Abstract
Description
본 발명은 신경병성 통증 치료용 약학 조성물에 관한 것이다.The present invention relates to a pharmaceutical composition for the treatment of neuropathic pain.
신경병성 통증(neuropathic pain)은 국제 통증 연구 협회(International Association for the Study of Pain)에 의해 "체성 감각 신경계의 병변 또는 질병으로 인한 통증"으로 정의된다. 성인의 7~8%의 삶의 질을 저하시키는 것과 관련이 있다. 그럼에도 불구하고 많은 환자들은 다양한 기전, 진단의 어려움, 비효과적인 치료 및 이러한 치료와 관련된 부작용으로 인해 신경병성 통증에 대한 적절한 치료를 받지 못하고 있다. 병용 요법에는 결정적인 등급 분류가 없지만 항경련제와 항우울제(신경병성 통증에 대한 1차 약물 모두)와의 병용 치료는 시너지 효과를 기대하는 의사에게 선택지가 될 수 있다. 이 접근법은 효능을 향상시키고 부작용을 감소시킨다. 또한, 신경병성 통증 병태 생리학에 기반한 적절한 약물 선택을 가능하게 하기 위해 새로운 표적의 식별에 상당한 관심이 있다.Neuropathic pain is defined by the International Association for the Study of Pain as "pain due to lesions or diseases of the somatosensory nervous system". It is associated with a reduced quality of life in 7-8% of adults. Nevertheless, many patients do not receive adequate treatment for neuropathic pain due to various mechanisms, difficulties in diagnosis, ineffective treatment, and side effects associated with these treatments. Although there is no definitive classification for combination therapy, combination therapy with an anticonvulsant and an antidepressant (both first-line drugs for neuropathic pain) may be an option for physicians expecting a synergistic effect. This approach improves efficacy and reduces side effects. In addition, there is considerable interest in the identification of novel targets to enable appropriate drug selection based on neuropathic pain pathophysiology.
칼슘 채널에 작용하는 항경련제인 프레가발린은 신경 전달 물질 방출을 억제한다. 포진 후 신경통, 당뇨병성 말초 신경병증, 척수 손상에서 효능이 입증되었다. 뚜렷한 신경화학적 특성을 가진 항우울제인 티아넵틴은 세로토닌 재흡수를 선택적으로 향상시킨다. 그러나 진통 효과에 관한 발표된 연구는 거의 없다. 항혈전제인 클로피도그렐은 간 대사에 의해 활성화되며 혈소판에서 퓨린성 P2Y12 수용체를 표적으로 삼는다. 특히 P2Y12 수용체 길항제는 병리학적 통증(예를 들어, 신경병성 또는 염증성 통증)과의 관계로 인해 최근 주목을 받고 있다.Pregabalin, an anticonvulsant drug that acts on calcium channels, inhibits neurotransmitter release. Efficacy has been demonstrated in postherpetic neuralgia, diabetic peripheral neuropathy, and spinal cord injury. Tianeptine, an antidepressant with distinct neurochemical properties, selectively enhances serotonin reuptake. However, there are few published studies on the analgesic effect. The antithrombotic drug, clopidogrel, is activated by hepatic metabolism and targets the purinergic P2Y12 receptor on platelets. In particular, P2Y12 receptor antagonists have recently received attention due to their relationship with pathological pain (eg, neuropathic or inflammatory pain).

5. 기계적 이질통(mechanical allodynia)의 평가5. Evaluation of mechanical allodynia
쥐를 철망 바닥이 있는 별도의 투명 용기에서 30분 동안 순응시키고, 케이지 아래에서 뒷발까지 calibrated von Frey 필라멘트로 테스트를 수행하였다. 8개의 von Frey 필라멘트(0.4, 0.7, 1.2, 2.0, 3.6, 5.5, 8.5, 15 g)를 뒷발의 발바닥 표면에 5초 동안 수직으로 순차적으로 누르고 필라멘트를 구부렸다. von Frey 필라멘트를 사용한 기계적 자극 후 빠른 발 회피 반응이 양성 결과(positive result)로 간주되었다. up and down 방법에 따라 양성 반응(positive reaction) 후에는 가벼운 필라멘트를 사용하고 음성 반응(negative reaction) 후에는 더 무거운 필라멘트를 사용했다. 첫 번째 양성 반응 후 일련의 5~6개의 실험이 수행되었다. 회피 반응(withdrawal reaction)을 나타내는 가장 가벼운 필라멘트는 발 회피 임계 값(paw withdrawal threshold)으로 정의되었다. 쥐가 Frey 필라멘트의 15 g 압력에서 철수 반응 없이 음성 반응하면 최대 값은 15 g으로 기록되었다.Rats were acclimated for 30 min in a separate transparent container with a wire mesh bottom, and the test was performed with calibrated von Frey filaments from under the cage to the hind paws. Eight von Frey filaments (0.4, 0.7, 1.2, 2.0, 3.6, 5.5, 8.5, 15 g) were sequentially pressed vertically on the plantar surface of the hind paw for 5 s and the filaments were bent. A rapid paw withdrawal response after mechanical stimulation with von Frey filaments was considered a positive result. According to the up and down method, a lighter filament was used after a positive reaction and a heavier filament was used after a negative reaction. A series of 5-6 experiments were performed after the first positive test. The lightest filament exhibiting a withdrawal reaction was defined as the paw withdrawal threshold. The maximum value was recorded as 15 g when rats responded negatively without withdrawal reaction at 15 g pressure of Frey filament.
