Description

TARIFNAME MORFIN VE MORFIN EKSTRAKTLARI NDA RETIKULIN IMPÜRITESININ SAFLIK VE STABILITE SPESIFIKASYONU OLARAK KULLANILMASI Morfin çok etkili agri kesici ilaç etken maddesidir. Opioidlerin tipik aktif maddesidir ve bu grubun prototipidir. Ham afyonda % 10-12 oraninda mevcuttur. Morfin ilaç olarak DSÖ'nün Temel Ilaçlar Listesi'nde yer almaktadir. DESCRIPTION IMPURITY OF RETIKULIN IN MORPHINE AND MORPHINE EXTRACTS USING PURITY AND STABILITY SPECIFICATION Morphine is a very effective painkiller active ingredient. It is the typical active ingredient of opioids and this is the prototype of the group. It is present at the rate of 10-12% in raw opium. WHO's morphine drug It is on the Essential Medicines List.

Morfin, narkotik agri kesiciler grubunda yer alan çok güçlü bir ilaçtir. Cerrahi operasyonlar, kanser agrilari, kalp krizi, uzun süren kronik agrilarin tedavisinde kullanilir. Morphine is a very powerful drug in the group of narcotic pain relievers. surgical operations, It is used in the treatment of cancer pain, heart attack, and long-lasting chronic pain.

Afyon (Opium), hashas bitkisinin kapsüllerinden elde edilen bir drogdur. Kapsüldeki opium miktari %0.2-0.8 arasinda degismekle beraber yapilan islah çalismalari neticesinde bu oran % l”e ulastigi belirtilmektedir. Ülkemizde ve dünyada tibbi amaçla kullanilan afyonun üretimi hashas (Papaver somniferum L.) bitkisinden yapilmaktadir. Hashastan afyon üretimi; 1974 yilina kadar hashas kapsüllerinin çizimi ile yapilirken daha sonra bu üretim sekli yasaklanmis ve daha güvenli bir yöntem olan çizilmemis kuru hashas kapsüllerinden alkaloit üretimine geçilmistir. Ülkemizde morfin üretimi en güvenilir sekilde Afyoniun Bolvadin ilçesinde kurulan Alkaloit Fabrikasmda yapilmaktadir. (ARSLAN ve ark. “Afyon (Opium) Alkaloitleri ve Önemi” Tarla Bitkileri Merkez Arastirma Enstitüsü Dergisi, 2008, 17 (1-2] 1 Afyon bilesiminde takriben %10 mortinj %5 kodein, %6 narkotin bulunabilmektedir. Morfinin afyondan çözelti halinde elde edilmesi, buharlastirma ve kalsiyum klorür çözeltisi ile yeniden çözme islemlerini gerektirir. Bu çözeltinin ayrilmasindan sonra sivi kisim birkaç kez buharlastirilir ve geride kalan morfin ve kodein kristalleri toplanir. Bunlar amonyak yardimiyla çözüldükten sonra yeniden kristallestirilir. Böylece morfin çözeltide kalan kodeinden ayrilmis olur. Morfin bir molekül su ile ignemsi kristaller halinde kristallesir. biri fenolik, digeri alkol grubu olmak üzere 2 tane hidroksil grubuna sahiptir. Fenolik grup metillenerek kodein elde edilir. Morfin etkin madde olarak tipta hidroklorür, sülfat, asetat, tartarat tuzlari halinde kullanilir. Opium (Opium) is a drug obtained from the capsules of the hash plant. opium in capsule Although the amount varies between 0.2-0.8%, this rate is % as a result of the improvement studies. It is stated that it reaches l. Production of opium used for medical purposes in our country and in the world It is made from the hashish (Papaver somniferum L.) plant. Opium production from Hashastan; 1974 While it was made with the drawing of hashish capsules until the year of, later this form of production was prohibited. and alkaloid production from scratch-free dry hashish capsules, which is a safer method. has been passed. Morphine production in our country is most reliable in Afyoniun Bolvadin district. It is made in the established Alkaloid Factory. (ARSLAN et al. “Opium (Opium) Alkaloids and Its Importance” Journal of Field Crops Central Research Institute, 2008, 17 (1-2] 1 In the opium composition, approximately 10% mortality, 5% codeine and 6% narcotine can be found. Morphine extraction from opium in solution, evaporation and reconstitution with calcium chloride solution. requires solving operations. After separation of this solution, the liquid part is washed several times. evaporated and the remaining morphine and codeine crystals are collected. These are with the help of ammonia recrystallized after dissolution. Thus, morphine was separated from the remaining codeine in solution. It is possible. Morphine crystallizes as needle-like crystals with one molecule of water. It has 2 hydroxyl groups, one of which is phenolic and the other is alcohol. phenolic group It is methylated to produce codeine. Morphine is used as an active ingredient such as hydrochloride, sulfate, acetate, used as tartrate salts.

Formül 1 Tip ve eczacilikta kullanilan dozaj formlari olarak morfin hidroklorür veya sülfat enjeksiyon; mg morphin içeren Sivi formu ve 10 mg morfin içeren supozituar formu vardir. Formula 1 Morphine hydrochloride or sulfate injection as dosage forms used in medicine and pharmacy; There is a liquid form containing mg morphine and a suppository form containing 10 mg morphine.
