Significance of Dissolution rate
Dissolution rate is the speed at which a substance, often a drug, dissolves in a solvent. It's crucial for bioavailability and therapeutic effectiveness. Factors like surface area, concentration gradients, particle size, and the presence of wetting agents can influence it. Techniques like cyclodextrin complexation, milling, and solid dispersion can improve dissolution. The USP basket method is a common analysis technique, with studies often conducted at specific temperatures and pH levels to evaluate formulations.
Synonyms: Dissolution velocity, Disintegration rate, Release rate, Dissolution speed, Decomposition rate, Breakdown rate

Hindu concept of 'Dissolution rate'
In Hinduism, dissolution rate mirrors the speed a substance dissolves, influenced by surface area and concentration gradients. This concept parallels the cyclical nature of creation and destruction.
From: Journal of Ayurveda and Integrated Medical Sciences
(1) The speed at which a solid substance dissolves in a solvent, represented by dm/dt, is directly influenced by factors like the surface area and concentration gradients.[1]
The concept of Dissolution rate in scientific sources
Dissolution rate is the speed a drug dissolves in a solvent, impacting absorption, bioavailability, and effectiveness. Enhancing dissolution is key, especially for poorly soluble drugs, using techniques like complexation or particle size reduction.
From: International Journal of Pharmacology
(1) The effect of rotation speed on the rate of heterogeneous reactions led to an empirical relationship between this rate and the intensity of agitation.[2] (2) This is the speed at which a solid substance dissolves, which is crucial for drug absorption.[3]
From: Asian Journal of Pharmaceutics
(1) This is the speed at which a drug dissolves in a medium, and it can be improved by formulating the drug as nanoparticles.[4] (2) Nagarsenker MS, Meshram RN, Ramprakash G. Solid dispersion of hydroxypropyl beta-cyclodextrin and ketorolac: Enhancement of in-vitro these, improvement in anti-inflammatory activity and reduction in ulcerogenicity in rats.[5] (3) The most important parameter which may greatly affect the performance of drug is solubility. Aqueous solubility is an important physicochemical property of drug in therapeutic activity.[6]
From: International Journal of Environmental Research and Public Health (MDPI)
(1) This refers to how quickly a substance breaks down into its constituent ions or molecules, and for silver nanoparticles in soil, it plays a significant role in determining the availability of silver ions and subsequent toxicity.[7] (2) Dissolution rate is a characteristic describing how quickly a material breaks down in a solution, which was measured for AH Plus and MTA Fillapex over the long term alongside their cytotoxicity and pH levels.[8] (3) Tristearin based SLMs were able to increase the dissolution rate of Fer-Me in water, also inducing a control of the release of both Fer and Fer-Me.[9]
From: Sustainability Journal (MDPI)
(1) Dissolution rates refer to how quickly the solid source materials break down in the alkaline solution, a process that is enhanced by using a sodium hydroxide solution because of its inherent exothermic characteristics.[10] (2) It is a factor that needs to be considered during the toxicity of nanoparticulate systems and bioaccumulation tests while interpreting the results or designing experiments.[11] (3) The dissolution rate of contaminant mass from fingers was suspected to occur faster than for pools, due to which aqueous phase concentrations were governed predominantly by the dissolution of DNAPL from pools.[12]
From: International Journal of Pharmacology
(1) In preparing pharmaceutical solid dosage form, milling process is generally used for reducing the particle size of a solid drug to increase its dissolution rate.[13] (2) Dissolution rate is the speed at which a solid substance dissolves into a liquid, a property improved by cyclodextrin complexation.[14]
