Haldol indications

Haloperidol is a typical butyrophenone type antipsychotic that exhibits high affinity dopamine D 2 receptor antagonism and slow receptor dissociation kinetics. [42] It has effects similar to the phenothiazines . [18] The drug binds preferentially to D 2 and α 1 receptors at low dose (ED 50 = and  mg/kg, respectively), and 5-HT 2 receptors at a higher dose (ED 50 =  mg/kg). Given that antagonism of D 2 receptors is more beneficial on the positive symptoms of schizophrenia and antagonism of 5-HT 2 receptors on the negative symptoms, this characteristic underlies haloperidol's greater effect on delusions, hallucinations and other manifestations of psychosis. [43] Haloperidol's negligible affinity for histamine H 1 receptors and muscarinic M 1 acetylcholine receptors yields an antipsychotic with a lower incidence of sedation, weight gain, and orthostatic hypotension though having higher rates of treatment emergent extrapyramidal symptoms .

Unusual cancers have been reported in children and teenage patients taking TNF-blocker medicines. Hepatosplenic T-cell lymphoma, a rare form of fatal lymphoma, has occurred mostly in teenage or young adult males with Crohn's disease or ulcerative colitis who were taking REMICADE® and azathioprine or 6-mercaptopurine. For children and adults taking TNF blockers, including REMICADE®, the chances of getting lymphoma or other cancers may increase. You should discuss any concerns about your health and medical care with your doctor.

One dopamine agonist, apomorphine (Apokyn), is a powerful and fast-acting injectable medication that promptly relieves symptoms of PD within minutes, but only provides 30 to 60 minutes of benefit. With training provided by the PD specialist, people with PD, spouses and family members can be taught to administer the agent, using a pre-filled syringe system. Its main advantage is its rapid effect. It is used for people who experience sudden wearing-off spells when their PD medication abruptly stops working, leaving them unexpectedly immobile. Apomorphine may cause severe nausea, and so people using this agent must take an antiemetic agent. In addition, apomorphine can provoke dyskinesias and other side effects associated with dopamine drugs.
