H1 antagonists H1 antagonists, also known as antihistamines, are a type of medication that prevents histamine from acting on H1 receptors. Histamine is a chemical that mast cells release in response to an allergic reaction, causing itching, swelling, and inflammation. H1 antagonists can alleviate or prevent these symptoms by blocking H1 receptors. Allergies such as … Read more
Histaminergic agonists Histaminergic agonists are a type of drug that stimulates the body’s histamine receptors. Histamine is a chemical that the body produces naturally and is involved in a variety of physiological processes such as immune response, inflammation, and sleep-wake cycle regulation. Histamine receptors come in a variety of forms, including H1, H2, H3, and … Read more
Glaucoma drugs Glaucoma drugs is a group of eye diseases that cause damage to the optic nerve, often as a result of high intraocular pressure. Glaucoma can be treated with a variety of medications, including: Classification TOPICAL DRUGS FOR GLAUCOMA Related Links Reference
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
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
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
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
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
Anticholinergic drugs Anticholinergic drugs are a class of medications that block the actions of acetylcholine, a neurotransmitter, in the central and peripheral nervous system. Uses They are used to treat a variety of conditions including: Classification ANTICHOLINERGIC DRUGS (Muscarinic antagonists, Atropinic drugs, Parasympatholytics) Related Links Reference
Cholinergic drugs Cholinergic drugs refer to medications that work by enhancing the effects of the neurotransmitter acetylcholine in the body. These drugs have a range of effects, including increasing muscle strength, reducing inflammation, and enhancing cognitive function. Uses Cholinergic drugs are used to treat a variety of medical conditions, including: Classification CHOLINERGIC DRUGS (Cholinomimetic, Parasympathomimetic) … Read more
