General description
Application
- 12-Hydroxy-octadecanoic acid polymer with α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl) has been used:
- in dissolving dexamethasone (DEX) to intraperitoneally inject the mice to test its grip strength to measure the muscle force
- in roflumilast preparation to treat rabbits and guinea pigs to study the mechanisms and pharmacological sensitivity of ozone-induced hypertussive responses
- to dissolve finerenone for oral application in in vivo-studies
