The invention provides a pharmaceutical composition for intranasal administration comprising a salt of sumatriptan or a physiologically acceptable solvate thereof, an alkyl glycoside or saccharide alkyl ester and optionally at least one pharmaceutically acceptable excipient, wherein the said composition provides T.sub.max value of less than 30 minutes upon said administration. Other aspects and embodiments are contemplated and described.

The invention also provides a pharmaceutical composition for intranasal administration comprising a triptan, a pharmaceutically acceptable vehicle and a mucosal permeation enhancer, wherein upon said administration said composition provides a T.sub.max substantially equivalent to subcutaneous administration of said triptan. Other aspects and embodiments are contemplated and described.

In accordance with the present disclosure, macrocyclic compounds have been discovered that bind to PD-L1 and are capable of inhibiting the interaction of PD-L1 with PD-1 and CD80. These macrocyclic compounds exhibit in vitro immunomodulatory efficacy thus making them therapeutic candidates for the treatment of various diseases including cancer and infectious diseases.

A drug delivery system is provided for transdermally administering a psychedelic active agent to a subject to provide continuous microdose plasma levels of the active agent or a metabolite thereof during an extended drug delivery time period. The transdermal drug delivery system comprises a drug reservoir that houses a formulation containing the active agent, a combination of a solubilizer-type permeation enhancer and a plasticizer-type permeation enhancer, and a pH stabilizing agent. The pH stabilizing agent brings the pH of the formulation, at the system-skin interface, and/or within the skin as the active agent is transported across the skin from the skin surface to the bloodstream, to within 25% of the pKa of the active agent. Formulations and methods of use are also provided.

The present invention generally relates to artemisinin/dihydroartemisinin (DHA) derivatives, and their use for therapy, in particular cancer therapy. These tumor-homing artemisinin derivatives (THAD) comprise three moieties: an artemisinin/DHA or a derivative thereof, a heptamethine carbocyanine dye (HMCD) residue, and a linker that conjugates the HMCD dye residue to the artemisinin residue. The THAD include compounds wherein the linker is linked to one or two DHA residue(s) via one or more ether bonds, and wherein the linker is linked to two DHA residues via two bonds independently selected from ester, carbamate and thiocarbamate. The THAD of the invention provide improved growth inhibition of cancer cells. The present invention also relates to improved methods of cancer therapy wherein a THAD is administered to a cancer patient. In embodiments, one or more THAD may be co-administered in a coordinated administration schedule. Advantages of the THAD and their use include, among others, improved dose-response and/or efficacy. The invention also relates to new dyes, their drug conjugates, and processes of making them.

A combination of N-acetyl-L-cysteine, selenium in the form of selenomethionine and melatonin, and a medical product or pharmaceutical composition comprising such combination, useful for the treatment of a variety of diseases and conditions is described. The combination of N-acetyl-L-cysteine, selenium in the form of selenomethionine and melatonin is also useful for cosmetic treatment of skin and as an antibacterial agent.
