Evaluation of instructions in patient information leaflets for the use of intranasal corticosteroid sprays: an observational study

OBJECTIVES: In this study, we analysed patient information leaflets (PILs) of intranasal corticosteroid sprays (INCS) of different manufacturers in the UK to determine if instructions for the use of INCS are complete and uniform. SETTING: PILs of all INCS of all manufacturers, available for patients in the UK, were collected from the British National Formulary website and the Medicines and Healthcare products Regulatory Agency website. All instructions in these PILs were analysed. PARTICIPANTS: We identified PILs of INCS from 21 different manufacturers, available for patients in the UK. RESULTS: We analysed the instructions for the use of INCS in 21 different PILs and there is large variation in the PIL instructions for the technique of using INCS across PILs. CONCLUSION: Complete and uniform instructions for the use of INCS are lacking in PILs for registered preparations in the UK. Structured and standardised instructions to be used by both professionals and patients are essential in order to optimise daily use of INCS

Pharmacology, particle deposition and drug administration techniques of intranasal corticosteroids for treating allergic rhinitis

This review presents an overview of the available literature regarding intranasal corticosteroids (INCs) for the treatment of allergic rhinitis (AR). Various treatment options exist for AR including INCs, antihistamines and leukotriene antagonists. INCs are considered to be the most effective therapy for moderate to severe AR, as they are effective against nasal and ocular symptoms and improve quality of life. Their safety has been widely observed. INCs are effective and safe for short-term use. Local adverse events are observed but generally well-tolerated. The occurrence of (serious) systemic adverse events is unlikely but cannot be ruled out. There is a lack of long-term safety data. INC may cause serious eye complications. The risk of INCs on the hypothalamic-pituitary-adrenal axis, on bone mineral density reduction or osteoporosis and on growth in children should be considered during treatment. Pharmacological characteristics of INCs (e.g. the mode of action and pharmacokinetics) are well known and described. We sought to gain insight into whether specific properties affect the efficacy and safety of INCs, including nasal particle deposition, which the administration technique affects. However, advances are lacking regarding the improved understanding of the effect of particle deposition on efficacy and safety and the effect of the administration technique. This review emphasizes the gaps in knowledge regarding this subject. Advances in research and healthcare are necessary to improve care for patients with AR

Nicotinic receptors

Regulation of normal or abnormal behaviour is critically controlled by the central serotonergic systems. Recent evidence has suggested that serotonin (5-HT) neurotransmission dysfunction contributes to a variety of pathological conditions, including depression, anxiety, schizophrenia and Parkinson’s disorders. There is also a great amount of evidence indicating that 5-HT signalling may affect the reinforcing properties of drugs of abuse by the interaction and modulation of dopamine (DA) function. This chapter is focused on one of the more addictive drugs, nicotine. It is widely recognised that the effects of nicotine are strongly associated with the stimulatory action it exhibits on mesolimbic DAergic function. We outline the role of 5-HT and its plethora of receptors, focusing on 5-HT2 subtypes with relation to their involvement in the neurobiology of nicotine addiction. We also explore the novel pharmacological approaches using 5-HT agents for the treatment of nicotine dependence. Compelling evidence shows that 5-HT2C receptor agonists may be possible therapeutic targets for smoking cessation, although further investigation is required.peer-reviewe

Inadequate quality of administration of intranasal corticosteroid sprays

In this study, we aimed to get insight into daily use of INCS and to determine if improvement of the technique is required. Patients and methods: A checklist, based on available patient information leaflets (PILs) and literature, was used to determine the participants’ application of the techniques used to administer INCS. These applied techniques were compared with steps described in PILs and recommended essential steps. Results: In the overall population (64 participants) four participants (6%) carried out all steps as described in the PIL and seven participants (11%) carried out all recommended essential steps. Conclusion: The technique used to administer INCS is inadequate. Uniform and generally applicable instructions are needed and patients using INCS should be guided better.
