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


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


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 […]
