Malnutrition and Its Prevention: Malnutrition is not merely the absence of sufficient food—it is a silent and deeply rooted crisis that gnaws at the very foundation of human potential. It is both a cause and a consequence of disease, poverty, ignorance, and social inequality. A malnourished individual is not only physically weak, but also mentally … Read more
Nutritional and Vitamin Deficiencies: Nutrition forms the cornerstone of human development and survival, orchestrating a delicate symphony of physiological processes from cellular repair and immune defense to cognitive function and hormonal balance. When this finely tuned system is disrupted—either due to inadequate intake, poor absorption, or increased physiological demands—it results in what is commonly known … Read more
Food in Relation to Nutrition and Health Food in Relation to Nutrition and Health: Food, beyond being a source of sustenance, is an indispensable foundation for life itself—a biochemical instrument that directly governs human health, growth, development, productivity, and longevity. The quality, quantity, and diversity of food we consume are deeply interwoven with our physical, … Read more
Social Causes of Diseases: The intricate relationship between health and society is a central theme in medical sociology and public health. Disease is not merely a biological or physiological phenomenon but is deeply embedded in the social fabric of human existence. The causes of disease often extend far beyond the realm of microbes and malfunctioning … Read more
1. Concept of Disease Prevention Disease prevention refers to strategies and measures that aim to reduce the occurrence of disease, stop its progression, or minimize its consequences. These actions are taken before, during, or after the onset of disease to ensure better health outcomes. 1.1 Objectives of Disease Prevention 2. Levels of Prevention The concept … Read more
Concept of Health and Disease The concept of health and disease is fundamental to all health-related disciplines, including pharmacy, medicine, nursing, and public health. In recent decades, our understanding of these concepts has expanded dramatically—from a narrow biomedical view to a much broader, multidimensional perspective. For pharmacy students and professionals, understanding these concepts is not … Read more
Antidiuretics are pharmacological agents that reduce urine formation by increasing water reabsorption in the kidneys. These agents conserve body water and are essential in the treatment of conditions like diabetes insipidus, nocturnal enuresis, and some forms of hypotension. The primary natural antidiuretic hormone in the body is vasopressin (ADH), secreted by the posterior pituitary gland. … Read more
Diuretics are pharmacological agents that promote the excretion of water and electrolytes (primarily sodium and chloride) from the body via the kidneys, increasing urine output. They are primarily used in the management of hypertension, edematous states (such as congestive heart failure, hepatic cirrhosis, and nephrotic syndrome), and certain renal disorders. By altering renal sodium handling, … Read more
Plasma volume expanders are a diverse group of pharmacological agents and intravenous solutions used to restore and maintain the circulating blood volume, especially in cases of hypovolemia due to trauma, hemorrhage, burns, shock, or surgical procedures. They act by increasing plasma osmotic or oncotic pressure, thereby drawing fluid from the interstitial and intracellular spaces into … Read more
Definition Anti-platelet drugs, also known as platelet aggregation inhibitors, are pharmacological agents that interfere with platelet activation and aggregation—key processes in the formation of blood clots (thrombi). Unlike anticoagulants, which act on the coagulation cascade, anti-platelet agents primarily act by inhibiting platelet adhesion, activation, and aggregation, thereby reducing the risk of arterial thrombotic events such … Read more
