Dimenhydrinate is indicated for the prevention and treatment of nausea, vomiting, or vertigo of motion sickness.
Dimenhydrinate is indicated for the prevention and treatment of nausea, vomiting, or vertigo of motion sickness. It has a short duration of action of 4-8 hours. Patients should be counselled regarding pronounced drowsiness, avoiding alcohol and other sedatives, and exercising caution when operating a motor vehicle or heavy machinery.
Antiemetics
Drugs used to prevent NAUSEA or VOMITING. (See all compounds classified as Antiemetics.)
Histamine H1 Antagonists
Drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine. Included here are the classical antihistaminics that antagonize or prevent the action of histamine mainly in immediate hypersensitivity. They act in the bronchi, capillaries, and some other smooth muscles, and are used to prevent or allay motion sickness, seasonal rhinitis, and allergic dermatitis and to induce somnolence. The effects of blocking central nervous system H1 receptors are not as well understood. (See all compounds classified as Histamine H1 Antagonists.)

Absorption
A 50 mg oral film coated tablet reaches a Cmax of 72.6 ng/mL with a Tmax of 2.7 hours. A 100 mg suppository reaches a Cmax of 112.2 ng/mL with a Tmax of 5.3 hours.
Route of Elimination
Dimenhydrinate is predominantly eliminated in the urine. 1-3% of the dissociated diphenhydramine is eliminated in the urine unchanged, while 64% of diphenhydramine is eliminated in the urine as metabolites. The elimination of dimenhydrinate has not been fully studied.
Volume of Distribution
The volume of distribution of dimenhydrinate is 3-4 L/kg.

Dimenhydrinate is a theoclate salt that separates into [diphenhydramine] and [8-chlorotheophylline]. diphenhydramine can either be N-glucuronidated by UGTs to diphenhydramine N-glucuronide or N-demethylated by CYP2D6, CYP1A2, CYP2C9, and CYP2C19 to N-desmethyldiphenhydramine. N-desmethyldiphenhydramine can be N-demethylated again by the same enzymes to N,N-didesmethyldiphenhydramine, which undergoes oxidative deamination to form diphenylmethoxyacetic acid.

The plasma elimination half life of dimenhydrinate is 5-8 hours.
Dimenhydrinate is a theoclate salt that separates into [diphenhydramine] and [8-chlorotheophylline]. While the exact mechanism of action is unknown, diphenhydramine is theorized to reduce disturbances to equilibrium through antimuscarinic effects or histamine H1 antagonism. 8-chlorotheophylline may produce excitation through blocking adenosine receptors, reducing the drowsiness produced by diphenhydramine.