6. 실험적 패러다임6. Experimental Paradigm
실험 당일(척수강내 배관 삽입 7일 후) 30분의 적응 시간을 겪은 쥐를 실험 및 대조군의 두 그룹으로 할당했다. 실험 약물은 무작위로 전달되었다. 대조군에서는 척수강내 식염수를 실험군과 동일한 부피로 전달하였다. 실험에 쥐는 한 번만 사용되었고 연구자는 사용된 약물이 무엇인지 모른 상태로 실험을 진행하였다. 신경병성 통증에 대한 척수강내 티아넵틴(30, 100, 300 ㎍), 클로피도그렐(300㎍) 및 프레가발린(0.3, 1, 3 ㎍)의 효과를 평가했다(그룹 당 5~7 마리의 쥐). 약물 주입 전에 기준 기계적 회피 임계 값(baseline mechanical withdrawal threshold)을 확인했다. 척수강내 약물 주입 후 15, 30, 60, 90, 120, 150 및 180 분에 발 회피 역치를 평가하였다. 최대 약물 용량은 신경학적 결함이 없던 예비 연구를 기반으로 결정되었다. 약물의 항통각 효과를 maximal possible effect(% MPE)의 백분율로 평가하였다.Rats that underwent an adaptation time of 30 minutes on the day of the experiment (7 days after intrathecal tube insertion) were assigned to two groups: experimental and control. Experimental drugs were delivered randomly. In the control group, intrathecal saline was delivered in the same volume as the experimental group. In the experiment, rats were used only once, and the researcher proceeded with the experiment without knowing what drug was used. The effects of intrathecal tianeptine (30, 100, 300 μg), clopidogrel (300 μg) and pregabalin (0.3, 1, 3 μg) on neuropathic pain were evaluated (5-7 rats per group). . A baseline mechanical withdrawal threshold was identified prior to drug infusion. Paw withdrawal thresholds were assessed at 15, 30, 60, 90, 120, 150 and 180 minutes after intrathecal drug injection. The maximum drug dose was determined based on a preliminary study in the absence of neurological deficits. The anti-nociceptive effect of the drug was evaluated as a percentage of the maximal possible effect (% MPE).

7. 약물 상호작용7. Drug Interactions
프레가발린과 티아넵틴 또는 클로피도그렐 사이의 약물 상호 작용을 평가하기 위해 Isobolographic 분석 및 고정 용량 분석을 수행했다(도 2). Isobolographic 분석은 약물의 등가 용량을 결정한다. 두 약물(프레가발린 및 티아넵틴)의 용량 반응 곡선에서 50 % 유효 용량(ED50) 값이 추정되었는데, 이는 MPE를 50% 감소시킨 것이다. 그 후, 개별 약물의 ED50을 기준으로 일정한 용량 비율로 두 약물의 조합 투여에 대한 용량 반응 곡선을 얻었다. 따라서, 티아넵틴 ED50 + 프레가발린 ED50, (티아넵틴 ED50 + 프레가발린 ED50)/2, (티아넵틴 ED50 + 프레가발린 ED50)/4 및 (티아넵틴 ED50 + 프레가발린 ED50)/8이 주입되었다. 그 후, 혼합 투여하는 경우의 각 약물의 ED50 값을 계산하였는데, 이는 두 약물 병용 투여에 대한 용량 반응 곡선에서 50% MPE를 나타내는 혼합물에 포함된 각 약물의 용량을 의미한다.Isobolographic analysis and fixed-dose analysis were performed to evaluate drug interactions between pregabalin and tianeptine or clopidogrel (Fig. 2). Isobolographic analysis determines the equivalent dose of the drug. A 50% effective dose (ED 50 ) value was estimated from the dose response curves of both drugs (pregabalin and tianeptine), which resulted in a 50% reduction in MPE. Then, a dose response curve was obtained for the combined administration of the two drugs at a constant dose ratio based on the ED 50 of the individual drugs. Thus, tianeptine ED 50 + pregabalin ED 50 , (tianeptine ED 50 + pregabalin ED 50 )/2, (tianeptine ED 50 + pregabalin ED 50 )/4 and (tianeptine ED 50 + pregabalin ED 50 )/4 and (tianeptine ED 50 + pregabalin ED 50 ) Gabalin ED 50 )/8 was injected. Then, the ED 50 value of each drug in the case of combined administration was calculated, which means the dose of each drug included in the mixture showing 50% MPE in the dose response curve for the combined administration of the two drugs.
