PROCTOCORT

Clinical safety rating: caution

Comprehensive clinical and safety monograph for PROCTOCORT (PROCTOCORT).

How it works

PROCTOCORT (hydrocortisone acetate) is a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive effects. It binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine production.

What the body does with it

Metabolism	Hydrocortisone acetate is metabolized primarily in the liver via reduction and conjugation, forming inactive metabolites that are excreted renally. Topical use minimizes systemic absorption, thus hepatic metabolism is limited.
Excretion	Primarily hepatic metabolism; renal excretion of metabolites accounts for ~60-70%, with ~15-25% excreted in feces via biliary elimination. Unchanged drug in urine is negligible (<1%).
Half-life	Terminal elimination half-life is approximately 3.5 hours (range 2-5 hours) for triamcinolone acetonide. Clinical context: short half-life supports BID or TID dosing in topical and rectal administration.
Protein binding	Approximately 75-80% bound to plasma proteins, primarily albumin and corticosteroid-binding globulin (CBG).
Volume of Distribution	Volume of distribution is approximately 1.4 L/kg (range 1.2-1.7 L/kg). This reflects moderate tissue penetration and distribution into interstitial fluid.
Bioavailability	Rectal administration: systemic bioavailability is variable, estimated at 10-30% due to extensive first-pass metabolism in the liver. Topical application: minimal systemic absorption (<1% on intact skin; up to 5% on inflamed or damaged mucosa).
Onset of Action	Topical/rectal: clinical relief of inflammation and pruritus typically within 1-3 hours after application; maximum effect may require 1-3 days of regular use.
Duration of Action	Duration of anti-inflammatory effect is approximately 8-12 hours after single application. Clinical note: sustained symptom relief with BID dosing; resolution of acute hemorrhoidal symptoms may take 3-7 days.

Classification & Brands

Dosing & administration

Rectal: One 30 mg suppository twice daily (morning and evening) for 2-3 weeks, then taper down as needed. Alternatively, 1% cream or ointment applied rectally 3-4 times daily.

Dosage form	CREAM
Renal impairment	No dosage adjustment required for renal impairment.
Liver impairment	No specific guidelines; use caution in severe hepatic impairment due to potential corticosteroid accumulation.
Pediatric use	Safety and efficacy not established. Avoid use in children under 2 years. For older children, use lowest effective dose under medical supervision (e.g., 1% cream applied sparingly once or twice daily).
Geriatric use	Use lowest effective dose; monitor for increased systemic absorption (skin thinning, adrenal suppression) with prolonged use.

Breastfeeding

Topical hydrocortisone is excreted into breast milk in negligible amounts; M/P ratio is unknown. Short-term use of low-potency topical corticosteroids is considered compatible with breastfeeding. Avoid application to the breast area to prevent infant ingestion.

Teratogenic Risk

PROCTOCORT (hydrocortisone acetate) is a topical corticosteroid. Systemic absorption is minimal with topical use, but first trimester use should be avoided unless clearly needed. Animal studies have shown corticosteroids to be teratogenic, but no adequate human data. Second and third trimester use is generally considered low risk, though chronic high-dose exposure may cause intrauterine growth restriction and adrenal suppression in the neonate.

["Hypersensitivity to hydrocortisone or any component of the formulation.","Untreated fungal, bacterial, or viral infections at the application site."]

Clinical Precautions

Precautions

["Prolonged use may lead to skin atrophy, striae, or secondary infection.","Systemic absorption can cause reversible hypothalamic-pituitary-adrenal (HPA) axis suppression, especially with occlusive dressings or use on large body areas.","Avoid use in the presence of fungal or bacterial infections unless appropriately treated.","Not for ophthalmic use."]
