Pills and Tablets

Part of Pharmacy and Apothecary

Making solid oral dosage forms by hand — the traditional pharmacy pill and its practical formulation without industrial equipment.

Why This Matters

Pills and tablets solve specific problems that liquids cannot. A patient who must carry medicine on a journey cannot bring liters of decoction. A medicine with an intolerably bitter taste becomes manageable when enclosed in a pill that passes quickly over the taste buds. A powder that would be irritating to mucosal tissues in the mouth travels safely to the stomach in pill form. Some medicines require slow, sustained release that a liquid cannot provide but a dense pill can approximate.

The hand-rolled pill is one of the oldest pharmaceutical dosage forms. It requires no machinery, only powdered medicine and a binder. Ancient Egyptian, Greek, and Ayurvedic practitioners made pills. Medieval apothecaries made pills as a significant portion of their daily work. The techniques that worked for thousands of years remain valid.

Modern “tablets” are compressed pills made by machinery — the same principle, requiring industrial equipment you will not have. The traditional pill, rolled by hand from a pliable mass, is fully practical in a post-collapse apothecary and can achieve doses accurate to ±10% with care — adequate for most non-critical medicines.

Components of a Pill

Every pill has two components: the active ingredient(s) and a binder that holds them together.

Active ingredients: The medicinal substance, typically as a dry powder. This is prepared by grinding dried plant material to a fine, consistent powder using a mortar and pestle. Sieve through fine cloth to remove coarse particles. The finer the powder, the better it binds and the faster it dissolves in the stomach.

Binders: Substances that make the powder pliable enough to shape and hold its form when dry. Several options:

Binder	Amount	Properties
Honey	1-3 parts honey to 5 parts powder	Adds preservation, sweetness, antimicrobial activity. Natural and widely available.
Gum tragacanth or gum arabic	Dissolved in water, added drop by drop	Traditional pharmacy binder; provides very firm pills
Bread crumb (fresh)	Mix equal weights	Practical improvisation; produces adequate pills but less shelf-stable
Beeswax (melted)	5-10% of pill weight	Very stable; dissolves slowly — use only for preparations where delayed release is desired
Molasses	1-2 parts to 5 parts powder	Similar to honey, somewhat less effective binder
Mucilage of plantain or marshmallow root	Made fresh	Cold-infuse seeds or roots, use the thick liquid as binder

Pill-Making Procedure

Equipment:

• Mortar and pestle
• Balance scale
• Smooth, clean rolling surface (marble, ceramic tile, or polished wood)
• Pill roller (a smooth flat-bottomed rod — glass works well)
• Wax paper or dried leaves for separating pills during drying

Procedure:

1. Powder the active ingredient: Grind to as fine a powder as the mortar and pestle can achieve. Sieve through fine cloth, discard any remaining coarse material, and grind again.

2. Calculate your batch: Decide how many pills to make and what dose each pill should contain. Weigh out the total active ingredient needed for the batch. Example: 50 pills at 250 mg each = 12.5 grams total active ingredient.

3. Add binder slowly: Create a small well in the center of your powder in the mortar. Add binder drop by drop or in small amounts while working the mixture with a pestle or your fingers. The mass should become cohesive — like stiff dough — but not sticky. If it becomes too wet and sticky, add more powder. If it won’t hold together, add more binder.

4. Test consistency: Take a small amount and roll it between your palms. It should form a smooth sphere without cracking or sticking to your hands. Adjust consistency as needed before proceeding.

5. Form the mass into a cylinder: Roll the entire pill mass into a long, even cylinder on your smooth surface. The diameter of the cylinder should equal the diameter of the intended pill — typically 8-12 mm for standard pills.

6. Cut into doses: Using a blade, cut the cylinder into uniform pieces. Each piece becomes one pill. Cut lengths should be equal to the diameter (producing spheres rather than discs). Weigh several pieces to verify consistency — you are aiming for ±10% of target dose weight.

7. Round the pills: Roll each cut piece between your palms to form a sphere. Work quickly before the mass dries.

8. Dry: Arrange pills on a clean surface in a single layer. Allow to dry in a warm location with good air circulation for 24-48 hours. Do not stack until fully dry.

9. Coat (optional): Rolling finished pills in powdered licorice root, cocoa, or carob powder reduces stickiness and improves palatability.

Weight Verification and Dose Accuracy

After drying, weigh a representative sample of pills (at least 10%) individually. Calculate:

• Average weight
• Maximum and minimum weight
• Percentage deviation from target

If any pill deviates more than 15% from target weight, or if average weight is more than 5% from target, the batch quality is insufficient for potent medicines. Dissolve them and remake.

For medicines with narrow therapeutic windows, pre-weight verification is critical. For relatively safe preparations (herbal bitters, mild analgesics), 10-15% variation is acceptable.

Record the average pill weight in your dispensing log. When dispensing, note the number of pills and the average weight per pill.

Special Pill Formulations

Enteric pills: Pills intended to survive stomach acid and dissolve in the intestines. Coat with beeswax (dip in melted beeswax, then cool) or with a shellac solution. The coating prevents gastric dissolution and reduces stomach irritation from irritating medicines.

Slow-release pills: More beeswax in the formulation (15-20%) slows dissolution. Useful for sustained action but makes dose timing less predictable.

Divided pills: For very small doses that are difficult to measure as individual pills, make larger pills and score them with a blade before drying so they can be broken in half. A 500 mg pill scored in half gives two 250 mg doses.

Layered pills: For combination formulas where two ingredients should not be mixed (e.g., one oxidizes the other), form a pill core of one ingredient and coat with a layer of the second. Niche application, but possible with patience.

Storage of Finished Pills

Properly dried and stored pills can last 6-24 months depending on ingredients. Store in:

• Airtight containers (glass, ceramic with fitted lid)
• Cool, dark location
• Away from moisture — a single damp pill can seed mold through an entire container

Layer between wax paper if containers are large. Label every container: preparation name, dose per pill, date made, lot number, expected expiry.

Signs of spoilage: mold growth (green, white, or black fuzz), crumbling that was not present when dry, unusual smell, or softening from moisture absorption. Discard any pills showing these signs.

The pill, humble as it appears, is one of the most practical tools in the apothecary’s toolkit precisely because it is simple, stable, and portable.
