Unrecommended combinations
Antiarrhythmic drugs of the first class (for example, quinidine, disopyramide, lidocaine, phenytoin; flecainide, propafenone) with simultaneous application with bisoprolol may reduce AV conduction and contractility of the heart.
Blockers of "slow" calcium channels (BCCC) such as verapamil and to a lesser extent, diltiazem, with simultaneous application with bisoprolol may lead to a decrease in myocardial contractility and disruption AV conductivity.In particular, intravenous administration of verapamil to patients taking beta-blockers can lead to severe arterial hypotension and AV blockade.
Hypotensive agents of central action (such as clonidine, methyldopa, moxonidine, rilmenidine) can lead to a decrease in heart rate and a decrease in cardiac output, as well as to vasodilation due to a decrease in the central sympathetic tone. Abrupt withdrawal, especially before the abolition of β-blockers can increase the risk of developing "ricochet" arterial hypertension.
Combinations that require caution
Antiarrhythmic drugs of the III class (for example, amiodarone) can increase the violation AV conductivity.
The action of β-blockers for topical application (eg, eye drops for the treatment of glaucoma) can enhance the systemic effects of bisoprolol (lowering blood pressure, decreasing heart rate).
Parasympatomimetics with simultaneous use with bisoprolol may increase the disruption AV conductivity and increase the risk of developing a bradycardia.
Simultaneous use of the drug Bisoprolol with β-adrenomimetics (eg, isoprenaline, dobutamine) can lead to a decrease in the effect of both drugs. The combination of bisoprolol with adrenomimetics that affect β- and α-adrenergic receptors (for example, norepinephrine, epinephrine), can enhance the vasoconstrictor effects of these agents that arise with the participation of α-adrenergic receptors, leading to an increase in blood pressure. Similar interactions are more likely when using non-selective β-blockers.
Mefloquine with simultaneous application with bisoprolol may increase the risk of developing bradycardia.
Allergens used for immunotherapy, or allergen extracts for skin tests increase the risk of severe systemic allergic reactions or anaphylaxis in patients receiving bisoprolol.
Iodine-containing radiopaque diagnostic tools for intravenous administration increase the risk of anaphylactic reactions.
Phenytoin with intravenous administration, means for inhalation anesthesia (derivatives of hydrocarbons) increase the severity of cardiodepressive action and the likelihood of lowering blood pressure.
The effectiveness of insulin and hypoglycemic agents for oral administration may change with treatment with bisoprolol (masks the symptoms of developing hypoglycemia: tachycardia, increased blood pressure).
The clearance of lidocaine and xanthines (except theophylline) may decrease due to a possible increase in their concentration in the blood plasma, especially in patients with initially elevated clearance of theophylline under the influence of smoking.
Antihypertensive effect weaken non-steroidal anti-inflammatory drugs (NSAIDs) (sodium ion delay and blockade of prostaglandin synthesis by the kidneys), glucocorticosteroids and estrogens (sodium ion delay).
Cardiac glycosides, methyldopa, reserpine and guanfacine, blockers of "slow" calcium channels (verapamil, diltiazem), amiodarone and other antiarrhythmic drugs increase the risk of developing or worsening bradycardia, AV blockade, cardiac arrest and heart failure.
Nifedipine can lead to a significant reduction in blood pressure.
Diuretics, clonidine, sympatholytics, hydralazine and other antihypertensives can lead to excessive blood pressure lowering.
The effect of nondepolarizing muscle relaxants and the anticoagulant effect of coumarins during treatment with bisoprolol may be prolonged.
Tricyclic and tetracyclic antidepressants, antipsychotics (antipsychotics), ethanol, sedatives and hypnotics increase the inhibition of the central nervous system.
It is not recommended simultaneous use with MAO inhibitors (except for MAO B inhibitors) due to a significant increase in antihypertensive action. Simultaneous application can also lead to the development of hypertensive crisis. A break in treatment between taking MAO inhibitors and bisoprolol should be at least 14 days.
Unhydrated ergot alkaloids increase the risk of peripheral circulatory disorders.
Ergotamine increases the risk of peripheral circulatory disorders.
Sulfasalazine increases the concentration of bisoprolol in the blood plasma.
Rifampicin shortens the half-life of bisoprolol.
