PHARMASEAL SCRUB CARE
Clinical safety rating: caution
Comprehensive clinical and safety monograph for PHARMASEAL SCRUB CARE (PHARMASEAL SCRUB CARE).
PHARMASEAL SCRUB CARE is a combination topical antiseptic containing chlorhexidine gluconate and isopropyl alcohol. Chlorhexidine binds to negatively charged bacterial cell walls, disrupting membrane integrity and causing leakage of intracellular contents. Isopropyl alcohol denatures bacterial proteins and dissolves lipids, leading to rapid cell death.
| Metabolism | Not systemically absorbed; does not undergo significant metabolism. |
| Excretion | Primarily renal excretion of unchanged chlorhexidine (<1%) and its metabolites via glomerular filtration; biliary/fecal elimination accounts for >90% as degraded products. |
| Half-life | Terminal elimination half-life is approximately 1.5–2 hours for chlorhexidine in plasma; prolonged to >24 hours in tissue compartments due to extensive protein binding and slow release. |
| Protein binding | Chlorhexidine is >99% bound to plasma proteins, primarily albumin and alpha-1-acid glycoprotein. |
| Volume of Distribution | Chlorhexidine has a large volume of distribution of approximately 2.5–3.0 L/kg, indicating extensive tissue binding and distribution beyond plasma. |
| Bioavailability | Oral bioavailability is <5% due to extensive first-pass metabolism and poor absorption; negligible systemic absorption from intact skin; minimal via mucous membranes. |
| Onset of Action | Topical: immediate within 30 seconds for bactericidal effect; surgical scrub: rapid reduction within 1–2 minutes. |
| Duration of Action | Topical: up to 6 hours on skin with persistent antimicrobial activity; surgical scrub: sustained for 3–4 hours post-application. |
No specific dosing; apply topical antiseptic as needed for surgical hand antisepsis; typical application: 5 mL per hand and forearm, scrub for 3-5 minutes, repeat as per institutional protocol.
| Dosage form | SPONGE |
| Renal impairment | No adjustment required; topical application with negligible systemic absorption. |
| Liver impairment | No adjustment required; topical application with negligible systemic absorption. |
| Pediatric use | No established pediatric dosing; use with caution and follow institutional guidelines for pediatric surgical antisepsis. |
| Geriatric use | No specific adjustment; apply as per standard protocol, considering skin fragility in elderly. |
| 1st trimester | Consult provider |
| 2nd trimester | Consult provider |

Clinical note
Comprehensive clinical and safety monograph for PHARMASEAL SCRUB CARE (PHARMASEAL SCRUB CARE).
| Breastfeeding | Systemic absorption is minimal after topical application. No data available on M/P ratio. Chlorhexidine is excreted into breast milk in negligible amounts after topical use, and isopropyl alcohol is rapidly metabolized. Risk to nursing infant is low. Avoid direct application to breast before feeding to prevent infant ingestion. |
| Teratogenic Risk | PHARMASEAL SCRUB CARE is a topical antiseptic containing chlorhexidine gluconate (4% w/v) and isopropyl alcohol (70% v/v). Systemic absorption is negligible with topical use. No teratogenic effects have been reported in animal studies or human case reports. Fetal risk is considered minimal across all trimesters when used as directed. |
■ FDA Black Box Warning
None
| Serious Effects |
Hypersensitivity to chlorhexidine or isopropyl alcohol; application to meninges, brain tissue, or middle ear; use in ophthalmic or otic surgery; use in patients with known or suspected allergy to any component.
| Precautions | For external use only. Avoid contact with eyes, ears, mouth, and mucous membranes. Do not use in patients with known hypersensitivity to chlorhexidine or isopropyl alcohol. Avoid pooling under tourniquets or occlusive dressings. Use with caution in patients with broken skin, burns, or open wounds. May cause chemical burns if allowed to pool. Keep away from flames and heat sources due to flammability of alcohol. |
Loading safety data…
| Fetal Monitoring | No specific maternal or fetal monitoring is required beyond standard prenatal care, given negligible systemic absorption. Caution in patients with known hypersensitivity to chlorhexidine or isopropyl alcohol. |
| Fertility Effects | No adverse effects on fertility reported in animal studies or human data. Topical application does not affect reproductive organs or hormone function. |
