Drug Study - Phenobarbital Sodium

Luminal Sodium
Action:
Long-acting barbiturate. Sedative and hypnotic effects of barbiturates appear to be due primarily to interference with impulse transmission of cerebral cortex by inhibition of reticular activating system. CNS depression may range from mild sedation to coma, depending on dosage, route of administration, degree of nervous system excitability, and drug tolerance. Initially, barbiturates suppress REM [...]

Drug Study - Furosemide

Fumide , Furomide , Lasix, Luramide
Action:
Rapid-acting potent sulfonamide “loop” diuretic and antihypertensive with pharmacologic effects and uses almost identical to those of ethacrynic acid. Exact mode of action not clearly defined; decreases renal vascular resistance and may increase renal blood flow.
Classification:
ELECTROLYTIC AND WATER BALANCE AGENT; LOOP DIURETIC
Indication:

Treatment of edema associated with CHF, cirrhosis of liver, [...]

Drug Study - Albuterol

Salbutamol, Ventolin, Ventolin Rotocaps, Volmax
Action:
Synthetic sympathomimetic amine and moderately selective beta2-adrenergic agonist with comparatively long action. Acts more prominently on beta2 receptors (particularly smooth muscles of bronchi, uterus, and vascular supply to skeletal muscles) than on beta1 (heart) receptors. Minimal or no effect on alpha-adrenergic receptors. Inhibits histamine release by mast cells.
Classifications:
autonomic nervous system agent; [...]

Drug Study - Folic Acid

Action:
Vitamin B complex essential for nucleoprotein synthesis and maintenance of normal erythropoiesis. Acts against folic acid deficiency that impairs thymidylate synthesis and results in production of defective DNA that leads to megaloblast formation and arrest of bone marrow maturation.
Classification:
Vitamin B9
Indication:
Folate deficiency, macrocytic anemia, and megaloblastic anemias associated with malabsorption syndromes, alcoholism, primary liver disease, inadequate [...]

Drug Study - Trimethoprim-Sulfamethoxazole (TMP-SMZ)

Bactrim, Co-Trimoxazole, Septra
Action:
Fixed combination of sulfamethoxazole (SMZ), an intermediate acting antiinfective sulfonamide, and trimethoprim (TMP), a synthetic antiinfective. Both components of the combination are synthetic folate antagonist antiinfectives. Mechanism of action is principally enzyme inhibition, which prevents bacterial synthesis of essential nucleic acids and proteins.
Classifications:
antiinfective; urinary tract agent; sulfonamide
Indication:

Pneumocystis carinii pneumonitis, Shigellosis enteritis, and [...]

Drug Study - Losartan Potassium

Cozaar
Action:
Angiotensin II receptor (type AT1) antagonist acts as a potent vasoconstrictor and primary vasoactive hormone of the renin–angiotensin–aldosterone system.
Classifications:
cardiovascular agent; angiotensin ii receptor antagonist; antihypertensive
Indication:
Hypertension

Drug Study - Catopril

Capoten
Action:
Lowers blood pressure by specific inhibition of the angiotensin-converting enzyme (ACE). This interrupts conversion sequences initiated by renin that lead to formation of angiotensin II, a potent endogenous vasoconstrictor. ACE inhibition alters hemodynamics without compensatory reflex tachycardia or changes in cardiac output (except in patients with CHF). Peripheral vascular resistance is lowered by vasodilation. [...]

Drug Study - Clonidine Hydrochloride

Catapres, Catapres-TTS, Dixaril , Duraclon
Action:
Centrally acting antiadrenergic derivative. Stimulates alpha2-adrenergic receptors in CNS to inhibit sympathetic vasomotor centers. Central actions reduce plasma concentrations of norepinephrine. It decreases systolic and diastolic BP and heart rate. Orthostatic effects tend to be mild and occur infrequently. Also inhibits renin release from kidneys..
Classifications:
cardiovascular agent; central-acting antihypertensive; analgesic
Indication:
Step 2 drug [...]

Drug Study - Ranitidine

by: ishi21, RN
Zantac, Zantac EFFERdose, Zantac GELdose, Zantac-75
Action:
Potent anti-ulcer drug that competitively and reversibly inhibits histamine action at H2-receptor sites on parietal cells, thus blocking gastric acid secretion. Indirectly reduces pepsin secretion but appears to have minimal effect on fasting and postprandial serum gastrin concentrations or secretion of gastric intrinsic factor or mucus
Classifications:
GASTROINTESTINAL AGENT; ANTISECRETORY [...]

Drug Study - Dopamine Hydrochloride

by: ishi21, RN
Dopastat, Intropin, Revimine

Action:
Naturally occurring neurotransmitter and immediate precursor of norepinephrine. Major cardiovascular effects produced by direct action on alpha- and beta-adrenergic receptors and on specific dopaminergic receptors in mesenteric and renal vascular beds.
Classifications:
AUTONOMIC NERVOUS SYSTEM AGENT; ALPHA- AND BETA-ADRENERGIC AGONIST (SYMPATHOMIMETIC)
Indication:
To correct hemodynamic imbalance in shock syndrome due to MI (cardiogenic shock), [...]
