Determines onset, intensity, and duration of drug action. Important for pharmacokinetics and therapeutic effect. ⏱️ 2:06 – SITE OF DRUG ABSORPTION 🌐 Oral: Stomach, Small intestine (mainly duodenum & jejunum) Sublingual/Buccal: Mouth (fast absorption) Rectal: Rectum Parenteral (IV, IM, SC): IV = direct → no absorption Topical/Transdermal: Skin (slow, steady) Inhalation: Lungs (rapid, large surface area) ⏱️ 4:47 – MECHANISM OF DRUG ABSORPTION ⚡ Passive diffusion: High → low concentration, most common Facilitated diffusion: Carrier proteins, no energy required Active transport: Carrier + energy (ATP), against gradient Endocytosis / Pinocytosis: Rare, for large molecules ⏱️ 5:44 – FACTORS AFFECTING DRUG ABSORPTION ⚖️ 5:56 Physicochemical factors: Solubility, pH, ionization, molecular size 9:57 Biological factors: Blood flow, surface area, GI motility, presence of food 12:26 Pharmaceutical factors: Tablets, suspensions, solutions 15:30 Pharmacokinetic factors #DrugAbsorption #Pharmacokinetics #OralAbsorption #SublingualAbsorption #RectalAbsorption #IVDrugs #IMDrugs #TransdermalDrugs #InhalationDrugs #PassiveDiffusion #ActiveTransport #FacilitatedDiffusion #Endocytosis #DrugMechanism #DrugFormulation #Bioavailability #FactorsAffectingAbsorption #BloodFlow #GIMotility #DrugInteractions #Solubility #Ionization #MolecularSize #MedicalStudents #PharmacyStudents #NursingStudents #MBBS #BPharm #GPAT #NCLEX #USMLE #Pharmacology #StudyNotes #ClinicalPharmacology #HealthcareEducation #BrainHealth #Medicine
