Claims for the superiority of various calcium supplements are now appearing on television and in the print media. A high calcium intake combined with vitamin D can increase bone density and reduce the incidence of fractures in older women and probably also in men.

A recent supplement to the Journal of Clinical Psychiatry, titled "The Expert Consensus Guideline Series: Optimizing Pharmacologic Treatment of Psychotic Disorders," concluded that most experts endorsed use of second-generation (atypical) antipsychotics rather than first-generation drugs, with risperidone (Risperdal - Janssen) the top choice for first episodes, multiple episodes or switches from another drug (JM Kane et al, J Clin Psychiatry 2003; 64 suppl 12:5). The supplement was sponsored by Janssen.

Oral antipsychotic drugs used for treatment of schizophrenia, schizoaffective disorder, delusional disorder, and other manifestations of psychosis or mania are listed in Table 1. Parenteral antipsychotic drugs used for treatment of these disorders are listed in Table 2.

Quetiapine (Seroquel - Zeneca), a dibenzothiazepine derivative, has been approved by the FDA for treatment of schizophrenia and other psychotic disorders. It is a new addition to the 'atypical' antipsychotics, which include olanzapine (Zyprexa - Medical Letter, 39:5, 1997), risperidone (Risperdal) and clozapine (Clozaril). Atypical antipsychotic drugs generally are less likely to cause extrapyramidal symptoms than older drugs such as haloperidol (Haldol, and others) or the phenothiazines.

Recombinant human deoxyribonuclease I (rhDNase; dornase alfa; Pulmozyme - Genentech), an enzyme that hydrolyzes extracellular DNA, is now available as a purified solution to decrease the viscosity of sputum in patients with cystic fibrosis. It requires a nebulizer to produce an aerosol mist for inhalation.

Olanzapine (Zyprexa - Lilly), a thienobenzodiazepine that structurally resembles and binds to many of the same receptors as clozapine (Clozaril), is now available in the USA for treatment of schizophrenia and other psychotic disorders.

Liquid diets for weight reduction, once discredited because of their adverse effects, are becoming popular again. Now, formula diets are available through physicians or hospitals as part of a packaged weight-reduction program that includes nutrition education and modification of eating and exercise habits. Three widely used programs are Optifast (Sandoz), Medifast (Nutrition Institute of Maryland, 1840 York Road, Timonium, MD 21093) and HMR (Health Management Resources, 59 Temple Place, Boston, MA 02111).

Nefazodone (Serzone - Bristol-Myers Squibb) was recently approved by the US Food and Drug Administration for treatment of depression. A phenylpiperazine, nefazodone is chemically related to trazodone (Desyrel, and others).

Silodosin (Rapaflo - Watson Pharmaceuticals), an alpha1a-adrenoreceptor selective antagonist, has been approved by the FDA for treatment of benign prostatic hyperplasia (BPH). Some medications for BPH are listed in the table on page 4. Alpha1 blockers are commonly used with 5a-reductase inhibitors such as finasteride, which can shrink the size of the prostate, but may take months to do so.

Deep brain stimulation (DBS) is increasingly used to treat advanced Parkinson's disease (PD), but few controlled clinical trials have been published. New evidence from a large controlled study has recently become available.
