In the healthy individual buy mentat ds syrup 100 ml overnight delivery, tonic release of dopamine into this system inhibits the release of prolactin discount 100 ml mentat ds syrup overnight delivery. Unintentional disruption of this system leads to elevation of serum prolactin and the side-effects of gynecomastia, galactorrhea and sexual dysfunction. However, particular psychiatric medications are often used for disorders outside their “classification”. For example, the selective serotonin reuptake inhibitors (SSRIs) which were initially marketed as antidepressants, have become the drugs of first choice in most anxiety disorders and OCD, and the tricyclic antidepressants (TCAs) are used in bed-wetting (enuresis) because their anticholinergic “side-effects” cause tightening of the bladder neck. The so-called “side-effects” of drugs may sometimes be useful, for example, people with major depressive episodes who have difficulty with sleep may benefit from an antidepressant with sedating “side-effects” being given at night. Interestingly, LSD (lysergic acid diethylamide) and Ecstasy, now considered dangerous and illegal, have both been considered as potential psychiatric treatments. They are the mainstay of the treatment of schizophrenia and will be discussed below in that context. However, they are also the mainstay of the management of delusional disorder, psychosis which occurs in dementia, they have a place in the management of delirium, and they must be added to antidepressants for the successful management of psychotic depression. The antipsychotics have a central place in the management of acute mania (even in the absence of delusions and hallucinations). Olanzapine, aripiprazole and others have gained acceptance as mood stabilizers (prophylactic Pridmore S. Quetiapine has been approved by the FDA (USA) as a treatment for bipolar depression (Dando & Keating, 2006). In rare cases antipsychotics are used in the management of insomnia and anxiety (Carson et al, 2004), but this is not recommended and is best left to experts. THE TYPICAL ANTIPSYCHOTICS The typical antipsychotic drugs were the first effective antipsychotics. Chlorpromazine was the first, being described by French doctors in 1952. Others followed, including: haloperidol, fluphenazine and thiothixene. There is a straight line relationship between the affinity of the typical antipsychotics for the dopamine D2 receptor and the therapeutic dose of these agents used in acute schizophrenia. This is consistent with the dopamine hypothesis of schizophrenia Illustration. This straight line relationship supports the dopamine hypothesis of schizophrenia. Side-effects of typical antipsychotics The extrapyramidal system (EPS) - the EPS is not a side-effect of antipsychotics, but needs to be mentioned before certain side effects. The EPS is a component of the motor system composed of dopamine (DA) and acetylcholine (Ach) neurons which enjoy a reciprocal/balanced relationship. In some individuals when DA receptors are blocked, the balance in the system is disrupted, leading to side-effects. This is particularly a feature of the older, First Generation Antipsychotics (FGAs). These can appear on the first day of treatment and can take various forms of involuntary muscle spasm, particularly involving of the jaw, tongue, neck and eyes. A dramatic form is oculogyric crisis – in which the neck arches back and the eyes roll upward. Balance has been disturbed resulting in muscle spasm, and can be restored by acute treatment with oral or intramuscular injection of an anti-Ach – such as benztropine (2 mg). Medium-term neurological side-effects are also due to D2 blockade in the EPS. Akathisia usually occurs in the first few day of treatment and involves either a mental and/or motor restlessness. Mental restlessness presents as increasing distress and agitation. Motor restlessness usually affects the lower limbs, with shifting from one foot to the other while standing and constant crossing and uncrossing of the legs while sitting. Useful steps include lowering the dose of the antipsychotic (if possible), adding diazepam or propranolol, or adding an anticholinergic (none of these is dramatically effective). Parkinsonism usually occurs some days or weeks after the commencement of treatment. There is a mask-like face, rigidity of limbs, bradykinesia, and loss of upper limb-swing while walking. The best management is reduction in dose of the antipsychotic (if possible) and the addition of an anticholinergic agent. Chronic neurological side-effects (late EPS effects) usually occur after months or years of continuous D2 blockade. Tardive dyskinesia (TD) manifests as continuous choreoathetoid movements of the mouth and tongue, frequently with lip-smacking, and may also involve the head, neck and trunk. Late EPS effects may continue after cessation of the typical antipsychotic.
