Morphin
Morphin is the German-language spelling for morphine, the potent opioid analgesic derived from opium. In English-language contexts, the substance is commonly referred to as morphine. The English name morphine is widely believed to be derived from Morpheus, the Greek god of dreams, reflecting the drug’s powerful effects on consciousness and sensation. Historically, German texts have used the form Morphin, a reflection of older spelling conventions.
Morphin/morphine acts primarily on the central nervous system by binding to mu-opioid receptors, producing pain relief,
Because of its high potential for dependence and abuse, morphine is a controlled substance in most countries.
