Drug Classifications and Uses

Beta Blocker: A class of medications used primarily to manage cardiovascular conditions. Examples include propranolol and atenolol.
Digoxin: Primarily used to treat heart failure and certain arrhythmias by increasing cardiac contractility.
H2 Receptor Antagonist: Used to reduce stomach acid production. Example includes ranitidine, which blocks histamine H2 receptors.
Local Anesthetics: Drugs that cause temporary loss of sensation in a specific area. Examples include lidocaine and bupivacaine.

Physiological Effects

Nitric Oxide: A potent vasodilator that relaxes vascular smooth muscle, leading to decreased blood pressure and increased blood flow.

Enzymatic Actions

NSAIDs Action: Nonsteroidal anti-inflammatory drugs work primarily by inhibiting the cyclooxygenase (COX) enzymes, which play a key role in inflammation and pain.

Treatment Modalities

Chronic Heart Failure: Managed with a combination of medications, including ACE inhibitors, beta blockers, and diuretics. Digoxin may also be included in treatment.
Hypercholesterolemia Treatment: Statins are commonly prescribed to lower cholesterol levels in the blood.

Drug Safety and Side Effects

Pulmonary Fibrosis Risk: Certain medications, such as amiodarone, have been associated with the development of pulmonary fibrosis.
Aspirin: Known for its antiplatelet effects, effective for prevention of thrombotic events. Aspirin also has anti-inflammatory properties.

Gastric Functions

Gastric Acid Secretion Stimulus: Acetylcholine is the neurotransmitter that stimulates gastric acid secretion in the stomach.
