Types of aerosolized medications
• Bronchodilators
• Antibiotics
• Antiviral
• Corticosteroids
• Others
7Gulf Thoracic Congress, 2015
Nebulized solution
• Continues treatment
• Less coordination required
• No PIF is required
• May be better aerosol output
• More availability

Why mixing?
• Save time
• Multiple patient ?!
• Save Resources
• synergistic effect ( 1+1 = 3)

Advantages of mixing
Long-acting inhaled therapy (beta-agonists, anticholinergics and steroids) for COPD: a network meta-analysis
Kayleigh M Kew1,*, Sofia Dias2, Christopher J Cates1 (2014)
“This network meta-analysis compares four different classes of long-acting inhalers for
people with COPD who need more than short-acting bronchodilators. Quality of life and lung function were improved most on combination inhalers (LABA and ICS) and least on ICS alone at 6 and at 12 months. Overall LAMA and LABA
inhalers had similar effects, particularly at 12 months. The network has demonstrated the benefit of ICS when added to LABA for these outcomes in participants who largely had an FEV1 that was less than 50% predicted, but the additional expense of combination inhalers and any potential for increased adverse events (which has been established by other reviews) require consideration. Our findings are in keeping with current National Institute for Health and Care Excellence (NICE) guidelines”

Advantages
The results of the indirect comparison support the hypothesis that budesonide/formoterol is associated with fewer pneumonia events than salmeterol/fluticasone in chronic obstructive pulmonary disease. The limitations of the analysis are that the results from a single study, TORCH, have a large bearing on the overall findings of the analysis, and that there is heterogeneity in the length and the dosing of the included studies, although it does not appear that heterogeneity affected the reported results. Another important limitation is the lack of predefined diagnostic standards for pneumonia in these studies.

Why mixing?
• Save time• Save Resources • Synergic effect• Multiple patient ?!• Better outcome

The ideal compatible mixture
• Proven to be physically compatible
• Proven to be chemically compatible
• Proven to have no change in aerosol output
• Proven to be clinically safe

incompatibility Chemical
incompatibility Physical incompatibility
• Change in color or odor• Change in pH • Haze or precipitation
• Change in the chemical characteristics• Agar diffusion assay• High performance liquid
chromatography (HPLC)• Ultraviolet spectroscopy
Lack of physical changes don’t rule out chemical changes

Mix safely, or don’t mix
• Refer to published research and data
• Refer to company recommendations
• Contact your hospital pharmacist
• Collaborate and study more medication and publish them
