Penicillin, the most important antibiotic, was first extracted from the mould Penicillium notatum. Subsequently, a mutant of a related mould, P. chrysogenum, was found to give the highest yield of penicillin and is employed for the commercial production of this antibiotic. Penicillin belongs to a group of antibiotics called β-lactam antibiotics. The basic structure of … Read more
Beta-lactam antibiotics are a class of antibiotics characterized by the presence of a beta-lactam ring in their molecular structure. This ring is crucial for its antibacterial activity as it interferes with the synthesis of bacterial cell walls, ultimately leading to bacterial cell death. Beta-lactam antibiotics are generally well-tolerated but can cause allergic reactions in some … Read more
Dry powder for reconstitution is a pharmaceutical dosage form where a dry, powdery mixture of active ingredients and excipients is packaged for reconstitution into a liquid preparation by adding a specified amount of solvent, typically water, immediately before use. This form is particularly suitable for drugs that are unstable in liquid form over extended periods. … Read more
Pharmacological classification of drugs in relation to pharmacognosy categorizes drugs based on their pharmacological effects and mechanisms of action, particularly focusing on bioactive compounds derived from natural sources such as plants, animals, and minerals. This classification system provides insights into the therapeutic uses, pharmacological properties, and biological targets of medicinal substances. Introduction to Pharmacological Classification: … Read more
Microbiology is the scientific discipline that focuses on the study of microorganisms, which are microscopic organisms that are too small to be seen with the naked eye. This field encompasses many organisms, including bacteria, viruses, fungi, protozoa, and algae. Microorganisms play crucial roles in various ecological, industrial, and medical processes, and microbiologists investigate their structure, … Read more
Antimicrobials refer to substances or agents that can inhibit the growth or destroy microorganisms, including bacteria, viruses, fungi, and parasites. These agents are crucial in preventing, controlling, and treating infectious diseases in humans, animals, and plants. Different classes of antimicrobial agents are designed to target specific types of microorganisms or interfere with their growth and … Read more
