Drug Solubility: Importance and Enhancement Techniques

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3399483/
    Jul 05, 2012 · The partition coefficient (Log P) is a measure of differential solubility of a compound in a hydrophobic solvent (octanol) and a hydrophilic solvent (water). The logarithm of these two values enables compounds to be ranked in terms of hydrophilicity (or hydrophobicity).Author: Ketan T. Savjani, Anuradha K. Gajjar, Jignasa K. Savjani

Importance of Partition Coefficient in Formulation Development

    http://www.authorstream.com/Presentation/sagarpharmavision-1202382-importance-of-partition-coefficient-in-formulation-development/
    Sep 25, 2011 · Generally, compounds with log P values between 3 and 6 show good absorption, whereas those with log P greater than 6 or less than 3 often have poor transport characteristics.

Formulation of Poloxamers for Drug Delivery

    https://www.mdpi.com/2079-4983/9/1/11/pdf
    formulations are emphasized due to their important contribution to drug delivery mechanisms. Insights into the underlying mechanisms described may be useful to formulators. Important parameters such as drug release rate and formulation stability are directly linked to poloxamer associative and adsorption properties.Author: Andrew M. Bodratti, Paschalis Alexandridis

How important is LogP in drug design? - Quora

    https://www.quora.com/How-important-is-LogP-in-drug-design
    Mar 13, 2014 · Quite important, log P can affect bioavailability, where the drug ends up in the body in the highest concentration, and it's ability to cross the blood-brain barrier. As I'm sure you're aware, log P is a measure of how hydrophobic or hydrophilic a molecule/drug is.

Self-Emulsifying Drug Delivery Systems (SEDDS) in ...

    Lipid-based formulations, such as Self-Emulsifying Drug Delivery Systems (SEDDS), are an important tool for lipophilic drugs and offer the potential for enhancing drug absorption and oral bioavailability. SEDDS are a promising approach for the formulation of drug compounds with poor aqueous solubility. These systems are easilyAuthor: Beatriz Zanchetta, Marco Vinícius Chaud, Maria Helena Andrade Santana

LogP—Making Sense of the Value

    https://www.acdlabs.com/download/app/physchem/making_sense.pdf
    LogP = 1 means there is a 10:1 partitioning in Organic : Aqueous phases. Although log P is a constant, its value is dependent on the choice of the organic partitioning solvent and, to a lesser degree, on the conditions of measurement.

A REVIEW ON PHARMACEUTICAL PREFORMULATION STUDIES IN ...

    http://ijpsr.com/bft-article/a-review-on-pharmaceutical-preformulation-studies-in-formulation-and-development-of-new-drug-molecules/?view=fulltext
    It focuses on drug‐solvent interactions that could occur during the delivery of a drug candidate. For example, orally administered drug should be examined for solubility in simulated gastric media. We need to perform solubility analysis of a new drug to provide a basis for later formulation work and can affect drug performance.

Pharmaceutical Formulation - an overview ScienceDirect ...

    https://www.sciencedirect.com/topics/medicine-and-dentistry/pharmaceutical-formulation
    Various vehicles may be used for drug formulation but, also for this route of drug administration, the possible modulation of drug pharmacokinetics and pharmacodynamics must always be taken into account. For oral dosage forms in aqueous solution, osmolarity and viscosity are of importance.

What are the Different Forms of Drug Formulation?

    https://www.cognibrain.com/pharmaceutical-formulations/
    Pharmaceutical formulation is the process of combining various chemical substances with the active drug to form a final medicinal product, which is called a drug mixture or drug formulation. A drug formulation can be given to the patient in various forms like solid, semisolid or liquid.

Partition coefficient - Wikipedia

    https://en.wikipedia.org/wiki/Partition_coefficient
    The partition coefficient, abbreviated P, is defined as a particular ratio of the concentrations of a solute between the two solvents (a biphase of liquid phases), specifically for un-ionized solutes, and the logarithm of the ratio is thus log P.
