Where possible prophylaxis should be started 2-3 weeks before travel to enable any adverse reactons to be identfed before expo- sure (over three-quarters of adverse reactons occur by the third dose) and should be contnued for 4 weeks afer last exposure generic rabeprazole 10 mg on-line chronic gastritis forum. It should be used in early pregnancy only if alternatve drugs are either not available or unlikely to be efectve and when it is impractcable for the woman to leave the endemic area cheap 20 mg rabeprazole overnight delivery gastritis symptoms worse night. Proguanil, a predominantly tssue schizontcide with litle blood schizontcidal actvity, is a causal prophylactc agent since it is actve against pre-erythrocytc intrahepatc forms, partcularly of P. Proguanil is used for prophylaxis with chlo- roquine in areas where there is resistance to chloroquine but a low risk of infecton as it may give some protecton against and may alleviate symptoms if an atack occurs. Proguanil and chloroquine may also be used prophylactcally in areas of high risk or mult-drug resistance as a second choice where mefo- quine is not appropriate. There is no evidence that proguanil is harmful in prophylactc doses during pregnancy. Because of the vulnerablility of preg- nant women to falciparum malaria, it should be used at full prophylactc dosage wherever the disease is prevalent and likely to be responsive to proguanil, if chloroquine is not avail- able or with chloroquine, if the later alone is unlikely to be efectve. Dose Oral Adult- Immediately 600 mg, afer 6 h 300 mg followed by 300 mg daily for 2 days. Child- 10 mg/kg body weight followed by 5 mg/kg body weight afer 6 h, thereafer once a day for 2 days. Contraindicatons Severe haematologic distress or gastrointestnal distress; eye dysfuncton; liver disease. Severe infectons including refractory urinary tract infecton: 200 mg daily can be used. Early syphilis: 100 mg twice daily for 14 days and for latent syphilis 200 mg twice daily for 28 days is used. Uncomplicated genital Chlamydia, non- gonococcal urethrits: 100 mg twice daily for 7 days.

Editorial comments • The drug of choice for male patients after a completed stroke is aspirin. There are some studies suggesting that ticlopidine may be slightly more effective in female patients. Mechanism of action: Competitive blocker of β-adrenergic receptors in heart, blood vessels, and eyes. Susceptible organisms in vivo: Staphylococci (penicillinase and nonpenicillinase), Staphylococcus epidermidis, Acinetobacter sp, Citrobacter sp, Enterobacter sp, Escherichia coli, Klebsiella sp, Proteus sp, Providencia sp, Pseudomonas sp, Serratia sp. Warnings/precautions • Use with caution in patients with renal disease, neuromuscular disorders (eg, myasthenia gravis, parkinsonism), hearing disor- ders. Clinically important drug interactions • Drugs that decrease effects/toxicity of aminoglycosides: peni- cillins (high dose), cephalosporins. Parameters to monitor • Monitor peak and trough serum levels 48 hours after beginning therapy and every 3–4 days thereafter as well as after chang- ing doses. If serum creatinine increases by more than 50% over baseline value, it may be advisable to dis- continue drug treatment and use a less nephrotoxic agent, eg, a quinolone or cephalosporin. Blocks myocardial excitability by reducing membrane conductance of sodium and potassium ions. Adjustment of dosage • Kidney disease: Creatinine clearance <30 mL/min: 50% of normal dose should be administered.
