Factors Influencing Drug Absorption: Physicochemical Parameters

274
The physicochemical characteristics of drugs play a crucial role in formulating stable and bioavailable drug products. The solubility of a drug, governed by the varying pH along the GI tract and its dissociation constant (pKa), is pivotal in determining its ionization state and absorption rate. Notably, weak acids and bases remain unionized and are absorbed more rapidly.
Enhanced drug absorption can be achieved by reducing particle sizes and increasing surface areas, thereby facilitating...

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Factors Influencing Drug Absorption: Pharmaceutical Parameters

Solid dosage forms such as tablets and capsules undergo rigorous manufacturing processes to ensure stability and effectiveness. Their dissolution and absorption properties are influenced significantly by the choice of excipients (inactive ingredients that serve various roles in the formulation), and the methodology applied during production. The manufacturing parameters, such as compression force and granulation techniques, significantly affect dissolution rates. Elevated compression forces...

Factors Influencing Bioavailability: First-Pass Elimination

6.3K
When a drug is taken orally, it undergoes a journey starting from the gastrointestinal (GI) tract, passing through the portal vein, reaching the liver, and finally entering the systemic circulation. This process involves the absorption of the drug across the GI tract. The liver is the primary site for metabolizing the drug, with some metabolism also occurring in the gut wall. This journey significantly reduces the quantity of the drug that reaches the systemic circulation, a phenomenon known as...

Factors Influencing Drug Absorption: Anatomical Parameters

204
Drug absorption involves the movement of drugs from the point of administration into the systemic circulation. Initially, Gastrointestinal (GI) motility propels the drug through the digestive tract and into the stomach. However, the stomach's high acidity and limited surface area restrict its role in drug absorption for most drugs. The drug then moves from the stomach to the small intestine via gastric emptying, which can be slowed by various factors, including interactions with other...

Factors Influencing Drug Absorption: Presystemic Elimination

217
The pharmacokinetic journey of oral drugs begins with a crucial first pass through the hepatic portal system, called the first-pass effect. This first pass significantly impacts bioavailability — the proportion of a drug that enters systemic circulation and is available for therapeutic action. The primary route sees the drug absorbed by intestinal membranes and then shunted to the liver via the hepatic portal vein. Here, pre-systemic elimination occurs as drugs face metabolism or biliary...

Area of Science:

  • Animal Science
  • Dairy Science
  • Nutritional Science

Background:

  • Algerian Saharan populations rely on bovine milk, facing sustainability challenges.
  • Camel milk (Camelus dromedarius) demand is rising due to market needs in livestock and dairy.
  • Understanding nutritional impacts on camel milk quality is crucial for sustainable production.

Purpose of the Study:

  • To analyze the effect of different nutritional regimes on the quality of camel milk.
  • To identify key dietary components influencing milk's major constituents and nutritional value.

Main Methods:

  • Analysis of milk parameters including pH, acidity, ash, and fat content.
  • Correlation studies between milk constituents and various feed components (barley, wheat bran, concentrates, etc.).
  • Evaluation of energy-protein balance (g PDI/UFL) and its effect on milk protein.
  • Assessment of vitamin C content in relation to dietary factors.

Main Results:

  • Significant differences observed in pH, acidity, ash, and fat content based on diet.
  • Intensified feeding (higher concentrates) negatively affected pH.
  • Milk constituents positively correlated with barley, wheat bran, Total Nitrogen/Kg. Dry Matter (TN/Kg.DM), Dry Matter intake (Kg.DM), concentrates, and watering.
  • Optimal energy-protein balance (around 73 g PDI/UFL) improved milk protein ratio.
  • Corn, soybeans, palm dates, and Vitamin Mineral (VM-premix) supplementation favored fat synthesis.
  • Crude fiber and cell walls were better utilized for fat synthesis with concentrate availability and increased TN/Kg.DM and VM-premix.
  • Vitamin C content increased with higher UFL/Kg.DM and PDI/UFL ratios.

Conclusions:

  • Nutritional status significantly influences camel milk quality, affecting key parameters like protein and fat.
  • Strategic dietary management, including specific feed components and energy-protein balance, can optimize milk production and quality.
  • Further detailed studies are needed to fully understand and leverage nutritional impacts for enhanced camel dairy farming.
