Prednisolone is a glucocorticoid used to treat adrenocortical insufficiency, inflammatory conditions, and some cancers.

Prednisolone is indicated to treat endocrine, rheumatic, and hematologic disorders; collagen, dermatologic, ophthalmic, respiratory, and gastrointestinal diseases; allergic and edematous states; and other conditions like tuberculous meningitis.

How Siogat P works

The bactericidal action of Gatifloxacin results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, and recombination.

The short term effects of corticosteroids are decreased vasodilation and permeability of capillaries, as well as decreased leukocyte migration to sites of inflammation. Corticosteroids binding to the glucocorticoid receptor mediates changes in gene expression that lead to multiple downstream effects over hours to days.

Glucocorticoids inhibit neutrophil apoptosis and demargination; they inhibit phospholipase A2, which decreases the formation of arachidonic acid derivatives; they inhibit NF-Kappa B and other inflammatory transcription factors; they promote anti-inflammatory genes like interleukin-10.

Lower doses of corticosteroids provide an anti-inflammatory effect, while higher doses are immunosuppressive. High doses of glucocorticoids for an extended period bind to the mineralocorticoid receptor, raising sodium levels and decreasing potassium levels.

Side Effects

Gatifloxacin is generally well tolerated. The most common side effects that can occur while taking this drug are usually mild and include nausea, vomiting, stomach pain, diarrhea, dizziness,and headache .

Toxicity

The intraperitoneal LD₅₀ in rats is 2g/kg and 65mg/kg in mice. The subcutaneous LD₅₀ in rats is 147mg/kg and >3500mg/kg in mice. The oral LD₅₀ in mice is 1680mg/kg. In humans, the oral TDLO in men is 9mg/kg/2W and in women is 14mg/kg/13D.

Patients experiencing an overdose of prednisolone may present with gastrointestinal disturbances, insomnia, and restlessness. Overdose of oral prednisolone may be treated by gastric lavage or inducing vomiting if the overdose was recent, as well as supportive and symptomatic therapy. Chronic overdosage may be treated by dose reduction or treating patients on alternate days. An overdose by the ophthalmic route is not expected to cause problems.

Precaution

Gatifloxacin should be administered with caution in the presence of renal insufficiency.

Volume of Distribution

A 0.15mg/kg dose of prednisolone has a volume of distribution of 29.3L, while a 0.30mg/kg dose has a volume of distribution of 44.2L.

Elimination Route

Well absorbed from the gastrointestinal tract after oral administration with absolute bioavailability of gatifloxacin is 96%

Oral prednisolone reaches a C_max of 113-1343ng/mL with a T_max of 1.0-2.6 hours. Oral prednisolone is approximately 70% bioavailable.

Half Life

7-14 hours

Prednisolone has a plasma half life of 2.1-3.5 hours. This half life is shorter in children and longer in those with liver disease.

Clearance

A 0.15mg/kg dose of prednisolone has a clearance of 0.09L/kg/h, while a 0.30mg/kg dose has a clearance of 0.12L/kg/h.

Elimination Route

Prednisolone is over 98% eliminated in urine.

Pregnancy & Breastfeeding use

Pregnancy: Gatifloxacin should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus.

Lactation: It is not known whether Gatifloxacin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when gatifloxacin is administered to a nursing woman.

Contraindication

Gatifloxacin is contraindicated in patients with a history of hypersensitivity of Gatifloxacin, quinolone antimicrobial agents, or any other components of this product.

Special Warning

Renal Impaired patient:

• Creatinine Clearance 40 mL/min: 400 mg every day.
• Creatinine Clearance < 40 mL/min: 400 mg 200 mg every day.

Dialysis patients:

• Hemodialysis: 400 mg 200 mg every day.
• Continuous peritoneal dialysis: 400 mg 200 mg every day.

Pediatric use: The safety and effectiveness of Gatifloxacinacin in pediatric populations (<18 years of age) have not been established.

Acute Overdose

Gatifloxacin exhibits a low potential for acute toxicity in animal studies. In the event of acute oral overdose, the stomach should be emptied by inducing vomiting or by gastric lavage. The patient should be carefully observed (including ECG monitoring) and given symptomatic and supportive treatment. Adequate hydration should be maintained.
