Pharmacy Law and Ethics Reviewer for PLE Philippines 2026

By LisensyaPrep Team | Last Updated: April 2026 | 10-minute read

Pharmacy Law and Ethics is one of those PLE subjects where examinees either do very well because they paid attention to the legal framework during school, or do poorly because they assumed it was just memorization and skipped it.

The truth is somewhere in between. Yes, you need to know specific provisions of several laws. But what the PLE tests most is whether you understand the purpose behind those provisions and can apply them to real pharmacy practice scenarios.

This reviewer covers the major laws, regulations, and ethical principles that appear in the PLE.

Republic Act 5921: The Pharmacy Law of the Philippines

RA 5921, also known as the Pharmacy Act, is the foundational law governing the practice of pharmacy in the Philippines. It is one of the most heavily tested laws in this subject.

Scope of Pharmacy Practice Under RA 5921

The law defines the practice of pharmacy to include:

Republic Act 9502: Cheaper Medicines Act

RA 9502, the Universally Accessible Cheaper and Quality Medicines Act of 2008, is a landmark law that significantly changed pharmacy practice in the Philippines.

Key Provisions

Generic drug substitution: Licensed pharmacists are authorized to substitute a prescribed branded drug with a generically equivalent drug unless the prescribing physician writes "no substitution" on the prescription.

Duty to inform: When substituting, the pharmacist must inform the patient of the substitution, the reasons, and the price difference.

Pricing: The law empowers the government to impose maximum retail prices on essential medicines. The President may impose price controls during declared states of emergency.

Generic labeling: Drug manufacturers must include the generic name prominently on all labels, printed at least half the size of the brand name.

What PLE Questions Test in RA 9502

Most PLE questions on this law focus on the conditions for and process of drug substitution, and the pharmacist's responsibilities when exercising this authority. The key point: substitution is a pharmacist right and sometimes a duty, but patient consent and notification are required.

Republic Act 9165: Comprehensive Dangerous Drugs Act of 2002

RA 9165 is the primary law governing dangerous drugs in the Philippines and generates many PLE questions, particularly about prescription requirements for controlled substances and penalties for violations.

Drug Schedules

Under PDEA regulations implementing RA 9165, drugs are classified by schedule based on their potential for abuse and accepted medical use.

Schedule I: High abuse potential, no accepted medical use in the Philippines. Examples: heroin, LSD, ecstasy.

Schedule II: High abuse potential but with accepted medical use. Examples: morphine, fentanyl, methamphetamine (pharmaceutical grade), cocaine (topical anesthetic).

Schedule III, IV, V: Decreasing potential for abuse with accepted medical uses. Examples include benzodiazepines, mild opioid combinations.

Prescription Requirements for Controlled Substances

Schedule II drugs require a triplicate prescription form (S2 license). The prescribing physician must have a special license from the PDEA to prescribe Schedule II substances. The pharmacist must verify the validity of the S2 prescription before dispensing.

Key Pharmacist Responsibilities Under RA 9165

Food and Drug Administration (FDA) Philippines

The Philippine FDA (under Republic Act 9711, the FDA Act of 2009) is the regulatory body that oversees the safety and quality of food, drugs, cosmetics, and other health products.

Drug Registration: All pharmaceutical products sold in the Philippines must have a Certificate of Product Registration (CPR) from the FDA before they can be marketed. The CPR contains the approved indications, dosage, and labeling.

Good Manufacturing Practice (GMP): Pharmaceutical manufacturers must comply with GMP standards to receive and maintain their license to operate. GMP covers facility requirements, quality control, documentation, and personnel qualifications.

Adverse Drug Reaction (ADR) Reporting: Pharmacists and other healthcare professionals are encouraged to report adverse drug reactions to the FDA through the National Pharmacovigilance Program.

Professional Ethics for Pharmacists

Confidentiality

Patient medication records and health information are confidential. A pharmacist may not disclose this information without patient consent except when required by law (e.g., court order, public health reporting requirements).

Conflicts of Interest

A pharmacist must not allow financial relationships with drug manufacturers or distributors to influence their professional judgment about which drugs to recommend or dispense. Accepting gifts or incentives that could compromise professional judgment is an ethical violation.

Conscientious Objection

A pharmacist who has a moral objection to dispensing a specific medication (e.g., certain contraceptives) may decline, but must refer the patient to another pharmacist or pharmacy where the medication can be obtained without delay. The patient's access to legally prescribed medication must not be impeded.
