Pharmacology for NEET PG and FMGE

Pharmacology is one of the highest-scoring subjects in NEET PG and FMGE — but also one of the most memorisation-heavy. The MedNext formulary is built with exam preparation in mind. Each drug entry highlights the exam-relevant points: unique adverse effects, contraindications that appear as MCQ stems, drug interaction questions, and the Essential Medicines List entries tested in FMGE.

High-yield pharmacology topics consistently tested in NEET PG include: beta-blocker selectivity and contraindications, ACE inhibitor side effects vs ARBs, antibiotic mechanisms and resistance, anticoagulant reversal agents, and the pharmacology of drugs used in obstetric emergencies. All are covered with clinical context in the formulary.

Frequently Asked Questions

Is this an Indian formulary or a UK/US one?

The MedNext formulary is primarily aligned with the Indian drug market and the NMC Essential Medicines List, while also covering international drugs used in PLAB and USMLE contexts. Adult dosing uses Indian prescribing conventions where these differ from UK/US guidelines.

Does the formulary check interactions automatically?

Yes. Enter any two drugs and the interactions checker displays clinically significant interactions with severity grading and management recommendations. The interactions database covers the most common and clinically important drug pairs.

Is paediatric dosing available for all drugs?

Paediatric dosing is provided where evidence exists and paediatric use is approved. For drugs without established paediatric dosing, this is clearly stated along with any age-specific cautions.

How often is the formulary updated?

The formulary is reviewed periodically and updated when significant new drug approvals, label changes, or guideline updates occur. The most recent update date is shown on individual drug entries.
