合适的固体载体为碳酸镁(magnesium carbonate)、硬脂酸镁(magnesiumstearate)、滑石(talc)、糖(sugar)、乳糖(lactose)、果胶(pectin)、葡聚糖(dextrin)、淀粉(starch)、凝胶(gelatin)、树胶(tragacanth)、甲基纤维素(methylcellulose)、羧酸甲基纤维素化钠(sodiumcarboxymethylcellulose)、低熔点蜡(a low melting wax)、可可油(cocoa butter)、以及类似物。为了制备栓剂,先融化低熔点蜡,例如甘油脂肪酸或可可油的混合物,并在其中藉由搅拌使活性成分均匀地分散。融化的均质混合物随后用方便尺寸的模具加以纯化,置放冷却,并因此使其固化。
液体形式药剂包括溶液、悬浮液以及乳液。作为范例,可提到用于非肠胃道注射之水或水-丙烯甘油溶液(water-propylene glycol solutions)。液体药剂亦可以液状聚乙烯甘油溶液(aqueous polyethylene glycol solution)配制为溶液。适合口服使用之液态溶液可如下制备:溶解活性成分于水中,添加需要的适合着色剂(colourants)、香料、安定与稠化剂(stabilizing and thickeningagents)。适合口服之液态悬浮液可如下制备:以黏性物质(viscous material)分散细致分离之活性成分于水中,亦即天然或合成的树胶(gums)、树脂(resins)、甲基纤维素、羧酸甲基纤维素化钠、以及其他已知的悬浮剂。
此外包括固体形式药剂,其预计在使用之前不久转换为液体药剂,以供口服或非肠道的给药。此类液体形式包括溶液、悬浮液与乳液。这些特别的固体形式药剂是最方便以单位剂量之形式提供,并用来提供为单个液体剂量单位。或者,足够的固体可被提供以便在转换后为液体形式,多个个别液体剂量可透过以注射器、茶匙、或其他容积容器或装置,来测量预先决定的液体形式药剂之容量而获得。当多个液体剂量被如此准备,较佳为于低温下维持该液体剂量的未使用部分,例如在冷藏下,以减缓可能的分解。固体形式药剂预计被转换为液体形式可能具有,除了活性材料以外,香料、着色剂、安定剂、缓冲液(buffers)、人工或天然甜味剂、分散剂、稠化剂、助溶剂(solubilising agents)、以及类似物。用于制备液体形式药剂之该液体可为水、等渗透压水(isotonic water)、乙醇、甘油(glycerine)、丙二醇(propyleneglycol)、以及类似物及其混合物。自然地,该液体之使用可依据给药路径而选用,例如,具有大量乙醇的液体药剂不适用于非肠胃道使用。
此处所使用之名词”食品(foodstuff)”、“食品补充物(food supplement)”、“饮料(beverage)”以及“饮料补充物(beverage supplement)”具有那些名词的通常意义,并不限于药理学上的药剂。其他组合物形式亦包括于本发明之范围中。例如,这些可包括纯化的或实质纯化的化合物,例如食品前驱物(foodstuff precursor),如可再成水合物之粉末(rehydratable powder),或饮料前驱物(beverage precursor),如可分散于水、牛奶或其他液体之粉末。
剂量可能依据患者之需要、欲治疗症状之严重性、以及所使用之化合物而变化。为特别的情势决定适当之剂量是在该领域之技术范围内。通常,治疗是由较少剂量开始,其少于化合物的最佳剂量。此后,剂量是少量增加,直到环境下之最佳效应已经达到。为了方便起见,如有需要,每日总剂量可以被分开并于一天的期间部分给药。
化学通式I之化合物有效剂量的大小,当然,是随着欲治疗之情形的严重性本身,以及特定的化学通式I之化合物及其给药路径而变化。适当剂量之选择是本领域普通技术人员之能力范围,并不需要过度的负担。通常,每日剂量的范围可为每公斤人类或非人类动物之体重从约10微克(μg)至约30毫克,较佳为每公斤人类或非人类动物之体重从约50微克至约30毫克,例如为每公斤人类或非人类动物之体重从约50微克至约10毫克,例如为每公斤人类或非人类动物之体重从约100微克至约30毫克,例如为每公斤人类或非人类动物之体重从约100微克至约10毫克,以及最佳为每公斤人类或非人类动物之体重从约100微克至约3毫克。
为了人类使用,该剂量可为方便地在每天约0.1毫克与约2公克之间,例如每天约0.1毫克与约1公克之间,较佳为每天约1毫克与200毫克之间,是依据特定应用和有效成分的效力。
除了化学通式I的一或多种化合物,该组合物亦可具有其他活性成分,例如环加氧酶抑制剂(cyclooxygenase inhibitors)、非固醇类消炎药物(non-steroidal anti-inflammatory drugs,NSAIDs)、周边止痛剂(peripheralanalgesic agents),例如氟苯水杨酸(diflunisal)与类似物。化学通式I之化合物对第二活性成分之重量比,可能被改变并且将依据每种成分的有效剂量。通常,每一个有效剂量都会被使用。因此,例如,当化学通式I之化合物与NSAID结合,化学通式I之化合物对NSAID之重量比将通常由约1000:1至约1:1000,较佳为约200:1至约1:200。化学通式I之化合物与其他活性成分之结合将通常亦在前述之范围内,但在每一个案中,每种活性成分的有效剂量应该被使用。
包括化学通式I之化合物的药学组合物,亦可具有作为第二活性成分之抗组织胺剂(antihistamine agents),例如西替利嗪(cetirizine)、二苯酚氢化物(diphenhyd rinate)、氯苯吡胺(chlorpheniramine)、异丙嗪(promethazine)以及类似物。或者,它们可包括前列腺素拮抗物(prostaglandin antagonists),例如那些如欧洲专利申请案第11,067号所揭露者,或血栓素拮抗物(thromboxane antagonists),例如那些如美国专利第4,237,160号所揭露者。它们亦可包含组氨酸脱羧酶抑制剂(histidine decarboxylase inhibitors),例如揭露于美国专利第4,325,961号之α-氟甲基组氨酸(α-fluoromethylhistidine)。该化学通式I之化合物亦可有利地与H1或H2-受体拮抗剂结合,例如甲氰咪胺(cimetidine)、雷尼替丁(ranitidine)、法莫替丁(famotidine)、替美斯汀(temelastine)、阿伐斯汀(acrivastine)、氯雷他定(loratadine)、西替利嗪、他齐茶碱(tazifylline)、氮卓斯汀(azelastine)、胺噻二唑(aminothiadiazoles)揭露于欧洲专利第81102976.8号,以及类似物,例如那些揭露于美国专利第4,283,408、4,362,736、4,394,508号,以及欧洲专利申请案第40,696号者。该医药组合物亦可包含K+/H+腺三磷酶抑制剂(K+/H+ATPase inhibitor),例如奥美拉唑(omeprazole),揭露于美国专利第4,255,431号,以及类似物。本段落中所引用之每个引用文献在此均加入作为本发明之引用文献。
生物学试验数据的讨论(Discussion of Biological Test Data)

起始物质(如反应方案中所示之化合物68)一开始是以氢化钠(NaH)及三甲基氯硅烷(TMSCI)于适当溶剂,例如四氢氟喃(THF)中处理。随后,烃化剂(alkylating agent),例如碘化烷(alkyl iodide),如反应方案3所示之碘化甲烷(methyl iodide,Mel),是于碱基,如碳酸钾(potassium carbonate)存在下使用。
当然,起始物质68亦可选择性地降低类似于反应方案1的最终步骤。为了完整,这个选择亦如反应方案3所示。