Isobolograms는 각 약물의 ED50 값을 x 및 y 축에 각각 표시하여 표현했다(도 2). 두 점을 연결하는 선은 이론적인 부가적 작용 직선을 나타낸다. Isobologram 분석은 두 약물의 상호작용을 추론할 수 있는 방법으로, 혼합 투여시의 ED50가 부가적 작용 직선상에 위치하면 두 약물 간에 부가적 작용, 아래쪽에 위치하면 상승적 작용, 그리고 위쪽에 위치하면 길항적 작용 관계를 보인다고 말할 수 있다.Isobolograms were expressed by plotting the ED 50 values of each drug on the x and y axes, respectively (Fig. 2). The line connecting the two points represents the theoretical additive action line. Isobologram analysis is a method that can infer the interaction between two drugs. When the ED 50 of the mixed administration is located on the additive action line, it is an additive action between the two drugs, if it is located at the bottom, it is a synergistic action, and if it is located at the top, It can be said that there is an antagonistic action relationship.
또한 상호작용의 크기를 설명하기 위해 "총 량 분율 값(total dose fraction value)"이 사용되었다. 총 량 분율 값이 1에 근접하면 두 약물 간 부가 효과(additive effect), 1보다 작으면 상승 효과(synergistic effect), 그리고 1보다 크면 길항 효과(antagonistic effect)가 있다고 말할 수 있다.The “total dose fraction value” was also used to describe the magnitude of the interaction. When the total amount fraction value approaches 1, it can be said that there is an additive effect between the two drugs, when it is less than 1, there is a synergistic effect, and when it is larger than 1, it can be said that there is an antagonistic effect.
[수학식 2][Equation 2]
총 량 분율 값 = (약물 1 + 약물 2의 ED50) / (약물 1 단독의 ED50) + (약물 2 + 약물 1의 ED50) / (약물 2 단독의 ED50).Total dose fraction value = (
클로피도그렐만으로는 항이질통 효과가 없었기 때문에 프레가발린과 클로피도그렐의 상관 관계를 조사하기 위해 고정 용량 분석을 사용했다. 고정된 클로피도그렐 용량(300 ㎍)을 다양한 프레가발린 용량으로 척수강내에 주사했다.Because clopidogrel alone had no anti-allodynic effect, a fixed-dose assay was used to investigate the correlation between pregabalin and clopidogrel. A fixed dose of clopidogrel (300 μg) was injected intrathecally at various pregabalin doses.
8. 일반적인 행동8. General Behavior
프레가발린(3 ㎍), 티아넵틴(300 ㎍) 및 클로피도그렐(300 ㎍)의 최고 용량에서 행동 변화를 평가하기 위해 다른 쥐를 대상으로 추가 실험을 수행했다. 운동 기능에 대해 위치 반사(placing reflex), 내딛기 반사(stepping reflex) 및 정향 반사(righting reflex)를 평가했다. 각막 및 귓바퀴 반사는 각막 또는 외이도의 끈 자극에 의해 유도되었다. 행동 변화는 존재 또는 부재로 표시되었다.Additional experiments were performed in other mice to assess behavioral changes at the highest doses of pregabalin (3 μg), tianeptine (300 μg) and clopidogrel (300 μg). The placing reflex, stepping reflex, and righting reflex were evaluated for motor function. Corneal and pinna reflexes were induced by string stimulation of the cornea or external auditory meatus. Changes in behavior were indicated by presence or absence.
