Description

Documented in source

Clear colourless solution.

Use and action

Documented in source

Barbiturate antiepileptic/sedative.
Active-drug context from another product’s labelling; it does not establish stability or dosing of this compounded preparation.

References: [2]

Specifications

Documented in source

Clear and colourless. Reject if yellowing or precipitation occurs.

Light

Not established

No specific information is established by the consulted sources. Complete this before local approval where critical to this preparation.

References: [1]

Air

Not established

No specific information is established by the consulted sources. Complete this before local approval where critical to this preparation.

Water and solubility

Partial evidence

Glycerol is miscible with water. This does not establish product microbiological stability.

References: [3]

Humidity

Partial evidence

Glycerol is hygroscopic; limit raw-material exposure to moisture.

References: [3]

Temperature

Partial evidence

For the finished product the source specifies:
Amber plastic bottle, ≤25 °C. Do not refrigerate: precipitation risk.

References: [1]

pH and related incompatibilities

Not established

No specific information is established by the consulted sources. Complete this before local approval where critical to this preparation.

References: [1]

Other incompatibilities

Partial evidence

Glycerol: hazardous reaction with strong oxidising agents.

References: [3]

Ingredient-specific information

Partial evidence

Glycerol: Glycerol is hygroscopic; limit raw-material exposure to moisture.
These are selected facts for identified ingredients; relevant sensitivities and incompatibilities are detailed in the corresponding fields. This is not a complete SDS for every material.

References: [3]

Personal protective equipment

Partial evidence

Complete formula-specific PPE is not specified. Select gloves, eye protection and exposure controls using the exact materials’ SDS and the local risk assessment.
Supplementary AEMPS framework: clean long-sleeved laboratory clothing, hair covering and dedicated footwear/overshoes. Powder handling requires suitable eye/respiratory protection; change gloves with activity or damage. Select the exact type/material using SDS and risk assessment.

Risks and precautions

Partial evidence

A complete formula-specific hazard classification is not established. Assess potency, dust/aerosol, allergens, solvents, microbial risk and cross-contamination using the actual materials and process. Absence of a flag does not establish absence of hazard.

Compounding conditions

Partial evidence

Follow the addition sequence, temperatures and times stated under Preparation Procedure. The specific monograph is not a complete qualification of the local facility/equipment.

BUD rationale

Documented in source

7 days, as revised on 11 February 2025.
The source period applies to its exact composition, method and packaging. It is not this batch’s expiry date and cannot be transferred to another vehicle/strength. Calculate the actual date in the blank batch record.

Bases and dependencies

Partial evidence

No separate base is identified in the dependency register. Check any commercial vehicles/compound excipients listed in the formula.

Preparation procedure

Documented in source

Weigh sodium salt, wet with glycerol and add water progressively. Transfer quantitatively, make to 40 mL, mix and package.

References: [1]

Observations

Documented in source

Use phenobarbital sodium powder, not phenobarbital free acid or tablets. Water must meet the source therapeutic-use specification and applicable local quality requirements.

References: [1]

Packaging

Documented in source

Amber plastic bottle as specified by the sheet.

References: [1]

Quality control

Partial evidence

Clear and colourless. Reject if yellowing or precipitation occurs.
