Medicines prepared in the form of tablets or pills are known as Vaṭi and GutikāGuṭikā. These are made of one or more drugs of plant, animal or mineral origin. GutikāGuṭikā, Vataka, Modaka, Piṇḍi and Vaṭi are synonymous terms used in classics for Vaṭi.

==Preparation InvolvesMethod of preparation==*The drugs of plant origin are dried and made into fine powders, separately. The minerals are made into bhasma or sindura, unless otherwise mentioned. In cases where pārada and gandhaka are mentioned, Kajjalī is made first and other drugs added, one by one, according to the formula. These are put into a khalva and ground to a soft paste with the prescribed fluids. When more than one liquid is mentioned for grinding, they are used in succession. When the mass is properly ground and is in a condition to be made into pills, gandha dravyas, like kasturi, karpura, which are included in the formula, are added and ground again. *The criterion to determine the final stage of the formulation before making pills is that it should not stick to the fingers when rolled. Pills may be dried in shade or in sun as specified in the texts. *In cases where sugar or jaggery (guda) is mentioned, pāka of these should be made on mild fire and removed from the oven. The powders of the ingredients are added to the pāka and briskly mixed. When still warm gutikas should be rolled and dried in shade.<ref name="AYURVEDIC PHARMACOPOEIA OF INDIA"/> ==Characteristics==*The Lehya should neither be hard nor a thick fluid. When pulp of the drugs is added and ghee or oil is present in the preparation, this can be rolled between the fingers. When metals are mentioned, the bhasmas of the metals are used. In case of drugs like [[Bhallātaka]], purification process is to be followed. ==Preservation==*The Lehya should be kept in glass or porcelain jars. It can also be kept in a metal container which does not react with it. Normally, Lehyas should be used within one year.<ref name="The Ayurvedic formulary of India"/>
