Inhalation Carriers

Many drugs against lung diseases are administered through the lungs. The advantages are that lower doses can be used, fewer side effects are experienced and the medicine takes effect more quickly. This route of administration is increasingly used for systemic drug application, especially where injection is the only alternative. DPIs (dry powder inhalers) contain a powder consisting of an active ingredient and a carrier. The powder is packed in capsules or blisters containing one dose. This is called a single-dose system. Another possibility is that the powder is packed in a reservoir – the multi dose system. By far the most popular carrier is lactose. Toxicology data on this material after administration to the lung are favourable. Moreover, lactose is readily available and compatible with most active ingredients. Lactose has been used in DPIs for more than twenty years.