9. 통계 분석9. Statistical Analysis
모든 데이터는 평균 ± 표준편차로 표현된다. 용량-반응 결과는 사후 분석을 위해 Bonferroni comparison를 통한 one-way analysis of variance으로 분석되었다. 용량-반응 라인은 least-squares linear regression에 의해 맞춰졌다. ED50 및 95 % 신뢰 구간(CI)은 Tallarida와 Murray가 설명한 방법에 따라 계산되었다. 이론적 및 실험적 ED50 값의 차이는 t-test를 사용하여 조사되었다. P < 0.05는 통계적으로 유의한 것으로 간주되었다.All data are expressed as mean ± standard deviation. Dose-response results were analyzed by one-way analysis of variance through Bonferroni comparison for post-hoc analysis. Dose-response lines were fitted by least-squares linear regression. ED 50 and 95% confidence intervals (CI) were calculated according to the method described by Tallarida and Murray. Differences in theoretical and experimental ED 50 values were investigated using t-test. P < 0.05 was considered statistically significant.
결과result
촉각 이질통은 실험 쥐에서 L5-L6 척수 신경의 결찰 후에 유도되었다. 발 회피 역치는 < 4 g이었다. 각 약물의 최고 용량에서도 행동 변화가 관찰되지 않았다(즉, 프레가발린의 경우 3 ㎍, 티아넵틴의 경우 300 ㎍, 클로피도그렐의 경우 300 ㎍). 프레가발린과 티아넵틴은 둘 다 용량 의존적인 방식으로 기계적 회피 역치 값을 증가시켰다(도 3 및 도 4).Tactile allodynia was induced after ligation of L5-L6 spinal nerves in experimental mice. The paw avoidance threshold was <4 g. No behavioral changes were observed even at the highest dose of each drug (ie, 3 μg for pregabalin, 300 μg for tianeptine, and 300 μg for clopidogrel). Both pregabalin and tianeptine increased the mechanical avoidance threshold values in a dose-dependent manner ( FIGS. 3 and 4 ).
프레가발린과 티아넵틴의 1:1 비율은 isobolographic 분석에서 시너지 효과를 나타냈다. 실험 ED50 및 총 분율 값은 표 1에 나와있다. 고정 클로피도그렐 용량(300 ㎍)과 프레가발린을 함께 투여한 척수강내 병용은 프레가발린 단독의 발 회피 역치 값에 영향을 미치지 않았다. 하기 표 1은 척수 신경 결찰 쥐 모델에서 둘을 병용 투여한 경우의, 티아넵틴 및 프레가발린 각각을 척수강내에 투여한 경우에 비해 감소된 ED50 값과 이를 이용해 총 분율 값을 구한 것이다.A 1:1 ratio of pregabalin and tianeptine showed a synergistic effect in isobolographic analysis. Experimental ED 50 and total fraction values are given in Table 1. The combined intrathecal combination of a fixed dose of clopidogrel (300 μg) and pregabalin did not affect the paw avoidance threshold value of pregabalin alone. Table 1 below shows the reduced ED 50 value compared to the intrathecal administration of tianeptine and pregabalin, respectively, when the two were administered in combination in a rat model of spinal nerve ligation, and the total fraction value was obtained using the same.

두 약물의 척수강내 단독 투여 시, 티아넵틴의 ED50은 108.80 ㎍ (CI, 87.46 ~ 135.35 ㎍)이었고, 프레가발린의 ED50은 0.78 ㎍ (CI, 0.56 ~ 1.10 ㎍)이었고, 혼합 투여 시 티아넵틴의 ED50은 34.33 ㎍ (CI, 26.83 ~ 43.92 ㎍)이었고, 혼합 투여 시 프레가발린의 ED50은 0.24 ㎍ (CI, 0.19 ~ 0.31 ㎍)이었다. 이 수치를 이용하여 구한 총 분율 값(total dose fraction value)은 0.63으로 1보다 작으며, 이는 두 약물 간에 상승 효과(synergistic effect)가 있다는 것을 나타낸다.When both drugs were administered intrathecally alone, the ED 50 of tianeptine was 108.80 μg (CI, 87.46 ~ 135.35 μg), and the ED 50 of pregabalin was 0.78 μg (CI, 0.56 ~ 1.10 μg), and when administered in combination, thia The ED 50 of neptine was 34.33 μg (CI, 26.83 ~ 43.92 μg), and the ED 50 of pregabalin was 0.24 μg (CI, 0.19 ~ 0.31 μg) when administered in combination. The total dose fraction value obtained using this number is 0.63, which is less than 1, indicating that there is a synergistic effect between the two drugs.
