Factors Affecting Dissolution Rate
Solubility of drug plays a prime role in controlling its dissolution from dosage form. Aqueous solubility of drug is a major factor that determines its dissolution rate. Minimum aqueous solubility of 1% is required to avoid potential solubility limited absorption problems. Studies of 45 compound of different chemical classes and a wide range of solubilities revealed that initial dissolution rat...
متن کاملFactors Affecting Conception Rate
An analysis of dairy herd records to determine the cause of low reproductive efficiency usually leads to the conclusion that problems are centered in one of the following areas: breeding policy (intentionally waiting too long after calving for first service), estrous detection efficiency (missed heats), or conception rate. The challenge is to identify the factors responsible for the problem. On...
متن کاملFactors Affecting Penetration of Ciprofloxacin in Lower Extremity Ischemic Tissues.
The aims of this study were to evaluate factors influencing the distribution of ciprofloxacin in tissue of patients suffering from varying degrees of peripheral arterial disease (PAD). Blood and tissue samples were collected from patients undergoing debridement or amputation procedures and the amount of ciprofloxacin in them was determined using high-performance liquid chromatography. All patie...
متن کاملFactors Affecting Filter Penetration and Quality Factor of Particulate Respirators
In the present study, a theoretical model was used to examine factors affecting the filtration characteristics of filters used for respiratory protection. This work was designed to support the particulate filter test requirements established in 1996. The major operating parameters examined in this work include face velocity, fiber diameter, packing density, filter thickness, and fiber charge de...
متن کاملFactors affecting revision rate of chronic rhinosinusitis
OBJECTIVE Chronic rhinosinusitis (CRS) is a variable multifactorial disease. It can be divided into forms with nasal polyps (CRSwNP) and without (CRSsNP). Sinus and/or nasal polypectomy surgery are considered if maximal conservative treatment is insufficient. The predictive factors of the need of revision surgery comprise mostly the CRSwNP phenotype and are not fully understood. STUDY DESIGN ...
