Classification of Sulfonamide and Quinolones

classification of sulfonamides and quinolones

What Are Sulfonamides? Sulfonamides, also known as sulfa drugs, are among the oldest classes of synthetic antimicrobial agents. They work by inhibiting folic acid synthesis in bacteria, which is essential for DNA replication and cell survival. They are bacteriostatic, meaning they stop bacteria from growing rather than killing them directly. Classification of Sulfonamides Sulfonamides are … Read more

CLASSIFICATION OF BETA ADRENERGIC BLOCKERS

Beta ADRENERGIC BLOCKERS classification

Beta(β) blockers Beta(β) blockers, also known as beta-adrenergic blocking agents, are blood pressure medications. The hormone epinephrine, also known as adrenaline, is inhibited by beta blockers. Beta blockers cause the heart to beat more slowly and forcefully, lowering blood pressure. Beta blockers also aid in the widening of veins and arteries, which improves blood flow. … Read more

CLASSIFICATION OF ALPHA ADRENERGIC BLOCKERS

classification of Alpha ADRENERGIC BLOCKERS

Alpha (α)-adrenergic blockers Alpha (α)-adrenergic blockers, also known as alpha-blockers, are a class of drugs that block the action of the alpha-adrenergic receptors in the body. These receptors are found in various tissues, including blood vessels, the bladder, and the prostate gland. Alpha (α)-blockers are commonly used to treat conditions such as high blood pressure, … Read more

CLASSIFICATION OF ADRENERGIC DRUGS

adrenergic drug classification

Adrenergic drugs Adrenergic drugs, also known as sympathomimetic drugs. These are a class of medications that activate the sympathetic nervous system. These drugs mimic the effects of the neurotransmitters norepinephrine and epinephrine, which are released by the adrenal glands in response to stress or danger. Adrenergic drugs are used to treat a variety of medical … Read more

CLASSIFICATION OF GANGLIONIC BLOCKING AGENTS

Ganglionic blocking agents A family of medications known as ganglionic blocking agents, also referred to as ganglionic blockers, affects the autonomic nervous system by preventing the transmission of nerve impulses at ganglia, which are collections of nerve cell bodies outside the central nervous system. Ganglionic blockers were once used to address conditions like hypertension, angina, … Read more

Classification of Ganglionic Stimulants

classification of ganglionic stimulants

Ganglionic stimulants Ganglionic stimulants are drugs that activate the autonomic ganglia. These are nerve cell clusters that regulate involuntary functions such as heart rate, blood pressure, and digestion. They were historically used to treat conditions such as hypotension and urinary retention, but are now rarely used due to their high potential for adverse effects, such … Read more
