The skeletal muscle relaxants are contraindicated in patients with known hypersensitivity. Baclofen is contraindicated in skeletal muscle spasms caused by rheumatic disorders. Carisoprodol is contraindicated in patients with a known hypersensitivity to meprobamate. Cyclobenzaprine is contraindicated in patients with a recent myocardial infarction, cardiac conduction disorders, and hyperthyroidism, hi addition, cyclobenzaprine is contraindicated within 14 days of the administration of a monoamine oxidase inhibitor. Oral dantrolene is contraindicated in patients with active hepatic disease and muscle spasm caused by rheumatic disorders and during lactation. See Chapter 30 for information on diazepam. 

These dm are contraindicated in patients with a hypersensitivity to the dragp and during pregnancy (Category C) and lactation. Tolcapone is contraindicated in patients with liver dysfunction. The COMT inhibitors are used with caution in patients with hypertension, hypotension, and decreased hepatic or renal function.

Category X) and lactation. The HMG-CoA reductase inhibitors are used cautiously in patients with a history of alcoholism, acute infection, hypotension, trauma, endocrine disorders, visual disturbances, and myopathy. 

The proton pump inhibitors are contraindicated in patients who have hypersensitivity to any of the drags. Omeprazole (Pregnancy Category C) and lansoprazole, rabeprazole, and pantoprazole (Pregnancy Category B) are contraindicated during pregnancy and lactation. The proton pump inhibitors are used cautiously in older adults and in patients with hepatic impairment.

After birth, a rapid drop in progesterone level initially triggers lactation through reversal of inhibitory effects on prolactin (Fig. 44-2). Nipple stimulation then enables lactation to continue once established. During lactation, ineffective removal of milk from the breast, trauma, and skin breaks may lead to problems such as milk stasis, nipple pain, and mastitis.12 Additionally, some women have difficultly initiating lactation due to improper technique and/or activity of inhibitors such as dopamine (Fig. 44-2). 

Yet different elaboration of the same molecule affords a compound (162) that acts as an inhibitor to the pituitary peptide hormone prolactin, the factor responsible for supporting lactation. As such the drug has found use in suppressing lactation and in the treatment of prolactin-dependent breast tumors.

Bupropion belongs to the chemical class of aminoketones. It is an atypical antidepressant that acts as a norepinephrine and dopamine reuptake inhibitor, and nicotinic antagonist. Initially developed and marketed as an antidepressant, bupropion was subsequently found to be effective as a smoking cessation aid. If given to lactating women it can trigger convulsions in the newborn. 

Malathion is an organophosphate cholinesterase inhibitor. Up to 8% of the topically applied dose may be absorbed. Malathion is used as a treatment for head lice, body lice and scabies. It effectively kills both the eggs and the adult lice. Malathion is an insecticide of relatively low human toxicity. However if malathion is used in an indoor environment, as it breaks down into malaoxon, it can be seriously and chronically poisonous. The safety of malathion in pregnancy and in lactating women and in children has not been established. 

Lee et al. (1978) investigated the possibility that sulfhydryl groups were required in the formation of the clostridial inhibitor in cured meats. Sulfhydryl groups of meat proteins were blocked by treatment with silver lactate, then the samples were cooked with sodium nitrite before inoculation with C. botuli num spores. Botulinal growth as measured by gas and toxin production was similar to controls without silver lactate treatment. They thus concluded that sulfhydryl groups were not required for the antibotulinal effects of nitrite in cured meats.

Reductase inhibitors are useful alone or with resins, niacin, or ezetimibe in reducing levels of LDL. Women with hyperlipidemia who are pregnant, lactating, or likely to become pregnant should not be given these agents. Use in children is restricted to selected patients with familial hypercholesterolemia or familial combined hyperlipidemia.
