  PHARMA BY AQSA MURTAZA (PharmD) Aim to help Pharmacy Students. We cover a wide range of topics, from Medicinal Chemistry, Pharmacology, and Drug Inte ractions to Medication Management and Disease State Management. Medicinal Chemistry DIURETICS Site of action of each Diuretic It acts on the nephron. There are four sites in the nephron where it can act: 1. Site I - Proximal Convoluted Tubule (PCT) 2. Site II - Ascending Loop Of Henle 3. Site III - Distal Convoluted Tubule (DCT) 4. Site IV - Collecting Duct Drugs acting on PCT inhibit carbonic anhydrase 1. Acetazolamide 2. Methazolamide Drugs acting on ascending loop of henle inhibit the co-transport system 1. Furosemide 2. Ethacrynic Acid Drugs acting on DCT inhibit Na+/Cl- cotransporter 1. Chlorothiazide 2. Hydrochlorothiazide Drugs acting on the collecting duct inhibit Na+ reabsorption and K+ excretion 1. Spironolactone 2. Triamterene Acetazolamide • Acetazolamide act on site I - PCT. • Drugs acting on site I are 5-...

We cover a wide range of topics, from Medicinal Chemistry, Pharmacology, and Drug Inte ractions to Medication Management and Disease State Management. CORTISOL PROPERTIES Antiinflammatory hormone White crystalline powder Water insoluble and soluble in organic solvents Rapidly absorbed from GIT Can cross the placenta barrier Synthesized in Zona fasciculate and Zona reticularis cells INDICATION Allergy Immunosuppressants ADR Osteoporosis SAR Flouride ion in place of the hydroxyl group with methyl increases its activity. Activity decreases if the hydroxyl group is replaced with chlorine or bromine group. Unsaturation in ring A lead to an increase in the activity of the drug. Substitution of the hydroxy group in ring B leads to a decrease in the activity of the drug. Structure of Cortisol GLUCAGON Contain 29 amino acids Synthesized in Pancrease A large dose of it leads to the intestine relaxation Have ionotropic effects o...
