A standard prescription consists of the following parts:

• Prescriber Information: Name, address, registration number, and contact details of the doctor.
• Date: The date the prescription was written, which is essential for determining the validity of the order.
• Patient Information: Name, age, gender, and address of the patient to ensure correct identification.
• Superscription: Represented by the symbol 'Rx', meaning 'take thou' or 'you take'.
• Inscription: The core part containing the names and quantities of the ingredients (base, adjuvant, vehicle).
• Subscription: Directions to the pharmacist regarding the dosage form and number of doses to be prepared.
• Signatura (Sig): Instructions for the patient regarding the route of administration, dose, and frequency.
• Renewal Instructions: Details on whether the prescription can be refilled and how many times.
• Signature/Initials: The prescriber's signature or initials to authenticate the document.

United States Pharmacopoeia (USP): The USP is an official public standards-setting authority for all prescription and over-the-counter medicines, dietary supplements, and other healthcare products manufactured or sold in the United States. It provides legally recognized standards for identity, strength, quality, and purity of these substances. It is published annually and is essential for ensuring the safety and efficacy of pharmaceutical products in the US market.

Extra Pharmacopoeia (Martindale): The Extra Pharmacopoeia, commonly known as Martindale, is an internationally recognized reference work that provides comprehensive, unbiased, and evaluated information on drugs and medicines used throughout the world. Unlike official pharmacopoeias, it is not a legal standard but a clinical reference. It covers details on properties, actions, uses, dosage, and adverse effects of drugs, making it an invaluable resource for pharmacists and medical practitioners for clinical decision-making.
