This is associated with poorer asthma control. Cognitive behavioral therapy may improve quality of life, asthma control, and anxiety levels in people with asthma.Improving peoples knowledge about asthma and using a written action plan has been identified as an important component of managing asthma. Providing educational sessions that include information specific to a persons culture is likely effective. More research is necessary to determine if increasing preparedness and knowledge of asthma among school staff and families using home-based and school interventions results in long term improvements in safety for children with asthma. School-based asthma self-management interventions, which attempt to improve knowledge of asthma, its triggers and the importance of regular practitioner review, may reduce hospital admissions and emergency department visits. These interventions may also reduce the number of days children experience asthma symptoms and may lead to small improvements in asthma-related quality of life. More research is necessary to determine if shared-decision-making is helpful for managing adults with asthma or if a personalized asthma action plan is effective and necessary. Some people with asthma use pulse oximeters to monitor their own blood oxygen levels during an asthma attack. However, there is no evidence regarding the use in these instances. Lifestyle modification
Avoidance of triggers is a key component of improving control and preventing attacks. The most common triggers include allergens, smoke (from tobacco or other sources), air pollution, non selective beta-blockers, and sulfite-containing foods. Cigarette smoking and second-hand smoke (passive smoke) may reduce the effectiveness of medications such as corticosteroids.
Netarsudil, sold under the brand name Rhopressa among others, is a medication for the treatment of glaucoma. In the United States, in December 2017, the Food and Drug Administration (FDA) approved a 0.02% ophthalmic solution for the lowering of elevated intraocular pressure in people with open-angle glaucoma or ocular hypertension. The European Medicines Agency approved it in 2019 for the same uses under the brand name Rhokiinsa.The FDA considers it to be a first-in-class medication. Contraindications
Netarsudil has no contraindications apart from known hypersensitivity to the drug. Adverse effects
The most common side effects are hyperaemia (increased blood flow associated with redness, in 51% of patients) in the conjunctiva, cornea verticillata (drug deposits in the cornea, in 17%), and eye pain (in 17%). All other side effects occur in fewer than 10% of people. Hypersensitivity reactions occur in fewer than 1%. Overdose
Overdosing netarsudil is unlikely because concentrations in the body are so low that they are generally not detectable. Interactions
No interaction studies have been done. The European label recommends to apply other eye drops at least five minutes before, and eye ointments at least five minutes after netarsudil drops. Pharmacology
Mechanism of action
This drugs mechanism of action is not entirely clear. It inhibits the enzyme rho kinase. This appears to increase outflow of aqueous humor through the trabecular meshwork, and also to reduce pressure in the veins of the episcleral layer. The drug also inhibits the norepinephrine transporter. Pharmacokinetics
After instillation into the eye, netarsudil is cleaved by esterases in the cornea to AR-13503, which is the active metabolite.
