Premature ejaculation (PE) is the most common sexual problem affecting men. It can affect men at all ages and has a serious impact on the quality of life for men and their partners. Currently there are no pharmaceutical agents approved for use in the UK, and so all drugs used for this condition are off label. Behavioral therapy has been used to treat PE, but the results are not durable once the...

BACKGROUND Botulinum toxin type A (BTX-A) injections are an effective treatment for controlling hyperhidrosis at sites of amputation. Hyperesthesia associated with amputated limbs is a major barrier to performing this procedure under local anesthesia. OBJECTIVE To present a novel method for improving local anesthesia with BTX-A injections. Methods & RESULTS A 29-year-old military vetera...

Infrared difference spectroscopy has been used to examine the structural effects of local anesthetic (LA) binding to the nicotinic acetylcholine receptor (nAChR). Several LAs induce subtle changes in the vibrational spectrum of the nAChR over a range of concentrations consistent with their reported nAChR-binding affinities. At concentrations of the desensitizing LAs prilocaine and lidocaine con...

BACKGROUND The author reviewed the history of, federal regulations regarding, risks of and adverse drug reactions of five compound topical anesthetics: tetracaine, adrenaline/epinephrine and cocaine (TAC); lidocaine, adrenaline/epinephrine and tetracaine (LET); lidocaine, tetracaine and phenylephrine (TAC 20 percent Alternate); lidocaine, prilocaine and tetracaine (Profound); and lidocaine, pri...

BACKGROUND Felypressin has been added to local anesthetic to increase the length of the anesthetic effect and reduce toxicity during dental procedures. However, the effect on blood pressure remains uncertain, and this may be highly relevant in the dental treatment of hypertensive patients. OBJECTIVE To investigate the effect of felypressin on blood pressure in hypertensive patients with contr...

BACKGROUND Given large number of patients with hypertension attending dental clinics and the profound effects of local anesthetics containing vasoconstrictors, this study aimed to compare the effects of lidocaine 2% + epinephrine, prilocaine 3% + felypressin0.03, and mepivacaine 3% on blood pressure changes. METHODS The current study was carried out from May 2014 to February 2015.Patients wit...

The time from the end of surgery to the administration of the first post-operative analgesic has been measured in 86 patients following brachial plexus block with bupivacaine, lignocaine, nepivacaine or prilocaine. A signficant increase in time occurred with bupivacaine; the combination of regional and general anesthesia significantly increased the time when compared with general anaesthesia in...
