Systems of solids in liquids include the most frequently encountered and probably the most important type of pharmaceutical solutions. Many important drugs belong to the class of weak acids and bases. They react with strong acids and bases and, within […]
Effect of Ionic Dissociation and Molecular Association on Partition: The solute can exist partly or wholly as associated molecules in one of the phases or it may dissociate into ions in either of the liquid phases. The distribution law applies […]
PEPTIC ULER: Peptic ulcer are open sores that develop on the inner lining of the stomach and the upper portion of small intestine. It occurs in that part of the g.i.t which is exposed to gastric acid secretions. Types of […]
Bronchial Asthma: It is chronic condition in which a person’s airways become inflamed swell, narrow and produce extra mucus which make difficulty in breathing. Sign and symptoms: Coughing, shortness of breath, chest tightness and wheezing sound (whistling sound in airways). […]
Combined Effect of pH and Solvents: Stockton and Johnson and Higuchi studied the effect of an increase of alcohol concentration on the dissociation constant of sulfathiazole, and Edmonson and Goyan investigated the effect of alcohol on the solubility of phenobarbital. […]
COUGH: It is physiologically useful protective reflex that clears the respiratory tract of the accumulated mucus and foreign substances. It occurs due to stimulation of mechano/chemo receptors in throat, respiratory, passage or stretch receptors in the lung Types of cough: […]
COPD: Chronic obstructive pulmonary disease, a group of lung disease that blocks airflow and make it difficult to breathe. Types of COPD: There are two main types of COPD. Chronic bronchitis: Which involves a long term cough with mucus. Emphysema: […]
ELECTRICAL PROPERTIES OF INTERFACES: The existence of difference in electrical potential across a solid–liquid interface is demonstrated by the following phenomena: Electrophoresis: Movement of dispersed particles through a liquid medium under the influence of an electric field. Electro-osmosis: Movement of […]
