Inhaler Testing Dry Powder Inhalers (DPIs) As the name suggests, with a DPI the medication comes in the form of a dry powder, rather than a liquid. Typically, the active pharmaceutical ingredient(s) is mixed with a coarser excipient, such as lactose, to which it attaches. During aerosolisation the active is stripped from the carrier and inhaled whilst the carrier particles impact on the mouth and throat and are ingested. However, their relatively high cost and reliance on inhalation strength and duration are potential drawbacks. Passive The majority of DPIs are passive devices, that is to say...

Orally Inhaled & Nasal Drug Products Nebulisers Nebulisers convert a liquid into aerosol droplets to produce a respirable cloud suitable for inhalation. They are widely used at home and in hospital and require little or no coordination for effective use. Nebulisers are normally loaded with the drug before each treatment and usually operate continuously once loaded. The main advantage of nebulisers is that their use requires little or no coordination on the part of the patient. However, they tend to be cumbersome and require either compressed air or an electrical supply. Expense, inefficiency...

Inhaler Testing Soft Mist Inhalers (SMIs) Both MDIs and DPIs suffer from the same two inherent problems: low lung deposition (typically 5-20%) and dose variability (often due to patient difficulties in coordination or inspiration). SMIs (often known as “Inhalation Metered Sprays’’ or “Aqueous Droplet Inhalers”) actively aerosolise the liquid, forming a ‘soft mist’ to overcome these problems. These inhalers generally deliver a higher fine particle fraction than MDIs or DPIs. However, as with any multi-dose liquid system, microbial contamination can be a problem. SMIs do not use a propellant to...

Orally Inhaled & Nasal Drug Products Applications of OINDPs Pulmonary and nasal delivery offers a number of advantages compared to traditional oral and parenteral (subcutaneous injection) routes: Directly targets the site of action Rapid onset of drug action Drugs effective in relatively low doses Fewer side effects Avoids first pass metabolism Non-invasive administration Such drugs include treatments for diverse applications such as diabetes, erectile dysfunction, migraine, osteoporosis and for vaccine delivery. Orally Inhaled Drug Product Applications Orally inhaled drugs are becoming increasingly...

Inhaler Testing The ultimate responsibility for the safety, quality and efficacy of medicines and medical devices lies with the various national regulatory bodies designated to safeguard public health. At present, there are no worldwide standards that are specifically applicable to OINDPs. In the European Union, the responsibility for the regulation of medicines and medical devices lies with the European Medicines Agency (EMA) in the form of the Committee for Medicinal Products for Human Use (CHMP). The EMA was set up in 1995 to harmonise the work of existing national regulatory bodies in Europe....
