# Citral (Note: Likely referring to Citrate salts or misinterpreted input)
## Overview
"Citral" is not a standard pharmaceutical drug entity. It is a naturally occurring terpene aldehyde found in essential oils (e.g., lemongrass). If you intended to inquire about **Sodium Citrate** (typically used as an alkalinizing agent or anticoagulant) or **Potassium Citrate**, please clarify. The following addresses **Sodium Citrate** (systemic alkalinization).
## Primary Indications
* Systemic alkalinization (e.g., metabolic acidosis treatment).
* Prophylaxis against acid aspiration in obstetric/surgical settings (e.g., Bicitra).
* Anticoagulant (in blood collection tubes).
## Adult Dosing
* **Systemic Alkalinization:** 15–30 mL of oral solution (contains ~1–2 mEq/mL sodium citrate) diluted in water, 4 times daily. Maximum dose varies by serum bicarbonate goals.
* **Aspiration Prophylaxis:** 15–30 mL orally 15–30 minutes prior to anesthesia. Do not exceed 30 mL.
## Pediatric Dosing
* **Systemic Alkalinization:** 5–15 mL (diluted) orally 4 times daily.
* *Note:* Dosing is highly dependent on serum bicarbonate levels and pediatric age/weight; consult institutional protocols or a pediatric nephrologist.
## Dose Adjustments
* **Renal Impairment:** Use with extreme caution. Contraindicated in patients with severe renal failure (risk of sodium/citrate accumulation).
* **Hepatic Impairment:** No specific adjustment, but use caution due to potential fluid retention.
## Contraindications
* Severe renal impairment (CrCl <30 mL/min).
* Severe heart failure or hypertension (due to high sodium load).
* Untreated Addison’s disease.
* Hyperkalemia (if utilizing potassium citrate formulations).
## Adverse Effects
* **Gastrointestinal:** Diarrhea, nausea, vomiting, abdominal cramps.
* **Metabolic:** Fluid overload, edema, hypernatremia, metabolic alkalosis.
* **Neurological:** Irritability or tetany (secondary to rapid changes in serum calcium/alkalization).
## Key Drug Interactions
* **Aluminum salts:** Citrates increase aluminum absorption; may lead to neurotoxicity in renal patients.
* **Potassium-sparing diuretics/ACEIs/ARBs:** Use caution; may exacerbate electrolyte imbalances.
* **Enteric-coated drugs:** Alkalinization of the stomach may cause premature dissolution of enteric coatings, leading to gastric irritation.
## Monitoring
* Serum electrolytes (Sodium, Potassium, Chloride, Bicarbonate/CO2).
* Serum creatinine/BUN.
* Blood pressure (secondary to fluid retention).
* Clinical signs of fluid overload (edema, pulmonary crackles).
## Clinical Pearls
* Citrate is metabolized to bicarbonate; effectiveness relies on intact hepatic function.
* Always dilute oral solutions in water to prevent mucosal irritation and GI distress.
* "Citral" (the terpene) is often used as a flavoring/fragrance agent and is generally recognized as safe (GRAS) by the FDA, but it is not a therapeutic drug.
