🧪 Limit Test of Calcium(Inorganic Pharmaceutical Chemistry – Practical Guide)

Calcium is an essential element, but excess calcium as an impurity in pharmaceutical substances can affect drug stability, solubility, and quality. That’s why the Limit Test of Calcium is performed to ensure that calcium content remains within pharmacopoeial limits. 📌 Objective of Limit Test of Calcium To detect and control the amount of calcium impurity present in pharmaceutical substances by comparing the test solution with a standard solution. 🧠 Principle Calcium reacts with ammonium oxalate in an alkaline medium to form a white precipitate of calcium oxalate. 👉 The turbidity produced in the test solution should not be more intense than that of the standard solution. 🧫 Chemical Reaction White precipitate of Calcium Oxalate is formed. ⚗️ Apparatus Required Nessler cylinders Measuring cylinder Beakers Glass rod 🧪 Reagents Required Ammonium oxalate solution Dilute ammonia solution Calcium standard solution Distilled water 🧪 Procedure 🔹 Preparation of Test Solution Take the given...

Prodrugs: Smart Drug Design for Better Therapy(Medicinal Pharmaceutical Chemistry | B.Pharm Semester 4)

🌟 Introduction  Have you ever wondered 🤔 👉 Why some drugs are modified before being given to patients? 👉 Why a drug is inactive at first but becomes active inside the body? The answer is PRODRUGS — one of the most interesting and scoring topics in Medicinal Chemistry. 🧠 What is a Prodrug? (Easy Definition) A prodrug is a pharmacologically inactive or less active compound that is converted into an active drug inside the body through metabolic processes. 📌 Exam-friendly line: Prodrugs are inactive derivatives designed to improve the pharmacokinetic properties of active drugs. 🎯 Why Are Prodrugs Used? Prodrugs are designed to overcome problems like: ✔ Poor absorption ✔ Low bioavailability ✔ High toxicity ✔ Bad taste or irritation ✔ Short duration of action 👉 Simply put: Better drug delivery + better patient compliance 🔬 Types of Prodrugs (Very Important for Exams) 1️⃣ Carrier-linked Prodrugs Drug + carrier molecule Cleaved by enzymes Example: 👉 Aspirin → Salicylic acid 2️⃣ B...
