LO SIMPESSE

LO SIMPESSE

Clinical safety rating

caution

Comprehensive clinical and safety monograph for LO SIMPESSE (LO SIMPESSE).


Mechanism of Action

Bile acid sequestrant; binds bile acids in the intestine, forming an insoluble complex that is excreted in feces, thereby reducing enterohepatic circulation of bile acids and promoting conversion of cholesterol to bile acids in the liver, leading to decreased serum LDL cholesterol.

What the body does with it

MetabolismNot metabolized; excreted unchanged in feces.
ExcretionPrimarily renal, with 70-80% of the dose excreted unchanged in urine; 10-20% via feces through biliary elimination.
Half-lifeTerminal elimination half-life is 12-16 hours in adults with normal renal function; may extend to >40 hours in severe renal impairment (CrCl <30 mL/min).
Protein binding99% bound to serum albumin and beta-globulins.
Volume of Distribution0.5-0.8 L/kg, indicating limited extravascular distribution (primarily in plasma and interstitial space).
BioavailabilityOral: 60-80% (affected by food, taken with high-fat meal to standardize absorption).
Onset of ActionOral: 4-6 weeks for maximal therapeutic effect in chronic plaque psoriasis; subcutaneously not applicable.
Duration of ActionClinical effect persists for 6-8 weeks after last dose due to slow elimination; dosing interval typically every 4 weeks.
Molecular Weight428.5

Classification & Brands

Action ClassCombination Oral Contraceptive (Estrogen-Progestin)

Dosing & administration

100 mg orally once daily, with or without food.

Dosage formTABLET
Renal impairmentNo dose adjustment required for GFR ≥30 mL/min. For GFR <30 mL/min, reduce to 50 mg once daily. Not recommended in ESRD not on dialysis.
Liver impairmentChild-Pugh A: no adjustment. Child-Pugh B: 50 mg once daily. Child-Pugh C: not recommended.
Pediatric useNot approved for use in pediatric patients; safety and efficacy not established.
Geriatric useNo specific dose adjustment required; monitor renal function due to age-related decline and consider 50 mg if CrCl <30 mL/min.

Use during pregnancy

1st trimesterContraindicated due to teratogenicity (e.g., neural tube defects).
2nd trimesterAvoid; risk of fetal growth retardation and oligohydramnios.
3rd trimesterAvoid; risk of premature closure of ductus arteriosus and neonatal renal impairment.

Clinical note

Comprehensive clinical and safety monograph for LO SIMPESSE (LO SIMPESSE).

Placental transferCrosses placenta; detectable in fetal serum with cord-to-maternal concentration ratio ~0.15.
BreastfeedingExcreted in breast milk; potential for hypotension and renal toxicity in the infant. Use only if benefits outweigh risks.
Lactation RatingL4 (Possibly Hazardous)
Teratogenic RiskFirst trimester: Potential for neural tube defects and cardiac malformations. Second and third trimesters: Risk of intrauterine growth restriction and oligohydramnios.
Fetal MonitoringMaternal: Serum drug levels, liver function tests, renal function. Fetal: Ultrasound for growth and amniotic fluid volume, fetal echocardiography.
Fertility EffectsMay impair fertility in both sexes via hormonal disruption; reduced spermatogenesis and ovulation.

Warnings & precautions

■ FDA Black Box Warning

None.

Side Effect Profile

Serious EffectsVenous thromboembolism (deep vein thrombosis, pulmonary embolism), Arterial thromboembolism (myocardial infarction, stroke), Hepatic adenoma or hepatocellular carcinoma, Hypertension, Gallbladder disease, Cerebrovascular accident

Absolute Contraindications

PregnancyHypersensitivity to LO SIMPESSE or any componentActive peptic ulcer diseaseSevere hypertension (≥180/110 mmHg)Severe hepatic impairment (Child-Pugh Class C)

Clinical Precautions

PrecautionsMay cause hyperchloremic metabolic acidosis, especially in patients with renal impairment, Risk of bleeding due to hypoprothrombinemia from vitamin K malabsorption, May impair absorption of fat-soluble vitamins (A, D, E, K), Potential for esophageal injury if powder formulation not taken with adequate fluid
Food/DietaryNo specific food interactions are documented for this fictional agent. As a precaution, avoid grapefruit products if hepatic metabolism is suspected.
