Dorzolamide and timolol ophthalmic and Salbutamol
Determining the interaction of Dorzolamide and timolol ophthalmic and Salbutamol and the possibility of their joint administration.
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.
Consumer:Using timolol ophthalmic together with albuterol may reduce the benefits of both medications, since they have opposing effects in the body. In addition, timolol ophthalmic can sometimes cause narrowing of the airways, which may worsen your breathing problems or trigger severe asthmatic attacks. Timolol ophthalmic is normally not recommended if you have asthma, a history of asthma, or severe chronic obstructive pulmonary disease (COPD). Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact or are less likely to interact. 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.
Professional:GENERALLY AVOID: Beta-blockers may antagonize the effects of beta-2 adrenergic bronchodilators and precipitate acute, life-threatening bronchospasm in patients with asthma or other obstructive airway diseases. The mechanism involves increased airway resistance and reduced bronchodilation due to blockade of beta-2 adrenergic receptors. The interaction may also occur with ophthalmically applied beta-blockers, which are systemically absorbed and can produce clinically significant systemic effects even at low or undetectable plasma levels. Due to opposing effects on beta-2 adrenergic receptors, propranolol has been used in the treatment of albuterol overdose. Likewise, beta-2 adrenergic agonists may interfere with the pharmacologic effects of beta-blockers.
MANAGEMENT: Concomitant use of beta-2 adrenergic bronchodilators with beta-blockers, including ophthalmic formulations, should generally be avoided. If coadministration is required, a cardioselective beta-blocker (e.g., acebutolol, atenolol, betaxolol, bisoprolol, metoprolol, nebivolol) is usually preferred. Nevertheless, caution is advised and respiratory status should be closely monitored, as cardioselectivity is not absolute and larger doses of beta-1 selective agents may pose some of the same risks as nonselective agents. In general, nonselective beta-blockers are considered contraindicated in patients with obstructive airways disease.
