Study Notes

Laxatives

Dehydrocholic acid is used to treat chronic cholecystitis, pyelitis, chronic pyelonephritis, cystitis, and acute pancreatitis.
Laxatives containing anthraglycosides (buckthorn bark, rhubarb root, senna leaves) increase peristalsis of the large intestine, have an effect within 3-4 hours, and are prescribed for acute constipation.
Saline laxatives (magnesium sulfate) act only on the large intestine, suppress intestinal motility, and inhibit intestinal mechanoreceptors.

Diuretics

Diuretics with a direct effect on the function of the renal tubular epithelium (dichlorothiazide, spironolactone) reduce the filtration of proteins.
Potassium-sparing diuretics (triamterene) block aldosterone receptors and reduce the filtration of proteins.
Spironolactone blocks aldosterone receptors and reduces the filtration of proteins.

Antibiotics

Biosynthetic penicillins (benzylpenicillin sodium salt) have a broad spectrum of antimicrobial action and are resistant to penicillinase.
Long-acting biosynthetic penicillins (benzylpenicillin novocaine salt) are highly toxic, disrupt the permeability of the cytoplasmic membrane, and are prescribed only parenterally.
Ampicillin has a broad spectrum of antimicrobial action, is resistant to penicillinase, and is administered orally.
Tetracycline group (methacycline hydrochloride) has a broad spectrum of antimicrobial action.
Cefotaxime has a broad spectrum of antimicrobial action and is destroyed by cephalosporinase.
Carbapenem group (imipenem) has a broad spectrum of antimicrobial action.
Macrolide group (oleandomycin) has a narrow spectrum of action and is lowly toxic.
Aminoglycoside group (streptomycin) has a broad spectrum of antimicrobial action and is ototoxic.
Semisynthetic macrolides (roxithromycin) have a narrow spectrum of action and are lowly toxic.

Sulfonamide Drugs

Topical use (sulfacyl sodium) is used for competitive antagonism with PABA.
Resorptive sulfonamide drugs (sulfalene, etazol, urosulfan) are used for bronchitis, pneumonia, urinary tract infections, and biliary tract infections.
Sulfonamide drugs acting in the intestinal lumen (phthalazole, sulgin, phthazine) are used for competitive antagonism with PABA.

Miscellaneous

Physostigmine has an effect on the eye: constricts pupils, reduces intraocular pressure, and causes a spasm of accommodation.
Anticholinesterase agents with reversible action (proserin, galantamine hydrobromide, physostigmine salicylate) block acetylcholinesterase and prevent the hydrolysis of acetylcholine.
Anticholinesterase drugs used in glaucoma (proserin, physostigmine, armin) block acetylcholinesterase and prevent the hydrolysis of acetylcholine.
