Review Comparative StudyA review of clinical safety data for sumatriptan nasal powder administered by a breath powered exhalation delivery system in the acute treatment of migraine.
AVP-825 (sumatriptan nasal powder) is an FDA-approved intranasal medication delivery system containing low-dose sumatriptan powder for acute treatment of migraine with or without aura in adults. AVP-825 utilizes unique nasal anatomy features to avoid limitations of other intranasal delivery methods. Areas covered: Literature search terms: 'AVP-825', 'sumatriptan nasal powder', 'intranasal sumatriptan', 'sumatriptan safety', 'sumatriptan acute migraine'. ⋯ AVP-825 has the advantage of early efficacy onset associated with faster absorption at a lower delivered dose than liquid nasal spray or oral formulations. AVP-825 provided earlier efficacy (within 30 min) vs. 100 mg oral sumatriptan and similar sustained efficacy. AVP-825 offers the benefits of a non-oral, low-dose, tolerable acute migraine medication.

ReviewA narrative review of the safety concerns of deprescribing in older adults and strategies to mitigate potential harms.
As with prescribing or continuing medications, deprescribing brings with it the potential for harm as well as benefit. Uncertainty and avoidance of harm has been reported as a barrier to deprescribing in practice and may contribute to continuation of inappropriate medications. ⋯ More research is needed into the safety concerns of deprescribing, however, avenues exist during drug development and post-marketing surveillance to gain knowledge on this topic. Questions remain about when it is suitable to discontinue certain medications/medication classes and there is uncertainty about the harms and benefits of both medication continuation and discontinuation in complex older adults.
