The same may apply to a combination of valproate and 3518 chitosan discount 80mg propranolol with visa capillaries exchange what, a common dieting agent discount propranolol 80 mg free shipping heart disease age 65. The combination of clonazepam and valproate may induce absence status in those patients with a history of absence seizures cheap propranolol 80 mg with visa coronary heart disease kills. Valproate has been combined with lithium and even with a combination of lithium and carbamazepine generic 40 mg propranolol amex cardiovascular prophylaxis icd 9. It has been found to improve responsivity of refractory affective disorders (not necessarily including rapid cycling: Calabrese ea, 2005) to lithium or carbamazepine when it is added to the regimen. Lamotrigine (Lamictal dispersible tablets) A phenyltriazine that was noted to improve mood in epileptics, lamotrigine is thought to work in bipolar disorder by inhibiting excitatory presynaptic neurotransmitter release, especially glutamate. Peak plasma concentration occurs 2-3 hours after ingestion, the half-life is about 30 hours, 55% is protein bound, bioavailability is 98%, first-pass metabolism is minimal, and an inactive glucuronide metabolite is formed in the liver and excreted in the urine. Severe alopecia may necessitate stopping the drug and hair re-growth (tends to be curly) may then take several months. Most lamotrigine-related rashes (occurring in 10% of 3528 patients) are of little clinical importance, but because rare cases can be very serious , such as Stevens-Johnson syndrome or toxic epidermal necrolysis, it has been suggested that rash is an indication for stopping the drug. Certainly, where the face is extensively 3529 involved, where there is evidence of mucous membrane involvement , or where there 3530 are systemic symptoms there is no choice but to stop the drug and to treat the case as an emergency. There are rare reports of blood and liver problems, which cannot as yet be directly attributed to lamotrigine. A few cases of breakthrough seizures, unexpected 3531 3532 pregnancies and of menstrual bleeding disorders have been reported to GlaxoSmithKline in women on a combination of lamotrigine and the contraceptive pill. Anovulants decrease serum levels of lamotrigine and such levels may there rise on 3533 stopping the contraceptive pill. The half-life of lamotrigine is doubled by valproate and halved by phenytoin and carbamazepine. Duncan ea (1998) called for more detailed studies of lamotrigine use in the affective disorders. A small, open, non-randomised report of lamotrigine being effective when added to clozapine in partially clozapine-responsive patients was conducted by Dursun and McIntosh. Also, it was of limited efficacy in delaying time to manic/hypomanic episodes but it significantly delayed time to intervention for a depressive episode. Junker and Stodieck (1997) reported a case of lamotrigine-responsive clozapine-induced myoclonus. The starting dose is 25 mg daily for 2 weeks, followed by 50 mg daily for 2 weeks, gradually increasing to 200 mgs daily over 6 weeks (range in bipolar disorder: 50-300 mg/day). Isoptin, Verap) Verapamil, a class I calcium antagonist, may be a useful treatment in acute mania. Gabapentin (Neurontin) Despite positive case reports, trials do not support use of this drug in the treatment of 3534 bipolar disorder. It has found a niche in the management of anxiety, pain, and substance use disorders. Antipsychotic drugs Esparon ea (1986) performed a double blind crossover trial of depot flupenthixol (flupentixol) in recurrent manic-depression. Flupenthixol is nevertheless employed in depot injectable form in non-compliant patient with recurrent affective disorders by many clinicians. Clonidine (Catapres, Dixarit) Giannini ea(1986) found lithium to be more effective than clonidine in manic patients. Sachs (1990) reported early claims that clonazepam reduced cycle frequency in bipolar affective disorder, was associated with fewer depressive episodes than when antipsychotic drugs were employed, and that neuroleptic-lithium combinations could be switched to a clonazepam-lithium combination without leading to an acute relapse. Drug use in the elderly This important subject is dealt with here for convenience. Various factors affect drug disposition in old people: age-related physiological changes, pathology, and therapeutic 3536 and environmental factors. Age-related physiological changes include absorption , 3537 3538 3539 distribution , metabolism , and excretion. Some guidelines for prescribing drugs in the elderly Take a careful drug history and check for use of over-the-counter drugs Be familiar with the effects of age on the pharmacology of drugs Strive to make a diagnosis before instituting therapy Use smaller starting doses Adjust the dose according to response Review the drug treatment plan regularly and keeping it simple Be alert to the possibility of iatrogenic illness Beware interactions between disease states and drugs. Older people and children should normally commence on one- 3542 half to one-third of the adult starting dose. A trial using adequate doses of antidepressants must be undertaken before describing depression as refractory, e. A therapeutic trial of an antidepressant should last for at least 6 weeks, with at least 4 weeks on the highest tolerated safe dose. Side effects will be better tolerated if it is explained that these are usually transient and that the drug will be reduced if significant improvement does not occur in about 6 weeks. Maintenance treatment at the therapeutic dose for at least 6 months and then slowly reduced in case the episode of depression has not abated. The early stages of 3544 recovery from depression may be accompanied by a sufficient return of volition to 3545 make suicide a real possibility. Studies of suicides suggest that antidepressants are either not prescribed at all or are given in sub-optimal dosage in many cases of depressive illness. The serum concentrations of antidepressants show a wide individual variation, are increased by antipsychotic drugs and are decreased by barbiturates. Depression in the elderly requires for its proper treatment a consideration of its wide variety of associated aetiological factors. The reader is advised to check an up to date data sheet from the manufacturer before prescribing a drug, especially where he or she is not very familiar with the product – this advice applies to all 3546 pharmaceuticals. Downregulation of 3540 A study of psychiatrists’ outpatient prescribing practices in Rhode Island during 2001-2(Zimmerman ea, 2004) showed that their main considerations were avoiding specific side effects (espc. Researchers hold that one-third of patients placed on antidepressant drugs are non-responders, one- 3547 third are placebo responders, and the final third constitute responders. Desipramine is a very strong re-uptake inhibitor of nor-adrenaline whereas clomipramine is a powerful 3547 The last third are said to occupy the ‘efficacy window’. The narrowness of this window suggests that increased or decreased efficacy in comparative studies have to be large in order to be detected. Side chain demethylation converts tertiary amines to secondary amines and the latter to 3549 (inactive) primary amines. Sudden cessation of tricyclics can lead to restless agitation, insomnia, headaches, vomiting and hyperhidrosis. O’Brien and Oyebode (2003) have discussed the Brugada syndrome, a disorder of the 3551 Na+ channel and a cause of death (espc. During the period 1993-7 in England and Wales 20% of all deaths from overdose and poisoning were antidepressant related. Whilst the number of such deaths increased by 18% during the same period, prescriptions for these drugs increased three times. The highest death rates were in males aged 30-44 years and in females aged 45-59 years. The statistical strength of the therapeutic window concept is generally too weak to have much influence on clinical practice. Cardiotoxicity reaches significant proportions in people with pre-existent heart problems and in overdose.

