Betoptic S and Perforomist

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Using betaxolol ophthalmic together with formoterol may reduce the benefits of both medications, since they have opposing effects in the body. In addition, betaxolol ophthalmic can sometimes cause narrowing of the airways, which may worsen your breathing problems or trigger severe asthmatic attacks. You may not be able to use betaxolol ophthalmic if you have frequent asthma attacks or severe asthma or COPD (chronic obstructive pulmonary disease), or you may need a dose adjustment and more frequent monitoring of your lung function to safely use both medications. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact. Let your doctor know if you experience wheezing, shortness of breath, chest tightness, or other breathing difficulties during treatment with these medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

GENERALLY AVOID: Although cardioselective beta-blockers do not generally inhibit the bronchodilating effect of beta-2 adrenergic agonists, they may worsen pulmonary function in patients with asthma or other obstructive airway diseases. Cardioselective beta-blockers can occasionally precipitate acute bronchospasm in these patients, despite relative selectivity for beta-1 receptors in cardiac tissues. Presumably, beta-1 selectivity is dose-dependent and may be lost given a sufficient dose of the beta-blocker in susceptible patients. Other mechanisms may also be involved in bronchoconstriction that are unrelated to beta-2 blockade--for example, their effects on cholinergic M2 receptors and alpha-1 adrenoreceptors. Numerous single- and multiple-dose studies have been conducted in asthmatic and COPD patients with various cardioselective beta-blockers, including acebutolol, atenolol, bisoprolol, celiprolol, metoprolol, and nebivolol. Some reported no significant effects on pulmonary function or bronchodilator response to beta-2 agonists, while others reported some negative effects on pulmonary function and/or airway hyperresponsiveness. Overall, a meta-analysis of more than two dozen studies found that use of cardioselective beta-blockers in patients with mild to moderate reversible airway disease produced no adverse respiratory effects or decreased responsiveness to beta-2 agonists in the short term. A meta-analysis of 19 studies conducted in patients with COPD by the same group of investigators reported similar results. However, little data exist regarding their safety during chronic use or use in patients with severe respiratory disease. There have been reports of worsening asthma and bronchospasm in patients receiving cardioselective beta-blockers including betaxolol (both systemic and ophthalmic) and esmolol. Several studies have suggested enhanced bronchosparing effects of celiprolol over other cardioselective beta-blockers due to its partial beta-2 agonistic and alpha-2 blocking activities. However, one study found no difference between celiprolol and nebivolol. A few studies also suggested a lower degree of beta-1 selectivity for acebutolol compared to other cardioselective beta-blockers. The clinical significance is unknown.

MANAGEMENT: Beta-blockers, including those with relative cardioselectivity, should generally be avoided in patients with bronchospastic diseases. However, given their demonstrated benefit in such conditions as heart failure, myocardial infarction, cardiac arrhythmias and hypertension, cardioselective beta-blockers may be administered with caution to those who do not respond to or tolerate alternative treatment. The benefits generally outweigh the risks in patients with mild or moderate reactive airway disease that is well controlled on inhaled corticosteroids and beta-2 agonists, provided they have no prior history suggesting a predisposition to severe exacerbations. The dosage should start low, preferably in divided doses to avoid the higher plasma levels associated with longer dosing intervals, and titrated slowly according to therapeutic response and pulmonary function. Patients should be advised to contact their physician if they experience worsening of respiratory symptoms, which would warrant a reevaluation of the appropriateness of beta-blocker therapy. Cardioselective beta-blockers should be used with extreme caution, if at all, in patients prone to frequent exacerbations of their respiratory disease.
