The effectiveness of patches in the treatment of illnesses that have a chronic pattern compared with those with an acute presentation is yet to be elucidated. The effects of regional blood flow and permeability of skin, dose titrations, combination treatment with patches
and tablets, cumulative effects of long-term TDS use and drug interactions are yet to be fully understood. There Inhibitors,research,lifescience,medical are identifiable gaps in the literature on legal and ethical implications of use of transdermal patches in specific scenarios when limited capacity or lack of capacity to consent to treatment and issues around vulnerability can be an issue. In economically driven health markets, the cost of prescribed treatment is almost always debated. There are cost implications for developing Inhibitors,research,lifescience,medical transdermal formulations, such as the patented design and technology. Patches are more expensive compared with the parent oral drug: the primary care cost of rivastigmine (Exelon) 4.6 mg patches is twice as expensive compared with 4.5 mg of rivastigmine capsules [Joint Formulary Committee, 2011]. The availability
of cheaper generic formulations can deter pharmaceutical companies investing in TDS. The cost difference between TDS and generic oral formulations can also be a deterrent for prescribers who must LY2835219 concentration justify choosing Inhibitors,research,lifescience,medical a high-cost alternative of the same medication. With increasing emphasis on cost-effective drug therapy, having a wider range of research evidence such as patient and carer preferences, quality of life studies, RCTs with large sample sizes and economic evaluation studies will provide better Inhibitors,research,lifescience,medical clinical guidance on the use of TDS and provide the impetus to develop cost-effective solutions. Despite these uncertainties, TDS have opened opportunities to explore the capabilities of new drugs and use existing drugs to a new level in the treatment of psychiatric
disorders. TDS benefits over traditional Inhibitors,research,lifescience,medical methods are ease of titration, adherence to medications, optimal constant dosing and carer satisfaction. Increasingly, clinicians, policymakers and the public are becoming aware of the advantages of adherence to treatment and in maintaining wellbeing. The positive preliminary responses from patients and carers may bring focused attention to create an impact on targeted research and new ways of clinical practice in managing mental health disorders.
