Rash, usually in the frst 2 weeks, is the most common adverse efect; discontnue if severe rash with blistering, desquamaton, mucosal involvement or fever; if rash mild or moderate, may contnue without interrupton-rash usually resolves within 1 month. Child- 2 months to 8 years: 4 mg/kg body weight once a day for 14 days, if tolerated and no rash is observed increase to 4 mg/kg body weight two tmes a day. Contraindicatons Acute porphyria; severe hepatc impairment; post-exposure prophylaxis; breast feeding. Precautons Hepatc impairment (see below and Appen- dix 7a); history of chronic hepatts (greater risk of hepatc adverse efects), pregnancy (Appendix 7c) and lactaton (Appendix 7b); interactons (Appendix 6b, 6c). Potentally life-threatening hepatotoxicity including fatal fulminant hepatts reported usually occurring in frst 8 weeks; monitor liver functon before long-term treatment then every 2 weeks for 2 months then afer 1 month and then every 3-6 months; discontn- ue permanently if abnormalites in liver func- ton tests accompanied by hypersensitvity reacton (rash, fever, arthralgia, myalgia, lym- phadenopathy, hepatts, renal impairment, eosinophilia, granulocytopenia); suspend if severe abnormalites in liver functon tests but no hypersensitvity reacton-discontnue permanently if signifcant liver functon ab- normalites recur; monitor patent closely if mild to moderate abnormalites in liver func- ton tests with no hypersensitvity reacton. Rash, usually in frst 8 weeks, is most common adverse efect; incidence reduced if introduced at low dose and dose increased gradually; discontnue permanently if severe rash or if rash accompanied by blistering, oral lesions, conjunctvits, swelling, general malaise or hypersensitvity reactons; if rash mild or moderate may contnue without interrupton but dose should not be increased untl rash resolves. Patents should be told how to recognize hypersensitvity reactons and advised to seek immediate medical atenton if symptoms develop. Adverse Efects Rash including Stevens-Johnson syndrome and rarely, toxic epidermal necrolysis (see also Precautons above); hepatts or jaundice reported (see also Precautons above); nausea, vomitng, abdominal pain, diarrhoea, headache, drowsiness, fatgue, fever; hypersensitvity reactons (may involve hepatc reactons and rash, see Precautons above); anaphylaxis, angioedema, urtcaria also reported; granulocytopenia. Storage Store protected from light and moisture at a temperature not exceeding 30⁰C. Precautons Hepatc impairment (Appendix 7a); ensure adequate hydraton to reduce risk of nephro- lithiasis; diabetes mellitus; haemophilia; preg- nancy (see notes above and Appendix 7c); lactaton (Appendix 7b) (see notes above); metabolism of many drugs inhibited if admin- istered concomitantly; interactons (Appendix 6c, 6d); hyperbilirubinemia, tubulo-intersttal nephrits.

Acidic urine increases excretion of many noncatecholamines; alkaline urine slows excretion buy generic cephalexin 750 mg line bacteria background. Pharmacodynamics Noncatecholamines can be direct-acting, indirect-acting, or dual- acting (unlike catecholamines, which are primarily direct-acting). Those that selectively stimulate beta2 re- ceptors include albuterol, isoetharine, metaproterenol, and terbu- taline. Pharmacotherapeutics Noncatecholamines stimulate the sympathetic nervous system, producing a variety of effects in the body. Phenylephrine, for ex- ample, causes vasoconstriction and is used to treat hypotension in cases of severe shock. Adverse reactions to noncatecholamines Adverse reactions to noncate- • hypertension or hypotension cholamine drugs may include: • palpitations • headache • bradycardia or tachycardia • restlessness • irregular heart rhythm • anxiety or euphoria • cardiac arrest • irritability • cerebral hemorrhage • trembling • tingling or coldness in the arms • drowsiness or insomnia or legs • light-headedness • pallor or flushing • incoherence • angina. Here are a few examples of drugs that interact with noncatechol- amines: • Anesthetics (general), cyclopropane, and halogenated hydrocar- bons can cause arrhythmias. Hypotension can also occur if these drugs are taken with noncatecholamines that exert predominantly beta2 activity, such as terbutaline. When taken with other non- catecholamines, oxytocic drugs can cause hypertensive crisis or a stroke. Their action at these sites can be exerted by: • interrupting the action of adrenergic (sympathomimetic) drugs • reducing available norepinephrine • preventing the action of cholinergic drugs. Classified information Adrenergic blocking drugs are classified according to their site of action as: • alpha-adrenergic blockers (or alpha blockers) • beta-adrenergic blockers (or beta blockers). Alpha-adrenergic blockers Alpha-adrenergic blockers work by interrupting the actions of the catecholamines epinephrine and norepinephrine at alpha recep- tors.
