A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.

Dipeptidyl peptidase 4 inhibitors are oral antidiabetes agents that help control blood sugar levels in Type 2 diabetes patients. They inhibit the enzyme dipeptidyl peptidase 4 and regulate the levels of insulin the body produces after a meal. Dipeptidyl peptidase 4 inhibition results in increased activity of incretins, which inhibits glucagon release. This leads to increased insulin secretion, decreased gastric emptying and therefore decreased blood sugar levels.

Dopaminergic antiparkinsonism agents aim to replace dopamine or prevent the degradation of dopamine.

Antiparkinson drugs that aim to replace dopamine in the central nervous system, either release dopamine or mimic the action of dopamine. Drugs that replace dopamine are generally given with peripherally acting dopa carboxylase inhibitors, to prevent the metabolism of levodopa to dopamine peripherally. Dopamine receptor agonists bind to dopamine receptors and mimic the action of dopamine.

Selective monoamine oxidase (MAO-B) inhibitors bind to the enzyme MAO-B and prevent dopamine from being broken down.

Antiparkinson agents are used to treat Parkinson

Decongestants are sympathomimetic drugs that act by stimulating the alpha-adrenergic receptors. Decongestants are either taken orally or applied locally in the form of nasal sprays or drops. The decongestant effect is due to vasoconstriction of the blood vessels in the nose, sinuses, etc. The vasoconstriction effect reduces swelling or inflammation and mucus formation in the nasal passage and makes it easier to breath.

Anticonvulsants are drugs that prevent or reduce the severity and frequency of seizures in various types of epilepsy. The different types of anticonvulsants may act on different receptors in the brain and have different modes of action.

Two mechanisms that appear to be important in anticonvulsants are enhancement of GABA action and inhibition of sodium channel activity. Other mechanisms are inhibition of calcium channels and glutamate receptors.

Diuretics are drugs that increase the volume of urine produced by promoting the excretion of salt and water from the kidneys. There are several types of diuretics, each working in a distinct way.

Loop diuretics prevent re-absorption of sodium and chloride ions in the Loop of Henle. Thiazide diuretics inhibit sodium re-absorption at the beginning of the distal convoluted tubules. Potassium sparing diuretics prevent excessive loss of potassium at the distal convoluted tubules.

Diuretics are used to reduce the edema caused due to salt and water retention in disorders of the heart, kidneys, liver or lungs. They are used commonly in treatment of hypertension.

Topical dermatological agents are applied directly on the skin to treat skin conditions. They may deliver medicines to prevent or treat skin disorders or have inert creams and ointments for routine skin care to maintain the skin, which may be susceptible to skin disorders.

Topical dermatological agents include local anesthetics, cleansing agents, anti-inflammatory agents, anti-infective agents, emollients, astringents, agents to treat acne, anti-virals, anti-fungals, agents for psoriasis such as topical corticosteroids, and so on.

Digestive enzymes are products that contain enzymes, which are necessary during digestion to break down the food. These enzymes are either present in or released into the gastrointestinal tract.

Digestive enzyme products are given orally to patients who do not produce the particular enzymes; therefore without these they will be unable to digest and absorb the food properly.
