問題陳述：

無定形固體分散體（ASD）是一種透過擴大溶解力、潤濕性和崩解率來提高水溶性不足的動態藥物固定物（API）的生物利用度的既定計劃策略。透過熱軟化排出 (HME) 有效地組裝 ASD 計劃需要選擇正確的 API 負載、賦形劑和處理溫度等。編程介面負載對於決定藥物產品的重要品質特徵同樣至關重要，例如確保產品在其使用壽命期間穩定運行的長期物理可靠性。區分 HME 可實現性和風險評估的可能的最極端藥物負載限制和輔料，以及製成的 ASD 的長期物理強度可能非常具有挑戰性，因此儘管延遲了可靠性檢查，仍需要進行一些排除準備工作。無定形強散射（ASD）正在被用於開發溶解不足的藥物混合物，其復發率不斷增加。這些框架由聚合物平衡的未定義的動態藥物固定組成，以創建具有改善的物理和結構穩定性的框架。 ASD 通常被認為是提高功能性藥物固定物的明確償付能力的一種方法。

這項調查將研究自閉症譜系障礙的排列和描述技術，重點是理解和預期安全。將重點放在對超級沉浸感的假設理解和預見體內執行。此外，還將介紹臨床前和臨床進展工作的概要，以使讀者了解建構 ASD 時的危險和關鍵問題。雲狀強散射（ASD）是一種很有前景的方法，可以提高無效水溶性藥物的溶解能力、崩解率和生物利用度。由於用於交付 ASD 的計劃和程序不同，ASD 的物理化學性質很混亂。這些特性會影響他們的身體穩定性，因此為自閉症譜系障礙制定影響深遠且成功的描繪策略至關重要。結合使用這些方法可以提高我們對 ASD 特性的理解。影響 ASD 性能的關鍵因素包括玻璃化溫度 (Tg)、原子可移植性、混溶性和結晶度。模糊的強烈狀態提供了改進的透明溶解性和崩解率。無論如何，由於在製備、儲存和分解過程中熱力學脆弱和重結晶傾向，它們的潛在應用受到限制。因此，創建具有令人滿意的可靠性的未定義藥物仍然是一項重要的測試，並且依賴強原子散射的詳細方法學正在被濫用。共同不明確的框架是另一種計劃方法，其中無形的藥物透過低亞原子共同前體的可靠分子間通訊來平衡。

這項調查涵蓋了與共雲藥物運輸框架相關的一些主題。具體來說，它描繪了聯合星雲結構、規劃和強大的國家形象方面的最新進展，就像瓦解執行和保留的升級是實質內容一樣。給出了藥物鎮靜劑、鎮靜羧基腐蝕劑和藥物氨基腐蝕劑共雲散射通過氫保持、π-π合作和離子功率合作的實例，並比較了最後的劑量結構。

Fruitful improvement of shapeless strong scattering definitions relies upon three essential elements: dynamic pharmaceutical fixing properties, settling polymer, and the preparing innovation. Polymer gives the central structure to settling the nebulous structure and the procedure supplies the vitality required to change the framework into a shapeless structure. This is apparent from plentiful models where just physical blending of the shapeless medication and polymer didn't give agreeable result as far as either improving the solvency or upgrading the bioavailability. Viability of the procedure is basic to produce, catch, and protect the nebulous structure. The accomplishment of these procedures is reliant on the procedure time and the super immersion conditions that are being produced during the arrangement of the strong scattering. From the disclosure of strong scatterings in the mid 1960s, the utilization of strong scattering idea to fathom solvency challenges in certifiable was restricted and this was somewhat because of the absence of industrially suitable preparing innovations.

Be that as it may, in the previous two decades this territory has seen astounding improvement as the science and comprehension of the assembling advances, explicitly splash drying and dissolve expulsion, have advanced significantly prompting a few monetarily fruitful formless items notwithstanding various being developed. Other than propelling the field and logical understanding, numerous innovation driven organizations have flourished in this condition by empowering the improvement of inadequately water-dissolvable medications that would have in any case been dropped from thought. Shower drying and hot-dissolve expulsion have become the foundation of undefined plans in the pharmaceutical business while more current advances are continually being added to the tool compartment that guarantee to improve quality, profitability, as well as better execution of the items. Approaching numerous advancements immensely builds the likelihood of accomplishment for a huge assortment of mixes. The decision of innovation is essentially administered by the physicochemical properties of the medication substance, accessibility of innovation from lab scale to business scale, vigor of the procedure, item execution, and in conclusion the effect of the chose innovation on the expense of products. Investigating the ideal structure space during early period of plan improvement by this methodology requires noteworthy measure of assets including API which might be limitedly accessible during this stage.

Methodology & Theoretical Orientation:

PC-SAFT 是依賴可測量夥伴液體假設 (SAFT) 的表達條件。與其他 SAFT 狀態條件一樣，它使用實際的力學策略（特別是乾擾假設）。一種節省API 的方法，應用新穎的實驗模型和徹底的熱力學擾動鏈統計關聯流體理論(PC-SAFT) 來演示幾個計劃的ASD 階段圖，成功快速地研究了結構。進行了HME 製造和長期安全檢查（長達一年半），以檢查模型的預期結果，包括Soluplus、檢查中使用了共聚維酮、PVP 和 HPMCAS。

發現：

這些演示儀器被認為完全適合評估生產無寶石 ASD 計劃所需的排出溫度，以及預測其在各種儲存條件（即溫度和相對悶熱度）下的物理可靠性。

結論及意義：

有先見之明的 ASD 階段圖不斷取得進展，最終成為用於輔料選擇、HME 溫度預測以及針對最極端藥物負荷和人身安全規劃 ASD 詳細資訊的可靠工具。應用這些工具可以利用更少的資產和材料來實現有效的 ASD 定義簡化。
