Anticholinergic Syndrome: Adverse drug effects associated with CHOLINERGIC ANTAGONISTS. Clinical features include TACHYCARDIA; HYPERTHERMIA; MYDRIASIS, dry skin and dry mucous membranes, decreased bowel sounds and urinary retention in peripheral anticholinergic syndrome; and HALLUCINATIONS; PSYCHOSES; SEIZURES; and COMA in central anticholinergic syndrome.Lavandula: A plant genus of the LAMIACEAE family.Cholinergic Antagonists: Drugs that bind to but do not activate CHOLINERGIC RECEPTORS, thereby blocking the actions of ACETYLCHOLINE or cholinergic agonists.Syndrome: A characteristic symptom complex.Trihexyphenidyl: One of the centrally acting MUSCARINIC ANTAGONISTS used for treatment of PARKINSONIAN DISORDERS and drug-induced extrapyramidal movement disorders and as an antispasmodic.Parasympatholytics: Agents that inhibit the actions of the parasympathetic nervous system. The major group of drugs used therapeutically for this purpose is the MUSCARINIC ANTAGONISTS.BenzilatesBiperiden: A muscarinic antagonist that has effects in both the central and peripheral nervous systems. It has been used in the treatment of arteriosclerotic, idiopathic, and postencephalitic parkinsonism. It has also been used to alleviate extrapyramidal symptoms induced by phenothiazine derivatives and reserpine.Orphenadrine: A muscarinic antagonist used to treat drug-induced parkinsonism and to relieve pain from muscle spasm.Scopolamine Derivatives: Analogs or derivatives of scopolamine.Ipratropium: A muscarinic antagonist structurally related to ATROPINE but often considered safer and more effective for inhalation use. It is used for various bronchial disorders, in rhinitis, and as an antiarrhythmic.
