摘要： Oral formulations and method of formulating photosensitive agents for oral administration during photodynamic therapy (PDT) and Antimicrobial photodynamic therapy (APDT) treatment are presented. The oral formulated photosensitizers show increased solubility and permeability, thus improving the bioavailability of photosensitizers at the treatment site. An orally administered photosensitizer is suitably formulated for mucosal adhesion and absorption via gastrointestinal mucosal membranes. Oral formulation provided herein use lipids and known proteins as carriers for photosensitizers by oral route. Carriers for encapsulating preselected photosensitizers include conventional liposomes, pegylated liposomes, nanoemulsions, nanocrystrals, nanoparticles, fatty emulsions, lipidic formulations, hydrosols, SMEDDS, Alpha-Feto protein (AFP), and Bovine-Serum-Albumin (BSA), fatty emulsions, hot-melt-extrudates and nanoparticles. The oral formulation, in case of a hydrophobic photosensitizer in the present invention, is stabilized using suitable surfactants/solubilizers thus preventing aggregation of the drug in the stomach and until it is absorbed in the duodenum and the small intestine. Oral formulations can be administered in the form of liquid, capsule, tablet, powder, paste or gel. Formulated drugs can be administered orally as one single dose or in multiple doses before administering PDT. In one embodiment Temoporfin (m-THPC) is used as a photosensitizer in the oral formulations. Temoporfin like many hydrophobic photosensitizers are especially suitable to be administered orally because there is no known enzyme system in the mammalian body which can metabolize Temoporfin or similar photosensitizers. Temoporfin can reach the blood system unchanged and fully active after absorption of the formulation in the gastrointestinal tract.
摘要翻译：提出了在光动力治疗（PDT）和抗微生物光动力疗法（APDT）治疗中配制口服光敏剂的口服制剂和方法。口服配制的光敏剂显示增加的溶解度和渗透性，从而提高光敏剂在治疗部位的生物利用度。口服给药的光敏剂适于配制用于通过胃肠粘膜进行粘膜粘附和吸收。本文提供的口服制剂通过口服途径使用脂质和已知蛋白质作为光敏剂的载体。用于封装预选光敏剂的载体包括常规脂质体，聚乙二醇化脂质体，纳米乳剂，纳米胶体，纳米颗粒，脂肪乳剂，脂质制剂，水溶胶，SMEDDS，α-铁蛋白（AFP）和牛血清白蛋白（BSA），脂肪乳剂，热熔融挤出物和纳米颗粒。在本发明的疏水性光敏剂的情况下，使用合适的表面活性剂/增溶剂稳定口服制剂，从而防止药物在胃中的聚集，直到其被吸收到十二指肠和小肠中。口服制剂可以以液体，胶囊，片剂，粉末，糊剂或凝胶的形式施用。配制药物可以在给予PDT之前以一次剂量或多次剂量口服给药。在一个实施方案中，Temoporfin（m-THPC）用作口服制剂中的光敏剂。类似于许多疏水性光敏剂的Temoporfin特别适合于口服给药，因为哺乳动物体内没有已知的可以代谢Temoporfin或类似光敏剂的酶系统。 Temoporfin可以在胃肠道吸收制剂后达到血液系统不变和充分活性。

摘要： Pharmaceutical pegylated liposomal formulations for photodynamic therapy are presented. The pegylated liposomal formulation provides therapeutically effective amounts of the photosensitizer for intravenous administration. At least one of the phospholipids in the liposomes has been linked with poly ethylene glycol (PEG) as an integral part of the phospholipids. The formed pegylated liposomes contain the hydrophobic photosensitizer within the lipid bilayer membrane. Pegylation of liposomes carrying the hydrophobic photosensitizer helps to maintain the drug level within the therapeutic window for longer time periods and provides the drug a longer circulating half life in vivo. Further the pegylated formulation of hydrophobic photosensitizers shows improved pharmacokinetics over standard non-liposomal formulations thus enhancing the efficacy of PDT with the pegylated liposomal formulations.
摘要翻译：提出了用于光动力学治疗的药物聚乙二醇化脂质体制剂。聚乙二醇化脂质体制剂提供治疗有效量的用于静脉内施用的光敏剂。脂质体中的至少一种磷脂已经与作为磷脂的组成部分的聚乙二醇（PEG）连接。形成的聚乙二醇化脂质体在脂质双层膜内含有疏水性光敏剂。携带疏水性光敏剂的脂质体的聚乙二醇化有助于在治疗窗口内维持更长时间的药物水平，并使药物在体内延长循环半衰期。此外，疏水性光敏剂的聚乙二醇化制剂显示与标准非脂质体制剂相比改善的药物代谢动力学，从而增强PDT与聚乙二醇化脂质体制剂的功效。

摘要： Pharmaceutical liposomal formulations are described for photodynamic therapy comprising a, hydrophobic porphyrin photosensitizer, a monosaccharide and one or more synthetic phospholipids, which are stable in storage especially through freeze-drying process. The liposomal formulations provide therapeutically effective amounts of the photosensitizer for intravenous administration. In particular derivatives of chlorins and bacteriochlorins, such as temoporfin, are, hydrophobic photosensitizers whose efficacy and safety are enhanced by such liposomal formulations. The formulation can be efficiently freeze-dried preserving the size of the liposomal vehicles, and the content of a therapeutically effective amount of the photosensitizer, due to the selection of phospholipids and monosaccharides. The invention also relates to liposome compositions formed upon reconstitution with an aqueous vehicle. The freeze-dried formulation upon reconstitution with a suitable aqueous vehicle forms liposomes that are useful for intravenous administration.

摘要： Pharmaceutical liposomal formulations for photodynamic therapy are presented, which are stable in storage as liquid formulations, comprise a hydrophobic photosensitizer and one or more synthetic phospholipids. The liposomal formulations provide therapeutically effective amounts of the photosensitizer for intravenous administration. The formed liposomes contain the hydrophobic photosensitizer within the lipid bilayer membrane. In the present formulation the size of the liposomal vehicles and their content of a therapeutically effective amount of the photosensitizing agent remain unchanged over storage times of a year or more, thus making the liquid formulations commercially viable. Being stable in the liquid state also makes them easy to store, and easier to use for doctors and patients. They can be prepared in a ‘factory setting’ delivered to practitioners in a liquid state and be available for use in PDT related treatments as called for by the practitioners' patient needs.

摘要： A pharmaceutical liposomal formulation for photodynamic therapy comprising a non-polar porphyrin photosensitizer and one or more phospholipids, which are stable in storage without requiring freeze-drying is described. The liposomal formulation provides therapeutically effective amounts of the photosensitizer for intravenous administration. The phospholipids may be modified by pegylation, i.e. they contain poly ethylene glycol as an integral part of the phospholipids. The formed liposomes contain the non-polar photosensitizer within the membrane and are useful for the combined targeting of a non-polar photosensitizer and a second polar substance. When a formulation includes the presence of monosaccharides or polyalcohols, it can be efficiently freeze-dried preserving the size of the liposomal vehicles and the content of a therapeutically effective amount of the photosensitizing agent. The invention also relates to the liposome composition formed upon reconstitution with an aqueous vehicle. The freeze-dried formulation upon reconstitution with a suitable aqueous vehicle forms liposomes that are also useful for intravenous administration.
