Biopharmaceutics – Drug Absorption – Part One – Passage of Drugs Across Cell Membranes

25-Feb-16

Key Ways For Drugs Across Cell Membranes Passive Diffusion Facilitated Diffusion Active Transport Passive Diffusion Passive diffusion is the major absorption process for most drugs. Theoretically, a lipophilic drug may pass through the cell or go around it. If the drug has a low molecular weight and is lipophilic, the lipid cell membrane is not […]

Estimate the Energy Requirements

05-Feb-16

The total amount of energy required by an individual is the sum of three basic components: basal energy expenditure (BEE) or basal metabolic rate (BMR) + energy for physical activity or exercise (PA) + thermic effect of food (TEF) 5 total energy expenditure (TEE). Basal energy expenditure is de ned as energy used for physiological functions that […]
