Pregnancy & Lactation
Pregnancy Category: C
There are no adequate and well controlled studies of aerosolized pentamidine in pregnant women; a literature report indicated that pentamidine 4 mg/kg/day IV administered to pregnant rats was embryolethal; teratogenicity was not observed in this study. It is unknown whether aerosolized pentamidine crosses the placenta at clinically significant concentrations
Lactation: Not known if distributed in breast milk, discontinue drug or do not nurse
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Inhibits synthesis of DNA, RNA, phospholipids, protein by inhibiting oxidative phosphorylation and/or interfering with incorporation of nucleotides and nucleic acids into RNA and DNA
Pharmacokinetics
Half-Life: 5.8 hr (IV); 7-11 hr (IM)
Metabolism: Liver
Vdss: 286-1356 L (IV); 1658-3790 (IM)
Excretion: Urine (12%)
Administration
IV Incompatibilities
Y-site: aldesleukin, cefazolin, cefoperazone, cefotaxime, cefoxitin, ceftazidime, ceftriaxone, fluconazole, foscarnet, linezolid
IV Compatibilities
Solution: D5W, NS
Y-site: diltiazem, gatifloxacin, zidovudine
IV Preparation
Reconstitute w/ 3-5 mL SWI or D5W (do not use NS)
Reconstituted solutions (60-100 mg/mL) stable for 48 hr at room temp; keep between 22-30°C to prevent crystallization
For IV infusion, dilute in 50-250 mL D5W (stable at room temp for 24 hr)
IV/IM Administration
IM: deep IM using Z-track technique
IV: Slow infusion over 60-120 min
Pts should be in supine position
