Cefradine (eo hape e tsejoang e le cephradine), 7-[D-2-amino-2 (1,4cyclohexadien1-yl) acetamido] -3-methyl-8-0x0-5thia-l-azabicyclo[4.2.0] oct-2- ene-2-carboxylic acid monohydrate (111 ke semi-synthetic cephalosporin antibiotic. e sebelisoa ka molomo, intramuscularly, le intravenously. Sebopeho sa cephradine se tšoana le sa cephalexin, phapang e le 'ngoe feela e le lesale la litho tse tšeletseng.

Cephradine ke phofo e tšoeu ea kristale e nang le boima ba molek'hule ea 349.4[2]. Ho ile ha buisanoa ka motsoako oa cephradine[3]. Cephradine e qhibiliha ka bolokolohi ka li-solvents tse nang le metsi. Ke zwitterion, e nang le sehlopha sa alkaline amino le sehlopha sa acidic carboxyl. Mofuteng oa pH oa 3-7, cephradine e teng e le letsoai le ka hare[4]. Cephradine e tsitsitse bakeng sa 24 hr ho 25 "ka har'a pH ea 2-8. Kaha e tsitsitse mecheng ea litaba tsa acidic, ho na le tahlehelo e fokolang ea mosebetsi ka gastric fluid; tahlehelo e ka tlase ho 7% e tlalehiloe.[5].
Cephradine e hokahane ka mokhoa o fokolang ho liprotheine tsa serum ea motho. Setlhare se ne se le ka tlase ho 20% se tlameletsoe ho liprotheine tsa serum[4]. Ka har'a serum ea 10-12 pg/ml, 6% ea kakaretso ea lithethefatsi e ne e le ka har'a motsoako oa liprotheine. Thuto e 'ngoe[6]e fumane hore ka kakaretso ea 10 pg / ml, 28% ea lithethefatsi e ne e le boemong ba protheine; ka kakaretso ea 100 pg / ml, 30% ea lithethefatsi e ne e le boemong ba protheine.
