Pulmonary drug delivery is becoming a favored route for administering drugs to treat both lung and systemic diseases. Examples of lung diseases include asthma, cystic fibrosis and chronic obstructive pulmonary disease (COPD) as well as respiratory distress syndrome (ARDS) and pulmonary fibrosis. Special respiratory drugs are administered to the lungs, using an appropriate inhaler device. Next to the pressurized metered-dose inhaler (pMDI), the dry powder inhaler (DPI) is a frequently used device because of the good drug stability and a minimal need for patient coordination...

BACKGROUND: Pressurized metered-dose inhalers (pMDIs) should be shaken before use to prevent creaming or sedimentation of the drugs in solution; however, data published on this topic are limited, and it is rarely specified how soon after shaking the device should be actuated. Delays between shaking and firing the pMDI have previously been shown to cause significant inhomogeneity in delivered dose. We studied the effect of various shake-fire delays on the drug delivered from five commercially available pMDIs commonly prescribed for asthma and chronic obstructive pulmonary disease to assess the potential variability in delivered dose...

REVIEW
Wouter H van Geffen, W R Douma, Dirk Jan Slebos, Huib A M Kerstjens
BACKGROUND: Bronchodilators are a central component for treating exacerbations of chronic obstructive pulmonary disease (COPD) all over the world. Clinicians often use nebulisers as a mode of delivery, especially in the acute setting, and many patients seem to benefit from them. However, evidence supporting this choice from systematic analysis is sparse, and available data are frequently biased by the inclusion of asthma patients. Therefore, there is little or no formal guidance regarding the mode of delivery, which has led to a wide variation in practice between and within countries and even among doctors in the same hospital...

INTRODUCTION: Incorrect use of inhaler devices by patients with asthma is common and can adversely affect clinical outcomes. Devices that are straightforward to use are less likely to result in dosing errors and can improve patients' satisfaction with therapy and adherence. A novel dry-powder formulation of the rescue bronchodilator albuterol (salbutamol) administered using a multidose dry-powder inhaler (mDPI; RespiClick™) has recently been approved in the USA. AREAS COVERED: Studies on the albuterol mDPI were identified in searches of PubMed and www...

BACKGROUND: The use of chlorofluorocarbons (CFCs) has contributed to the depletion of the stratospheric ozone layer resulting in serious health concerns. Ipratropium bromide/salbutamol sulphate CFC-pressurized metered-dose inhalers (IB/SAL-CFC pMDI) have been in widespread use for many years without any apparent ill consequences. This combination has now been reformulated using the hydrofluoroalkane (HFA) propellant. This study sought to establish the clinical noninferiority of a new HFA-containing IB/SAL pMDI to the conventional IB/SAL-CFC pMDI in subjects with mild/moderate COPD...

BACKGROUND: Unambiguously for inhaled products, PK measures are best suited for ensuring that the total systemic exposure is equivalent for two products but cannot provide regional information about lung deposition and structural changes. Functional respiratory imaging (FRI) has been demonstrated to be sensitive for distinguishing small but imperative differences related to a single treatment. METHODS: In this study FRI is used in 16 asthmatic patients to assess equivalence in regional deposition for two products (fluticasone/salmeterol, test and reference) by directly measuring regional functional and structural changes within the lungs following its administration...

BACKGROUND: Pressurized metered-dose inhalers (pMDIs) are commonly used to administer medication to patients suffering from chronic lower respiratory tract diseases such as asthma. Inhaling medication directly from a pMDI can prove difficult for some patients and, as a result, add-on devices (or spacers) have been designed to aid in the delivery of medication. Although spacers increase the percentage of medication that reaches the patient, medication will also nonsymmetrically deposit on the walls of the device and will be lost to the device itself...
