Cmax in plasma is achieved on average 2 hours after ingestion. T1 / 2 - about 10 hours. Absorption is high, metabolized in the liver. Well penetrates through the histohematological barriers (including GEB). It is excreted by 60% kidneys unchanged, partially through the digestive tract.

Special patient groups

In patients older than 65 years, as well as with hepatic and renal insufficiency, T1 / 2 may increase. When the course of treatment is repeated, the stable concentration of the drug and its metabolites in the blood plasma is reached later and at a higher level.

With care: patients with cases of apnea in history (due to the fact that doxylamine succinate can aggravate the syndrome of nocturnal apnea - a sudden stop of breathing in a dream); Patients over 65 years of age (due to possible dizziness and delayed reactions with a risk of falling (for example, during night awakenings after taking sleeping pills), as well as in connection with a possible increase in T1 / 2, patients with renal and hepatic insufficiency (T1 / 2 may increase) .

From the CVS: a feeling of palpitations.

From the side of the organ of vision: visual impairment and accommodation, vague sight.

From the side of the kidneys and urinary tract: urinary retention.

From the nervous system: drowsiness during the day (in this case, the dose of the drug should be reduced), confusion, hallucinations.

On the part of laboratory indicators: an increase in the level of CK.

From the musculoskeletal system: rhabdomyolysis.

If any of these side effects are aggravated or any other side effects not listed in the description are noted, the doctor should be informed.


With concurrent administration of DonormylŪ with sedative antidepressants (amitriptyline, doxepin, mianserin, mirtazapine, trimipramine), barbiturates, benzodiazepines, clonidine, morphine derivatives (analgesics, antitussives), neuroleptics, anxiolytics, sedative H1-antihistamines, central antihypertensive drugs, Thalidomide, baclofen, and pisotifenum, the inhibitory effect on the central nervous system increases.
