Abstract
Description
technical field
[0001] The invention relates to pharmaceutical preparation technology, more specifically to a pharmaceutical composition for transdermal administration of morphine-6-glucuronide and its preparation method and application. Background technique
[0002] Morphine-6-glucuronide [Morphine-6-glucuronide, referred to as M6G, as shown in formula (I), is the active metabolite of morphine in vivo. Morphine as an opioid is currently the most widely used narcotic analgesic for the treatment of moderate to severe pain, but studies have shown that it is not morphine itself that acts as an analgesic. Morphine is mainly combined with glucuronide in the liver and produces two metabolites: morphine-3-glucuronide (M3G) and morphine-6-glucuronide (M6G). M6G can bind to opioid receptors, and animal experiments show that its analgesic effect is stronger than that of morphine, and its adverse reactions are milder. M3G has a low affinity with opioid receptors and has no analgesic ...
Examples
Embodiment 1
[0066] Embodiment 1 Transdermal patch preparation of morphine-6-glucuronide hydrobromide
[0067] (1) Micronize 5 g of morphine-6-glucuronide hydrobromide, 2 g of povidone (PVP-S630) and 0.1 g of magnesium stearate, mix well to obtain a physical mixture, and add polyethylene glycol (Molecular weight 2000) 2.9g;
