 Why This Practical Matters? After Chloride, Iron, Heavy Metals, Arsenic, Nitrate, Lead, and Boron, the Limit Test of Ammonium is an important impurity test asked in: ✔ Practical exams ✔ Viva questions ✔ Theory MCQs ✔ Competitive pharmacy exams Understanding this test also helps students link chemical reactions with visual observation, which examiners love. 🎯 Aim of the Practical To determine the amount of ammonium impurity present in a given pharmaceutical substance and ensure it is within the prescribed pharmacopoeial limit. 🧠 Principle (Easy to Remember) Ammonium salts, when treated with alkaline potassium mercuric iodide (Nessler’s reagent), produce a yellow to brown colored complex. 👉 Intensity of color ∝ amount of ammonium present The color produced by the test solution is compared with the standard solution. ⚗️ Reagents Required Nessler’s reagent Ammonium standard solution Alkaline medium (usually sodium hydroxide) Distilled water 🧪 Apparatus Nessler cylinders Measuring ...

📌 Drug Class: HMG-CoA Reductase Inhibitor (Statin) 📌 Used for: Cholesterol Control & Heart Disease Prevention 🔍 Introduction Atorvastatin is one of the most commonly prescribed drugs for lowering high cholesterol levels. It plays a vital role in preventing heart attacks, strokes, and other cardiovascular diseases, making it extremely important in both clinical practice and pharmacy education. 🧪 Chemical Information Generic Name: Atorvastatin Molecular Formula: C₃₃H₃₅FN₂O₅ Molecular Weight: 558.64 g/mol Drug Category: Statins ⚙️ Mechanism of Action (MOA) Atorvastatin works by inhibiting the enzyme HMG-CoA reductase in the liver. This enzyme is responsible for cholesterol synthesis. 🔽 Effects: Decreases LDL cholesterol Decreases triglycerides Increases HDL cholesterol 💊 Therapeutic Uses ✔ Hypercholesterolemia ✔ Mixed dyslipidemia ✔ Prevention of coronary artery disease ✔ Secondary prevention after heart attack ⚠️ Common Side Effects Muscle pain (myalgia) Headache Nausea Mild el...

📌 Introduction Limit test for sulphates ek important pharmaceutical analysis test hai jo ye ensure karta hai ki drug substance me sulphate impurities prescribed limit se zyada na ho. Ye test B.Pharm, D.Pharm aur Pharm.D exams me frequently poocha jata hai. 👉 Ye blog Limit Test Series ka next part hai, jo PharmaEasyNotes par students ke liye specially design kiya gaya hai. 🎯 Objective of Limit Test for Sulphates Drug substance me sulphate impurity detect karna Ye confirm karna ki sulphate pharmacopoeial limit ke andar hai 🧪 Principle Sulphate ions, barium chloride reagent ke sath react karke barium sulphate (BaSO₄) ka white turbidity banate hain. 📌 Reaction: SO₄²⁻ + BaCl₂ → BaSO₄ (White turbidity) 👁️ Test solution ki turbidity ko standard sulphate solution se compare kiya jata hai. 🧴 Reagents Required Barium chloride reagent Dilute hydrochloric acid Distilled water Standard sulphate solution 👉 Exam tip: Reagents ke naam short answer me bhi pooche ja sakte hain. 🔬 Procedure 🔹 T...

✨ Introduction Drug–Receptor Interaction is one of the most important and scoring topics in Medicinal Pharmaceutical Chemistry. Understanding this concept helps students easily learn advanced topics like SAR, agonists, antagonists, potency, and efficacy . 👉 If you understand this lecture well, half of medicinal chemistry becomes easy . 🔬 What is a Receptor? A receptor is a specific biological target (usually a protein) present in the body that interacts with a drug to produce a pharmacological response . 📌 In simple words: Drug = Key 🔑 Receptor = Lock 🔐 Only the correct drug can activate the correct receptor. 🧪 Types of Drug–Receptor Interactions 1️⃣ Covalent Bonding Strongest type of interaction Mostly irreversible Produces long-lasting effects 📝 Example: ✔ Aspirin binds with COX enzyme 📌 Exam Point: Covalent bonding drugs are potent but may cause toxicity. 2️⃣ Ionic (Electrostatic) Interaction Occurs between oppositely charged ions Str...
