Analytical challenges were overcome with the development of a new extraction procedure based on solid phase extraction to ensure efficient clonidine hydrochloride quantification.

Stability of -Acetylcysteine 60 mg/mL in Extemporaneously Compounded Injectable Solutions.

Background: -Acetylcysteine (NAC) administered by the IV route is the current treatment of choice for acetaminophen overdose. However, the protocol approved by health authorities in most countries has a complex dosing regimen, which leads to dosage errors in one-third of cases. Therefore, the Canadian Antidote Guide in Acute Care Toxicology and individual poison centres have begun to recommend a simplified regimen using continuous IV infusion.

Stability of Extemporaneously Compounded Suspensions of Trimethoprim and Sulfamethoxazole in Amber Plastic Bottles and Amber Plastic Syringes.

Background: Trimethoprim (TMP) and sulfamethoxazole (SMX) are widely used, in combination, to treat or prevent various infections. Unfortunately, no liquid oral formulation is currently available in Canada for patients who are unable to swallow tablets.

Objective: To evaluate the stability of suspensions of TMP and SMX (8 and 40 mg/mL, respectively) prepared in Oral Mix or Oral Mix SF vehicle (Medisca Pharmaceutique Inc) and stored for up to 90 days in amber plastic bottles or amber plastic syringes at 5°C or 25°C.

Compatibility of Lactated Ringer's Injection With 94 Selected Intravenous Drugs During Simulated Y-site Administration.

To test the compatibility of intravenous (IV) lactated Ringer's injection (LR) with 94 injectable (IV) drugs during simulated Y-site administration. Ninety-four IV drugs were investigated for compatibility with LR (Baxter). Each sample was prepared in duplicate and performed at room temperature.

Stability of Extemporaneously Prepared Acetazolamide Oral Suspensions at Two Temperatures.

Objectives: Some drugs need to be compounded by the pharmacist before being administered to the patient. A study was conducted to determine the stability of acetazolamide suspensions in 2 different vehicles (Oral Mix and Oral Mix Sugar Free [SF]) from bulk drug and tablets at 2 different temperatures and in 2 different containers (amber plastic bottles and clear plastic syringes).

Methods: Acetazolamide suspensions (25 mg/mL) were prepared from bulk drug or tablets.

Stability of Methadone Hydrochloride for Injection in Saline Solution.

Background: Until October 2014, methadone hydrochloride for injection (10 mg/mL) was available in Canada through Health Canada's Special Access Programme. Diluted to 5 mg/mL in saline, it was used in pediatrics for acute and cancer-related pain. More recently, the department of pharmacy of the Centre hospitalier universitaire Sainte-Justine in Montréal, Quebec, proposed compounding a solution of methadone hydrochloride for injection (5 mg/mL) from bulk powder and saline solution for pediatric administration.
