolol inhibits the production of renin, thereby inhibiting angiotensin II and aldosterone production and therefore inhibits the vasoconstriction and water retention due to angiotensin II and aldosterone, respectively. Pharmacodynamics Bopindolol is a prodrug of pindolol. Pindolol is a non-selective beta-adrenergic antagonist (beta-blocker) which possesses intrinsic sympathomimetic activity (ISA) in therapeutic dosage ranges but does not possess quinidine-like membrane stabilizing activity. Pindolol impairs AV node conduction and decreases sinus rate and may also increase plasma triglycerides and decrease HDL-cholesterol levels. Pindolol is nonpolar and hydrophobic, with low to moderate lipid solubility. Pindolol has little to no intrinsic sympathomimetic activity and, unlike some other beta-adrenergic blocking agents, pindolol has little direct myocardial depressant activity and does not have an anesthetic-like membrane-stabilizing action. |