Owing to 28 its cholagogic action order 40 mg propranolol with visa arteries carry blood away from heart, the herb can induce acute abdominal pain in patients 29 with gallstones. Analgesic effects after application on the 39 temples in tension headache could be proven in clinical studies. Persons who tend to develop gastroesophageal reflux should avoid pep- 43 permint oil. Because of its menthol content, peppermint oil has a weak 45 potential for sensitization. The preparation consists of the es- 9 sential oil derived from the fresh needles and branch tips collected in the 10 springtime of Pinus sylvestris L. Individuals with ex- 34 tensive wounds, acute skin diseases, febrile and infectious diseases, heart fail- 35 ure and/or hypertension should not use pine oils as a bath additive.

The herb consists of the fresh or dried 13 sprouts (3–5 cm in length) ofPinus sylvestrisL. Resins, 17 bitter principles, pinicrin, and ascorbic acid (vitamin C) are also present. The herb consists of the 43 dried, entire flowers (with calyx) of Primula veris L. Plant Summaries—P • Primula root: 5–10% triterpene saponins (primula acid A), phenol gly- 1 cosides (0. In animal studies, the herb 6 was found to increase the volume of bronchial secretions. The 44 swelling index of the preparations used in medicine should be no less than 45 10. The stool volume increases, the transit time 50 Plant Summaries—P 1 decreases (a desirable effect in constipation), and intestinal peristalsis is 2 stimulated. When used to treat diarrhea, the herb leads to fluid binding, 3 thereby normalizing the transit time. Allow whole or coarsely crushed seeds to swell 15 in water, then take with plenty of water (150 mL for each 5 g of the drug). A physician should be con- 19 sulted in any case when diarrhea lasts for more than 3 to 4 days. Blockage of the esophagus or 22 intestine and choking attacks can occur if the patient, especially when elderly, 23 does not take an ample supply of water. Psyllium polysaccharides can increase the effects of insu- 27 lin or oral antidiabetic drugs. In humans, 49 they have analgesic effects in headaches caused by nervous tension and are 50 effective in treating psychasthenic neuroses. Plant Summaries—P Warning: When pyrrolizidine alkaloid-containing herbs are adminis- 1 tered at high doses or chronically, they can induce hepatotoxic, muta- 2 genic, teratogenic, and carcinogenic effects. In 9 that case, they should be used according to the instructions supplied by the 10 manufacturers. Industrial manufacturers 13 are able to prepare extracts that are (virtually) pyrrolizidine alkaloid-free. The seeds are a foodstuff, but are also used as an herb- 26 al remedy for prostate and irritable bladder complaints. The experimental data are hardly sufficient to docu- 37 ment the clinical efficacy of the herb. There is empirical evidence of the ef- 38 ficacy of the herb in treating prostatic hyperplasia but clinical studies are 39 still not sufficient. Reserpine, one of its alkaloids, is used in multidrug antihyperten- 35 sive medications. The herb consists of the dried, fleshy, central 47 bulb sections of the white onion species Urginea maritima (L. These include increased muscle tone in the gastrointestinal region, 28 lack of appetite, nausea, diarrhea, headaches, and irregular pulse. Rinse the mouth or gargle with the fresh- 19 ly prepared infusion 2 to 3 times a day. The leaves consist of the fresh or 33 dried foliage leaves of Rosmarinus officinalis L. Diterpe- 37 nes (bitter-tasting substances), caffeic acid derivatives (rosmarinic acid), 38 flavonoids, and triterpenes are also present. In animals, the 41 herb was found to have spasmolytic (biliary tract, small intestine), chole- 42 retic, and hepatoprotective effects. In humans, rosemary oil irritates the 43 skin and increases the circulation when applied topically. The herb consists of the fresh or dried foli- 5 age leaves of Salvia officinalis L. Caffeic 8 acid derivatives (3–6%) consisting mainly of rosmarinic acid and chloro- 9 genic acid. The tannins (rosmarinic 15 acid) have anti-inflammatory, astringent, and antihydrotic effects.
