牛皮癣、皮炎和湿疹是炎症性皮肤病,可以用二丙酸贝托米松(一种极强的皮质类固醇)治疗。这是肾上腺皮质类固醇的人工对应物。
脂溢性皮炎疗效:外用Betamethasone Dipropionate(二丙酸倍他米松)治疗脂溢性皮炎的临床症状(包括红斑、鳞屑、瘙痒及炎症)较安慰剂显著改善。治疗2-4周后,达到“痊愈”或“显著改善”的患者比例为65%-82%[1] - 优于弱效糖皮质激素:在缓解重度鳞屑和瘙痒方面,Betamethasone Dipropionate(二丙酸倍他米松)疗效优于弱效外用糖皮质激素(如氢化可的松),症状评分平均降低40%-55%,而弱效激素组为20%-30%[1] - 预防复发:每周2-3次的低剂量维持治疗可使脂溢性皮炎复发率在12周随访期内降低38%,显著优于无维持治疗组[1] |

Local skin adverse effects: The most common adverse events associated with topical Betamethasone Dipropionate were mild to moderate local irritation (12-18% of patients), including burning, stinging, and dryness. These effects were usually transient and resolved after treatment discontinuation [1]
- Long-term use risks: Prolonged (≥8 weeks) continuous use of Betamethasone Dipropionate was associated with an increased risk of skin atrophy (4-6% of patients), telangiectasia (2-3%), and hypopigmentation (1-2%) [1] - Systemic absorption risk: Minimal systemic absorption was observed with topical application; no significant changes in serum cortisol levels or systemic corticosteroid-related adverse effects (e.g., hypertension, hyperglycemia) were reported in clinical trials [1] |

Betamethasone dipropionate is a steroid ester that is betamethasone in which the hydroxy hydrogens at positions 17 and 21 are replaced by propanoyl groups. It is used in combination with calcipotriene hydrate, a synthetic vitamin D analogue, for the topical treatment of plaque psoriasis in adult patients. It has a role as an antipsoriatic. It is a steroid ester, an 11beta-hydroxy steroid, a 20-oxo steroid, a fluorinated steroid, a propanoate ester and a 3-oxo-Delta(1),Delta(4)-steroid. It is functionally related to a betamethasone.
Betamethasone dipropionate has been reported in Dodonaea polyandra with data available. Betamethasone Dipropionate is the 17,21-dipropionate ester of betamethasone, a synthetic glucocorticoid with metabolic, immunosuppressive and anti-inflammatory actions. Betamethasone dipropionate binds to specific intracellular glucocorticoid receptors and subsequently binds to DNA to modify gene expression. The synthesis of certain anti-inflammatory proteins is induced while the synthesis of certain inflammatory mediators is inhibited. As a result, there is an overall reduction in chronic inflammation and autoimmune reactions.

Betamethasone Dipropionate is a medium-to-high potency topical corticosteroid used for the treatment of inflammatory dermatoses, including seborrhoeic dermatitis [1] - Its therapeutic effect in seborrhoeic dermatitis is mediated by anti-inflammatory, antipruritic, and antikeratinizing properties [1] - The Cochrane review concluded that topical Betamethasone Dipropionate is effective for short-term (2-4 weeks) treatment of moderate-to-severe seborrhoeic dermatitis, but long-term continuous use should be avoided to minimize local skin adverse effects [1] |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
