A 9,10alpha-dihydro derivative of [ergotamine]. Dihydroergotamine is used as an abortive therapy for migraines. Its use has largely been supplanted by triptans in current therapy due to the class's greater selectivity and more favourable side effect profile. Recent improvements have been made in the design of intranasal delivery devices allowing for greater delivery of dihydroergotamine solution to the vasculature-rich upper nasal cavity. The recently approved Precision Olfactory Delivery technology developed by Impel Neuropharma technology has correlated with an increase of 3-fold in Cmax and 4-fold in AUC despite the solution formulated at 75% of the strength of the existing intranasal product.
Cobicistat, marketed under the name Tybost (formerly GS-9350), indicated for treating infection with human immunodeficiency virus (HIV). Although it does not have any anti-HIV activity, cobicistat acts as a pharmacokinetic enhancer by inhibiting cytochrome P450 3A isoforms (CYP3A) and therefore increases the systemic exposure of coadministered agents that are metabolized by CYP3A enzymes. More specifically, cobicistat is indicated to increase systemic exposure of atazanavir or darunavir (once daily dosing regimen) in combination with other antiretroviral agents in the treatment of HIV-1 infection. Increasing systemic exposure of anti-retrovirals (ARVs) without increasing dosage allows for better treatment outcomes and a decreased side effect profile.
