development of metabolic syndrome, increasing the risk for cardiovascular disease and diabetes.
How do beta-blockers work in managing heart conditions?
✔✔Beta-blockers work by blocking the effects of adrenaline on beta-adrenergic receptors,
reducing heart rate and contractility, which lowers blood pressure and helps manage conditions
like hypertension and heart failure.
What is the role of histamine in allergic reactions?
✔✔Histamine is released by mast cells during an allergic reaction, causing symptoms like
itching, swelling, and mucus production as part of the immune response to perceived threats.

diabetes, hypertension, and increased risk of infections due to immune suppression.
Explain the mechanism of action for angiotensin-converting enzyme (ACE) inhibitors.
✔✔ACE inhibitors prevent the conversion of angiotensin I to angiotensin II, leading to
vasodilation, decreased blood volume, and reduced blood pressure, making them effective in
treating hypertension and heart failure.
What is the relationship between inflammation and chronic diseases?
✔✔Chronic inflammation is a contributing factor to many diseases, including heart disease,
diabetes, and cancer, as it can lead to tissue damage and dysfunction over time.
Describe the process of ischemia and its effects on tissues.
✔✔Ischemia is a reduction in blood flow to tissues, leading to a lack of oxygen and nutrients,
which can result in tissue damage, pain, and potential necrosis if prolonged.
What is the significance of therapeutic drug monitoring?
2
, ✔✔Therapeutic drug monitoring is important for optimizing medication dosages, ensuring
efficacy while minimizing toxicity, particularly for drugs with narrow therapeutic indices.
How do antipsychotic medications help manage schizophrenia?
✔✔Antipsychotic medications work by altering the effects of neurotransmitters in the brain,
particularly dopamine, which helps reduce symptoms like hallucinations and delusions in
patients with schizophrenia.
What are common signs of heart failure?
✔✔Common signs of heart failure include shortness of breath, fatigue, swelling in the legs and
ankles, and persistent coughing or wheezing due to fluid accumulation.
How do lifestyle changes impact hypertension management?
✔✔Lifestyle changes, such as adopting a low-sodium diet, regular exercise, weight loss, and
stress management, can significantly lower blood pressure and reduce reliance on
antihypertensive medications.
