Description
Technical field
The invention belongs to pet pharmaceutical technology field, more particularly, to a kind of dog cat terbinafine HCl flavor piece and its
Preparation process.
Background technique
In veterinary clinic practice, dog cat fungoid disease is a kind of very common and multiple disease, and average attack rate is about
For 10%-40%, the course of disease is long, it is difficult, easy to recur to cure, and can mutually pass on from one to another between animal and animal, person to person, people and animal
Broadcast, cause serious public health problem, terbinafine HCl has a broad antifungal spectrum, sterilizing power is strong, minimum bactericidal concentration (MFC) with
Minimum inhibitory concentration (MIC) is almost equal, and particularly sensitive to dermatophyte, clinical application is increasingly extensive, list since 1991 with
Come, through nearly 20 years Human clinical's practical proofs, curative effect really, adverse reaction is few, and toxicity is low, is that extraordinary one kind is antimycotic
Medicine, but on the one hand due to its taste hardship, dog cat is reluctant to take, at present veterinary clinic based on spray and ointment external application, but
It is very poor to deep skin and enteron aisle, ear's fungal infection effect；On the other hand, the terbinafine HCl piece of existing dog cat
Stability is poor, causes blood medicine effective concentration low, and cure time is long, and the time for needing to take drugs and metering are larger, therefore animal doctor
Clinic needs the Oral antifungal agents object that a kind of dog cat is willing to accept and bioavilability is high.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of bitter taste for effectively reducing raw medicine, blood medicine effective concentration times to grow
Dog cat terbinafine HCl flavor piece.
The present invention also provides a kind of preparation processes of dog cat terbinafine HCl flavor piece.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: a kind of dog cat terbinafine HCl flavor
Piece, constituent proportion count by weight percentage are as follows: terbinafine HCl piece 5%-10%, polymeric complexing agent
25%-50%, agreeable to the taste dose of 5%-10%, polyacrylic resinⅡ type 10%-20%, flavoring agent 50%-70% and magnesium stearate
2%-5%.
Further, the polymeric complexing agent is 15-hydroxy polyethylene glycol stearate or polyvinylpyrrolidone.
Further, described agreeable to the taste dose is stearic acid, tristerin or pure butter.
Further, the flavoring agent includes one of lactose, chicken meal, powdered beef and sodium carboxymethyl starch or more
Kind.
A kind of preparation process of dog cat terbinafine HCl flavor piece, comprising the following steps:
(1) suspension is made in addition terbinafine HCl piece after weighing polymeric complexing agent heating fusing；
(2) it after by agreeable to the taste dose of heating fusing in the liquid of clear, is added in suspension, is protected at 90 DEG C -100 DEG C
Temperature is spraying, and freeze-drying obtains the microcapsule granule of 40 mesh；
(3) polyacrylic resinⅡ type is dissolved with dehydrated alcohol, the microcapsule granule in step (2) is placed in fluidized bed and is carried out
Bottom spray is coated to obtain tasteless terbinafine HCl particle；
(4) it takes the tasteless terbinafine HCl particle in step (3) that flavoring agent is added, mixes, softwood is made, cross 20 meshes
Granulation after dry, crosses 24 mesh sieves, and magnesium stearate is added and mixes, tabletting.
Compared with prior art, the present invention has the advantage that is with beneficial effect:
The present invention carries out macromolecule complexing using polymeric complexing agent and terbinafine HCl piece, improves hydrochloric acid spy and compares naphthalene
The stability of fragrant piece, effective extended period blood medicine effective concentration time reduce the number and medication quantity of the medication of dog cat, while benefit
Technology is covered with solid dispersion packet and adds agreeable to the taste dose and flavoring agent, can be effectively reduced the bitter taste of raw medicine, is more willing to dog cat
It takes.

The pharmacokinetics for having carried out dog to the long-acting flavor piece of the terbinafine HCl produced by the above implementation method is ground
Study carefully.8 healthy beasle dogs are taken to be randomly divided into A and bis- groups of B (every group 4, male and female is fifty-fifty), single dose intravenous hydrochloric acid spy compares naphthalene respectively
Fragrant sterile solution 10mg/kg and the long-acting flavor piece 10mg/kg of single oral dose terbinafine HCl and take general technology hydrochloric acid
Terbinafine.
Terbinafine content is tested and analyzed using HPLC UV detector in blood plasma, and the actual measurement blood medicine of Terbinafine is dense
Degree-time data use WinNonlin5.2 editions pharmacokinetic analysis softwares, calculate pharmacokinetic parameter, as a result as follows:
Bolos intravenous administration Terbinafine T1/2 β be (15.158 ± 8.558) h, Tmax and Cmax be respectively (0.083 ±
0.000) h and (3.334 ± 0.185) μ g/mL, MRT are (2.443 ± 1.132) h, and AUC0~t is (1.803 ± 0.374) μ g
H/mL, Vd are (49.778 ± 25.594) L/kg, and CLB is (2.415 ± 0.577) L/ (kgh)；
After the long-acting flavor piece piece of dog single oral dose 10mg//kg bw terbinafine HCl, Terbinafine T1/ in dog body
2 β are (22.150 ± 10.557) h；Tmax(1.875±0.791)h；Cmax is (0.157 ± 0.087) μ g/ml；MRT is
(5.019±1.591)h；AUC0~t is (1.094 ± 0.588) μ gh/mL；It is estimated by AUC0~t, absolute bioavailability
(F0~t) is (16.589 ± 11.495) %；
Terbinafine HCl common process piece, Terbinafine T1/2 β in dog body is (16.250 ± 6.557) h；Tmax
(1.945±0.781)h；Cmax is (0.196 ± 0.102) μ g/ml；MRT is (5.310 ± 1.528) h；AUC0~t is
(1.066±0.548)μg·h/mL；By AUC0~t estimate, absolute bioavailability (F0~t) be (19.589 ±
13.463) %.
