Drug Store Management

Direct answer
Every expired strip on a shelf is capital that died — and drug store management is the discipline that prevents exactly that death. The subject (the PCI D.Pharm core called Drug Store and Business Management) covers selecting and buying stock scientifically, storing it by schedule and temperature, controlling inventory with ABC, VED, EOQ and reorder-level techniques, dispensing through documented procedures, and staying inside the licensing law: Forms 20 and 20-B for retail and wholesale, 21 and 21-B where Schedule C products are handled. Inventory maths and legal storage rules carry the marks; layout and business sense carry the practice.
What you must remember
- Purchase cycle: indent or demand note, enquiry, comparative quotations, purchase order, receipt with goods receipt note, inspection and quarantine, then stocking against bin card entry.
- ABC analysis (Always Better Control) ranks items by annual money value: typically about 10 per cent of items (A) carry most of the value and get tight control; C items are numerous, cheap and loosely controlled.
- VED analysis ranks criticality — Vital, Essential, Desirable — and matters most in hospital stores, where a cheap vital item (adrenaline, insulin) must never stock out.
- EOQ = square root of (2DS/H), where D is annual demand, S is ordering cost per order and H is holding cost per unit per year — the order size that minimises total inventory cost.
- Reorder level = (average daily consumption × lead time) + safety stock; below it you have waited too long to order.
- Issue discipline: FIFO (first in, first out) by purchase date, and FEFO (first expiry, first out) by expiry date — FEFO is the safer rule for medicines.
- Storage language: "cold" 2-8 °C, "cool" 8-15 °C, protect from light, protect from moisture; cold-chain stock (insulin, vaccines, biologics) with continuous temperature logs.
- Schedule-wise segregation: Schedule X under double lock with register; Schedule H1 entries in a separate register retained three years; narcotics under NDPS records; expired and recalled stock in a locked, labelled rejection area pending destruction or return.
- Retail sale legally requires a registered pharmacist's supervision during working hours (Rule 65), and Schedule H, H1 and X medicines must not cross the counter without a valid prescription.
- Pricing: DPCO 2013 under the Essential Commodities Act, administered by the NPPA, fixes ceiling prices for scheduled (essential) medicines; generic substitution through Janaushadhi kendras supplies the affordability angle.
The inventory maths worked on a real shelf
Take a chemist shop selling 4,000 packs of a particular antacid a year. Each order placed costs about Rs 100 in paperwork and delivery, and holding one pack for a year costs about Rs 2 (capital, spoilage, space). EOQ = square root of (2 × 4,000 × 100 / 2) = square root of 400,000 ≈ 632 packs — order roughly 600 packs each time, about six or seven orders a year, and total cost is at its minimum. If the supplier takes 5 days to deliver and the shop sells 16 packs a day (4,000/250 working days), average consumption over lead time is 80 packs; add a safety stock of, say, 40 packs for demand swings, and the reorder level is 120 packs: when the shelf plus godown fall to 120, reorder.
Now lay ABC and VED across the same shop. A-items by value — chronic-therapy brands, insulin, specialty antibiotics — get daily counts and tight supplier terms. C-items — cotton, sachets, vitamins — get loose periodic review. VED cuts across the money ranking: adrenaline ampoules may be cheap but are Vital, so they sit in the never-stock-out list regardless of their ABC grade. The matrix of the two — an item both A and Vital is managed hardest of all — is the two-mark application question.
Where practice and papers both go wrong
The classic error is running a pharmacy on FIFO alone. Medicines are dated goods; the pack bought earlier may expire later, so FEFO — first expiry, first out — is the professional rule, with short-expiry stock flagged and fronted. The second error is buying on price without verifying credentials: stock must be sourced only from manufacturers or wholesalers holding valid licences (Forms 20-B/21-B), because the buyer's licence does not launder an unlicensed supply chain — and in spurious-drug cases, undocumented sourcing is the prosecution's first exhibit.
Third, the legal shortcuts: no pharmacist on duty while the shop runs, Schedule H antibiotics handed over the counter, or the Schedule X cupboard sharing its key with the regular store. Each converts a routine inspection into a prosecution. The management lesson and the law converge: documentation — purchase records, registers, temperature logs, stock books — is not clerical burden but the store's actual defence.
Frequently asked questions
Differentiate ABC and VED analysis.
ABC ranks items by annual consumption value for financial control (A items: few items, most value); VED ranks by criticality for availability (Vital items must never stock out) — hospitals use both together.
Define EOQ and write its formula.
The order quantity minimising combined ordering and holding costs: EOQ = square root of (2DS/H), with D annual demand, S cost per order, H holding cost per unit per year.
How is the reorder level calculated?
Average daily consumption multiplied by lead time, plus safety stock — the stock level at which replenishment must be triggered to avoid a stock-out.
Why is FEFO preferred to FIFO in medicine stores?
Because expiry date, not purchase date, governs usability; issuing the earliest-expiring stock first minimises wastage even when arrivals were in a different order.
What are the storage requirements for Schedule X drugs?
Storage under double lock, a separate register of receipts and issues, prescriptions retained for two years, and sale only on a registered medical practitioner's prescription.
