Ciprofloxacin Alcohol

Theophylline is a narrow therapeutic index drug with significant difference in bioavailability following oral administration. The half-life of the drug is increased by heart failure, cirrhosis and viral infections, in elderly patients, and by certain drugs, such as cimetidine, ciprofloxacin, oral contraceptives and fluvoxamine. The half-life is decreased in smokers, chronic alcoholism, and by certain drugs, such as phenytoin, rifampicin and carbamazepine.

Sustained-release formulations can produce stable serum concentrations with once or twice daily dosage. Therapeutic effects occur at blood levels > 5 mg/1, and side effects increase considerably at levels > 15 mg/1. Smoking, alcohol, anticonvulsants, and rifampicin induce the drug-metabolizing enzyme system in liver and reduce the half-life of theophylline. On the other hand, heart and liver failure, sustained fever, old age and drugs such as cimeti-dine, ciprofloxacin, and oral contraceptives reduce theophylline clearance and thereby increase serum concentrations. 

B) Acute alcohol withdrawal was precipitated by ciprofloxacin due to an alcohol-drug interaction. 

Displacement of GABA from its receptors by ciprofloxacin results in increased levels of the neu-roexcitatory transmitter and acute CNS toxicity. The neuroexcitation can range from irritability, confusion, and agitation to seizures and toxic psychosis. Ciprofloxacin has no interaction with alcohol. A disulfiramlike reaction (flushing, nausea, vomiting, and profuse sweating) is associated with alcohol and metronidazole. Avoid alcohol and metronidazole coadministration.

In contrast to ulcerative colitis, about 50% of patients with Crohn s colitis will respond to metronidazole given for up to 3 months, although adverse effects including alcohol intolerance, and peripheral neuropathy from such prolonged therapy often limit its use. The drug is also helpful in controlling perianal and small bowel disease and it decreases the incidence of anastamotic recurrence after surgery. Other antimicrobials, particularly ciprofloxacin may also be effective.

Ciprofloxacin does not significantiy affect the pharmacokinetics of aicohoi or the psychomotor performance observed with alcohol alone. There is an isoiated report of a cutaneous reaction to ciprofloxacin, which may have been precipitated by alcohol ingestion. 

A 3-day course of ciprofloxacin 500 mg twice daily had no significant effect on the pharmacokinetics of a single 30-g oral dose of alcohol (75 mL of vodka) in 12 healthy subjects, nor was the performance of a number of psychomotor tests affected. ... 

There is an isolated report of red blotches developing on the face and body of a tetraplegic patient receiving ciprofloxacin 250 mg twice daily, which developed within 10 minutes of drinking 2 cans of beer containing alcohol 4.7%. He did not feel unwell or drowsy and the blotches faded over a period of 30 minutes. Previous courses of ciprofloxacin had not produced any adverse effects and the same brand of alcohol caused no...

Ocular systems (Figure 7.5b) with application in the lower ophthalmic conjunctival sac for the controlled release of ciprofloxacin (pre- or post-operative treatment of topical infections, as well as conjimctivitis) were obtained from polyvinyl alcohol and sodium carboxymethylcellulose linking the two polymers by an esterification reaction between the hydroxyl groups of the polyvinyl alcohol and carboxyl groups of carboxy-methyl cellulose [47]. Membranes were obtained by the incorporation of the antibiotic into the polymer solution with the addition of glycerol as a plasticizer (in order to ensure the flexibility of the membrane). The advantage of using these polymers comes from their biocompatibility and from the fact that they are water soluble as the controlled release occms, the membrane is dissolved by the tear bed at 35"C temperature.
